Abstract

L'invention concerne un procédé et un emballage pour prolonger la durée de conservation des légumes. Pour prolonger leur durée de conservation, certains légumes sont placés dans des emballages qui sont au moins aussi perméables à l'anhydride carbonique, à l'oxyde de carbone et à l'oxygène qu'un polyéthylène basse densité qui n'a pas plus de 0,05 mm d'épaisseur, l'atmosphère à l'intérieur de l'emballage étant modifiée de manière qu'elle comprenne au moins environ 25 % en volume d'oxygène, au moins environ 3 % en volume d'oxyde de carbone, le complément étant en quasi-totalité de l'azote moléculaire, et on ferme ensuite les emballages. La perméabilité doit être suffisante pour empêcher que la concentration de l'anhydride carbonique ne monte beaucoup au-dessus de 20 % en volume et pour empêcher que la concentration de l'oxygène ne tombe beaucoup au-dessous de 2 % environ de volume. Application notamment au chou et à la laitue.
