A Kinetic Model for Predicting Temperature in Modifier Atmosphere Packaging (MAP) for Hung Yen Longan

Abstract

In a modified environment package (MAP), the fresh fruit's quality and shelf life must be preserved with
careful temperature control inside the box. In this research, a kinetic model for MAP temperature prediction
was built. The model was based on a system of differential equations that includes respiration heat (a
Michaelis-Menten type equation), energy balances, and the phenomenon of gases flowing throughout the
package. The fourth-order Runge-Kutta method was utilized to numerically solve the system equations. Using
experiment data for different types of packing film, the model's usefulness for forecasting the temperature of
MAP containing Hung Yen Longan was successfully verified
