Modified-atmosphere packaging of fruits and vegetables: reducing condensation of water in bell peppers and mangoes.

The effects of perforation of the packaging film on decay and water condensation

in bell peppers (Capsicum) and on ripening of mangoes in modified atmosphere packs are described. Perforating the film greatly affected O2 and CO2 concentrations and water condensation, but not the in-package relative humidity. Bell peppers packaged in perforated film lost weight and maintained higher quality during storage than fruits stored in open carton boxes, and had lower decay levels than peppers in non-perforated packages. Perforating the film negated the inhibition of ripening which occurred in mangoes in non-perforated packages. Perforated packages retained most of the advantages of modified atmosphere packaging. Non-perforated film of the polyamide type had similar effects to perforated polyolefin film. A dynamic model of gas and water vapour exchange in a package containing fresh fruits and vegetables based on the Michaelis-Menten equation combined with Fick's diffusion law is presented and a computer si

mulation evaluated package specifications which would provide the best storage conditions for a given commodity. Model predictions were confirmed by measured observations.
