TECHNICAL FIELD
[0001] The present disclosure relates to oral smokeless moist snuff products containing
particles, such as microparticles, for flavor release. The disclosure also relates
to methods for making such products and uses thereof.
BACKGROUND
[0002] Smokeless tobacco for oral use includes chewing tobacco, dry snuff and moist (wet)
snuff. Generally, dry snuff has moisture content of less than 10 wt% and moist snuff
has a moisture content of above 40 wt%. Semi-dry products having between 10% to 40
wt% moisture content are also available.
[0003] Smokeless tobacco products for oral use are made from tobacco leaves, such as lamina
and stem of the tobacco leaf. The material from roots and stalks are normally not
utilized for production of smokeless tobacco compositions for oral use.
[0004] There are two types of moist snuff, the American type and the Scandinavian type.
American-type moist snuff is available in a loose form or as pre-packed pouches and
is typically used between the lower gum and lip. The use of American-type moist snuff
is commonly called dipping. Snus is the Scandinavian-type of moist snuff which is
also available in loose form or as pre-packed portions in pouches. Snus is typically
used between the upper gum and lip.
[0005] American-type moist snuff is commonly produced through a fermentation process of
moisturized ground or cut tobacco. Scandinavian-type moist snuff (snus) is commonly
produced by using a heat-treatment process (pasteurization) instead of fermentation.
The heat-treatment is carried out in order to degrade, destroy or denature at least
a portion of the microorganisms within the tobacco preparation. In production processes
typically used today for producing pouched snus products, the tobacco preparation
subjected to this heat-treatment process normally has moisture content within the
range of from about 22 to 44% w/w. Generally, additional water, salt, pH adjuster
and additional ingredients, such as flavours, are added to the tobacco preparation
after this heat-treatment in order to provide the final smokeless tobacco composition,
such as the moist snuff.
[0006] The main ingredients of oral smokeless moist snuff are tobacco, water, sodium carbonate,
sodium chloride and a humectant such as propylene glycol or glycerol. Often a flavorant
is present to enhance the organoleptic experience by a consumer. Instead of tobacco,
fibres of non-tobacco plant material may be used thereby providing an oral smokeless
non-tobacco product.
[0007] There are a number of properties of the oral smokeless moist snuff that are very
important for the end user. Among them, the organoleptic properties, such as texture,
aroma, taste, form and package of the product are of high importance for the consumer.
A way of changing and/or improving the sensory experience by a consumer is to add
a flavorant to the tobacco material. For instance, the flavorant may be added by mixing
it with the tobacco material. When the oral smokeless tobacco product is placed in
a consumer's oral cavity the natural tobacco flavor and/or the added flavorant will
be extracted by the consumer's saliva. The flavorant is extracted gradually. After
a certain time, such as about one hour, the consumer usually perceives the taste as
gone and therefore disposes the product. It would be desirable that the flavor intensity
experienced by a consumer remained constant or increased during a certain time period.
[0008] Alternatively or additionally, the flavorant may be added to the tobacco formulation
in a form that physically separates it from the tobacco formulation. For instance,
particles containing a flavorant may be added. The particles containing a flavorant
may be provided as a capsule, such as a encapsulated. Disintegration of the capsule
leads to flavor release. The capsules may be designed so that flavor release only
takes place when certain conditions are fulfilled. For instance, the capsules may
be temperature sensitive so that a certain temperature is required for capsule disintegration
and concomitant flavor release. Further, encapsulation of the flavorant prevents it
from interacting with the tobacco composition and/or the atmosphere in the container
for the tobacco composition. Such interaction may lead to a different and/or deteriorated
sensorial experience and have a negative impact on stability.
[0009] The use of flavorant containing microcapsules in dry snuff is known. Commonly, the
microcapsule shell comprises gelatine. During storage in a refrigerator or at room
temperature (i.e. about 22 °C) the gelatine shell maintains its integrity and does
not release the flavorant. When a consumer places the dry snuff containing the microcapsules
into the mouth the gelatine capsules disintegrate and the flavorant is released.
[0010] Use of encapsulated flavorants for flavorization of oral smokeless moist snuff products
presents a particular challenge. One the one hand, the capsule material must maintain
its integrity and substantially withstand leakage of the enclosed flavorant when mixed
and stored together with the moist tobacco composition. On the other hand, the capsule
material should be able to disintegrate and provide controlled release of the flavorant
when the oral smokeless moist snuff product is placed in a user's mouth.
[0011] US patent No. 7,810,507 discloses a smokeless tobacco product containing microencapsulated flavorants. A
list of outer wall or shell material of the microcapsules is mentioned, said list
including inter alia gelatine and hydroxypropyl methylcellulose. It is stated that
microencapsulated tobacco flavorants will provide extended release of the tobacco
flavor under conditions of normal use of the smokeless tobacco product, such as under
conditions of 45% or greater moisture level, based on the total weight of the smokeless
tobacco product. Alternatively, they may lose their physical integrity when the smokeless
tobacco product reaches a certain pH or a certain temperature.
[0012] US 2004/0180067 discloses a particle composition containing a continuous phase of 5-95% organically
soluble cellulosic material selected from the group consisting of ethyl cellulose
and hydroxypropyl cellulose dissolved in 5-95% organic fragrance chemicals and organic
flavor chemicals. It is stated that a particle formed of hydroxypropyl cellulose and
flavor will not dissolve in an aqueous solution of 10% NaCl, although flavor chemicals
will partition into the aqueous phase over time.
[0013] WO 2009/073190 discloses a fast-dissolving film for use as a platform for the delivery of material
to the oral cavity, comprising a film forming agent, a plasticizing agent and a water-soluble
agent. The material may be nicotine. The film may be edible and is fast-dissolving
upon contact with water-based aqueous systems such as human saliva.
[0014] WO2009/056609 discloses oral smokeless tobacco compositions comprising encapsulated flavorants.
The encapsulating agent is hydrophobic and poorly soluble in aqueous solutions.The
release of the flavourant may be caused by alteration/degradation of the encapsulating
agent with saliva and/or thermal degradation, e.g. melting of the encapsulation agent
at a temperature present in the oral cavity.
[0015] US 2010/0282267 discloses an encapsulated flavorant for use with smokeless tobacco. The encapsulated
flavorant comprises a core with a lipid-based coating that provides stability when
in contact with tobacco, yet releases flavor over time when the product is used.
[0016] It is an object of the present disclosure to overcome or at least mitigate some of
the problems associated with flavorization of oral smokeless moist snuff. Further,
it is an object of the present disclosure to provide an oral smokeless moist snuff
product exhibiting satisfactory storage stability, such as satisfactory storage stability
with respect to flavor. It is also an object of the present disclosure to provide
an oral smokeless moist snuff product with attractive flavor characteristics.

[0017] There is provided an oral smokeless moist snuff product comprising:
- (a) an oral smokeless moist snuff composition comprising:
- disintegrated plant material,
- one or more salts selected from the group consisting of sodium chloride, sodium carbonate,
potassium carbonate, sodium sulphate, potassium sulphate, sodium lactate, potassium
lactate and any combination thereof, and
- water,
wherein the total amount of the one or more salts is within the range of from 15 %
by weight to 35 % by weight based on the total weight of water and total weight of
the one or more salts in the oral moist smokeless snuff composition,
wherein the total amount of moisture, said total amount of moisture being the total
amount of oven volatile ingredients, is within the range of from 35% by weight to
60% by weight based on the total weight of the oral smokeless moist snuff composition;
- (b) particles comprising a flavorant and a cellulose-derivatized polymer selected
from the group consisting of hydroxypropyl methylcellulose, hydroxypropyl cellulose,
methyl cellulose and any combination thereof,
wherein the amount of said particles is within the range of from about 1 % by weight
to about 25 % by weight based on the total weight of the oral smokeless moist snuff
product.
[0018] Further, there is provided a method for adding a flavorant to an oral smokeless moist
snuff product as described herein, said method comprising the steps of:
a) applying a flavorant onto at least part of one inside surface of a packaging container
for an oral smokeless moist snuff product,
b) placing the oral smokeless moist snuff product as described herein in the container,
and
c) closing the container.
DESCRIPTION
[0019] In accordance with the present disclosure, there is provided an oral smokeless moist
snuff product comprising:
- (a) an oral smokeless moist snuff composition as described herein, and
- (b) particles comprising a flavorant and a cellulose-derivatized polymer selected
from the group consisting of hydroxypropyl methylcellulose, hydroxypropyl cellulose,
methyl cellulose and any combination thereof, said particles being as defined herein.
[0020] Thus, the present disclosure provides an oral smokeless moist snuff product comprising:
- (a) an oral smokeless moist snuff composition comprising:
- disintegrated plant material,
- one or more salts selected from the group consisting of sodium chloride, sodium carbonate,
potassium carbonate, sodium sulphate, potassium sulphate, sodium lactate, potassium
lactate and any combination thereof, and
- water,
wherein the total amount of the one or more salts is within the range of from 15 %
by weight to 35% by weight based on the total weight of water and total weight of
the one or more salts in the oral moist smokeless snuff composition,
wherein the total amount of moisture, said total amount of moisture being the total
amount of oven volatile ingredients, is within the range of from 35 % by weight to
60 % by weight based on the total weight of the oral smokeless moist snuff composition;
- (b) particles comprising a flavorant and a cellulose-derivatized polymer selected
from the group consisting of hydroxypropyl methylcellulose, hydroxypropyl cellulose,
methyl cellulose and any combination thereof,
wherein the amount of said particles is within the range of from 1 % by weight to
25 % by weight based on the total weight of the oral smokeless moist snuff product.
[0021] The present disclosure is based on the finding that gelatine microcapsules containing
a flavorant when in admixture with an oral smokeless moist snuff composition soften
and/or disrupt upon storage even in the presence of a quite large amount of salt.
As a consequence, there is a leakage of flavorant into the oral smokeless moist snuff
composition containing tobacco or the non-tobacco plant fibres and this has a negative
impact on storage stability and/or the desired flavor profile of the product.
[0022] Producers, retailers and consumers of tobacco products desire tobacco products or
non-tobacco products with satisfactory storage stability at temperatures commonly
encountered or used. Frequently, oral smokeless moist snuff products are stored in
refrigerators or at room temperature making storage stability at temperatures within
the range of from about 5 to about 25 °C important. However, in colder or warmer places
storage stability at slightly lower or higher temperature may be desirable. For instance,
storage at about 0°C or about 30-45°C may be important. Common storage times range
from two weeks to six months.
[0023] Surprisingly, it has been found that the oral smokeless moist snuff product described
herein exhibits attractive flavor characteristics while at the same time providing
for satisfactory storage.
[0024] The flavor profile of the oral smokeless tobacco product described herein, such as
the oral smokeless moist snuff product, is such that flavorant release substantially
takes place after the oral smokeless tobacco product has been placed into a user's
mouth. Thus, there is little or no leakage of flavorant from the particles containing
a flavorant during storage and prior to placing the oral smokeless moist snuff product
into a user's mouth.
[0025] Further, when in the oral cavity of a user the flavorant release may take place during
an extended period of time such as about one hour. During the flavorant release, the
flavor intensity experienced by a user may increase over time so that the experienced
flavor intensity is higher at the end of usage than at the beginning. Alternatively,
during flavorant release a user may experience the flavor intensity to be substantially
constant.
[0026] As used herein, storage stability refers to the ability of a product to substantially
withstand alteration and/or degradation during storage. The product may be the oral
smokeless moist snuff product described herein and/or the particles containing a flavorant
described herein. For instance, the particles containing a flavorant are considered
to be storage stable when they substantially maintain their integrity during storage.
As an example, storage stability may refer to storage stability at about room temperature,
i.e. about 20-25 °C such as about 22 °C, during about three weeks. In a further example,
storage stability may refer to storage stability at about 5 °C during about twenty
weeks.
[0027] An oral smokeless moist snuff product may be considered to be storage stable when
at least about 75 %, such as about 80%, about 85%, about 90%, about 95% or about 100%,
of the total flavor of the flavorant particles remains encapsulated. The total flavour
intends the sum of the flavor of the particles containing a flavorant and the flavor
contained in the oral smokeless moist snuff composition. The total flavor may be determined
as described in the experimental section of this document.
[0028] While not wishing to be bound by any specific theory, it is believed that the one
or more salts selected from the group consisting of sodium chloride, sodium carbonate,
potassium carbonate, sodium sulphate, potassium sulphate, sodium lactate and potassium
lactate and any combinations thereof act by lowering the cloud point of the cellulose-derivatized
polymer enclosing the flavorant. In this document, the polymer cloud point defines
the temperature above which the cellulose-derivatized polymer is insoluble, and below
which it is soluble. By lowering the cloud point temperature, the particles containing
a flavorant such as the microcapsules or granules maintain their integrity and thus
their storage stability at a desired temperature thereby preventing or minimizing
flavorant leakage during storage and prior to use. For instance, it may be desired
that the particles such as the microcapsules or granules maintain their integrity
at a temperature from about 0°C to about 50°C, such as from about 5 °C to about 45°C
or at body temperature (i.e. about 37°C). However, when the concentration of the one
or more salts is lowered the particles such as the microcapsules or granules soften
and/or disintegrate thereby releasing the encapsulated flavorant. Therefore, when
the oral smokeless moist snuff product described herein is placed in a user's mouth
saliva excretion lowers the salt concentration leading to microcapsule softening and
disintegration followed by extended flavorant release. This is in contrast to, for
example, thermosensitive microcapsules in which a mere temperature change results
in capsule disintegration.
[0029] The salting out of polymers leading to polymer cloud point lowering is known in other
technical fields. However, in oral smokeless moist snuff products the tobacco or the
non-tobacco plant fibres contain a large number of components which may influence
the polymer cloud point. Further, other components that are frequently present in
oral smokeless moist snuff may also have an impact on the cellulose-derivatized polymer
cloud point. It is therefore a complex task to provide an oral smokeless moist snuff
product wherein extended flavor release substantially takes place after having placed
the product into a user's mouth.
[0030] The disintegrated plant material may be disintegrated tobacco or disintegrated non-tobacco
plant fibres as described herein.
[0031] As used herein, the term "disintegrate(d)" is understood to mean cut, ground and/or
shredded.
[0032] The disintegrated plant material may be shredded. In a further example, the disintegrated
plant material may be finely disintegrated, i.e. it has an average particle size of
less than 2 mm. The particles of the finely disintegrated plant material, such as
finely disintegrated tobacco material, may be sized to pass through a screen of about
10 (US) mesh, i.e. sieve size 2.0 mm, or 18 (US) mesh, i.e. sieve size 1.0 mm.
[0033] In this document, the term "snuff" used in the context of oral smokeless moist snuff
composition and/or oral smokeless moist snuff product may intend fermented snuff and/or
pasteurized snuff. Thus, the snuff may be American-type moist snuff and/or Scandinavian-type
moist snuff (i.e. snus).
[0034] An oral smokeless moist tobacco composition is an oral smokeless moist snuff composition
wherein the disintegrated plant material comprises or consists of tobacco. Addition
of particles containing a flavorant as described herein to the oral smokeless moist
tobacco composition provides an oral smokeless moist tobacco product. The tobacco
may be mixed with non-tobacco fibres as decribed herein.
[0035] An oral smokeless moist non-tobacco composition is an oral smokeless moist snuff
composition wherein the disintegrated plant material comprises or consists of non-tobacco
fibres. Addition of particles containing a flavorant as described herein to the oral
smokeless moist non-tobacco composition provides an oral smokeless non-tobacco product.
As an example, the oral smokeless moist non-tobacco composition and/or the oral smokeless
non-tobacco product does not comprise tobacco material such as disintegrated tobacco.
[0036] The tobacco may be any part, e.g. leaves or stems, of any member of the genus Nicotiana.
The tobacco may be whole or disintegrated, i.e. shredded, cut, ground, cured. Further,
the tobacco may be aged, fermented or treated otherwise. The tobacco may include types
of material such as flue-cured tobacco, burley tobacco, oriental tobacco, Maryland
tobacco, dark tobacco, dark-fired tobacco, dark air cured or light air cured and Rustica
tobaccos as well as other rare or specialty tobaccos. The tobacco of the present disclosure
may contain a single type of tobacco or different types of tobacco. The tobacco can
have the form of processed tobacco parts or pieces, cured and aged tobacco in substantially
natural lamina or stem form, a tobacco extract, extracted tobacco pulp or a mixture
of the foregoing. The tobacco may be mixed together with non-tobacco fibres. The tobacco
contains salt such as sodium chloride and/or potassium chloride. The total chloride
content, i.e. the chloride originating from chloride salts such as sodium and potassium
chloride, may be within the range of from about 3 to about 8 % by weight such as from
about 3 to about 6 % by weight based on the weight of the tobacco flour, said tobacco
flour may contain about 7 % by weight of water. The chloride content of the disintegrated
tobacco or the disintegrated non-tobacco plant material may be about 3 % by weight
or about 4 % by weight based on the weight of the tobacco flour, said tobacco flour
may contain about 7 % by weight of water.
[0037] The non-tobacco plant fibres may be fibres from non-tobacco plants such as maize
fibers, oat fibers, tomato fibers, barley fibers, rye fibers, sugar beet fibers, buck
wheat fibers, potato fibers, cellulose fibers, apple fibers, cocoa fibers, bamboo
fibers and citrus fibers. The non-tobacco plant fibres may be whole or disintegrated,
i.e. shredded, cut, ground. Further, the non-tobacco plant fibres may be cured, aged,
fermented or treated otherwise. The amount of non-tobacco plant fibers, such as bamboo
fibers, in the smokeless tobacco composition may be within the range of from about
1 to about 60% w/w or from about 2 to about 20% w/w based on dry weight of the smokeless
tobacco composition. Micro Crystalline Cellulose may also be used as an alternative.
[0038] The non-tobacco fibers may have an average length-to-width ratio equal to or greater
than 3.5:1 and equal to or lower than 100:1. The non-tobacco plant fibers may originate
from bamboo. The non-tobacco fibers may have an average length-to-width ratio equal
to or lower than 25:1. The non-tobacco fibers may have an average length-to-width
ratio equal to or greater than 6:1. The non-tobacco fibers may have an average length-to-width
ratio equal to or greater than 10:1. The non-tobacco fibers may have an average length-
to-width ratio equal to or greater than 15:1.
[0039] The oral smokeless moist snuff product described herein may be provided in particulate
form, as a loose powder, or be portion-packaged in a pouch. The pouch may be made
of a water-permeable material so that extraction of components such as nicotine and/or
flavorant may easily take place when the product is placed in a user's mouth.
[0040] The encapsulation of the flavorant in the microcapsule or granule may be encapsulation
of the flavorant by a shell such as a coating. Alternatively or additionally, the
flavorant encapsulation may be that the flavorant is contained in a matrix. For instance,
the flavorant may be dispersed within a matrix. The matrix may be enclosed by a shell
or coating. The shell and/or the matrix may comprise or consist of a cellulose-derivatized
polymer selected from the group consisting of hydroxypropyl methylcellulose, hydroxypropyl
cellulose, methyl cellulose and any combinations thereof. As an example, there is
provided an oral smokeless moist snuff product as described herein, wherein the flavorant
is encapsulated by a coating comprising a cellulose-derivatized polymer as described
herein. The cellulose-derivatized polymer may be hydroxypropyl methylcellulose.
[0041] The cellulose-derivatized polymer described herein may be mixed with further ingredients.
For instance, the cellulose-derivatized polymer may be mixed with talcum powder. As
an example, hydroxypropylmethyl cellulose may be mixed with talcum powder.
[0042] In a further example, the microcapsule or granule flavorant of the oral smokeless
moist snuff product described herein is encapsulated by an inner coating and an outer
coating. The inner coating may comprise or consist of gelatine. The outer coating
may comprise or consist of a cellulose-derivatized polymer selected from the group
consisting of hydroxypropyl methylcellulose, hydroxypropyl cellulose, methyl cellulose
and any combinations thereof. As an example, the outer coating may comprise or consist
of hydroxypropyl methylcellulose. In a further example, the inner coating comprises
or consists of gelatine, and the outer coating comprises or consists of hydroxypropyl
methylcellulose optionally in combination with talcum powder.
[0043] The outer coating is salt-sensitive so that it substantially remains in a solid state
in the presence of a salt selected from the group consisting of sodium chloride, sodium
carbonate, potassium carbonate, sodium sulphate, potassium sulphate, sodium lactate
and potassium lactate and any combinations thereof in the amounts indicated herein.
When the salt concentration is lowered, such as upon saliva excretion in a user's
mouth, the outer coating softens and/or dissolves so that the gelatine inner coating
is exposed. Since gelatine will soften and/or dissolve upon contact with the moisture
present in the oral smokeless moist snuff product the flavorant will be released.
In order to prevent or minimize flavorant release during storage and prior to being
placed in a user's mouth, the outer coating should cover most of the inner coating.
Advantageously, the outer coating should be free or substantially free from cracks.
[0044] The oral smokeless moist snuff product described herein comprises one or more salts
selected from the group consisting of sodium chloride, sodium carbonate, potassium
carbonate, sodium sulphate, potassium sulphate, sodium lactate, potassium lactate
and any combinations thereof. The sodium chloride may be replaced entirely or partly
with potassium chloride.
[0045] It will be appreciated that when the one or more salts is a combination of different
salts each salts may be present in an amount sufficient to contribute to cellulose-derivatized
polymer cloud point lowering in the oral smokeless moist snuff product.
[0046] As an example, the one or more salts of the oral smokeless moist snuff product described
herein may comprise or consist of sodium chloride, sodium carbonate and potassium
sulphate.
[0047] In a further example, the one or more salts of the oral smokeless moist snuff product
described herein may comprise or consist of sodium sulphate and/or potassium sulphate
and one or more salts selected from the group consisting of sodium chloride, sodium
carbonate, potassium carbonate and any combination thereof.
[0048] In still a further example, the one or more salts of the oral smokeless moist snuff
product described herein comprises sodium carbonate, sodium chloride and optionally
one or more salts selected from the group consisting of potassium carbonate, sodium
sulphate, potassium sulphate, sodium lactate, potassium lactate and any combination
thereof.
[0049] Further, the sodium chloride may be replaced entirely or partly with sodium sulphate
or potassium sulphate. Replacing the sodium chloride with sodium sulphate and/or potassium
sulphate may affect the flavour profile of the product, which may be desirable to
meet the demands of certain users. Unexpectedly, the inventors of the present disclosure
have found that sodium chloride may be exchanged for sodium sulphate and/or potassium
sulphate to at least some extent without affecting the cloud point of the cellulose-derivatized
polymer of the particles containing a flavorant.
[0050] The one or more salts may be mixed with the disintegrated plant material such as
tobacco or with the non-tobacco plant fibres. Additionally, the one or more salts
may be contained in the microcapsules. As an example, the one or more salts may be
contained in the microcapsule or granule shell or the microcapsule or granule matrix.
In a further example, the one or more salts is mixed with the disintegrated plant
material such as tobacco or non-tobacco plant fibres and also contained in the microcapsules
or granules.
[0051] As described herein, the one or more salts selected from the group consisting of
sodium chloride, sodium carbonate, potassium carbonate, sodium sulphate, potassium
sulphate, sodium lactate, potassium lactate and any combinations thereof are believed
to have a so-called salting in effect whereby the integrity of the particles containing
a flavorant such as microcapsules or granules is maintained until the salt concentration
is lowered. Further, it will be appreciated that the one or more salts of the oral
smokeless moist snuff composition and/or the oral smokeless moist snuff product includes
the sodium chloride and/or the potassium chloride occurring naturally in the disintegrated
plant material. Thus, the one or more salts of the oral smokeless moist snuff composition
and/or the oral smokeless moist snuff product includes added salts as well as sodium
chloride and/or potassium chloride occurring naturally in the disintegrated plant
material.
[0052] It will be appreciated that the one or more salts described herein includes salts
commonly used in snuff, such as sodium chloride, as well as salts used as pH adjusters,
such as sodium carbonate. Sodium chloride provides a salty taste and/or antimicrobial
activity and may also influence the cellulose-derivatized polymer cloud point. Sodium
carbonate provides pH adjustment and may also influence the cellulose-derivatized
polymer cloud point. Thus, in addition to lowering the cloud point of the cellulose-derivatized
polymer the one or more salts may provide taste, pH adjustment, antimicrobial activity
etc.
[0053] The one or more salts may be sodium lactate and/or potassium lactate. This may be
advantageous since sodium lactate and/or potassium lactate have a neutral taste, an
antibacterial activity and are also believed to have a lower impact on a cellulose-derivatized
polymer than, for instance, sodium chloride. As an example, all or at least part of
the sodium chloride may be exchanged for sodium lactate and/or potassium lactate.
[0054] In a further example, the one or more salts may be selected from the group consisting
of sodium chloride, potassium carbonate, potassium sulphate and any combinations thereof.
In a further example, the one or more salts may comprise sodium carbonate and a salt
selected from the group consisting of potassium carbonate, sodium sulphate, potassium
sulphate, sodium lactate, potassium lactate and any combination thereof.
[0055] In still a further example, the one or more salts may comprise potassium carbonate
and a salt selected from the group consisting of sodium carbonate, sodium sulphate,
potassium sulphate, sodium lactate, potassium lactate and any combination thereof.
[0056] Further, the one or more salts of the oral smokeless moist snuff product described
herein may comprise or consist of sodium chloride, sodium carbonate and potassium
sulphate. The ratio sodium chloride: sodium carbonate: potassium sulphate may be about
6:3:1 or about 7:2:1. It will be appreciated that the potassium sulphate may be replaced
entirely or partly with sodium chloride and/or potassium chloride. Thus, the one or
more salts of the oral smokeless moist snuff product described herein may comprise
or consist of sodium carbonate and sodium chloride and/or potassium chloride.
[0057] Further, the one or more salts of the oral smokeless moist snuff product described
herein may comprise or consist of sodium chloride, sodium carbonate and optionally
one or more salts selected from the group consisting of potassium carbonate, sodium
sulphate, potassium sulphate, sodium lactate, potassium lactate and any combinations
thereof. The one or more salts of the oral smokeless moist snuff product described
herein may comprise or consist of sodium sulphate and/or potassium sulphate and/or
one or more salts selected from the group consisting of sodium chloride, sodium carbonate,
potassium carbonate and any combinations thereof.
[0058] The total amount of the one or more salts of the oral smokeless moist snuff composition
and/or the oral smokeless moist snuff product prepared for the consumer may be estimated
using any method known in the art to a skilled person. For instance, the total amount
of the one or more salts may be estimated or indicated based on the measurement of
ionic strength or conductivity.
[0059] The amount of the one or more salts will depend on the total amount of moisture of
the oral smokeless moist snuff composition. Generally, to maintain flavorant particle
integrity in the oral smokeless moist snuff product the amount of the one or more
salts will have to be increased when the total amount of moisture of the oral smokeless
moist snuff composition is raised. The inventors of the present disclosure have found
that for a total amount of moisture within the range of from 35% by weight to 60%
by weight based on the total weight of the oral smokeless moist snuff composition,
the total amount of the one or more salts should be within the range of 15 % by weight
to 35 % by weight based on the total weight of water and total weight of the one or
more salts in the oral smokeless moist snuff composition. The amount of particles
containing a flavorant as described herein is within the range of from 1 % by weight
to 25 % by weight based on the total weight of the oral smokeless moist snuff product.
For instance, the amount of particles containing a flavorant may be within the range
of from about 5 % by weight to 25 % by weight, from about 5% by weight to about 20
% by weight, from about 5 % by weight to about 15 % by weight, from about 5 % by weight
to about 10 % by weight or from about 10 % by weight to about 20 % by weight based
on the total weight of the oral smokeless moist snuff product. In a further example,
the amount of particles containing a flavorant may be about 5 % by weight, about 10
% by weight, about 15 % by weight or about 20 % by weight based on the total weight
of the oral smokeless moist snuff product.
[0060] As an example, in the oral smokeless moist snuff composition of the oral smokeless
moist snuff product described herein the total amount of the one or more salts is
within the range of from 15 % by weight to 35 % by weight, from about 15 % by weight
to about 25 % by weight or from about 20 % by weight to about 25 % by weight, based
on the total weight of water and the total weight of the one or more salts of the
oral smokeless moist snuff composition, and the total amount of moisture may be within
the range of from about 45 % by weight to 60 % by weight based on the total weight
of the oral smokeless moist snuff composition. The amount of particles containing
a flavorant as described herein is within the range of from 1 % by weight to 25 %
by weight based on the total weight of the oral smokeless moist snuff product. For

[0067] In a further example, there is provided an oral smokeless moist snuff product comprising:
- (a) an oral smokeless moist snuff composition comprising:
- disintegrated plant material,
- sodium chloride, sodium carbonate and optionally potassium sulphate, and
- water,
wherein the total amount of the one or more salts is about 25 % by weight based on
the total weight of water and total weight of the one or more salts in the oral moist
smokeless snuff composition,
wherein the total amount of moisture is about 46 % by weight based on the total weight
of the oral smokeless moist snuff composition;
- (b) particles comprising a flavorant and hydroxypropyl methylcellulose,
wherein the amount of said particles is about 10 % by weight based on the total weight

[0068] Additionally, the oral smokeless moist snuff product may comprise from about 1 to
about 5 % by weight, such as from about 2 to about 4 % by weight, based on the dry
weight of the oral smokeless moist snuff composition, of a humectant selected from
the group consisting of propylene glycol and glycerol. The oral smokeless moist snuff
product described herein may comprise no or substantially no humectant. It will be
appreciated that the humectant should be selected in such a way and/or in an amount
that it influences the cloud point of the cellulose-derivatized polymer to only a
small extent or not at all. For instance, glycerol will have only a small impact on
the cellulose polymer cloud point whereas propylene glycol will have a larger impact.
Therefore, in case propylene glycol is used the amount should be adjusted to avoid
a too large impact on the cellulose cloud point. For instance, propylene glycol in
an amount of about 2 to about 4 % by weight, such as from about 0.5 to about 2 % by
weight, such as from about 1 to about 3 % by weight, such as from about 1 to about
2 % by weight, based on the dry weight of the oral smokeless moist snuff composition,
may be added to the oral smokeless moist snuff product described herein. The impact
of the humectant on the cellulose-derivatized polymer cloud point may at least to
some extent be compensated for by increasing the amount of the one or more salts.
The humectant of the oral smokeless moist snuff product described herein may contain
a humectant comprising or consisting of glycerol.
[0069] As used herein, the term "total amount of moisture" refers to the total amount of
oven volatile ingredients, such as water and other oven volatiles (e.g. propylene
glycol, ethanol etc.) in the preparation, composition or product referred to. The
total amount of moisture is given herein as percent by weight (wt%) of the total weight
of the preparation, composition or product referred to. The total amount of moisture
as referred to herein may be determined by using the LOD method disclosed in the Examples
in which the oven volatile content at a temperature of about 105°C is determined.
Thus, the total amount of moisture may refer to the total amount of oven volatiles
measured of a temperature at about 105°C, such as measured with an LOD method. In
this document, the expressions "total amount of moisture", "moisture content" and
"moisture level" are used interchangeably.
[0070] The total amount of moisture of the oral smokeless moist snuff composition ranges
from 35 % by weight to 60 % by weight such as from about 40 % by weight to about 60
% by weight, from about 45 % by weight to about 60 % by weight, from about 45 % by
weight to about 55 % by weight, from about 50 % by weight to about 55 % by weight,
from about 50 % by weight to about 60 % by weight or from about 55 % by weight to
60 % by weight. For instance, the total amount of moisture of the oral smokeless moist
snuff composition may be 35 % by weight, about 40% by weight, about 45 % by weight,
about 46 % by weight, about 55 % by weight or 60 % by weight.

[0078] The particles described herein may be microparticles, such as microcapsules or granules
as described herein. The particles may or may not contain a carrier.
[0079] The particles such as microcapsules or granules of the present disclosure contain
a flavorant. As used herein, the terms "flavorant", "flavor" "flavoring agent" or
the like denote a substance used to influence the aroma and/or taste of the oral smokeless
moist snuff product.
[0080] In this document, whenever the particles are described with respect to microcapsules
it will be appreciated that the term microcapsules may be exchanged for granules,
capsules, microparticles etc.
[0081] The flavorant may be a single flavor or a combination of flavorants/flavors. The
flavorant may be in solid or liquid form. The liquid form may be a liquid composition
such an oil. For instance, the flavorant may be an essential oil, a compounded flavoring
and/or extracts. Further, the flavorant may be natural or synthetic. Examples of flavorants

the flavor may contain tobacco flavorant. Alternatively, the flavorant may be a non-tobacco
flavorant.
[0082] As an example, the flavorant may be a solid encapsulated by a shell such as a coating
comprising, for instance, hydroxypropyl methylcellulose, to provide a granule or microcapsule.
In a further example, the flavorant may be dispersed within a matrix and optionally
encapsulated by a shell such as a coating comprising, for instance, hydroxypropyl
methylcellulose, to provide a granule or microcapsule.
[0083] The particles containing a flavorant such as microcapsules may be a mixture of microcapsules
containing different flavorants. For instance, 50% of the microcapsules may contain
a first flavorant and the remaining 50% may contain a second flavorant different from
the first flavorant.
[0084] When the particles contain an inner coating and/or an outer coating, then the inner
coating and/or the outer coating of the microcapsules may or may not contain a flavor.
As an example, the inner and/or the outer coating contain no flavor. In a further
example, the inner and/or outer contain a non-tobacco flavor.
[0085] The total weight of the particles containing a flavorant such as microcapsules contained
within the oral smokeless moist snuff product may vary. The amount of said particles
is within the range of from 1 % by weight to 25 % by weight, such as from about 5
% by weight to 25 % by weight or from about 5 % by weight to about 10 % by weight,
based on the total weight of the oral smokeless moist snuff product. As an example,
the amount of said particles may be about 5 % by weight, about 10 % by weight, about
15 % by weight or about 20 % by weight. In a further example, the amount of said particles
may be about 10 % by weight.
[0086] The particles , such as microcapsules or granules, containing a flavorant may be
mixed with an oral smokeless moist snuff composition to provide the oral smokeless
moist snuff product. For instance, the particles containing a flavorant may be added
to the oral smokeless moist snuff composition or vice versa. Alternatively, the particles
containing a flavorant and the components of the oral smokeless moist snuff composition
may be mixed in any order to provide the oral smokeless moist snuff product. If desired,
a single particle such as a capsule or granule having a size larger than that of the
microcapsules or granules may be used in addition to or instead of a plurality of
microcapsules and/or granules. The single capsule may contain a flavorant that is
the same as or different from that of the microcapsules and/or granules.
[0087] The shape of the particles, such as microcapsules or granules, may vary, but typically
the microcapsules or granules have a substantially spherical shape. Alternatively,
the microcapsules or granules may have other types of shapes such as rectilinear,
oblong, elliptical or oval shapes.
[0088] The particles containing a flavorant such as microcapsules or granules may be uniform
or varied in size. The microcapsule or granule diameter may be from 1 to 5 mm, such
as from 1 to 4 mm or from 1 to 3 mm or from 300 micrometers to 1 mm. Further, the
microcapsules or granules may be spherical and have a diameter equal to or less than
about 300 micrometers, such as from 100-300 micrometers, such as from 100-200 micrometers,
or from 1 to 40 micrometers or from 1 to 20 micrometers. As an example, the microcapsule
or granule diameter may be about 1 mm. In some oral smokeless moist snuff products
it may be desired to include microcapsules or granules of substantially uniform size,
whereas in other oral smokeless moist snuff products it may be desired to include
microcapsules or granules with varying size.
[0089] If desired, particles such as microcapsules of different sizes and types may be included
in the oral smokeless moist snuff products to provide for a desired flavor release
profile. For example, a first flavorant may be released from a first set of microcapsules
or granules, and a second flavorant may be released from a second set of microcapsules
or granules. The release of the first flavorant may take place prior to, at the same
time as or after release of the second flavorant.
[0090] The particles containing a flavorant described herein may be dyed. The dye may be
provided by a color additive approved for use in food. By providing at least part
of the particles as dyed particles the consumer may perceive the oral smokeless moist
snuff product as more interesting and/or appealing.
[0091] The crush strength of the microcapsules disclosed herein is sufficient to allow for
normal handling and storage without significant premature or undesirable breakage.
[0092] If desired, a non-encapsulated flavorant may be mixed with the disintegrated plant
material such as tobacco or non-tobacco plant fibres of the oral smokeless moist snuff
product described herein. For instance, the flavorant may be added by spraying it
onto the tobacco or the non-tobacco plant fibres. The flavorant may be sprayed directly
onto loose tobacco and/or non-tobacco fibres or onto pouches containing tobacco and/or
non-tobacco fibres. In this way, a user placing the oral smokeless moist snuff product
described herein into his or her mouth will immediately experience the flavorant mixed
with the tobacco or non-tobacco plant fibres and then gradually also experience the
flavorant released from the microcapsules. The non-encapsulated flavorant may be the
same or different from that contained in the particles containing a flavorant such
as microcapsules or granules. In this way, a consumer may perceive the taste of the
oral smokeless moist snuff product to evolve and/or change overtime.
[0093] Alternatively or additionally, a non-encapsulated flavorant may be added to the oral
smokeless moist snuff product described herein by coating at least part of one inside
surface, such as an inside lid or bottom surface, of a container with the flavorant,
adding the oral smokeless moist snuff product to the container and closing of the
container. The container is a packaging container for an oral smokeless moist snuff
product. When the container is closed, the flavorant applied to the at least part
of one inside surface of the container will flavorize the oral smokeless moist snuff
product. Accordingly, there is provided a method for adding a flavorant to an oral
smokeless moist snuff product as described herein, said method comprising the steps
of:
- a) applying a flavorant onto at least part of one inside surface of a packaging container
for an oral smokeless moist snuff product,

BRIEF DESCRIPTION OF THE DRAWINGS
[0115] Figure 1 shows a graph indicating flavor intensity experienced by eleven test persons
during a time period of 60 minutes.
[0116] The disclosure is illustrated by the following non-limitative Examples.
EXAMPLES
[0117] The following equipment and general procedures were used in the Examples below.
General
[0118] Headspace screw top vials (20 ml) were purchased from ThermoScientific. Petroleum
ether Suprasolv was purchased from VWR. Samples were shaken on an incubation orbital
shaker, professional 3500, purchased from VWR. Analyses were performed on an Agilent
5890/5972/7673 GCMS-system, operating in full scan mode. GC column was an Agilent
Innowax (60 m x 0.25 mm x 0.25 um).
Measurements
[0119] Snus samples were extracted with two different extraction methods, one for total
flavor and one for free flavor. In this document, total flavor intends the total analyzed
amount of flavor in the product consisting of moist snus and microcapsules. Thus,
the total flavor intends the sum of the flavor of the microcapsules and the flavor
contained in the moist snus. In this document, free flavor intends the analyzed amount
of flavor in the moist snus. Thus, the free flavor intends the flavor contained in
the moist snus, excluding the flavor of the non-disintegrated microcapsules. Unless
otherwise indicated, in all Examples the flavor is a mixture of peppermint and menthol.
After extraction a GC/MS method (the same method for both extractions) was used to
estimate the amount of flavor in the extracts. This was a semi-quantitative method
for menthol, which served as a marker for all flavor compounds. The area of menthol
was integrated and area units were compared between samples.
Extraction of total flavor
[0120] For each replicate 0.5-1 g of snus or one pouch (cut in two pieces) was put into
a headspace vial. 5 ml of tap water was added. The samples were shaken for 5 min at
ambient temperature (360 rpm). Thereafter 5 ml of petroleum ether was added before
samples were shaken for 60 minutes at 50 °C (360 rpm). After cooling samples were
put on GC-vials and analyzed with GC/MS.
Extraction of free flavor
[0121] For each replicate 0.5-1 g of snus or one pouch (cut in two pieces) was put in to
a headspace vial. 5 ml of petroleum ether was added. The samples were shaken for 5
min at ambient temperature (360 rpm). After 5 minutes of sedimentation samples were
put on GC-vials and analyzed with GC/MS. The area as measured by GC/MS is indicated
in Table 3.
Tobacco
[0122] In the examples below, grinded and heated moist tobacco refers to tobacco that has
been prepared as follows. The tobacco was grinded and pasteurized, and the moisture
content was adjusted with water to about 35 wt%. The chloride content of the tobacco
flour prior to grinding and pasteurization, i.e. the sum of chloride from NaCl and
KCI, was about 3. wt% based on the weight of the tobacco flour. The total amount of
moisture of the tobacco flour was 7 wt%.
Moist snus versus moist snus product
[0123] In the examples below, "moist snus" refers to a mixture of grinded and heated moist
tobacco, sodium carbonate, potassium sulphate, sodium chloride, ethanol and water.
In some examples the potassium sulphate was excluded.
[0124] Further, in the examples below "moist snus product" refers to the mixture resulting
from adding microcapsules to the moist snus, i.e. a mixture of microcapsules, grinded
and heated moist tobacco, sodium carbonate, potassium sulphate, sodium chloride, ethanol
and water. In some examples the potassium sulphate was excluded.
LOD method
[0125] In all the following examples, the moisture content of each of the tobacco material
and the non-tobacco plant fibers, if present, was determined by using a method based
on
literature references Federal Register/ vol.74, no. 4/712-719/Wednesday, January 7,
2009/Notices, "Total moisture determination" and AOAC (Association of Official Analytical Chemics),
Official Methods of Analysis 966.02: "Moisture in Tobacco" (1990), Fifth Edition,
K. Helrich (ed). In this method, the oven volatile (OV) content of the tobacco material and the
non-tobacco plant fibers, if present, is measured as described hereinafter.
[0126] The moisture content (i.e. the oven volatile content) of each of the tobacco material
and the non-tobacco plant fibers, if present, was determined gravimetrically by taking
2.5±0.25 g sample and weighing the sample before evaporation of moisture and after
evaporation of moisture. Mettler Toledo's Moisture Analyzer HB43, a balance with halogen
heating technology, was used (instead of an oven and a balance as in the mentioned
literature references). The sample was heated to 105 °C (instead of 99.5±0.5 °C as
in the mentioned literature references). The measurement was stopped when the weight
change was less than 1 mg during a 90 seconds time period. The moisture content (i.e.
oven volatile content) as weight percent of the original weight of the sample is then
calculated automatically by the Moisture Analyzer HB43.
[0127] As mentioned herein above, the content of oven volatiles other than water (i.e. nonaqueous
oven volatiles) in tobacco flour, is normally less than 1% by weight. Therefore the
moisture content of tobacco material as measured using the herein described method
substantially corresponds to the actual water content of the tobacco material. In
the examples, the given water content of the initial tobacco preparations is the calculated
sum of oven volatiles content of the tobacco material and the non-tobacco plant fibers
if present, as measured by the above disclosed method, and, where applicable, the
amount of water added to the tobacco material in the process.
EXAMPLE 1
[0128] Microcapsules were formed in the following manner.
[0129] 40,0 g of hydroxypropyl methylcellulose, type 2910, viscosity 3 mPa*s (SheffCel 60HD3,
purchased from Kerry) was dissolved in 360 g of purified water resulting in a 400
g weight solution.
[0130] For the coating process a fluid bed Mini-Glatt (from Glatt GmbH, Binzen) with bottom
spray coating (Wurster) was used. The spray nozzle was 0.5 mm in diameter. The bottom
filter was 100 µm, mounted on a bottom plate with diameter 7.5 cm.
[0131] 90 g of Millicaps 1000 E_1413279 (from V. MANE FILS, France) was charged in the fluid
bed. The Millicaps were substantially gelatin microcapsules containing a liquid peppermint/menthol
flavorant. 230 g of the above prepared solution was sprayed on to the Millicaps 1000
E_1413279. Settings for the process were as indicated in Table 1.

[0132] The formed microcapsules were then sieved through a sieve with a mesh size of 2 mm
and the upper fraction was removed.
[0133] The moist snus was prepared by mixing sodium carbonate, potassium sulphate, sodium
chloride, ethanol and water with grinded and heated moist tobacco. The amounts were
as indicated in Table 2 below. Thus, the moist snus of the moist snus product consisted
of grinded and heated moist tobacco prepared as described above, sodium carbonate,
potassium sulphate, sodium chloride, ethanol and water in amounts as indicated in
Table 2.
[0134] The above manufactured microcapsules were mixed with the moist snus, said moist snus
having a total amount of moisture of about 46 % by weight based on the moist snus,
to provide a moist snus product. The composition of the moist snus product is indicated
in Table 2.
[0135] The moist snus product was packaged in pouches, each pouch having with a weight of
about 0.8 g. The pouches were stored in a sealed plastic bag for two weeks at room
temperature.

[0137] Analysis regarding content of menthol was performed in two batches, one for free
flavor and one for total flavor. As indicated in Table 3, the free flavor content
of the moist snuff was only 4.6% after storage 2 weeks in room temperature. It can
be concluded that the HPMC coated gelatin microcapsules containing the liquid flavorant
did not release the flavorant to any significant extent. Thus, the HPMC coated gelatin
microcapsules containing the liquid flavorant are substantially storage stable in
the moist snus.
EXAMPLE 2
[0138] Pouches consisting of the moist snus and microcapsules, said pouches being manufactured
as in Example 1, were evaluated regarding flavor release function as follows. The
pouches were stored for two weeks in a sealed plastic bag prior to use.
[0139] 11 test persons used the pouches for 60 minutes. The pouch was put between the gum
and the upper lip and the pouch was fixed in that position during the whole test period.
After 60 minutes of use, the total amount of menthol left in the used pouches were
analyzed and compared to the total amount of analyzed menthol in unused pouches. The
test persons used two pouches each. The pouches were analyzed using GC/MS according
to the method described above. The results are indicated in Table 4 (Total flavor
of unused pouches) and Table 5 (Total flavor of used pouches). The microcapsule flavorant
was peppermint and menthol. The analysis was performed with respect to menthol.

[0140] The amount of extracted menthol (%) was then calculated as:
Extracted menthol (%) = (Average area unused pouches - Average area used pouches)
/ (Average area unused pouches). As indicated above, the average area unused pouches
is 881118.3, and the average area used pouches is 809610.5. It follows that (881118.3
- 809610.5) / (881118.3) = 8.1%. Thus, release of menthol from the HPMC coated gelatin
microcapsules took place when the test persons used the pouches as indicated above.
The test persons were also asked to evaluate their experience of flavorization. The
flavor intensity was measured on a scale from 0 to 5, where 0 indicates no experience
of flavor and 5 a high experience of flavor intensity. The sensory evaluation was
made five and 60 minutes after having placed the oral moist snuff product in the mouth.
The mean flavor intensity was calculated for the 11 test persons at 5 and 60 minutes
respectively, and the result is shown in Figure 1. It can be concluded that the experienced
flavor intensity increased over time.
EXAMPLE 3
[0141] Millicaps 1000 E_1413279 were purchased from V. MANE FILS, France. The Millicaps
were substantially gelatin microcapsules containing a liquid menthol flavorant.
[0142] Moist snus was prepared by mixing sodium carbonate, potassium sulphate, sodium chloride,
ethanol and water with grinded and heated moist tobacco. The amounts were as indicated
in Table 6 below. Thus, the moist snus of the moist snus product consisted of grinded
and heated moist tobacco, sodium carbonate, potassium sulphate, sodium chloride, ethanol
and water in amounts as indicated in Table 6.
[0143] The Millicaps were mixed with the moist snus, said moist snus having a total amount
of moisture of about 46 % by weight based on said moist snus, to provide a moist snus
product. The composition of the moist snus product was as indicated in Table 6.
[0144] The moist snus product was packaged in pouches, each pouch having a weight of about
0.8 g. 10 pouches were prepared. The pouches were stored for two weeks at room temperature
in a sealed plastic bag.

[0145] After storage for two weeks at room temperature the pouches consisting of moist snus
and Millicaps 1000 E_1413279 were analyzed regarding content of menthol according
to the GC/MS method described in Example 1. One batch was for free flavor and one
was batch for total flavor. As indicated in Table 7, 83 % of the total amount of menthol
was found in the moist snus after storage 2 weeks in room temperature.

As indicated above, the average area free flavor is 606231, and the average area total
flavor is 730893. It follows that the free flavor is 606231/ 730893=83%. It can be
concluded that the gelatin microcapsules released the menthol flavorant during storage.
Thus, the gelatin microcapsules do not exhibit storage stability in the moist snus.
Further, it can be concluded that addition of the salts in the amounts indicated in
Table 6 did not prevent release of the menthol flavorant from the gelatin microcapsules. |
EXAMPLE 4
[0146] Two samples were prepared as follows.
Sample 1
[0147] Moist snus was prepared by mixing sodium carbonate, potassium sulphate, sodium chloride,
ethanol and water with grinded and heated moist tobacco. The amounts were as indicated
in Table 8 below. The total amount of moisture of the moist snus was about 45 % by
weight based on said moist snus.
[0148] 3.0 g of the moist snus and 0.15 g of HPMC coated gelatin microcapsules, said microcapsules
being prepared as in Example 1, were mixed to provide the moist snus product indicated
in Table 8.
[0149] The mixture was then stored in a sealed test tube in room temperature for two weeks.
The composition of the moist snus product was as indicated in Table 8.

[0150] Commercially available pouches consisting of snus "Skruf fresh tranbar xtra stark
white slim" (Skruf Snus AB) were chopped to provide 3.0 g snus with a moisture content
of about 43% which was then mixed with 0.15 g of the HPMC coated gelatin microcapsules
prepared in Example 1. The mixture was then stored in a sealed test tube in room temperature
for two weeks.
[0151] Samples 1 and 2 were analyzed regarding content of menthol according to the method
described in Example 1. The results are indicated in Table 9.

[0152] As can be seen from Table 9, the free flavor content of the stored Sample 1 was only
3% indicating that substantially no flavor release from the microcapsules had taken
place. In contrast, the free flavor content of the stored Sample 2 was 42% indicating
a significant flavor release from the microcapsules.
[0153] It can be concluded that the HPMC coated gelatin microcapsules were substantially
stable upon storage in the moist snus of Sample 1. In comparison with Sample 1, the
storage stability of the HPMC coated gelatin microcapsules in the commercially available
snuff of Sample 2 was observed to be lower.
EXAMPLE 5
[0154] Microcapsules were formed in the following manner.
[0155] 20.7 g of hydroxypropyl methylcellulose, type 2910, viscosity 3mPa*s (SheffCel 60HD3,
purchased from Kerry) and 2.3 g of talc was mixed with 207 g of water resulting in
a 230 g weight suspension.
[0156] 90 g of Millicaps 1000E_1413279 (from V. MANE FILS, France) was charged in the fluid
bed. The Millicaps were substantially gelatin microcapsules containing a liquid peppermint/menthol
flavorant. The above prepared 230 g weight suspension with talc and dissolved hydroxypropyl
methylcellulose was then sprayed on to the Millicaps 1000E_1413279. Process equipment
and settings for the process as indicated in example 1.
[0157] The formed microcapsules were then sieved through a sieve with a mesh size of 2 mm
and the upper fraction was removed.
[0158] The moist snus was prepared as in example 1. The total amount of moisture of the
snus was about 46 % by weight based on said moist snuff.
[0159] The above manufactured microcapsules were mixed with the moist snus. The composition
of the moist product is indicated in Table 2.
[0160] About 7 g of the above moist product were then stored in a sealed glass bottle for
two weeks at room temperature.
[0161] After storage for two weeks at room temperature the above moist product consisting
of moist snus and microcapsules were evaluated regarding chemical storage stability
as follows.

flavor and one for total flavor. As indicated in table 10, the free flavor content
of the moist snus was only 4.73% after storage 2 weeks in room temperature. It can
be concluded that the HPMC-talc coated gelatin microcapsules containing the liquid
flavorant did not release the flavorant to any significant extent. Thus, the HPMC-talc
coated gelatin microcapsules containing the liquid flavorant are substantially storage
stable in the moist snus.

[0163] Moist snus was prepared by mixing sodium carbonate, ethanol and water with grinded
and heated moist tobacco. The amounts were as indicated in Table 11 below. The total
amount of moisture of the snus was about 46 % by weight based on said moist snus.
Thus, the moist snus of the moist snus product consisted of grinded and heated moist
tobacco prepared as described above, sodium carbonate, ethanol and water in amounts
as indicated in Table 11.
[0164] Microcapsules manufactured as in Example 5 were mixed with the moist snus to provide

as follows.
[0167] Analysis regarding content of menthol was performed in two batches, one for free

Thus, lowering the salt content decreases the stability of the microcapsules in the
moist snus.
EXAMPLE 7
[0169] Moist snus was prepared by mixing sodium chloride, sodium carbonate, ethanol and
water with grinded and heated moist tobacco. The amounts were as indicated in Table
13 below. The total amount of moisture of the snus was about 46 % by weight based
on said moist snus. Thus, the moist snus of the moist snus product consisted of grinded
and heated moist tobacco prepared as described above, sodium chloride, sodium carbonate,
ethanol and water in amounts as indicated in Table 13.
[0170] Microcapsules manufactured as in Example 5 were mixed with the moist snus to provide

of the moist snus was only 4.67% after storage 2 weeks in room temperature. It can
be concluded that the HPMC-talc coated gelatin microcapsules containing the liquid
flavorant did not release the flavorant to any significant extent. Thus, the HPMC-talc

[0176] About 7 g of the above moist product were then stored in a sealed glass bottle for
two weeks at room temperature.
[0177] After storage for two weeks at room temperature the above moist product consisting
of moist snus and microcapsules were evaluated regarding chemical storage stability
as follows.
[0178] Analysis regarding content of menthol was performed in two batches, one for free
flavor and one for total flavor. As indicated in table 16, the free flavor content
of the moist snus was 29.1% after storage 2 weeks in room temperature.

| *The free flavor content in Table 16 was calculated as: Free flavor (%) = Average
area free flavor / Average area total flavor |
[0179] As indicated above, the average area free flavor is 1831060, and the average area
total flavor is 6281680. It follows that the free flavor is 1831060/6281680=29.1%.
Thus, lowering the salt content decreases the stability of the microcapsules in the
moist snus.
EXAMPLE 9
[0180] Moist snus was prepared by mixing sodium carbonate, sodium chloride, potassium sulphate,
propylene glycole, ethanol and water with grinded and heated moist tobacco. The amounts
were as indicated in Table 17 below. The total amount of moisture of the snus was
about 46 % by weight based on said moist snus. Thus, the moist snus of the moist snus
product consisted of grinded and heated moist tobacco prepared as described above,
sodium carbonate, sodium chloride, potassium sulphate, propylene glycole, ethanol
and water in amounts as indicated in Table 17.
[0181] Microcapsules manufactured as in Example 5 were mixed with the moist snus to provide
a moist snus product. The composition of the moist snus product is indicated in Table
17.

[0183] After storage for two weeks at room temperature the above moist product consisting
of moist snus and microcapsules were evaluated regarding chemical storage stability
as follows.
[0184] Analysis regarding content of menthol was performed in two batches, one for free
flavor and one for total flavor. As indicated in table 18, the free flavor content
of the moist snus was only 5.3% after storage 2 weeks in room temperature. It can
be concluded that the HPMC-talc coated gelatin microcapsules containing the liquid
flavorant did not release the flavorant to any significant extent. Thus, the HPMC-talc
coated gelatin microcapsules containing the liquid flavorant are substantially storage
stable in the moist snus.

EXAMPLE 10. Measurement of conductivity of moist snus.
[0185] The following method may be used to measure the conductivity of moist snus. Equipment:
conductivity measurement apparatus, glass beaker and a magnetic stirrer. Procedure:
Mix 1.5 g of moist snus with distilled water until the total weight becomes 450.0
g. The thus obtained mixture is stirred using the magnetic stirrer at about 200 rpm
for about 2 minutes. A probe of the measurement apparatus is dipped into the thus
obtained mixture a couple of times until a stable conductivity value is obtained.
The mixture is allowed to stand for about 1 minute. The obtained conductivity value
is recorded.
