METHOD FOR KEEPING FRESHNESS OF VEGETABLE STORED IN REFRIGERATOR

摘要

PURPOSE:To bring back the temperature of vegetables stored in a refrigerator to normal temperature without lowering the freshness of the vegetables, by covering the vegetable with a polymer film in advance and slowly raising the temperature to normal temperature. CONSTITUTION:Vegetables stores in cooled state in a refrigerator is taken out of the refrigerator by covering the surface of the vegetable with a polymer film in advance and slowly raising the temperature to normal temperature under controlled condition. The polymer film used in the above process may be the one having low gas permeability such as polyvinyl alcohol or the one having selective gas-permeability such as polyvinylidene chloride, etc. The vegetable may be covered with the polymer film together with a gas inert to the vegetable.
