Résumé : The optimisation of the packing of fresh fruits and vegetables under modified atmosphere requires a rigorous approach. It is first necessary to measure the respiratory parameters of the produce (O2 and CO2 respiratory intensities, the respiratory quotient, the apparent Michaelis constant for oxygen, the carbon dioxide inhibition constant and the influence of storage temperature on all these parameters). These measurements make it possible to calculate the respiratory intensity of the produce under all conditions of temperature and atmosphere. The second stage is the determination of the most favourable gas composition for maintaining the commercial and sanitary qualities of the fruits and vegetables concerned. This determination requires storage under controlled atmosphere and the results depend on the weighting of the different deterioration processes. Finally, a mathematical model is used to calculate the optimum permeabilities of the film to be used under the storage conditions entered in the model. Various software is used to simulate storage (the evolution of atmospheres) using the films available on the market and that display permeabilities similar to those previously calculated. At this stage, the functioning of the system can be verified by simulating the thermal profile of a realistic commercial channel. Finally, it is essential to verify these theoretical results by experimental work as no model is yet capable of forecasting all the types of deterioration possible. (texte intégral)
