PROCESS FOR PRODUCING WATER-SOLUBLE VEGETABLE FIBER, AND BIODEGRADABLE FILM, SIZING AGENT, CHEWING GUM AND LOW-CALORIE FOOD OBTAINED FROM SAID FIBER

摘要

A process for producing a water-soluble vegetable fiber from a water-insoluble vegetable fiber containing a protein in a high yield with only a reduced extent of contamination with the protein and amino acids formed by the hydrolysis thereof, which comprises hydrolyzing the water-insoluble fiber below 130 DEG C under an acidic condition near the isoelectric point of the protein.
