COMPOSITION AMD METHOD FOR PREPARING REDUCED FAT FOOD PRODUCTS
BACKGROUND OF THE INVENTION
Field of the Invention
This invention relates generally to foods and ingredient for foods, and more particularly to compositions and methods fo preparing reduced fat food products. Description of the Relevant Art Concerns over the adverse health effects of dietar unsaturated fats have created a demand for reduced fat foo products. Fats impart a number of qualities to foods, includin taste, texture, and consistency. It is desirable that reduced fat food products maintain as much and as many of these qualitie as possible. It is also desirable that fat-reducing composition have a satisfactory shelf life, and have physical characteristic which will permit use in a variety of food products with variety of different ingredients.
The water activity (aw) is a measure of the free wate available in a food product. The water activity is significan in the food industry because microbial spoilage is facilitate at higher water activities, and retarded at lower wate activities. Bacteria generally do not survive where the aw i .85 or less. Molds do not survive well at an aw of .75 or below, except for one or two varieties which can survive to an aw o about .70. Some yeasts have been found which can survive to a aw levels of around .62, but most are unable to survive below a aw of about .75. It is therefore desirable to produce foo products with as low an aw as possible. Efforts to lower the aw, however, can have a deleterious effect on the eating quality o the resulting food product.
SUMMARY OF THE INVENTION It is an object of the invention to provide a method an composition for preparing reduced fat food products which wil have acceptable taste characteristics. It is another object of the invention to provide a metho and composition for preparing reduced fat food products whic will have acceptable texture characteristics.
It is still another object of the invention to provide method and composition for preparing reduced fat food product which will have an acceptable consistency.
It is yet another object of the invention to provide method and composition for preparing reduced fat food product which can be utilized to create a variety of different foo products. It is another object of the invention to provide a metho and composition for preparing reduced fat food products whic will have a relatively low aw.
These and other objects are provided by a method an composition for preparing reduced fat food products in which a edible viscous liquid is provided with a liquid humectant, starch, and a fiber. The edible viscous liquid is mos preferably high fructose corn syrup. The liquid humectant i most preferably glycerin. The starch and fiber can be selecte from a number suitable products. A preferred composition is based upon 100 parts by weigh of edible viscous liquid. The liquid humectant is preferabl present in an amount between about 10-50 parts by weight. Th starch is preferably present in an amount between about 5-2 parts by weight. The fiber is preferably present in an amoun between about 1-15 parts by weight.
An emulsifier can be provided in compositions according t the invention. The emulsifier, if present, is preferabl provided in amounts up to about 10 parts by weight of the above described composition. Lecithin can also be included, and i preferably provided in amounts up to about 10 parts by weight.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The proportions of the edible viscous liquid, liquid humectant, starch and fiber components of the invention can vary. Different foods having different ingredients and product characteristics, and made according to different processes and at different temperatures, may require adjustments to the proportions. Such would largely be determined on an empirical basis for the proportions that yield the most desirable product.
The following preferred component ranges are based upon 100 parts by weight of edible viscous liquid. The invention preferably comprises between about 10-50 parts by weight of liquid humectant, between about 5-25 parts by weight of starch, and between about 1-15 parts by weight of fiber. The invention can include additional components. An emulsifier can be provided. The emulsifier is preferably provided in amounts up to about 10 parts by weight of the above-described composition. Lecithin can also be provided, preferably in amounts up to about 10 parts by weight. Flavoring agents can be added to the above composition, if desired. Edible viscous liquids suitable for the invention include, but are not limited to, high fructose corn syrup, sucrose solutions, invert syrup, sucrose syrup, honey, molasses, and mixtures thereof. A currently preferred edible viscous liquid is high fructose corn syrup (HFCS) . A number of varieties of high fructose corn syrup products are available, and are sometimes classified by the percentage of solids in the syrup. Corn syrups having 40%-90% solids are presently preferred.
Examples of suitable humectants include, but are not limited to, glycerin, 1, 3-butylene glycol, mannitol, propylene glycol, sodium lactate, sorbitol, and mixtures thereof. Corn sweeteners such as corn syrup, as well as other products, can also function as suitable humectants. Glycerin is a currently preferred liquid humectant.
Starches suitable for use in the invention can be selected from a variety of sources. These include, but are not limited
to, arrowroot, corn, high amylose, pea, potato, rice, tapioca, waxy maize, wheat, and mixtures thereof.
Fibers suitable for the invention include, but are not limited to, amaranth bran, apple, barley, cellulose, citrus, cocoa bran, corn bran, fruit (low moisture) , multigrain, mustard, oat bran, pea bran, peanut bran, pear, psyllium, rice bran, soy bran, sugar beet, sunflower, tomato, vegetable, wheat bran, and mixtures thereof.
Emulsifiers suitable for use with the invention can be selected from a number of known edible emulsifiers. Suitable emulsifiers include, but are not limited to, lecithin, acetylated monoglycerides, glycerol esters, mono-glycerides and di- glycerides, polyglycerol esters, propylene glycol esters, polyoxyethylene sorbitan esters, sorbitan esters, sodium citrate, sodium lactate, sodium stearoyl-2-lactylate, stearyl-2-lactylic acid, and mixtures thereof. Lecithin is a currently preferred emulsifier. Hydrates are preferable where possible.

In some circumstances, the product of the invention may be used as a fat substitute for all of the fat in the food product.
The invention can be embodied in a host of different products having widely different food characteristics. Accordingly, it is anticipated that modifications to the proportions and ingredients set forth herein will sometimes be necessary to adapt the invention to a particular product. This invention can be embodied in other specific forms without departing from the spirit or essential attributes thereof, and accordingly, reference should be had to the following claims, rather than to the foregoing specification, as indicating the scope of the invention.
