Summary

A respiration model, based on enzyme kinetics, was proposed for predicting respiration rates of fresh produce as a function of oxygen and carbon dioxide concentrations. In this model, the dependence of respiration on oxygen was assumed to follow a Michaelis-Menten type equation and the effect of carbon dioxide on respiration to follow an uncompetitive inhibition model. The model predictions agreed well with published data for a variety of commodities and with experimental data for cut broccoli. Fresh produce respiration rates at various oxygen and carbon dioxide concentrations, as well as transient and equilibrium gas concentrations within permeable packages, could be accurately predicted with the model equations.
