摘要： The present invention is to provide a method for obtaining more efficiently isolated-soy protein, which has excellent gelation properties and shows neither bitterness nor astringency characteristic to soybean, while reducing the amount of water used in a soy protein manufacturing plant and thus lessening burden on the environment owing to the reduction in discharged water. It is a method for producing isolated-soy protein, including: an acid-washing step of washing defatted soybeans with an aqueous medium in a region of pH 3.0 to 5.0 to extract and remove whey components; an extraction step of extracting protein from acid-washed soybean slurry obtained in the acid-washing step with an aqueous medium in a neutral to alkaline region and then removing an extraction residue; and an isolation step of separating the extract solution obtained in the extraction step into water and protein while holding it in the neutral to alkaline region.

摘要： The object is to provide a soybean protein hydrolyzate which can be produced by hydrolysis of a soybean protein produced by “method B” as defined in the description and produces no dreg even when refrigerated under acidic conditions, particularly a soybean peptide mixture having a relatively low molecular weight. Disclosed is a method for production of a soybean peptide mixture, comprising the steps of: (a) extracting a concentrated soybean protein with water to yield an extract; (b) treating the extract with a protease under alkaline to neutral conditions; (c) further treating the resulting product with a protease under acidic conditions; (d) treating the resulting product with a phytic acid (phytase)-decomposing enzyme; and (e) separating and removing an insoluble material from the product.
