Effect on shelf-life and quality of passion fruit with polyethylene packaging under specific temperature

Full ripe fruits of purple passion fruit were packed in perforated and non-perforated high density polyethylene (HDPE 0.03 mm, 0.05 mm, 0.08 mm) and low density polypropylene (LDPP 0.025 mm) and stored at ambient (265 degrees C, 65.7% RH) and 5 degrees C. Fruits packed in perforated HDPE of 0.03 mm thickness showed a shelf-life of 28 days at 5 degrees C as against 4 days for control. Quality and nutritional value of fruit were better preserved, but there was slight reduction in flavour and colour of juice. The quality parameters, total soluble solids, titratable acidity, sugars and ascorbic acid contents were at par with initial value even after 28 days of storage.
