Abstract
The present invention relates to an improved process for producing a beta-glucanase treated water-soluble dietary fiber composition wherein an aqueous dispersion of a gelatinized, milled, beta-glucan containing grain-based substrate is treated with an alpha-amylase under conditions which will hydrolyze said substrate and yield a soluble fraction and an insoluble fraction, separating said soluble fraction from said insoluble fraction, and recovering from said soluble fraction said water-soluble dietary fiber substantially free of water-insoluble fiber, wherein the improvement comprises treating beta-glucans released from the grain-based substrate with beta-glucanase, wherein the weight ratio of beta-glucanase to initial beta-glucan containing substrate is in the range of from about 4.times.10.sup.-6 :1 to about 2.times.10.sup.-2:1 (beta-glucanase:grain-based substrate), and wherein the treatment of the beta-glucans with the beta-glucanase is carried out at a temperature in the range of from about 30.degree. C. to about 60.degree. C., for a period of time in the range of from about 5 to about 120 minutes, and at a pH in the range of from about 5 to about 7. The present invention furt…
