Insolubilization of Water-Soluble Protein by Electrolytic Treatment

Abstract

An aqueous solution containing water-soluble protein of Alaska pollack was electrolytically treated in both separated and non-separated type vessels, and the rate of insolubilization of water-soluble protein was measured. In the separated type vessel, the rate of insolubilization showed a characteristic pattern, which had a time lag followed by a region of constant rate. This constant rate of insolubilization was found to be roughly proportional to current but independent of potential. The rate of insolubilization in the non-separated type vessel was much smaller than that in the separated type vessel. The insolubilization of water-soluble protein caused by electrolytic treatment seemed to be due mainly to the isoelectric aggregation in the positive side vessel.
