Modélisation mathématique des systèmes d'emballage sous atmosphère modifiée conçus pour les pommes.

Development of a mathematical model of modified atmosphere packaging (MAP) systems for apples.

Auteurs : MERTS I., CLELAND D. J., BANKS N. H., et al.

Résumé

An unsteady-state mathematical model was developed for MAP of apples in cartons. Key processes included in the model were: fruit respiration as a function of temperature and fruit O2 and CO2 concentrations; heat, O2, CO2, N2 and H2O exchange between the fruit, package and external atmospheres; changes in MAP film permeability with temperature; condensation of moisture within the package; and moisture sorption by paper-based packaging materials. Gas concentrations and temperature were assumed to be uniform throughout the package. Use of the model as a package design and optimization tool would substantially reduce the time, cost and risk of developing and testing new MA packaging systems.
