Resumo: The preservation of horticultural products by modified atmosphere requiring the understanding of the phenomena of mass transfer, due to gas exchanges through the packaging material, and heat transfer, due to temperature changes, which occur from the moment the product is packed. The mathematical modeling of these phenomena allows to design the modified atmosphere package (MAP),which means to select the packaging material and to determine its characteristics the gas permeabilities, namely to O2 and CO2 the area and the thickness required in the way to establish the gas concentrations recommended for the extension of shelf-life, maintaining the quality of the product. Several models have been used in MAP, the polymeric film and the perforation.
