EFFECT OF FREEZING RATE AND TEMPERATURE ON THE MYOFIBRILLAR STRUCTURE OF BOVINE STRIATED MUSCLE.

INFLUENCE DE LA VITESSE ET DE LA TEMPERATURE FINALE DE CONGELATION SUR LA STRUCTURE CONTRACTILE DU MUSCLE STRIE DE BOVIN.

Author(s) : OUALI A.

Summary

THE EFFECT OF FREEZING ON PHYSICAL AND FUNCTIONAL INTEGRITY OF NATIVE MYOFIBRILS FROM BOVINESTERNOMANDIBULARIS MUSCLES WAS STUDIED USING 3 FINAL TEMPERATURES: 253, 223, 193 K (-20, -50, -80 DEG C) AND 2 FREEZING RATES (2 AND 10 K/MIN). THE PHYSICAL INTEGRITY WAS NOT AFFECTED FOR THE AMOUNT OF (UNFREEZABLE) WATER BUT THE THERMAL STABILITY OF MYOFIBRILS WAS SLIGHTLY DECREASED WITH THE SLOW FREEZING RATE. THE TREATMENTS AFFECTED MORE SIGNIFICANTLY THE FUNCTIONAL PROPERTIES OF THE MYOFIBRILLAR STRUCTURE. THE BENEFIT OF A RAPID FREEZING PROCESS CAN BE CANCELLED BY THE NEGATIVE EFFECT OF THE OFTEN ASSOCIATED LOW FREEZING TEMPERATURE.
