Summary

SEAL PACKAGING OF ORANGE [CITRUS SINENSIS (L.) OSBECK CVS. VALENCIA AND SHAMOUTI], GRAPEFRUIT (CITRUS PARADISI MACF., CV. MARSH) AND LEMONS (CITRUS LIMON BURM. F. CV. EUREKA) WITH HIGH-DENSITY POLYETHYLENE (HDPE) FILM (0.01 MM IN THICKNESS) DELAYED SOFTENING AND INHIBITED WEIGHT LOSS AND DEFORMATION OF THE FRUIT MORE THAN COOLING. SEALED FRUIT AT 293K (20 DEGC) AND 85% RELATIVE HUMIDITY (RH) HAD BETTER APPEARANCE AND WERE FIRMER THAN NON-SEALED FRUIT AT THEIR LOWEST TEMPERATURE POSSIBLE WITHOUT CHILLING INJURY AND 85-90% RH. HDPE SEAL-PACKAGING ALSO INHIBITED CHILLING INJURY OF GRAPEFRUIT AND LEMONS STORED AT 278 AND 275K (5 AND 2 DEGC), RESPECTIVELY. THE CO2 CONTENT OF GRAPEFRUIT WAS UNAFFECTED BY SEAL-PACKAGING, BUT IT WAS LOWER AT COOLER TEMPERATURES. DECAY OF CITRUS FRUIT DEPENDED MORE ON THE STORAGE TEMPERATURE THAN ON THE TYPE OF PACKAGING.
