Effect of polyethylene film packaging on the storage life of mangosteen fruit (Garcinia mangostana L.)
Polyethylene (PE) films of different thickness were tested to prolong the storage life of mangosteen fruits. CO2 and O2 transmission rates were found to be 16.7, 4.5 and 2.9 ml.m-2.h-1.kpa-1and 11.1, 7.4 and 7.3 ml.m-2.h-1.kpa-1, respectively, for 10, 40 and 80 um-thick films, respectively. PE packaging regardless of film thickness and storage temperature comparably decreased weight loss and retarded peel color change. Respiration and ethylene production were also reduced, with the 40 um-thick films as more promising. Storage life consequently increased to 20 days in all film-wrapped fruits while that of unwrapped fruits, 16 days at 8°C. At 13°C, unwrapped fruits also stored for 16 days similar to that of fruits in 10 um-thick films. Fruits in 40 and 80 um-thick films had a storage life of 24 days but the 40 um-thick films maintained better fruit quality.
