Postharvest life of fruits and vegetables: model of modified-atmosphere packages with film perforations.

A model was developed to study gas dynamics in a package containing fresh fruit. The model calculated the gas balance taking into account the processes of fruit respiration and transpiration, as well as the permeation of gases and water vapour through a perforated packaging film. Equations are suggested to describe the permeation of gases and water vapour through perforations in the film. The model enabled the time course of O2 consumption, CO2 evolution and the humidity changes in the modified atmosphere enclosed in the perforated film to be computed analytically when the respiration rate depends linearly on O2 concentration, as is the case, for instance, for mangoes. Fruit weight loss in this modified atmosphere was calculated by means of the model. The model enables investigators to evaluate the film specifications and the package parameters which will provide the best conditions for storage of a given commodity.
