Biotechnological method for obtaining dietary fiber from bran of grain crops

Abstract

This article substantiates the relevance of the development of a biotechnological method for obtaining dietary fibers from the bran of grain crops. Bran of grain crops were selected as objects of research: wheat, rye and oats. In this work, an enzymatic method of processing wheat bran was chosen. Α-amylase was chosen as the enzyme.Based on the conducted research, a biotechnological method for obtaining dietary fiber concentrate from wheat bran has been developed. The α-amylase enzyme was selected for the fermentation process.It was found that the fermentation process at a temperature from 60 to 65 ° C and a pH value in the range from 5 to 7, lasting 18-20 hours, allowed to obtain a dry concentrate of dietary fibers with a total content of 69.7% in the finished product.
