水果、蔬菜为人们提供日常生活中不可缺少的维生素、矿物质和有机酸。果蔬是生物体,含有80％以上的水分,采收后,它体内的酶不断进行代谢活动,要保持良好的鲜度和品质很困难。目前,先进国家生产的水果蔬菜,每年都有四分之一左右的腐烂损耗。因此,贮藏保鲜已成为日益重要的课题。 Fruits and vegetables provide essential vitamins, minerals and organic acids for people in their daily lives. Fruits and vegetables are organisms that contain more than 80% moisture. After harvesting, the enzymes in the body constantly metabolize. It is difficult to maintain good freshness and quality. At present, fruits and vegetables produced in advanced countries account for about one quarter of decay losses each year. Therefore, storage preservation has become an increasingly important issue.
