Effect of packing and storage temperature on postharvest life and fruit quality of yellow passion fruit (Passiflora edulis var. flavicarpa).

Passion fruits harvested on the previous day were packed into 0.025-mm-thick polyethylene bags (15 x 30 cm) with 0, 6 or 12 perforations 5 mm in diameter and were stored either in ambient conditions (22 deg C and 85% RH) or at 12 deg and 85-90% RH for 7, 14, 21 or 28 days. Cold storage for 21 days significantly reduced weight loss (1.36%) compared with ambient conditions (4.45%). The lowest weight loss over 28 days, viz. 2.21% in cold storage, was obtained with fruits packed in non-perforated bags. No differences in titratable acidity or TSS were found between different packing treatments. Both acidity and TSS were higher in cold storage; their highest values were recorded at 14 and 21 days of storage and thereafter acidity, TSS and fruit firmness decreased.
