摘要
预冷可降低果蔬采后呼吸强度,抑制酶和乙烯的释放,降低果蔬生理代谢率,阻止果蔬品质变化,减少果蔬采后损失,是冷链物流的首要环节,对果蔬贮藏、加工、流通等过程中的品质、价值都有重要意义。本文分析并介绍了预冷的定义及种类,不同预冷方式的优缺点、适用范围等;对比了我国与国外在预冷装备与技术上的差距,指出了我国果蔬预冷现状的不足,并展望了我国预冷产业未来的发展方向。
Precooling can reduce postharvest respiration,inhibit the release of enzymes and ethylene,decrease the physiological metabolism rate of fruits and vegetables,prevent the change of fruit and vegetable quality,reduce the loss of postharvest fruits and vegetables.Precooling is the first link in the cold chain logistics,and it is of great significance to the quality and value of fruits and vegetables in the process of storage,processing and circulation.This paper analyzed and introduced the definition and types of precooling,the advantages and disadvantages of different precooling methods,the scope of application and so on.The difference between precooling equipment and technology in China and abroad was compared.The deficiency of the precooling of fruits and vegetables in China was pointed out,and the future development trend of China's precooling industry was forecasted.
