Effect of packaging treatments and SO2 generator on the post-harvest losses of Perlette grapes.

Perlette is the commercial table grape cultivar of North India but due to high temperature and low humidity at the time of harvest postharvest losses of 25-30% occur. Firm ripe berries, harvested on 18 June, were enclosed in polyethylene liners with 0.56-1.68% perforations at 35 deg C (field temperature). Some of the packs were placed in 2 kg vented corrugated fibreboard (CFB) cartons in cold storage for 1, 2.5, 6 or 10.5 h to lower the temperature of the berries to 30, 25, 15 and 5 deg , respectively. A Dual Release SO2 generator was placed in each polyethylene liner. The sealed polyethylene liners and CFB cartons were stored at 0-3 deg and 85-90% RH for up to 60 days. After 20, 40 and 60 days the berries were assessed for flavour, storage losses and quality. Packing at field temperature (35 deg ) and storing in polyethylene liners with 1.12% perforations with Dual Release for up to 40 days resulted in the highest organoleptic score and was the most economical treatment.
