Abstract
Abstract THE INVENTION ENTAILS AN IMPROVED PROCESS FOR PREPARING BLAND FISH PROTEIN CONCENTRATE BY BOILING WHOLE FROZEN OR FRESH FISH TO SEPARATE THE FLESH FROM THE BONE, AND REMOVING THE OILS FROM THE WATER SURFACE GENERATED DURING BOILING. THE SLURRY IS THEN ACIDIFIED TO SUPRESS PROTEIN SOLUBILITY AND THE MIXTURE IS GROUND OR COMMINUTED SO AS TO SUBSTANTIALLY RETAIN THE BONES AT ORIGINAL SIZE, WHEREUPON THE SLURRY IS SCREENED TO REMOVE WATER AND FINE SOLDS. THE MIXTURE IS THEN EXTRACTED WITH A BLAND SOLVENT AND DRIED TO A BLAND PROTEIN CONCENTRATE. DEBONING MAY OCCUR AFTER BOILING, AFTER ACIDIFICATION OR AFTER DRYING.
