METHOD FOR PRODUCING EMULSIFIED EXTRACTED SOLUTION AND INSOLUBLE DIETARY FIBER OBTAINED FROM SOYBEAN CURD REFUSE AND SEPARATION METHOD

摘要

PPROBLEM TO BE SOLVED: To rapidly separate an extracted solution characterized in an emulsified state and an insoluble dietary fiber obtained from its residue from a soybean curd refuse, to obtain products having additional values from them and to reduce a cost required for the treatment of a soybean curd refuse. PSOLUTION: The protein of a soybean curd refuse is decomposed and hydrolyzed by using an enzyme to give an extracted solution which comprises a peptide, an amino acid, a simultaneously extracted water-soluble dietary fiber, a carbohydrate and a lipid and is characterized in an emulsified state. The residue of an insoluble dietary fiber is immersed in an alkali solution or an acid solution, the enzyme, the protein, the carbohydrate and the lipid not extracted by heating are removed and the obtained insoluble dietary fiber is rapidly separated. The extracted solution is useful as an antifoaming agent during processing of a health food and a food, a burning inhibitor, an emulsion stabilizer, a humectant for a cosmetic, etc. The insoluble fiber is useful in a wide field as an extender for various foods and a diet food because of being white and tasteless, mixed with a paper product such as corrugated board, etc., and used.
