EFFECTS OF TREATMENT WITH INTRAPERITONEAL INJECTIONS OF CALCIUM GLUCONATE AND MAGNESIUM SULPHATE ON TENDERNESS OF FROZEN LAMB.

Author(s) : GARCIA MATAMOROS E., MORAL A., JIMENEZ COLMENERO F.

Summary

INTRAPERITONEAL INJECTIONS OF CALCIUM GLUCONATE AND MAGNESIUM SULPHATE WERE APPLIED TO A NUMBER OF LAMB. AFTER RAPID COOLING OF THE CARCASSES THEY WERE CUT INTO PIECES, FROZEN AT 238 TO 233 K (-35 TO -40 C) AND THE LEGS AND CHOPS WERE THEN WRAPPED IN ALUMINIUM FOIL AND STORED AT 253 K (-20 C) FOR A PERIOD OF 18 MONTHS. FOR EACH LOT, QUALITY CONTROL TESTS WERE MADE PERIODICALLY ON THE MINCED MUSCLES OF EACH PORTION. THE PH, GLYCOGEN AND LACTIC ACID VALUES DECREASED THROUGHOUT THE STORAGE TIME ; THE FREE WATER AND FIRMESS VALUES SHOWED A SIGNIFICANT PERCENTAGE INCREASE AT THE END OF THE FIRST MONTH OF STORAGE, BUT IT LATER SLOWED DOWN. THE RANCIDITY INDEX SHOWED INCREASING VALUES WITHIN THE NORMAL LIMITS, THOUGH THEIR EVOLUTION WAS VERY IRREGULAR. BOTH THE INITIAL AND FINAL COUNTS OF VIABLE MICRO-ORGANISMS SHOWED NORMAL INFECTION FIGURES WHICH DECREASED DURING COLD STORAGE.
