PROCESSED SOYBEAN AND PRODUCTION THEREOF

摘要

PURPOSE:To obtain processed soybeans suitable as diet for renopathy, by dipping soybeans in an acidic aqueous solution and eluting phosphorus and potassium components in the soybeans in the above-mentioned aqueous solution to reduce the contents of the phosphorus and potassium. CONSTITUTION:Soybeans are dipped in an aqueous solution at 3.0-6.5pH to elute phosphorus and potassium components in the soybeans in the above- mentioned aqueous solution. Thereby the contents of the phosphorus and potassium in the soybeans are respectively reduced by >=30%, preferably >=70% (preferably <=11mg phosphorus content and <=40mg potassium content based on 1g protein in the soybean) to afford the aimed processed soybeans. The soybeans are preferably defatted soybeans.
