Effects of modified atmosphere packaging on post harvest qualities of pink tomatoes.

A range of plastic films with different permeabilities (20 (PE20) or 50 micron (PE50) polyethylene, 10 micron polyvinyl chloride (PCV) or 25 micron polypropylene (PP)) were tested to study the effects of the atmospheric conditions inside modified atmosphere packaging on the postharvest quality of tomatoes harvested at the pink stage of maturity during storage for 60 days at 13 deg C. Unwrapped fruits served as controls. Tomatoes were evaluated for changes in colour, firmness, weight, titratable acidity, total soluble solids, decay and sensory attributes. O2 concentration decreased and CO2 concentration increased during the first few days of storage in modified atmosphere packaging, after which an equilibrium was reached. All unwrapped tomatoes were overripe and soft after 30 days. Sealed packaging, especially with PE50 and PP films, delayed fruit red colour development until after 30 days of storage, and fruits were still very firm after 60 days of storage. Fruits in packaging sealed with PE50 o

r PP films also showed the lowest weight losses and the highest soluble solids contents after 60 days of storage.
