Fiber and Dietary Fiber

Dietary fiber

Dietary fiber is plant-derived material that is resistant to digestion by human alimentary enzymes. Fiber may be divided into two broad chemical classes: 7) non-a-glucan polysaccharides (cellulose, hemicelluloses, and pectins) and 2) lignins. Dietary fiber behaves within the gastrointestinal tract as a polymer matrix with variable physicochemical properties including susceptibility to bacterial...

Saccharification of Okara fiber by plant dietary fiber hydrolases.

In this paper, the saccharification process of okara fiber with pectinase, xylanase and cellulase was investigated as a preliminary attempt to effectively utilize okara fiber. The solubilization of okara fiber was raised in proportion to the number of enzymes used; that is, by a single enzyme, two enzymes and three enzymes, in that order. The saccharification of okara fiber was much more comple...
