Application of the Respiration Model for Young Soybean to Modified Atmosphere Packaging Systems

Abstract

Our previous model to predict the respiration rate of young soybean was introduced to the mathematical model for atmospheric change in modified atmosphere packaging (MAP) and its feasibility for design of MAP systems was discussed. Simulated O₂ concentrations were closely approximated to experimental data. On the other hand, CO₂ concentrations were estimated lower at the higher temperature conditions. It was resulted in the difference of the response of O₂ consumption and CO₂ production to the gas composition change. But the differences between estimated and measured values at the steady state of the gas composition in MAP were less than 1% at a temperature below 20°C. The model presented in this study is valid for the design of MAP systems for young soybean.
