Type of article: Article

Summary

BROILERS WERE HAND PROCESSED AND RANDOMLY PLACED INTO 4 POSTMORTEM AGING TEMPERATURE TREATMENTS: 314, 301, 287 AND 273 K (41, 28, 14 AND 0 DEG C),MORE OR LESS 1 K. SARCOMERE LENGTH (SL) MEASUREMENTS WERE MADE ON LEFT PECTORALIS (P.) MAJOR MUSCLE AT 0, 1, 2, 3 AND 4 H POSTMORTEM. AT THE END OF 4 H, ALL CARCASSES (EXCEPT 273 K TEMPERATURE GROUP) WERE CHILLED AT 273 K, MORE OR LESS 1 K, FOR 1 H. THE RIGHT P. MAJOR MUSCLES WERE REMOVED, WEIGHED, AND FROZEN FOR COOKING LOSS (CL) AND TENDERNESS (KRAMER SHEAR) MEASUREMENTS. THERE WAS A SIGNIFICANT POSTMORTEM TEMPERATURE AND AGING TIME EFFECT FOR SL. OVERALL, SARCOMERE SHORTENING WAS GREAT-EST AT 273 K. OVERALL, 273 AND 287 K TREATMENTS RESULTED IN SHORTER SL, LESS CL, AND LOWER SHEAR VALUES OF P. MAJOR MUSCLE THAN 301 AND 314 K TREATMENTS.
