CALCULATION OF WATER ACTIVITY ON THE SURFACE OF HOT BONED MUSCLES DURING CHILLING.

Author(s) : DAUDIN J. D.

Summary

THE WATER ACTIVITY OF MEAT DURING CHILLING DETERMINES THE ROF WEIGHT LOSS AND THE GROWTH OF MICROORGANISMS. THE AUTHOR DESCRIBES A METHOD FOR MEASURING THIS PARAMETER, BASED ON THE EQUATION OF MASSTRANSFER THROUGH A BOUNDARY LAYER. IN ADDITION TO AIR PROPERTIES, IT IS NECESSARY TO MEASURE WEIGHT LOSS AND SURFACE TEMPERATURE CONTINUOUSLY. THE METHOD CAN BE APPLIED TO PRODUCTS WITH A COMPLEX SHAPE SUCH AS MUSCLES. THE CALCULATION INCLUDES 2 STEPS: 1. CALCULATION OF A TERM DEPENDING ON THE SHAPE AND SIZE OF THE PRODUCT AND AIR FLOW ; 2. CALCULATION OF WATER ACTIVITY AS A FUNCTION OF TIME BY USING THE PRECEDING TERM. THE METHOD WAS APPLIED TO HOT-BONED BOVINE MUSCLES. THE CALCULATED DATA FOR WATER ACTIVITY SHOW THAT BACTERIAL GROWTH IS PROBABLY INHIBITED DURING COOLING.
