Summary

AN INVESTIGATION WAS MADE OF THE ROLE OF PROTEINASES OF PSYCHROTROPHIC ORIGIN, IN THE PRODUCTION OF PROTEOSE-PEPTONE, DURING REFRIGERATED STORAGE OF MILK. THE PROTEOSE-PEPTONE INCREASE APPEARED TO BE PROPORTIONAL TO THE GROWTH OF PSYCHROTROPHS ; IT IS SIGNIFICANT FOR A BACTERIAL COUNT OF 1 MILLION CFU/ML. ELECTROPHORESIS AND GEL FILTRATION REVEAL THAT THE MAJOR COMPONENTS OF THE PROTEOSE-PEPTONE FRACTION TEND TO DISAPPEAR AFTER 3 DAYS OF STORAGE ; PEPTIDES WITH HIGH ELECTROPHORETIC MOBILITY AND LOW MOLECULAR WEIGHT THEN APPEAR.
