Description:
Foamable composition and foam

The present invention relates to a foamable composition, a method for producing said foamable composition, a foam, the use of said foamable composition and a food product comprising said foamable composition.

Stabilized gas bubbles in a food matrix build foam, which is often considered as a highly desirable attribute. Such foamed food products provide a unique texture and are commonly used in toppings, icings, mousses, fillings or gravies for desserts, meals or beverages. The benefits of foamed food products relate to softer and smoother texture, enhanced flavour delivery and altered rheology. Therefore, the ability to entrap gas bubbles in a food matrix and the stability of the foam are important in order to provide a pleasing product for the consumer. Common foamed food products are generally formed by bubbling, whipping, shaking or other gas incorporation methods, such as gas injection.

However, further additives are required to stabilize the foam. Surface active agents have commonly been used to stabilize foamed food products. In particular, the products are mainly based on proteins from animal origin and/or fat to provide a whippable emulsion stabilized with various thickeners and emulsifiers for achieving a stable foamy structure with large overrun. Consequently, those products have a long list of ingredients including chemical additives, which are of increased concerns by health-conscious consumers.

Nowadays public interest is focused on nutritional aspects of processed foods such as energy density, fat-free and without cholesterol, as well as absence of potential allergens. The consumer’s demand for healthy nutritional foods that retain the quality of the corresponding traditional formulation has led to the development of a large number of potential fat replacers based on proteins, polyesters, texturizing agents and a variety of other approaches which in turn are loosing acceptance by consumers in today's market who are also looking for fewer additives in products, in an attempt to live healthier lifestyles.

EP-A-1 738 650 relates to aerated food compositions comprising protein, oil, and cyclodextrin. The compositions comprise a significant amount of oil.

US-A-2013/0251879 describes foaming juice compositions, which produce a layer of foam upon the juice product. Said compositions contain a juice product and a food grade additive. FR-A-2 710 501 discloses a fruit-flavoured cream comprising fruit puree, water, sugar, pectin, texturizers and emulsifiers; however, the achieved overrun is not above 150%.

FR-A-2 985 885 relates to foamed food compositions. However, said foamed food compositions contain a stabilizing mixture comprising a modified starch, at least one sucrose ester and xanthan gum and therefore does not meet the consumer’s demands.

EP-A-0274 348 discloses a process for preparing a dietary foam product, which contains fat, proteins and a thickening agent. Again, said compositions contain fat, which does not meet the consumer’s demands.

WO-A-2011/044557 discloses whippable food products containing fat, fiber, protein, emulsifier, sweetener and stabilizer.

US 5,789,004 discloses a stabilizer composition for whipped toppings containing microcrystalline cellulose coprocessed with guar and microcrystalline cellulose coprocessed with carboxymethyl cellulose.

US 5,000,974 relates to low-calorie aerated foods comprising an aeratable fruit base, a hydrocolloid combination of locust-bean flour (gum), pectin, preferably having a degree of esterification between 35 to 38%., carrageenans and emulsifier. The product further has an overrun of 70 to 150%. This concept implies the use of several additives including chemical emulsifiers and carrageenan, all with decreasing acceptance from the customer. Furthermore, the poor thermal stability of carrageenan in acidic conditions limits the application field. Also, a homogenization step is required in the preparation of the food product.

CN 108378296 A discloses a powder comprising various components selected from natural fibers and fruit or vegetable powder. CN 109 123 414 A discloses a similar powder composition comrpising specifically oat fiber and yeast powder. WO 03/0132275 A discloses an Italian dressing. US 2010/173046 A1 discloses a food product, which does not contain germ flour or a thickener.

All of the aerated food product known today contain additives, which do not meet the consumer’s desire of food products originating from plants. In addition, in view of a healthy diet, consumers are increasingly looking for delicious alternatives without allergen, which are fat free and a source of fiber have a low energy content and contain fewer additives. The object of the present invention is therefore to provide a composition having a low fat content, a low energy content, a high overrun and which can provide a source for fiber and form a stable foam having desirable organoleptic characteristics.

Said object is solved by a foamable composition comprising 0.05 to 10 wt% of a plant germ flour, 0.1 to 15 wt% of a thickening agent, 0.1 to 35 wt% of a natural fiber, and water, based on the total weight of the composition. Accordingly the composition of the present invention is typically an aqueous composition.

Surprisingly, the foamable composition in accordance with the present invention has a low fat and energy content, a high overrun and forms a stable foam. In addition, it is a low-energy source of fiber.

Said object is further solved by a foam obtainable from said foamable composition, a method of producing said foamable composition, the use of said foamable composition in a food product and a food product comprising said foamable composition.

According to the specific formulation and available equipment the above steps a) to d) or e) to k) might be carried out in a different order as indicated, although it is preferred to follow the above order.

An important characteristic of the foamable composition according to the invention is the "storability at ambient temperature" for high acid composition as well as for low acid composition. Thus an appropriate thermal treatment to eliminate potential spoilage microorganisms for insuring the product safety and microbiological stability over time during the shelf-life without having a detrimental impact on the organoleptic quality and desired foam performance is required. In this respect a high temperature process with a short holding time in order to provide the commercial sterility of the product shall be adopted.

The temperature and the time may be adjusted according to the given product characteristics based on pH, water activity and specific product formulation within the specific temperature time combination given in the table below. Table 1: Process parameter for UHT and Pasteurization treatment

In a preferred embodiment of the above method in combination with any of the above or below embodiments, in order to obtain the required microbiological sterility, the resulting mixture is heated up to a temperature in the range of 80°C to 105°C, more preferably in the range of 85°C to 98°C for high acid foamable composition and in the range of 120°C to 150°C, more preferably in the range of 125°C to 140°C for low acid foamable composition.

It is remarkable that the above process does not require any homogenization step and thus reduces significantly the required cost for investment, operation as well as for maintenance.

For storage of the foamable composition, the mixture is cooled to a temperature equal to or lower than the maximal aseptic filling temperature. Preferably, the aseptic filling temperature is below 40°C, more preferably below 15°C.

The present invention further provides a method for preparing a foam by using the foamable composition of the present invention, the method comprising the following steps a) dosing a pressurized gas to a pre-determined amount between 2.5 and 3.5 wt% of the foamable composition in a tightly closed container through a valve, b) submitting said gassed foamable composition to an agitation, c) optionally waiting for obtaining partly a partial pressure equilibrium between the gassed mixture and the head space volume, and d) dispensing said pressurized cold composition through a valve of the container in head down position by gently actuating the lever in order to obtain a foamed food product with an overrun larger than 350%.

In a preferred embodiment in combination with any of the above or below embodiments, the gassed mixture of step a) is subjected to agitation until a partial pressure equilibrium between the gassed mixture and the head space volume is obtained. In a further preferred embodiment in combination with any of the above or below embodiments, the pressure of the pressurized gas in step g) is 10 to 20 x 10 5 Pa, more preferably 14 to 18 x 10 5 Pa.

The present invention further relates to a foam. In a preferred embodiment in combination with any of the above or below embodiments, the foam comprises an aqueous continuous phase of from 9 to 22 vol% and a gaseous phase from 78 to 91 vol%. The overrun of the foam is preferably from 3.5 to 10, i.e. 350 to 1000%. .

In a further preferred embodiment in combination with any of the above or below embodiments, the gaseous phase is a gas selected from air, nitrogen, carbon dioxide, nitrous oxide, helium, oxygen and mixtures thereof. More preferably, the gas is selected from nitrogen, nitrous oxide, carbon dioxide and mixtures thereof.

Accordingly, the present invention also provides aressurized container, comprising the foamable composition in accordance with any one of claims 1 to 10 and a pressurized gas at a pressure of from 10 to 30 x 10 5 Pa.

Preferably, the pressurized gas is selected among air, nitrogen, carbon dioxide, nitrous oxide, helium, oxygen and mixtures thereof.

Such a pressurized container may comprise a valve allowing to introduce the pressurized gas and an opening for dispensing the foamed composition.

In another preferred embodiment in combination with any of the above or below embodiments, the foam has a caloric density of less than 4 kJ/ml, more preferably less than 2 kJ/ml, particularly preferably less than 0.8 kJ/ml.

The foam of the present invention has an overrun of 350 to 1000% and is stable during storage at a temperature of 20 to 80 °C for at least 30 minutes.

Foams created with such formulations have an enhanced overrun and are surprisingly stable and versatile even when applied to acidic or hot food.

In a further preferred embodiment in combination with any of the above or below embodiments, the foamable composition of the present invention can be placed in a ready-to-use pressurized aseptic container, such as an aerosol can with a dispensing device. Alternatively, the foamable composition of the present invention can be placed in a non-pressurized aseptic packaging, and the foamable composition is dosed at the point of use in a container adequate to be pressurized with a controlled quantity of gas.

When the dispenser's valve is slowly pressed, the mixture is expelled through the orifices by the high pressure inside. The change in pressure causes some of the dissolved gas to return to bubbles, effectively fluffing up the composition, producing small bubbles surrounded by a flexible, relatively stable film. The volume extension is considered as a key characteristic of foamable composition and is usually defined as “overrun”.

Overrun refers to the volume of gas added to the foamable composition and it quantifies the foaming capacity of the composition. The overrun is measured according to following equation: (weight of 100 ml foamable composition - weight of 100 ml foamed composition) c 100 / (weight of 100 ml foamed composition). Alternatively following equation based on the volume can also be

USed. Overrun = 100% x (Vfoamed composition Vfoamable composition) / Vfoamable composition- It IS alSO reported as a percentage value.

The disclosed compositions and uses of the present invention are such that they have an overrun of at least 350%.

In this regard, the foams obtained in accordance with the present invention do show a viscosity recovery behavior. This means that during the dispensing process the foamed composition displays a highly satisfactory flow property, so that dispensing can proceed without problem. Once dispensed, however, the viscosity of the foam increases again to a level that in particular the shape of the dispensed foam can be retained for a desired period of time. The foam accordingly is stable, as described herein.

For the practice, however, foam capacity is only relevant if the stability of the foam is also given, to allow for preparing, serving and tasting the foamed product within reasonable time.

The foam stability is influenced by other intrinsic properties from the foamable composition as those impacting the foaming capacity. Therefore the foam stability is also a key performance indicator to be determined. The foam stability has been measured as the relative change in the foam height in a cup at ambient temperature over time.

In certain embodiments, the foam maintains at least about 80% of its height after 60 minutes. In further preferred embodiments, the foam maintains at least about 90% of its height after 60 minutes. In certain embodiments, the foam maintains at least about 60% of its height on a food with a serving temperature above 50°C after 30 minutes. Also of interest for evaluating foamable composition, is the syneresis build over time. The syneresis has been measured as the weight of the liquid collected at the bottom of the cup at the end of the stability test. The liquid has been pipeted with a micropipette and the collected volume weight on precision balance. The syneresis is measured in g.

Finally, as for any food product the sensoric is a key and the evaluation has been done using a score range from 5 (very good) to 1 (not acceptable). The sensoric evaluation is holistic and includes the stability, the mouthfeel, the taste and the color of the foamable product.

In a preferred embodiment in combination with any of the above or below embodiments, the sweet, spicy or salty foam is a dish on its own, a topping, a filling, a decoration, a seasoning / condiment, or an ingredient for an appetizer, entree, soup, main course meal, side dish, cheese, dessert, bakery, confectionary or any other food or beverage where foam is desirable.
