Description

FIELD OF THE INVENTION



[0001] The present invention relates to a whipping agent for use in the preparation of edible toppings. The invention further relates to a method for preparing such a whipping agent, to an instant edible powder comprising said whipping agent, a method of preparing a whipped topping comprising the whipping agent and an edible topping prepared from said whipping agent.

BACKGROUND OF THE INVENTION



[0002] Whipping agents are well-known products in the food industry. Whipping agents or aerating agents are typically spray-dried compositions comprising fat, one or more emulsifiers, carbohydrates and protein. These powdered compositions are most often used in the preparation of instant desserts, cake filling, ice cream. etc. For example, such desserts are prepared by adding a liquid, e.g. milk, to the instant powder and subsequently whipping the mixture, resulting in a whipped topping. These whipped toppings have a certain stability over time, in which the shape of the whipped topping is substantially retained. These types of instant desserts generally comprise besides the whipping agent and the liquid also sugar, texturizing agents such as hydrocolloids, coloring agents and flavoring agents.

[0003] Whipping agents used for preparing the above mentioned kinds of food products generally comprise significant amounts of emulsifiers and edible oil. Emulsifiers are added to foods, in particular whipping agents, for several reasons. They are amongst others used to influence the overrun, consistency, stability and organoleptic properties.

[0004] Without wishing to be bound by any theory it is assumed that emulsifiers increase the stability of emulsions through the creation of liquid crystals or by means of cooperative interactions with proteins, which are typically found in food products. Another important functionality of emulsifiers is to induce controlled destabilization. This destabilization is very important in whippable emulsions (e.g. mousse, whipping creams, ice cream etc.) and can be achieved by adding emulsifiers of various polarities. The destabilization process involves several physical changes of the emulsion taking place at low temperature, such as crystallization of the fat phase and partial desorption of interfacial protein, resulting in a decrease in emulsion stability under shear.

[0005] The function of emulsifiers, such as monoglycerides, diglycerides or lactic acid esters thereof is thus to decrease the emulsion stability under shear, resulting in the formation of clusters of agglomerated fat particles, which during aeration form a structure around and between the air cells, stabilizing the foam structure. The agglomerated fat phase contributes to the creaminess and the stability of the foam. Besides emulsifiers, whipping agents also comprise a significant amount of an edible (bulk) oil or fat. Until recently, palm kernel oil was, and is, commonly used in these kinds of whipping agents. However, the use of palm based products has become increasingly controversial, due to environmental issues.

[0006] Hence, whipping agents have been developed, which do not comprise palm kernel oil or derivates thereof as the edible fat fraction. However, the emulsifiers used are still derived from palm oil, such as lactic acid esters of mono and diglycerides derived from palm oil.

[0007] Although, the amount of such emulsifiers used is generally lower than the amount of edible (bulk) fat or oil used, a need remains to also substitute the palm oil based emulsifiers with more sustainable types of emulsifiers, i.e. non palm oil based emulsifiers. This way food manufactures would be able to prepare products which are completely free from palm based emulsifiers and palm based (bulk) oil and fat.

[0008] A need thus remains to substitute in whipping agents both the palm based edible (bulk) fat or oil (e.g. palm kernel oil)as well as the palm oil based emulsifiers for non-palm based fats, oils and emulsifiers, whilst maintain a good performance of the whipping agent.

SUMMARY OF THE INVENTION



[0009] A first aspect of the present invention relates to a whipping agent for use in the preparation of edible toppings comprising on a dry weight basis:
  • 25 to 75% by weight of a non-palm based edible oil or fat;
  • 5 to 30 % by weight of a non-palm based alpha tending emulsifier;
  • 1 to 15% by weight of a proteinaceous emulsifier; and
  • 25 to 60% by weight carbohydrates.
With the present invention it has now for the first time become possible to prepare a whipping agent which is free from palm based (bulk) edible oil and fat and which is also free from palm based emulsifiers and which still has a very good performance with respect to overrun, consistency, stability and organoleptic properties.

[0010] A second aspect of the present invention relates to a method for preparing a whipping agent according to the present invention. This method comprises the following steps:
  1. i. mixing a proteinaceous emulsifier and carbohydrates with water, such that an aqueous mixture is obtained;
  2. ii. adding the non-palm based edible oil or fat and the non-palm based alpha tending emulsifier to the mixture;
  3. iii. spray drying said mixture, such that a powder is obtained.


[0011] The spray dried powder obtainable by the above mentioned method has a very good shelf-life. Tests have shown that an exceptionally good performance is still obtained after one year of storage of the powder. Even after two years of storage, very good products were prepared from the spray-dried powder.

[0012] A third aspect of the present invention relates to an instant edible powder composition comprising the whipping agent according to the present invention and further comprising one or more substances chosen from sugar, milk powder, hydrocolloids, coloring agents, flavoring agents, or a combination thereof.

[0013] This instant edible powder may be mixed with a fluid and whipped, such that a stable foam like product is obtained.

[0014] A further aspect of the present invention also relates to a method for preparing a whipped topping comprising the whipping of a whipping agent according to the invention in a food acceptable liquid, such as milk, to an overrun of 50-400%.

[0015] A last aspect of the present invention relates to an edible topping prepared from the whipping agent according to the present invention.

DETAILED DESCRIPTION OF THE INVENTION



[0028] A first aspect of the present invention relates to a whipping agent for use in the preparation of edible toppings comprising on a dry weight basis:
  • 25 to 75% by weight of a non-palm based edible oil or fat;
  • 5 to 30 % by weight of a non-palm based alpha tending emulsifier;
  • 1 to 15% by weight of a proteinaceous emulsifier; and
  • 25 to 60% by weight carbohydrates.
Over the last years, the use of palm oil in food products has become increasingly controversial due to sustainability considerations. More and more consumers are of the opinion that cultivation of palm trees for the production of palm oil or palm kernel oil is associated with deforestation in tropical countries and the associated endangerment of species, such as orangutans and tigers. In view of these developments, food manufactures are seeking alternatives to palm oil, palm kernel oil and products derived therefrom, such as emulsifiers.

[0029] Whipping agents which do not comprise any palm derived bulk fat or palm derived (alpha-tending) emulsifiers are hitherto not available on the market.

[0030] In the art, there is moreover a high preference to use fully hardened palm kernel fat, because of its good resistance to oxidation, and the better whipping properties (as compared to non-hardened palm kernel fat).

[0031] With the present invention it has now become possible to prepare whipping agents with excellent properties, but without having to use palm based oils or emulsifiers.

[0032] In the whipping agent according to the present invention the non-palm based edible (bulk) oil or fat is preferably a vegetable oil or fat, more preferably the vegetable oil or fat is fully hydrogenated.

[0033] The vegetable oil or fat is preferably chosen from coconut oil, almond oil, cocoa butter, cotton seed oil, hazelnut oil, linseed oil, maize oil, olive oil, peanut oil, rapeseed oil, safflower oil, soybean oil, sunflower oil, high oleic sunflower oil and mixtures or fractions of any of these oils or fats. More preferably the vegetable oil or fat is chosen from coconut oil, rapeseed oil and mixtures or fractions of any of these oils or fats.

[0034] In an alternative embodiment the non-palm based edible (bulk) oil or fat in the whipping agent according to the present invention is preferably an animal oil or fat, preferably the animal oil or fat is selected from milk fat or butter oil and mixtures or fractions of any of these oils or fats.

[0035] The preferred non-palm based edible oil is coconut oil, preferably non-hardened coconut oil.

[0036] In a preferred embodiment of the present invention, the non-palm based edible oil or fat comprises at least 70% by weight, preferably at least 80% by weight and most preferably at least 90% by weight coconut oil, preferably refined coconut oil. With respect to coconut oil it is noted that it comprises only a relatively low amount of palmitic fatty acid residues (C16:0), i.e. between 7 and 10% by weight.

[0037] The amount of non-palm based edible (bulk) oil or fat in the whipping agent according to the invention is preferably between 25- 65 wt.%. More preferably the amount of non-palm based edible oil or fat is between 30-55 wt.%, most preferably the amount of non-palm based edible oil or fat is between 35-50 wt.% based on the whipping agent.

[0038] Furthermore, at present a large part of the emulsifiers used in whipping agents are still based on palm oil. Although a need exists to also replace these emulsifiers, the development of whipping agents which do not comprise palm oil based emulsifiers has not been straightforward. This has to do with the unique properties of palm oil.

[0039] From Table 1 below, it is clear that palm oil comprises exceptionally high amounts of palmitic (C16:0), oleic (C18:1), linoleic (C18:2) and linolenic (C18:3) fatty acids. Furthermore, the unsaturated fatty acids may readily be hydrogenated, such that a very high amount of saturated fatty acids is obtained. These properties make palm oil particularly suitable to be used as a source for the preparation of emulsifiers, such as alpha tending emulsifiers.
Table 1: Typical fatty acid composition of palm oil in % by weight

C18:0 4.4
C18:1 39.0
20:0 0.2
18:2 10.6
18:3 0.3


[0040] With the present invention it has now for the first time become possible to prepare a whipping agent wherein the palm kernel oil (i.e. the edible bulk oil/fat) has been replaced by a non-palm based oil and wherein also the emulsifiers are non-palm based. Remarkably, the whipping agent according to the present invention still has a very good performance with respect to overrun, consistency, stability and organoleptic properties.

[0041] The non-palm based alpha tending emulsifier used in the whipping agent according to the present invention preferably comprises organic acid esters of non-palm based vegetable oils or propylene glycol mono-esters of non-palm based vegetable oils, such as non-palm based propylene glycol mono-stearate (PGMS).

[0042] The whipping agent according to the present invention preferably comprises 7-28 wt.% of the non-palm based alpha tending emulsifier. More preferably the whipping agent comprises 9-26 wt.% of the non-palm based alpha tending emulsifier, most preferably the whipping agent comprises 11-24 wt.% of the non-palm based alpha tending emulsifier.

[0043] In a particularly preferred embodiment of the present invention the non-palm based alpha tending emulsifier is a lactic acid ester of a non-palm based vegetable oil or an acetic acid ester of a non-palm based vegetable oil. Depending on the intended use, the vegetable oil used for preparing these emulsifiers have preferably been hydrogenated, more preferably they have fully been hydrogenated. As a result, also the non-palm-based alpha tending emulsifiers are preferably fully hydrogenated.

[0044] Preferably, the non-palm based alpha tending emulsifiers comprise less 35% by weight, preferably less than 25% by weight palmitic fatty acid residues (C16:0). If the vegetable oil used for preparing the alpha tending emulsifiers has been hydrogenated, preferably more than 75% by weight, more preferably more than 80% by weight, of the fatty acid residues are stearic acid residues (CI8:0). This level of saturated stearic fatty acid residues cannot be achieved with palm oil based vegetable oils, because the total amount of C18 fatty acids (saturated and unsaturated) is too low.

[0045] Preferably, the non-palm based alpha tending emulsifier used comprises lactic acid esters of a monoglyceride and/or diglyceride, wherein the fatty acids of said glycerides are saturated or unsaturated and wherein the fatty acids have 6 to 30 carbon atoms.

[0046] In a preferred embodiment of the present invention the alpha tending emulsifier is a lactic acid ester of a hydrogenated or non-hydrogenated soy bean oil, sunflower oil, rapeseed oil or a fraction thereof. More preferably, the alpha tending emulsifier is chosen from lactic acid esters of hydrogenated or non-hydrogenated low-erucic rapeseed oil (LEAR).

[0047] Alternatively the alpha tending emulsifier is a lactic acid ester of hydrogenated or non- hydrogenated low-linolenic rapeseed oil (LLCAN) or a lactic acid ester of hydrogenated or non-hydrogenated high oleic rapeseed oil (HOCAN), or a fraction of any of these oils. In this regard it is further noted that the alpha tending emulsifier may also be a mixture of any of the above mentioned rapeseed oils or fractions thereof.

[0048] In relation to the above, it has further been found that it is particularly preferred to use lactic acid esters of hydrogenated rapeseed oil or hydrogenated fractions thereof, more preferably fully hydrogenated rapeseed oil or fractions thereof are used.

[0049] In table 2, the fatty acid composition of some fractions of rapeseed oil has been described.
TABLE 2: Typical fatty acid composition of fractions of rapeseed oil in % by weight
Fatty acidLow-erucic rapeseedLow linolenicHigh oleic rapeseed

22:1 0.2 0.1 0.1
18:2 21.7 28.1 9.8
18:3 9.6 2.1 2.6


[0050] From this table it is clear that upon fully hardening of these fractions of rapeseed oil the total amount of C18:0 will be very high, which is considered advantageous.

[0051] In a preferred embodiment the ratio by weight of the non-palm based edible oil or fat and the non-palm based alpha tending emulsifier is between 1:1 and 20:1, more preferably said ratio is between 1.5:1 and 16:1 and most preferably said ratio is between 2:1 and 8:1.

[0052] The proteinaceous emulsifier of the whipping agent according to the present invention may be from vegetable, or animal origin. Vegetable proteinaceous emulsifiers are preferably selected from pea proteins or soy proteins, more preferably from pea proteins. Animal proteinaceous emulsifiers are preferably selected from milk proteins and/or caseinates, more preferably from caseinates.

[0053] The proteinaceous emulsifier of the whipping agent according to the present invention preferably comprises at least 80% by weight of a caseinate salt, more preferably at least 90% by weight of the whipping agent. The casein salt is preferably sodium caseinate or calcium caseinate or a mixture thereof. The caseinate salt may be spray dried or roller dried.

[0054] Alternatively, the proteinaceous emulsifier used in the whipping agent according to the present invention preferably comprises at least 80% by weight of total milk protein, more preferably at least 90% by weight of milk protein. The milk protein is preferably derived from bovine milk.

[0055] In a particularly preferred embodiment of the present invention the non-palm based edible oil is coconut oil, preferably refined coconut oil, or a fraction thereof, the non-palm based alpha tending emulsifier is a hydrogenated lactic acid ester of rapeseed oil, preferably fully hydrogenated low-erucic rapeseed oil and the proteinaceous emulsifier is a caseinate salt, preferably sodium caseinate.

[0056] In addition, the composition may contain additional, preferably non-palm, emulsifiers selected from the group of: mono- diglycerides not being alpha tending; SSL (sodium stearoyl lactylate; CSL (calcium stearoyl lactylate); DATEM (diacetyl tartaric acid ester of mono- and diglycerides); TWEEN 60 (Polysorbate 60 (polyoxyethylene (20) sorbitan monostearate); TWEEN 80, (polyoxyethylene (20) sorbitan monooleate); sucrose esters of fatty acids; PGE (polyglycerol esters of fatty acids), to modify structure, aeration etc, in an amount of preferably less than 5% by weight of the whipping agent.

[0057] The carbohydrates used in the composition of the invention comprise carbohydrates customary in the art for manufacturing whipping agents; preferably these carbohydrates comprise for example mono and/or disaccharides, (sucrose, glucose, lactose, fructose), hydrolyzed starches like glucose syrups, preferably having a DE (dextrose equivalents) between 26-50 (in liquid or in dry form) and/or maltodextrins having a DE between 10-25.

[0058] The whipping agent according to the present invention is preferably formulated as a powder, which is beneficial for dosing and shelf-life. A preferred way of preparing such a powder is by means of spray drying.

[0059] A second aspect of the present invention relates to a method for preparing a whipping agent as described above. The method used for preparing such a whipping agent comprises the following steps:
  1. i. mixing the proteinaceous emulsifier and carbohydrates with water, such that an aqueous mixture is obtained;
  2. ii. adding the non-palm based edible oil or fat and the non-palm based alpha tending emulsifier to the mixture;
  3. iii. spray drying said mixture, such that a powder is obtained.


[0060] Preferably, before step iii) is carried out, the mixture is homogenized, such that the non-palm based edible oil and other ingredients are evenly mixed trough the mixture and the fat particles have a desired size.

[0061] A third aspect of the present invention relates to an instant edible powder composition comprising the whipping agent as described above and further comprising one or more substances chosen from sugar, milk powder, hydrocolloids, coloring agents, flavoring agents, or a combination thereof. Depending on the intended use, the amount of milk powder, sugar and other agents may vary.

[0062] A fourth aspect of the present invention relates to a method for preparing a whipped topping comprising whipping a whipping agent as described above in a food acceptable liquid, preferably at a temperature between 4°C and 10°C to an overrun of 50-400%.

EXAMPLES



[0067] In the following examples and comparative experiment toppings were prepared from different whipping agents.

Examples 1-4 and comparative experiments 1 and 2


A) Preparation of whipping agent



[0068] In the whipping agents according to the present invention the non-palm based edible (bulk) oil was refined coconut oil (from Cargill, the Netherlands), the proteinaceous emulsifier used was sodium caseinate (EM7, FrieslandCampina DMV), as a carbohydrate source use was made of a dried glucose syrup Glucidex IT 33(Roquette, France). The non-palm based alpha tending emulsifier used was Grindsted Lactem R22, a lactic acid ester of rapeseed oil from DuPont, USA. In the comparative experiment 1, instead of a lactic acid ester of rapeseed oil use was made of a lactic acid ester of palm oil (Grindsted Lactem P22, DuPont). The bulk fat used in the comparative example 2 was non-hydrogenated palm kernel oil (non-HVO palm kernel oil) from Cargill; and the palm based emulsifier was Grindsted Lactem P22 (Dupont).

[0069] The whipping agents referred to above were prepared as follows. First the sodium caseinate and glucose syrup were mixed in a vessel comprising water having a temperature of about 25°C. The coconut oil or the palm kernel oil and the lactic acid ester of rapeseed oil or of palm oil were melted together and added to the aqueous solution. The oil/water mixture thus obtained was stirred, homogenized at about 100 bar at 70°C and subsequently spray dried at approx. 215°C T(in) and approx. 100°C T(out), such that a whipping agent in powder form was obtained. The whipping agents obtained had on a dry weight basis the following composition:

* emulsifier used in examples was a lactic acid ester of rapeseed oil. In the comparative experiments the emulsifier was a lactic acid ester of palm oil.

B) Preparation of whipped products



[0070] The above mentioned whipping agents were used for the preparation of whipped products. This was done by mixing with a mixer (Hobart, model N-50) 30 g of the above mentioned whipping agents, with 250 ml cold, full fat milk. Mixing continued for three minutes at the maximum speed (3).

C) Firmness and overrun



[0071] Of the whipped products prepared above the firmness and overrun were determined. The foam obtained was brought into an overrun cup, with a pre-defined volume and weight. The % overrun was calculated by means of the following formula:

wherein: a = weight of empty cup

b = weight of cup filled with whipped product

d = cup volume



[0072] For determining the firmness use was made of a texture analyzer TA-XT2i of Stable Micro Systems (force required to penetrate the foam), with the following settings: speed 1mm/s, time 25 seconds, measured value: force after 10 seconds penetration cylindrical base (15 gram). The measurement was done in a cup filled with foam and at the latest 5 minutes after the product had been whipped.

[0073] From the results in table 4 it is clear that with the whipping agents according to the present invention it is possible to prepare a whipped product which meets the requirements of a traditional whipped product, prepared with a whipping agent (i.e. palm based) already known in the art. Hence, the inventors have now shown that it is possible to successfully use only non-palm based ingredients in a whipping agent which can be used to prepare e.g. cake fillings, decoration cream etc.
