ECONOMY OF COMBINED FREEZE AND AIR DRYING.

Summary

FREEZE-DRYING (FD) IS KNOWN TO BE THE MOST GENTLE DRYING METHOD FOR PRESERVING THE FLAVOUR AND STRUCTURE OF PRODUCTS. HOWEVER, THE HIGH COST OF OPERATION LIMITS ITS APPLICATION. AIR-DRYING (AD) HAS THE OPPOSITE CHARACTERISTICS. A COMBINATION OF THE TWO PROCESSES RETAINS THE ADVANTAGES OF FD (AS EVALUATED BY SENSORY ANALYSES) WHILE ALLOWING UP TO 50% OF THE WATER TO BE REMOVED BY AD.
