Abstract
A novel low-carbohydrate digestible hydrocolloidal composition is separated from a cereal-based substrate by means of a specific sequence of steps for treating an aqueous slurry of the substrate. These all-natural compositions are low in digestible carbohydrates, principally starches, and rich in soluble fiber, principally β-glucan, as well as proteins. The hydrocolloidal products are recovered in high yields, are smooth in texture, have unexpected thickening properties, have a bland flavor, and are useful for texturizing food, especially bakery products. These hydrocolloidal products can also be used as food ingredients for increasing the nutritional level of foods and supplements.
Claims21
A thermo-sheared soluble hydrocolloid comprising a ratio of digestible starch to β-glucan soluble fiber in the range of 0.1-2.0.
A method for preparing a thermo-sheared soluble hydrocolloid comprising a ratio of digestible starch to β-glucan soluble fiber in the range of 0.1-2.0, wherein said digestible starch is gelatinized and the β-glucan consists essentially of solubilized β-glucan, the method comprising the steps:
- a. subjecting a first aqueous slurry of a cereal substrate to a temperature in the range of about 20-60° C. under conditions of shear sufficient to disrupt the cellular structure of said substrate, thereby yielding a sheared, second aqueous slurry;
- b. separating the sheared, second aqueous slurry resulting from (a) into a first liquid fraction comprising starch and a first solid fraction comprising fiber;
- c. separating starch from said first liquid fraction to yield a starch-depleted liquid;
- d. recombining said starch-depleted liquid with said first solid fraction to yield a third aqueous slurry;
- and
- e. recovering said hydrocolloid from said third aqueous slurry.
