METHOD FOR PRODUCING DECOMPOSITION PRODUCT OF SOYBEAN CURD REFUSE

摘要

PROBLEM TO BE SOLVED: To obtain a new material useful as a water-soluble dietary fiber material or a protein-suspending agent using water-insoluble soybean curd refuse as the raw material. SOLUTION: The objective method for producing a water-soluble decomposition product of soybean curd refuse comprises contacting water-insoluble soybean curd refuse derived from soybeans with high temperature and pressure water at a temperature of >100 deg.C to 300 deg.C and having a pressure higher than the vapor pressure of water at the temperature for a time required for producing a water-soluble soybean curd refuse decomposition product with a mass of 100 kDa to 1,000 kDa to be produced, and then partially decomposing the resultant product. The water-soluble decomposition product of soybean curd refuse is obtained by this method.
