APPLICATION OF COMBINED METHODS TECHNOLOGY IN MINIMALLY PROCESSED FRUITS

This paper presents the processes developed for preserving 'high moisture fruit products' (peach, pineapple, mango, papaya, chicozapote, banana) in seven countries in the frame of CYTED-D Program. The new technologies were based on the combination of a mild heat treatment, a slight water activity (a(w)) reduction, and addition of antimicrobials ('hurdle effect'). These minimal processes are energy efficient, satisfactory to preserve fruits in situ and open new possibilities for export markets. High moisture fruit products are shelf-stable during at least 4-8 months of storage.
