Abstract:

The shipping and storage life of lettuce is extended by enclosing a plurality of heads of lettuce in a plastic bag liner, preferably made of low density polyethylene, together with porous envelopes of hydrated lime and active carbon, and tightly closing the bag liner, preferably by heat sealing thereof. A controlled atmosphere of less than 1 percent carbon dioxide, about 1 to 6 percent oxygen, and zero or near zero percent ethylene is maintained around the lettuce while it is being refrigerated. Storage life is extended several-fold over the storage life of conventionally packed lettuce. Author
