Description

BACKGROUND OF THE INVENTION

The present invention is directed to low calorie fat substitutes. More specifically, it is directed to an emulsion containing an oil phase and an aqueous phase which is useful as a low calorie fat substitute.

In today's health conscious society, there is a growing demand for low calorie foods. Excess body weight not only creates a feeling of low self confidence in social situations but also has been shown to contribute to the impairment of the cardiovascular function of the individual. Moreover, the reduction of the performance capacity of the individual is another consequence of excess body weight.

Many approaches have been suggested to control excess body weight. The use of chemical appetite suppressants and appetite inhibitors is a well known approach but these chemical agents are often unsafe for long term use and/or may have undesirable side effects. Moreover, they are usually available only through a physician's prescription.

Low calorie foods have also been widely advocated as a diet regimen to control excess body weight. Such low-calorie foods include low calorie spreads, which are typically water-in-oil emulsions; and low calorie sauces, such as salad dressings and mayonnaise which are typically oil-in-water emulsions.

DETAILED DESCRIPTION OF THE INVENTION

The aqueous gel-forming compositions used in the present invention are formed by dissolving a gel-forming composition in an aqueous medium. Examples of gel-forming compositions are agar, carrageenans, gelatin, and pectins. The amount of the gel-forming composition to be dissolved in the aqueous medium to form the aqueous gel-forming composition is readily determined by a person of ordinary skill in the art.

Preferred also is the aqueous gel-forming composition formed by combining, in an aqueous medium, a gel-forming amount of an appropriate polysaccharide with a salt of a metal cation capable of cross-linking said polysaccharide. Preferred metal cations are food grade metal cations. Preferred aqueous gel-forming compositions are those wherein the gel-forming polysaccharide is selected from the group consisting of alginates, succinoglycans, carrageenans, xanthans, and scleroglucans, and the metal cation is calcium (II) or magnesium (II). Another preferred aqueous gel-forming composition is that wherein the gel-forming polysaccharide is carrageenan and the metal cation is calcium (II) or potassium (I). Another preferred gel-forming composition is formed by combining a xanthan with locust bean gum or guar gum.

The gel-forming composition is present, based on the weight of the aqueous phase, at from about 0.1 to about 3.0 percent of the aqueous phase. As is well known to one skilled in the art, the amount of gel-forming composition necessary to render the aqueous phase non-flowable depends on the nature of the gel-forming composition. Thus, the above ranges are subject to variations depending on the gel-forming composition used. For instance, if agar is used, it will be present in the aqueous phase at a concentration of from about 0.3 to about 0.7 percent. If carrageenan is used, it will be present in the aqueous phase at a concentration of from about 0.7 to about 2.0 percent. If cross-linked carrageenan is used, it will be present in the aqueous phase at a concentration of from about 0.3 to about 1.5 percent. If cross-linked alginate is used, it will be present in the aqueous phase at a concentration of from about 0.5 to about 1.5 percent.

Another suitable gel-forming composition is formed by adding an acidifying agent to an alginate. Suitable acidifying agents include acids such as hydrochloric, acetic, citric, phosphoric, fumaric, tartaric and succinic acid.

The emulsion also contains an emulsifier. Preferred commercially available emulsifiers are lecithins, mono- and diglycerides, diacetyltartaric acid esters of mono- and diglycerides, monosodium phosphate derivatives of mono- and diglycerides, polyol fatty acid esters, sorbitan fatty acid esters, polyoxyethylene mono- and diglycerides, polyoxyethylene sorbitan fatty acid esters, sucrose fatty acid esters, esters of acids selected from the group consisting of fumaric, lactic, tartaric, and citric acid with fatty acids or fatty alcohols, esters of acids selected from the group consisting of of fumaric, lactic, tartaric, citric, acetic and succinic with mono- or diglycerides; and combinations thereof.

The oil phase of the emulsion also contains, based on the weight of the total emulsion, from about 5 to about 99 percent, preferably from about 15 to about 50 percent, of an edible fat or oil. Suitable fats and oils include animal fats, vegetable fats and oils, anhydrous milkfat, hydrogenated vegetable oils, partially hydrogenated vegetable oils, partially hydrogenated palm kernel oils; and combinations thereof.

The pH of the emulsion may, if desired, be controlled by addition of one or more pH adjusting agents. Suitable pH adjusting agents are added at a concentration of from about 0.1 to about 3.0 percent, preferably 0.1-1.0 percent, based on the weight of the emulsion. Examples of pH adjusting agents are fumaric, hydrochloric, sulfuric, phosphoric, acetic, lactic, adipic, malic, tartaric or citric acid; salts thereof; glucono delta lactone; and combinations thereof.

The emulsion of the present invention contains an aqueous phase which is rendered non-flowable by the addition of a gel-forming composition. By "non-flowable" is meant that if the aqueous phase were made up separately, apart from the emulsion, it would not flow or conform to its container in the manner of a liquid. Although the aqueous phase is non-flowable, the interaction between the aqueous phase and the oil phase results in the emulsion being pourable. By "pourable" is meant that the emulsion retains substantially liquid characteristics, and can easily be transferred from one container to another by pouring.

For incorporation of either the pourable or the nonpourable emulsion of the present invention into a foodstuff which does not contain a large amount of water, it may be desirable to add a water-binding composition to the emulsion to decrease the water activity of the aqueous phase. This serves to decrease osmotic effects, whereby water is lost from the emulsion to other components of the foodstuff, thus possibly destabilizing the emulsion. As is well known to those skilled in the art, decreasing the water activity of the aqueous phase can have the further beneficial effect of decreasing susceptibility of the emulsion to microbial growth.

As used herein the term "water-binding composition" is defined as a substance which, when combined with water, decreases the availability of the water for physical, chemical, or metabolic processes.

Non-limiting examples of such water-binding compositions include soluble carbohydrates (e.g. sucrose, polydextrose), insoluble carbohydrates (e.g. microcrystalline cellulose, micronized bran), polyols (e.g. sorbitol, glycerol), proteins (e.g. whey protein), inorganic salts (e.g. sodium chloride), carboxylic acids (e.g. citric aid), salts of carboxylic acids (e.g. sodium acetate); and combinations thereof.

Emulsions of the present invention are useful as fat substitutes, replacing at least a portion of the normally present triglycerides in a foodstuff. Some emulsions of the present invention can be substituted for triglycerides on a substantially equal weight basis. Other emulsions with lower water content, also within the scope of the present invention, are useful as concentrated fat substitutes. Because of their low water content, such emulsions can be shipped and stored economically, and have improved microbiological stability. During formulation of a food with a concentrated emulsion, water is added to the emulsion either before or during addition of other food ingredients.

Preferred foods into which the present emulsion may be incorporated are salad dressings, frozen desserts, soups, dips for chips, crackers or vegetables, mayonnaise, fillings for cakes and cookies, confections, cake frosting, whipped desserts, gelled desserts, beverages, puddings, and baked goods.

The emulsion of the present invention is prepared by mixing an aqueous medium, a gel-forming composition, a fat or oil, and an appropriate emulsifier, stirring at a temperature and shear rate sufficient to produce an emulsion, and then cooling the resultant emulsion. If the gel-forming composition includes a cross-linking agent or gelation promoter, this is preferably added to the stirred emulsion prior to cooling.

The same process can be used to prepare a nonpourable emulsion, also useful as a low-calorie fat substitute. While it is not intended that the scope of the invention be limited by any particular theory, the following observations appear to apply in most cases: (1) only fats which are solid or semisolid at room temperature give nonpourable emulsions. (2) Decreasing the plasticity of the fat increases emulsion viscosity. (3) Increasing the percentage of fat in the emulsion increases emulsion viscosity; emulsions containing more than about 50% of solid or semisolid fat are usually nonpourable. (4) Increasing gelant concentration increases emulsion viscosity. Further, it has been observed that either homogenization or an increase in emulsifier level usually, although not always, increases emulsion viscosity.

In either concentrated or non-concentrated form, the nonpourable emulsion of the present invention can be used to replace at least a portion of the normally present triglycerides in a foodstuff, and is useful in the same foods as the pourable emulsion. The nonpourable emulsion sometimes shows better functionality than the pourable emulsion in foods which are themselves highly viscous and have a high fat content, such as cookie fillings and certain frostings for cakes or cookies.

The invention having been described in general terms, reference is now made to specific examples. It is to be understood that these examples are not meant to limit the present invention, the scope of which is determined by the appended claims.
