Keeping quality of fresh figs by postharvest film wrapping.

ABSTRACT :

 

Fresh fruits of cv. Niedda Longa were harvested when ready to eat and placed in polystyrene trays (15 to a tray). Trays were then left unwrapped (control), or wrapped in 15- micro m-thick extensible PVC film or in 15- or 19- micro m-thick polyolefinic heat-shrinkable film and stored for up to 16 days at 0 deg C and 95% RH. Trays were transferred at 4-day intervals for 3 days at 20 deg and 75% RH to simulate merchandizing conditions. Wrapping in plastic film reduced weight loss due to transpiration and delayed fruit shrivelling. There were no significant differences in weight loss and overall appearance between fruits wrapped in the 2 types of film. The external appearance of fruits slightly deteriorated by the end of the simulated merchandizing regardless of cold storage treatment, but sound fruits were not judged unacceptable. Wrapped fruits exhibited a slight off-flavour and off-odour. Cold storage was effective in reducing fruit rot. The incidence of decay increased markedly during merchandiz

ing. Wrapped fruits showed the highest incidence of rotting (due to Alternaria alternata, Aspergillus niger, Botrytis cinerea and Penicillium italicum).
