Title (EN) IMPROVEMENTS RELATING TO PACKAGING OF POTATOES
(FR) AMELIORATIONS RELATIVES A L'EMBALLAGE DES POMMES DE TERRE
Abstract:
(EN) A potato (19) is sealed into a pack (18) formed from sheet material so as to enclose atmospheric air or a comparable oxygen-containing gas. The sheet material is impermeable to the gas or semi-permeable to oxygen. The initial oxygen volume is between 4 % and 12 % of the volume of the potato. This control of the atmosphere within the pack ensures that the rate at which greening or sprouting occurs is kept low and in addition the creation of conditions which might lead to rapid decay are avoided.
(FR) Une pomme de terre (19) est hermétiquement fermée dans un emballage (18) fabriqué à partir de matériau en feuilles de manière à renfermer de l'air atmosphérique ou un gaz comparable contenant de l'oxygène. Le matériau en feuilles est imperméable au gaz ou semi-perméable à l'oxygène. Le volume d'oxygène initial se situe entre 4 % et 12 % du volume de la pomme de terre. La régulation de l'atmosphère dans l'emballage fait en sorte que la vitesse à laquelle la pomme de terre verdit ou bourgeonne demeure réduite, et en outre on évite de créer des conditions favorables à un pourrissement accéléré.
