Effect of polyvinyl chloride film packaging on the storage life of mangosteen fruit (Garcinia mangostana L.)
Polyvinyl chloride (PVC) films of different thickness were tested to extend the storage life of mangosteen fruits. CO2 and O2 transmission rates were found to be 59.8, 33.3 and 25.0 ml.m-2.h-1.kpa-1 and 12.7, 11.3 and 10.8 ml.m-2.h-1.kpa-1, respectively, for 14, 28 and 42 um-thick films, respectively. Film wrapping retarded fruit weight loss, color changes measured as L*, a*, b* and chlorophyll content, respiration and ethylene production, with the 28 and 42 um-thick films as equally effective at 8°C and 42 um-thick films as the most effective at 13°C. Film-wrapped fruits all lasted for 16 days at 8°C while unwrapped ones, 12 days. At 13°C, unwrapped fruits also kept for 12 days while wrapped ones, 16-20 days, with 42 um-thick film causing the longest shelf life extension.
