Summary

Mathematical models were developed to predict the steady-state O2 partial pressures for designing modified atmosphere packages for avocado (Persea americana cv. Fuerte) fruits. The rate of O2 uptake (R(02)) was determined as a function of O2 partial pressures by mathematical characterization of O2 depletion data collected for avocado fruits in a closed system with time. Prediction curves showing steady-state O2 partial pressures for packaging ratios in the range of 1.5 to 8.6 closely resembled the curves of experimental data. Maximum benefits were obtained when the O2 partial pressures inside the package was maintained in the range of 1.5 kPa at 20 °C. As a result, film specifications and optimization of packaging ratios for avocado fruits in MA packages were calculated based on desired steady-state O2 partial pressures.
