| 摘要 |
The present invention relates to an improved process for producing a water-soluble dietary fiber composition wherein an aqueous dispersion of a gelatinized, milled, beta-glucan containing grain-based substrate is treated with alpha-amylase under conditions which will hydrolyze the substrate and yield a soluble fraction and an insoluble fraction, said soluble fraction is separated from said insoluble fraction, and said water-soluble dietary fiber is recovered from said soluble fraction substantially free of water-insoluble fiber, wherein the improvement to such process comprises treating beta-glucans released from the grain-based substrate with beta-glucanase under conditions which will hydrolyze the beta-glucans. The present invention further comprises dietary fiber compositions produced by the above-described process and a method of preparing edible food compositions containing the dietary fiber compositions produced by the above-described process. |
