CONSERVATION DE LEGUMES EN ATMOSPHERE CONTROLEE DANS DES SACS EN POLYETHYLENE AVEC FENETRE D’ELASTOMERE DE SILICONE

The use of polyethylene bags with silicone rubber window was studied for C.A. storage of various vegetables.
Three types of bags of different capacity are first described.
The preliminary tests in order to apply these bags to the commercial storage of artichokes and asparagus at 0°C, carrots and turnips at 1° – 2°C and green peppers at 12° – 13°C are presented.
The problem was to fix for every commodity and type of bags the surface of the window ensuring a good control of the internal rates of oxygen and carbon dioxide and also a satisfactory storage.
The best control of the atmosphere inside the bags was obtained with artichokes, asparagus and green peppers.
C.A. storage of carrots and turnips was more or less perturbed by an excess of condensed water on the inner side of the window.
The storage of all vegetables in the bags was largely extended compared to the conditions in air, but the losses by decay were particularly important for peppers which seem uneasy to store with the method.
