Abstract
Abstract A mathematical model was developed for estimating the changes in the atmosphere and humidity within perforated packages of fresh produce. The model was based on the mass balances of O2, CO2, N2 and H2O vapours in the package, which include terms for their transfer through perforations and film, respiration and water transpiration. The model was verified by comparing predicted and measured gas compositions and relative humidities inside experimental packages of peeled garlic cloves stored at 5 and 20 °C. The model was then applied to commercial-sized packages with 0, 6 and 992 perforations at 5 °C, and the quality attributes of the cloves were monitored. Hermetic packaging, which produced a modified atmosphere of 0% O2, 5–15% CO2 and saturated humidity, was better than perforated packages, which were tested to see if they maintained the freshness of the peeled garlic cloves.
