Summary

The model included equations describing fruit respiration and transpiration as well as permeation of oxygen and water vapour through the perforated film. Closed-system experiments with mango fruit revealed a linear dependence of respiration rate on O2 concentration. The model allowed analytical computation of the time course of in-package O2 concentration and relative humidity, and the results were in good agreement with experimentally measured values. Perforations had a much more pronounced effect on O2 concentration than on relative humidity. The model enabled practical predictions for designing modified-atmosphere packaging.
