Utilization of PVC film and edible films to extend the postharvest conservation of yellow melons

This work aimed to extend the postharvest life of yellow melons cv. AF-682 through modified atmosphere techniques obtained with PVC film and edible films such as carnauba wax (50%) and cassava starch (1, 2 and 3%). Fruits were wrapped with one layer of adherent and stretchable PVC film with 10 mm width. After covering, fruits were stored at 29± 2ºC and 64±1% UR for 20 days. At a 5-day interval, fruits were evaluated for individual weight, pulp firmness, total soluble solids content, titratable acidity and pH. The trial was carried out in a complete randomized design, with six replications in a factorial scheme 6x4, with six treatments and four storage periods. The use of PVC film and edible films are not recommended to extend postharvest conservation of yellow melon cv. AF-682. The fruits covered with 3% of cassava starch and PVC film presented initial process of fermentation and rot after 15 days of storage at 29ºC.
