Summary

GAMMA RADIATION (1 AND 2 KILOGRAY) AND DIFFERENT SOURCES OF SO2 AND MOIST AIR HEAT: 328 K (55 DEG C) FOR 15 MINUTES, WERE USED TO INCREASE SHELF-LIFE OF BLACK ALICANTE TABLE GRAPES STORED AT 283 K (10 DEG C) AND 95% RELATIVE HUMIDITY. THE GRAPE CLUSTERS WERE PLACED ON FOAM POLYSTYRENE TRAYS AND PACKED WITH POLYVINYL-CHLORIDE FILM. GAMMA RADIATION COMPLETELY PREVENTED DECAY OF GRAPES STORED FOR 40 DAYS AT 283 K WITHOUT ANY DISCERNIBLE CHANGE IN THE ORGANOLEPTIC ATTRIBUTES OF THE BERRIES. MOIST AIR HEAT, 0.25% SO2 AND 1 KILOGRAY GAMMA RADIATION USED ALONE NEITHER PREVENTED NOR DELAYED MOULDING, WHEREAS POTASSIUM METABISULFITE MIXED OR NOT MIXED WITH CITRIC ACID DELAYED MOULDING FOR 15 AND 35 DAYS, RESPECTIVELY. 1 KILOGRAY GAMMA RADIATION DOSE IN COMBINATION WITH 0.25% SO2 CONTROLLED MOULDING FOR THE ENTIRE STORAGE PERIOD OF 40 DAYS.
