Summary

THE FIRST EXPERIMENT INVOLVED 30 CALVES, 15 OF WHICH WERE SUBJECTED TO THREE CONSECUTIVE 30 MINUTE PERIODS OF BLAST CHILLING AT 264, 266 AND 271 K (-9, -7 AND -2 DEG C) AT 50 MIN POSTMORTEM BEFORE BEING STORED AT 276 K (3 DEG C) + OR -1 K WITH THE OTHER 15 CARCASSES. YET SARCOMERE LENGTHS OF BOTH SUPERFICIAL AND DEEP TISSUE WERE NOT SIGNIFICANTLY DIFFERENT. THE SECOND EXPERIMENT INVOLVED 16 CARCASSES STIMULATED ELECTRICALLY WITHIN 5 MIN POSTMORTEM AND 16 CARCASSES SERVED AS CONTROLS. 8 CARCASSES OF BOTH GROUPS WERE SUBJECTED TO THREE CONSECUTIVE 30 MINUTE PERIODS OF BLAST CHILLING AT 261, 265 AND 269 K (-12, -8 AND -4 DEG C) BEFORE BEING STORED AT 276 K + OR -1 K WITH THE OTHER CARCASSES. AFTER 6 DAYS AT 276 K + OR -1 K THE ELECTRICALLY STIMULATED SAMPLES SHOWED SIGNIFICANTLY LOWER SHEAR FORCE VALUES AND A HIGHER PERCENTAGE OF DRIP LOSS. IN AN ADDITIONAL MODEL-EXPERIMENT WITH THREE CALVES THE EFFECTS OF RAPID CHILLING OF ENTIRE TEM WERE ILLUSTRATED. AS A RESULT OF CHILLING IN ICE FLAKES THE LENGTH OF THESE MUSCLES WAS REDUCED BY APPROXIMATELY 13%.
