World wide, the market for packed, unprocessed or lightly processed vegetables, like corn salad, increases. Modified atmosphere inside the packaging (MAP) and storage under refrigeration help to reduce respiration and decay, and to maintain quality. The atmospheric composition inside the packing depends on the type of packing material, the kind of vegetable and its processing (cutting, shredding), the relation between air volume and vegetable mass, and temperature. Additionally, it is affected by the lighting and the aerodynamic conditions in the display. Usually, the display cabinets in retail outlets are well lighted to improve the sale. In this case, photosynthetic CO2 uptake may exceed respirational CO2 losses in fresh green vegetables. Therefore, the conditions for producing or maintaining of MA conditions are reversed.
