Pós-colheita de Annona squamosa L. recobertas com filme PVC

The objective of this work was to evaluate the postharvest quality of sugar aplle submitted to the delay in the withdrawal of the PVC film. The fruits were harvested at the stage of physiological maturity, then selected and sanitized. Some of them were individually wrapped with PVC film trademark and accommodated in styrofoam tray and the other fruits were kept without film, representing the control. The treatments applied in the fruits were: (Control) without PVC film (T1) individually wrapped with PVC film being removed with 2 days of storage (T2) of PVC film being removed with 4 days of storage and (T3) of PVC film being removed with 6 days of storage. The analyzes physical and physico-chemical properties were performed every 2 days of storage. The characteristics analyzed were: fresh weight loss (%), of pulp firmness (N), external appearance, index of cracking, acidity (mg.100L-1), pH, soluble solids (Brix) and ratios (SS/TA). The use of PVC films delayed the loss of mass in the sugar aplle and decreased the titratable acidity contents, besides having seams for better external appearance. The treatments T2 and T3 maintained a higher firmness up to the 6th day, when compared to the other treatments. The appearance of cracks was lower in the control. The PVC film is delaying the ripening of the sugar aplle, but has not diminished the quality of the sugar aplle proceedings at the end of the storage. The 6 day PVC film yielded a post-harvest life of 6 days, because despite all the cracks, it was fit for consumption.
