Study on Soybean Polypeptide Refining Process

Abstract:

Soybean polypeptide mixture was decolorized by adopting activated carbon adsorption decolourization process. Anion/cation exchange process was used in the desalination processing of soybean polypeptide. It was showed that excellent decolorizing and desalting effect to soybean peptide solution was gained in the decolourization and desalination process adopted in this experiment. Optimal dosage of activated carbon was 1.2% solution amount (w/w). After decolorizing soybean polypeptide solution color was yellow. Proportion of anion resin and cation resin of ion exchange resin was 2:3(V/V). The volume of solution processed was 5 times as the volume of anion exchange resin. After desalination processing, ash content of soybean peptide solution reduced to 2.11% (dry basis), salinity decreased by 86%, on the other hand taste of soybean polypeptide was lite.
