Field of application
[0001] The present invention relates in general to the technical field of frozen ready-made
meals.
[0002] More particularly, the present invention relates to a packaged frozen ready-made
meal, suitable for heating in a microwave oven, comprising at least two food products
intended to come into contact with one another at the time of consumption.
[0003] The present invention also relates to a method for the production of the frozen ready-made
meal of the invention.
Prior art
[0004] To meet the needs of an ever-growing number of consumers who do not always have the
time or the means necessary for preparing a hot meal in a conventional manner, the
food industry has long been making available various packaged food products suitable
for being rapidly cooked, heated or reconstituted, thus allowing the preparation of'
hot meals in little time and with the aid of' few pieces of equipment or kitchen tools.
[0005] Such products are usually referred to as "ready-made meals" or "ready to heat", "heat
and go", "ready meal", etc.
[0006] Such products are particularly suitable for meeting the needs of those who wish to
eat a hot meal outside the home, such as for example at the workplace, and in general
in places where there is no access to the use of a well-equipped kitchen. Such products
are also suitable for home use in all those circumstances in which there is not the
time, nor the possibility, of cooking a hot meal in a conventional manner.
[0007] Among the wide range of packaged ready-made meals made available by the industry,
one specific type consists of first course meals based on two food components: a main
component, generally cereal-based, such as pasta or rice, mixed or to be mixed with
a condiment, generally of a liquid or semi-liquid consistency. Such ready-made meals
can for example consist of pasta, rice, filled pasta,
gnocchi, cereal grains, and a sauce as a condiment.
[0008] More commonly these products are packaged in sachets, trays, cups or combinations
of these, and can be frozen, sterilised or freeze-dried.
[0009] In the case of frozen ready-made meals, they very often exhibit the food components,
for example a pasta and a sauce, already mixed and placed in a tray, cup or other
type of receptacle suitable for heating in a standard or microwave oven. The consumer
is only required to heat the product thus packaged, following the instructions, which
may include preparation steps to the process of heating the product, such as the removal
of a film or wrapping, or the transfer of the product onto a plate or into a suitable
container, or stirring or mixing of the product, depending on the specific cases.
[0010] This solution has the drawback, however, of producing a meal which is often disappointing
from an organoleptic point of view, because the prolonged contact between the various
components of the product during production of the ready-made meal and during its
subsequent thawing and heating causes migration of the water from one component to
the other, which causes a deterioration in its texture and flavour. Moreover the product
may be unevenly heated, with certain parts of the product which are overcooked or
too dry or even burnt, having been exposed to heat for an excessively long time, and
with other parts having been exposed for too short a time, for example the innermost
parts, which are still cold and in certain cases even still frozen at the time of
consumption.
[0011] Moreover the possible need to remove films or even only to mix the product during
or after heating obliges the consumer to perform a number of preparation steps with
a consequent waste of time, the need to soil kitchen tools and the risk of staining
clothes or of soiling the work surfaces and the surfaces of the oven.
[0012] Other solutions involve the separation of the two components up to the time of their
consumption, subsequent to their heating, for example in a microwave oven. Please
see, by way of example, Japanese patent
JP 2296683 (Otsuka Chemical Co. Ltd), which describes a packaging consisting of a receptacle
containing a solid food such as for example rice or pasta, underlying a lid which
receives inside a frozen condiment which becomes fluid upon heating. The receptacle
and the lid are separated by a partition which has a hole. Upon heating, steam is
generated by the sauce in the lid and there is an increase in the pressure which pushes
the sauce through the hole and into the receptacle.
[0013] This solution, though more satisfactory compared to that described previously, suffers
from the drawback of requiring a somewhat complex and therefore relatively costly
packaging. Moreover it can happen that, owing to production defects or simply owing
to chance, the hole does not allow the easy passage of the fluid condiment, for example
in the case wherein the hole becomes clogged at the passage of the condiment. Moreover
such packaging is not suitable for use with sauces including granulated ingredients
as the latter could clog the hole. This entails a limitation in the range of recipes
which are suitable for being used in association with this packaging.
[0014] The document
JP 8332040 (Kiyuusai KK) describes packaged frozen noodles wherein a receptacle contains frozen
noodles, (separately) packaged crushed ice, a (separately) concentrated and packaged
sauce and a (separately) packaged condiment. To prepare this ready-made meal the packagings
of ice, sauce and condiment have to be removed from the receptacle and the receptacle
with the noodles is then placed in a microwave oven until the noodles are heated.
The receptacle is then removed from the oven, the ice is added to the noodles and
mixing is performed to melt the ice. The sauce and condiment are then added and the
noodles are cooked.
[0015] Although it may be satisfactory from an organoleptic standpoint, this solution appears,
however, somewhat work-intensive in that it involves the consumer performing numerous
operations during the entire preparation of the ready-made meal. Moreover, in order
to perform these operations, the consumer is forced to interrupt the heating process,
with the result that there will be two heating steps. This, as well as being demanding
on the consumer who must actively attend to the preparation of the ready-made meal,
also entails a slowing-down of the preparation time of the ready-made meal with consequent
additional disadvantage for the consumer.
[0016] The need therefore arises to make available a packaged frozen ready-made meal suitable
for a simple, easy, rapid, even and, organoleptically satisfactory heating, in a microwave
oven, according to a method which does not require any additional expedient, preparation
step or tool before or during heating and which thus overcomes all the inconveniences
encountered in the prior art.
Summary of the invention
[0017] A similar problem has been solved, according to the invention, by a packaged frozen
ready-made meal comprising a flared receptacle made of rigid material permeable to
microwaves, containing a first frozen food component, at the bottom, a second frozen
food component having a substantially plate-like shape, having a substantially fluid
consistency at a temperature above 0°C, and a closure element,
characterised in that said second frozen food component having a substantially plate-like shape engages
in the manner of a plug with the internal wall of said receptacle, spaced apart from
said first frozen food component.
[0018] Such flared receptacle is preferably substantially cup-shaped.
[0019] Such flared receptacle is preferably tapered.
[0020] According to a preferred embodiment the flared receptacle has an overturned truncated
conical shape and the second frozen food component having a substantially plate-like
shape is discoidal in shape.
[0021] The first food component is preferably a cereal-based frozen food chosen from the
group consisting of: pasta, rice, spelt, barley, filled pasta,
gnocchi, vegetables, preferably pasta.
[0022] The second food component is preferably a tomato-, cheese-, oil-, béchamel-based
condiment, optionally containing meat or fish, or the like, preferably tomato-based.
[0023] In a preferred embodiment the packaged frozen ready-made meal comprises at the bottom
of the abovementioned receptacle a predetermined quantity of ice or frozen aqueous
solution, generally 5% or lower based on the total weight of said first and second
food components.
[0024] Such aqueous solution can consist of a sodium chloride solution at a concentration
of 1-2% in weight over volume.
[0025] The receptacle preferably consists of a rigid plastic material suitable for use in
a microwave oven and permeable to microwaves. The closure element comprises a film
of plastic material sealed on the edges of the receptacle. Such film is preferably
provided with perforations of adequate size for allowing the release of the steam
generated during heating, when it exceeds a predetermined pressure, above atmospheric
pressure.
[0026] The holes of the closure film generally have a diameter of 0.2-0.4 mm and are found
in a number comprised between 50 and 100, preferably arranged in parallel rows.
[0027] A controlled maintenance of a slight excess pressure inside the receptacle, in fact,
accelerates the heating of the foods contained therein.
[0028] The closure element may further comprise a lid, also made of a rigid plastic material.
[0029] The abovementioned plastic material is preferably chosen from the group comprising
polypropylene (PP), polyethylene (PE) and polyethylene terephthalate (PET).
[0030] The closure element is preferably made of the same material as the receptacle. The
abovementioned closure film preferably consists of coupled PP/PET, the side of the
film facing the exterior of the packaged frozen ready-made meal consisting of PET.
[0031] The closure film can also consist of a PE-based multilayer film, containing a layer
having oxygen barrier properties. The material which makes up the gas barrier layer
can be chosen from the group comprising polymers and copolymers of ethylene vinyl
alcohol (EVOH), nylon, polyvinylidene chloride (PVDC), poly or copolyamides and their
combinations, oxides of metals/silicon. The abovementioned material is preferably
a polymer or copolymer of ethylene vinyl alcohol or nylon.
[0032] In the case of use of a film and of a receptacle with gas barrier properties, the
holes in the closure film are closed by a barrier label or barrier lacquer and they
open up during heating thanks to the temperature and the pressure, allowing the release
of steam.
[0033] In a particularly preferred embodiment the packaged frozen ready-made meal according
to the present invention further comprises a rigid cardboard container intended to
receive and contain the abovementioned flared receptacle with such clearance as to
create an interspace between the container and the receptacle, at the respective lateral
walls and optionally also at the respective bottoms. In such way, it is easier for
the consumer to handle the packaged ready-made meal, once it has been taken out of
the microwave oven, because the abovementioned interspace prevents the external cardboard
container from heating up excessively and averts any risk of scalding the consumer.
[0034] Additional protection against accidental scalding is obtained when the aforementioned
closure element comprises, in addition to the closure film, also a lid of rigid plastic
material, above all when such lid is placed above the closure film spaced apart therefrom,
so as to create an interspace.
[0035] According to a particularly advantageous embodiment of the packaged frozen ready-made
meal according to the present invention, the abovementioned lid exhibits on its outer
upper surface a recess of circular shape suitable for receiving, once it has been
removed, by press fit engagement, the bottom of the external cardboard container of
the packaged frozen ready-made meal, thus constituting a convenient support stand
for such container.
[0036] The packaged frozen ready-made meal according to the invention preferably comprises
a quantity of the two food components suitable for forming a single-portion ready-made
meal.
[0037] The present invention moreover refers to a method for the production of the packaged
ready-made meal of the invention which comprises the steps of:
- a) introducing in a flared receptacle as described above an appropriate quantity of
a first food component, optionally frozen;
- b) introducing a second frozen food component as described above in the flared receptacle
containing the first food component in such a way that the second food component is
engaged with the internal wall of the receptacle in the manner of a plug and spaced
apart from the first component below;
- c) closing said flared receptacle (2) by means of said closure element (3);
- d) freezing the lot.
[0038] Preferably such flared receptacle is substantially cup-shaped.
[0039] According to a preferred embodiment, the flared receptacle has an overturned truncated
conical shape and the second frozen food component having a substantially plate-like
shape is discoidal.
[0040] The first food component is preferably a cereal-based food chosen from the group
consisting of: pasta, rice, spelt, barley, filled pasta,
gnocchi, vegetables, preferably pasta, and may be ready-frozen.
[0041] The second food component is preferably a tomato-, cheese-, oil-, bechamel-based
condiment, optionally containing meat or fish, or the like, preferably tomato-based.
[0042] In a preferred embodiment, the method comprises an additional step of introduction
of a predetermined quantity of water or of an aqueous solution inside said flared
receptacle before performing the abovementioned step a).
[0043] The quantity of water or of aqueous solution is preferably 5% or lower based on the
total weight of' said first and second food components.
[0044] Such aqueous solution preferably consists of a sodium chloride solution at a concentration
of 1-2% in weight over volume.
[0045] The method preferably uses a receptacle consisting of a rigid plastic material suitable
for use in a microwave oven and permeable to microwaves.
[0046] The quantity of the two food components is preferably suitable for forming a single-portion
ready-made meal.

Detailed description of the invention
[0048] With reference to the drawings, reference numeral 1 identifies the overall packaged
ready-made meal according to an embodiment.
[0049] The receptacle 2 is of the type suitable for being used in a microwave oven and is
provided with a closure element 3, consisting of a closure film 31 provided with perforations
32 and a lid 33, preferably of the same material as the receptacle.
[0050] The materials used for making the receptacle 2 and the closure element 3 are all
specifically permeable to microwaves and suitable for being exposed to the microwaves
without spoiling the organoleptic qualities of the food products with which they come
into contact. More particularly they are preferably made with plastic materials suitable
for use in a microwave oven, for example polypropylene.
[0051] The receptacle is rigid and flared and may be substantially cup-shaped. According
to a preferred embodiment, shown in the drawings, the receptacle 2 has an overturned
truncated conical shape and rests on its base 4, which corresponds to the smaller
base of the truncated conical frustum. In this embodiment the receptacle is tapered
along the entire lateral wall 5.
[0052] On the bottom of the receptacle, resting on the base 4 of the receptacle 2, is housed
the first food component 6, which, according to a preferred embodiment, consists of
a portion of pasta. Such pasta is partially cooked and unseasoned and may have been
frozen in a loose state. The second food component 7, which, according to a preferred
embodiment consists of a frozen tomato-based sauce, has a plate-like shape. In a preferred
embodiment and as can be seen more clearly in Figure 2, such second component has
a disc shape. The dimension of the diameter of such disc is such that, as can be seen
in Figure 1, the disc is engaged with the flaring of the receptacle and thus remains
spaced apart from the first food component 6 below. Obviously the second food component
having a plate-like shape can also have other shapes, provided they are suitable for
enabling a spacing apart from the first food component contained in the receptacle;
for example, if a receptacle having an oval cross section is used, the second food
component having a plate-like shape will also conveniently be oval-shaped.
[0053] It is by virtue of the generally flared, or tapered, shape of the receptacle in fact
that the first and the second food components are spaced apart with respect to each
other.
[0054] During thawing and heating of the packaged ready-made meal 1 in a microwave oven,
both food components 6 and 7 heat up. In particular the first component 6, below,
heats up rapidly and evenly by virtue of its relatively large surface of exposure
to the microwaves. The second component 7, engaged with the internal lateral surface
in the manner of a plug, passes from the solid state to the fluid state as it heats
up, thus losing its engagement with such surface and sliding by gravity towards the
base of the receptacle, and consequently onto the first component.
[0055] In this way, for most of the heating time, the first 6 and the second 7 food components
have all their respective external surfaces exposed to the microwaves. Thanks to this
expedient, the heating time is optimised and the heating is therefore even and satisfactory.
[0056] In turn, the reduction in the heating time and the evenness in heating result in
a better preservation of the consistency of' the end product ready for consumption
compared to the prior art, as no part of the food components is subjected to excessive
and inadequate heat treatment and, at the same time, it does not occur that there
are cold areas left when other areas have already been excessively heated.
[0057] The heating will not spoil, therefore, the original organoleptic properties of the
components which will be optimal and thus, for example, the pasta will be "al dente"
and the rice will have the desired texture.
[0058] The two food components will then come into contact at a fairly advanced stage of
the heating, when the second component is thawed and in the fluid state.
[0059] It has been found in fact that, in order to preserve the optimal properties of consistency
and flavour, it is preferable for the first food component, for example the pasta,
not to be placed in contact with the second component, for example a tomato-based
sauce, during the entire time of production and of subsequent thawing and heating
of the frozen packaged ready-made meal. The two components can be characterised, in
fact, by different water contents and their prolonged contact during the steps of
production and, subsequently, the step of thawing and heating would cause migration
of the moisture from the higher moisture component to the lower moisture component,
altering the textures of both components and jeopardising their organoleptic characteristics.
[0060] For this reason, in the present invention, the food components do not come into contact
one with the other throughout the entire production and storage time of the packaged
ready-made meal and for most of its heating time.
[0061] As shown in Figure 1, according to a preferred embodiment of the invention, the second
food component 7 is held in engagement with the internal wall of the receptacle thanks
to the conicity of the same. Naturally, a person skilled in the art will easily understand
that other expedients can be used in order to obtain effective engaging with the internal
wall for the purpose of the invention.
[0062] For example, a sharp variation in the section can be made, at a point of the vertical
axis, such that the variation in section forms a horizontal support, at the borders,
for the second plate-like food component.
[0063] Effective engaging with the internal wall of the receptacle can be obtained also,
for example, with the creation of protrusions on the same.
[0064] According to a preferred embodiment of the present invention, the receptacle contains,
additionally, on the bottom, a layer of ice or of frozen aqueous solution.
[0065] In fact, although exposure of the frozen cooked pasta to the microwaves may constitute
an ideal treatment for thawing and heating of the packaged ready-made meal of the
invention, it has been found that an even more homogeneous and therefore even more
satisfactory cooking is achieved by providing a source of steam inside the receptacle.
[0066] The frozen aqueous solution, or ice, in fact, during heating, generates water vapour
which pervades the receptacle, transporting heat and moisture through the first and
the second food component. Thus, cooking is achieved in a steam atmosphere which is
considerably more effective and faster in bringing the food components 6 and 7 to
the desired temperature. Moreover this cooking method allows a more even result to
be obtained in shorter times, and helps prevent the formation of excessively dry areas,
typical, at times, of microwave cooking. The generation of steam from the ice or from
the frozen solution which is found on the bottom of the receptacle compensates the
evaporation of water from the food components contained in the receptacle and reduces
general drying of the latter.
[0067] According to a particular embodiment of the present invention and with reference
to Figs. 2-4, the packaged ready-made meal comprises a rigid receptacle 2, for example
in polypropylene, having an overturned truncated conical shape with a bottom 4 and
an opposite opening, bordered by an edge 8. The edge 8 of the opening is folded outwards
in a U shape so as to form a perimetrical flanging 9 and an underlying perimetrical
grooving 10. Near the free rim of' the folded edge 8 and along the entire circumference
there is a series of protrusions 81 facing inwards.
[0068] The packaged ready-made meal also comprises a container 11, for example of cardboard,
having an overturned truncated conical shape, having a bottom 12 and an opposite opening
bordered by an edge 13; the container 11 receives in its interior the receptacle 2,
which remains suitably centred and positioned thanks to the engaging of the edge 13
of the container 11 to the perimetrical grooving 10 of the receptacle 2 and thanks
to the protrusions 81 of the folded edge 8 of the receptacle 2.
[0069] The receptacle 2 must in fact be introduced in the container 11 by exerting a slight
pressure in such a way that the protrusions 81 pass beyond the edge 13 of the container
11 and then engage it, thus preventing separation of the container 11 from the receptacle
unless a certain force is applied.
[0070] The closure element 3 of the packaged ready-made meal according to the present embodiment
comprises a film 31, for example of coupled PP/PET, provided with perforations 32,
sealed on the flanging 9 of the edge 8 of the receptacle. It also comprises a lid
33, made for example of the same material as the receptacle 2 and having on its upper
surface a circular recess 34, having a diameter substantially corresponding - in practice
slightly greater - to the diameter of the bottom 12 of the container 11. The lid 33
is placed on the opening of the receptacle 2 with a light pressure, so as to engage
the folded edge 8 of such receptacle. Engaging is ensured thanks to a series of protrusions
35 arranged on the internal surface of the edge 36 of the lid 33, near its free rim,
which, once pressed beyond the folded edge 8 of the receptacle 2, engage it and retain
it firmly in position.
[0071] As can be seen clearly in Figure 4, the lid 3, thanks to the presence of the circular
recess 34, once removed from the packaged ready-made meal ready for use, can receive,
by press fit engagement, the bottom 12 of the container 11, so as to form a support
stand for such container.
[0072] Thanks to all the features disclosed hitherto, the packaged ready-made meal according
to the invention has the advantage of allowing a convenient and easy preparation of
the ready-made meal. In fact, for its preparation for consumption by the end consumer,
it is not necessary to use any kitchen tool or piece of crockery, just as it is not
necessary to perform any step of decanting, transferring or mixing, before or during
its heating in the oven.
[0073] The end consumer in fact is only required to introduce the packaged ready-made meal
as it is in the microwave oven, at a power setting between for example 750 and 1800
W, for a time comprised between 2 and 6 minutes.
[0074] At the end of the set heating time the consumer may open the packaged ready-made
meal and consume the ready-made meal directly, for example, with a fork, straight
from the receptacle, after optionally mixing, if desired.
[0075] It has been found experimentally that when using a packaged ready made meal similar
in all aspects to that according to the present invention except for the fact of not
contemplating the separation of the two food components (for example pasta and sauce)
contained in the receptacle (for example mixed and frozen pasta and sauce), the time
necessary for thawing and heating to the temperature of consumption is considerably
greater, typically by 20-25%,
[0076] Since the food components do not come into contact with one another until shortly
before the end of the heating time, and for the reasons disclosed above, it is not
in fact necessary to mix the components during heating. As a result the heating times
are considerably reduced as there are no interruptions while the convenience for the
consumer is considerably increased.
[0077] Compared to the solutions of the prior art which use separate packagings for each
of the two food components (for example pasta and sauce), the consumer will benefit
from the fact of not having to pour one component into the other, or interrupt the
heating process to mix the food components. He or she will not therefore risk staining
clothes or soiling the oven or work surfaces with splashes in any of these steps.
[0078] Another advantageous feature of the present invention is given by the fact that,
by virtue of the special positioning of the second component in relation to the first,
it is possible to detect any interruption of the cold chain which the packaged ready-made
meal may have undergone during its storage and transport In fact, if it were to be
detected, at the time of' purchase or of final preparation, that the second component
is resting on the first component, this would be clear indication of the fact that
the second component has undergone unexpected thawing.
[0079] From the point of view of costs, finally, the present invention entails advantages.
The receptacle of the present invention, in fact, has a simple shape and, for the
purposes of the invention, there is no need for any grooving, ribbing, partitioning
or other similar means, as instead adopted in many cases by the prior art. Therefore
the receptacle and the external container of' the packaging according to the present
invention are economical to produce and easily stackable and therefore convenient
for industrial use
[0080] The present invention will now be described in further detail with reference to a
non-limiting illustrative example.
EXAMPLE 1
[0081] A rigid receptacle 2 in polypropylene was set up having an overturned truncated conical
shape and a bottom 75 mm in diameter, an opening 105 mm in diameter, and 95 mm in
height. The edge 8 of the opening is folded outwards in a U shape so as to create
a perimetrical flanging 9 and an underlying perimetrical grooving 10. The maximum
diameter at the flanging 9 is of about 115 mm.
[0082] 5ml of water and 130 g of partially cooked and unseasoned pasta, i.e. equivalent
to a standard individual portion, were placed on the bottom of' the receptacle.
[0083] Aside, a tomato-based sauce was prepared, comprising the following ingredients, in
weight percentages based on the total weight of the sauce:
Tomato pulp |
83 |
|
Double concentrated tomato paste |
|
6 |
Onion |
3.5 |
|
Extra-virgin olive oil |
3.5 |
|
Salt |
1.25 |
|
Garlic |
1.33 |
|
Chilli pepper |
0.12 |
|
Parsley |
1.3 |
|
[0084] Such sauce was then frozen in disc shapes 95 mm in diameter and about 10 mm thick,
and 120g in weight.
[0085] Such a disc was then placed inside the receptacle containing the pasta.
[0086] Thanks to the tapering of the receptacle and the dimensions of the sauce disc, the
disc remained engaged with the wall of the surface of the receptacle in the manner
of a plug, spaced apart from the pasta. The distance between the sauce and pasta was
of about 10 mm.
[0087] The receptacle 2 was then closed with a film 31. of coupled PP/PET, provided with
perforations 32, sealed on the flanging 9 of the edge 8 of the receptacle. The holes
32 were arranged, in a total number of 83, in three parallel rows spaced apart by
18 mm, one of which passing through the diameter of the opening of the receptacle
2. Each hole had a diameter of 0.3 mm and was spaced apart from the adjacent hole/holes
by 3.7 mm. This configuration has been shown to allow the maintenance of a slight
excess pressure inside the receptacle without the risk of creating tensions in the
film such as to cause its detachment.
[0088] The receptacle 2 was then placed inside a cardboard container 11 having an overturned
truncated conical shape, whose bottom 12 has a diameter of about 83 mm and whose opening
has a diameter of about 115 mm. The container 11 is about 100 mm in height and can
receive in its interior the receptacle 2, which remains suitably centred and positioned
thanks to the engaging of the edge 13 of the container 11 to the perimetrical grooving
10 of the receptacle 2 and thanks to the protrudings 81 found inside the edge 8 of
the receptacle 2.
[0089] A lid 33 made of the same material as the receptacle 2, having a diameter of 120
mm and exhibiting on its upper surface a circular recess 34, having a diameter of
about 85 mm, is finally placed on the opening of the receptacle 2 with a light pressure
in such a way as to engage the folded edge 8 of such receptacle. Engaging is ensured
thanks to a series of protrudings 35 arranged on the internal surface of the edge
36 of the lid 33, near its clear rim, which, once pressed beyond the folded edge 8
of the receptacle 2, engage it and retain it firmly in position.
[0090] The packaged frozen ready-made meal completed in this way is then frozen and stored
in the freezer at a temperature of -18°C or lower.
EXAMPLE 2 (COMPARATIVE)
[0091] The same receptacle 2, the same container 11 and the same lid 33 used in the preparation
of the packaged frozen ready-made meal according to example 1 were used.
[0092] Also in this case, 5ml of water and then 130g of partially cooked pasta and 120g
of the tomato-based sauce of example 1 were placed in the receptacle on the bottom
of the receptacle 2.
[0093] The receptacle 2 was then closed with the same film of coupled PET/PP as per example
1, having the same perforations.
[0094] The packaged frozen ready-made meal was completed by the same procedures as per example
1, using the same container 11 and the same lid 33, and was then frozen and finally
stored in the freezer at a temperature of -18°C or lower.
EXAMPLE 3
[0095] The packaged ready-made meals according to Examples 1 and 2 were prepared with a
microwave oven to assess their organoleptic properties.
[0096] The two packaged ready-made meals were placed in a microwave oven, still sealed with
the lid, and a power of 900 W was applied. The time of treatment in the microwave
oven was 4 minutes for the packaged ready-made meal according to example 1 and 5 minutes
for the packaged ready-made meal according to example 2.
[0097] At the end of the set time the packaged ready-made meals were opened and their content
was inspected.
[0098] As can be seen in Figure 5, referring to a packaged ready-made meal according to
example 1 and therefore according to the present invention, the pasta contained in
the cup is completely covered with the tomato-based sauce.
[0099] In Figure 6, referring to the comparative example 2, it can be seen that some pieces
of pasta emerge from the sauce and exhibit clear signs of burning (above all those
which are found near the wall of the receptacle).
[0100] The average temperature of the product contained in each of the two packaged ready-made
meals was also measured and it was found that in both cases such average temperature
was around 65°C.
[0101] The pasta contained in the packaged ready-made meal as per example 1 has, in an even
manner, the moisture content and the consistency typical of freshly cooked conventional
pasta whereas the pasta contained in the packaged ready-made meal according to example
2 is uneven as regards moisture content and consistency, with single pieces of pasta
being particularly dehydrated and occasionally burnt in the uppermost layers and above
all near the wall of the receptacle.
[0102] Without wishing to be bound by theory, it is believed that the frozen disc of sauce
protects the underlying pasta from excessive dehydration, preventing the release from
the container of the water vapour generated during heating. The steam retained below
the sauce also contributes to the even and rapid heating of the pasta.
[0103] Obviously a person skilled in the art, for the purpose of satisfying contingent and
specific needs, may make numerous modifications and variations to the invention described
above, all moreover contained within the scope of protection of the invention as defined
by the following claims.
