Equilibrium Modified Atmosphere Packaging (EMAP)
Among fresh-cut produce Equilibrium Modified Atmosphere Packaging (EMAP) is the most commonly used packaging technology. When packaging vegetables and fruits the gas atmosphere of package is not air (O2 21%; CO2 0.038%; N2 78%) but consists usually of a lowered level of O2 and a heightened level of CO2. This kind of package slows down the normal respiration of the product to prolong its shelf-life. Of course there are other factors, like the size of the product, severity of preparation, maturity of the product and type of tissue that have an effect to the shelf-life of an EMA packaged produce.
