Summary

COOKED, DICED CHICKEN MEAT WAS DEHYDRATED BY VARIOUS AIR-AND FREEZE-DRYING TECHNIQUES. THE DRIED MATERIAL WAS EVALUATED TO DETERMINE SHEAR STRENGTH, FRIABILITY, COLOUR, REHYDRATION, SURFACE AREA, POROSITY, DENSITY AND PORE SIZE DISTRIBUTION. A SCANNING ELECTRON MICROSCOPE WAS EMPLOYED TO STUDY EFFECTS OF THE DRYING PROCESS ON MEAT FIBER STRUCTURE. THE AUTHORS FOUND THAT FREEZE-DRYING PRODUCED A POROUS MATERIAL WITH EXCELLENT REHYDRATION PROPERTIES. AIR-DRYING PRODUCED SAMPLES WITH LESS POROSITY AND POORER REHYDRATION. THEY CONCLUDED THAT POROSITY WAS THE PRIMARY FACTOR IN REHYDRATION POTENTIAL AND SURFACE AREA AND PORE SIZE DISTRIBUTION WAS LESS IMPORTANT.
