Abstract

A dietary fiber material obtained by using enzymes to digest cereal grains. The enzymes substantially hydrolyze any starch occurring in the cereal grain into small molecules but only partially hydrolyze β-glucan molecules. The dietary fiber material can have excellent physicochemical, physiological, and sensory properties such as low molecular weight, a particular molecular weight distribution, and a particular polydispersity, in addition to having excellent food ingredient properties. As a food ingredient, the material can have high β-glucan content which provides nutrient to the body. Because the dietary fiber material can have neutral mouthfeel, it can be used to enhance the nutritional content of ice cream, yogurt, baked goods, bars, beverages, or certain other foods—without affecting the taste or other sensory attributes of the food. As a further benefit, the dietary fiber material can be used to provide certain therapeutic benefits, such as anticholesterol activity.

First claim

1 . A dietary fiber composition isolated from a cereal grain containing β-glucan, comprising:
a β-glucan compound having a weight average molecular weight ranging from about 50 kDa to about 1000 kDa, wherein said β-glucan compound is a modified form of a cereal β-glucan; and,
wherein a 1% mixture by weight of said dietary fiber composition and water is stable and has a viscosity of about 1500 cps or less.

2 .- 25 . (canceled)

26 . A process for reducing the molecular weight of a cereal β-glucan, comprising: using a first enzyme or first combination of enzymes to perform a non-specific digestion of polysaccharides found in a cereal, wherein the polysaccharides include β-glucan having a weight average molecular weight and starch, and wherein the non-specific digestion reduces the weight average molecular weight of the β-glucan to a reduced weight average molecular weight and breaks down the starch.

27 .- 31 . (canceled)

32 . A composition, comprising: a β-glucan composition in amount sufficient to lower LDL-C, wherein said β-glucan composition comprises a β-glucan compound having a weight average molecular weight less than or equal to about 200 kDA, and wherein said β-glucan composition has a viscosity less than or equal to about 100 cps, and a 1% mixture by weight of said dietary fiber composition and water is stable and has a viscosity of about 1500 cps or less.

33 . A method for obtaining a dietary fiber containing material, comprising:
forming an aqueous mixture having components which comprise a first exogenous enzyme, a second exogenous enzyme, and one or more cereal grains; wherein the one or more cereal grains comprise β-glucan and starch; cleaving by a first hydrolysis reaction catalyzed by the first exogenous enzyme at least some of the bonds of the β-glucan, wherein the average molecular weight of the β-glucan is reduced; and cleaving by a second hydrolysis reaction catalyzed by the second exogenous enzyme at least some of the bonds of the starch; separating and isolating a portion of the mixture, wherein the separated portion contains at least some of the β-glucan; purifying the β-glucan within the separated portion; obtaining a dietary fiber containing material; wherein the dietary fiber containing material comprises greater than 40 percent β-glucan; and the average molecular weight of the β-glucan within the dietary fiber containing material is less than 400,000 daltons.
