Method of treating soy proteins and soy protein product produced by this method

摘要

A method of treating a proteinaceous material having a first concentration of beta-conglycinin, the method including combining the proteinaceous material with an enzyme to form a reaction mixture, the reaction mixture initially having a pH of at least about 7.0 standard pH units, allowing the enzyme to hydrolyze beta-conglycinin present in the reaction mixture to form a proteinaceous intermediate, and inactivating the enzyme present in the reaction mixture after a reaction period to form a proteinaceous product, the proteinaceous product having a second concentration of beta-conglycinin, the second concentration of beta-conglycinin being at least 99 percent less than the first concentration of beta-conglycinin.
