Summary

STORAGE OF BEEF AND PORK MUSCLES AT 277 K (4 DEG C) ALTERS THE ISOELECTRIC FOCUSING (PAGIF) BAND PATTERN OF SARCOPLASMIC PROTEINS, THIS BEING THE RESULT OF PROTEOLYTIC BREAKDOWN PROCESSES DURING WHICH PROTEIN BANDS ARE WEAKENED AND NEW BANDS (FRAGMENTS) ARE FORMED. THE POSITION OF MYOGLOBIN BANDS WAS UNAFFECTED. MUSCLES FROM CATTLE, PIGS AND HORSES WERE COMPARED AFTER FREEZE-DRYING, THE BAND PATTERNS SHOWED NO QUALITATIVE CHANGES AS COMPARED WITH FRESH SAMPLES. FREEZE-DRIED PREPARATIONS OF ISOLATED PROTEINS HAD THE SAME BAND PATTERN AFTER 15 YEARS AT 277 K AS FRESHLY PREPARED SAMPLES. G.R.S.
