    • Abstract

       

      The possibility of utilisation of a low priced catfish known as freshwater shark (Wallago attu) for the production of cheap and widely acceptable form of protein concentrate (FPC) has been studied. The fish could be converted into a product having good dispersible and better functional qualities of protein by solvent-extraction and other process techniques. Conventional processing was found to be improved by washing the fish in brine and initial steaming operation. Both steaming and use of brine during blending gave good appearance of the product. Slight hydrolysis with enzyme pepsin produced better foaming and required dispersion. The treatment with acetic acid resulted in a good swelling effect of the FPC.
