Patent GB-2258993-A (GB)
Title: Preservation of fruit and vegetables
Inventor: DOWLING WILLIAM
IPC: A23B7/148
Filed: 1991-11-26
Abstract: The invention discloses a process for preservation of a vegetable by initially chilling it by immersion in water at a temperature in the range of 0 to 5 DEG C, immediately draining the water by centrifuging the vegetable, and packing the chilled vegetable in a wrapper which is permeable to gas. in particular, the wrapper is more permeable to carbon dioxide than to oxygen. While being stored, carbon dioxide is released by the vegetable and a substantial portion of this is stored in the wrapper, while at the same time there is a limited access of oxygen to the vegetable. An environment is induced wherein there is a relatively high carbon dioxide and a low oxygen level so that multiplication of microorganisms and anaerobic degradation of the vegetable is slowed down considerably. <IMAGE>
