This thesis investigated the potential of using modified atmosphere packaging (MAP) to maintain the quality of whole and pre-cut lettuce for longer periods than that currently
obtained in air. Achieving this goal will enable whole lettuce to be exported to South-East Asia and Japan by ship rather than expensive air freight. Furthermore, additional shelf-life of pre-cut lettuce on domestic markets will provide greater flexibility during distribution and
marketing, since storage life of these products decreases rapidly after processing.
