Abstract
In this study, retail packaging for ‘Monthong’ fresh-cut durian using micro-perforated films was developed. PET/PE laminated film was perforated using CO2 laser to obtain microholes with an average size of 113.5 μm. Ripe durian pulp was packed in a PET tray and then the two levels of micro-perorated PET/PE films, MP-1 and MP-2, and non-perforated PET/PE film (control) were heat sealed as the top lidding film. O2, CO2, and water-vapor transmission rates of MP-1 film were 285, 80, and 3.6 times higher than that of control, whereas those of MP-2 were 574, 162, and 6.4 times higher. Time and temperature simulations of export logistics of fresh-cut durian was carried out in the experiment. In MP-1 package, O2 reached a steady stage at 13 % and CO2 increased to 17 %, while in MP-2, CO2 was stable at 5 % as O2 reduced to 18 %. Most storage attributes of pulp were not different between treatments. However, in control, the pulp exhibited off-flavor after day 6. Several sulphurous and ester compounds of durian were few released from the MP-2 package. © 2019 Elsevier Ltd
