美国科学家已经找到不用化学药剂就能防止变质和腐烂的新方法。新鲜水果和蔬菜不论是完整的还是切开的，必须置于０～１８℃条件下进行贮藏，以减少细菌和真菌的危害。但在冷凉的温度下，果、菜凹陷处的有害微生物还能引起伤害。虽然切开的组织是活体，因不能进行正常的代谢过 American scientists have found new ways to prevent spoilage and decay without chemicals. Fresh fruits and vegetables, whether intact or cut, must be stored at 0 to 18 ° C to reduce the risk of bacteria and fungi. However, at colder temperatures, harmful microorganisms in the fruit and vegetable depressions can cause injury. Although the incised tissue is living, it can not be metabolized normally
