一、预冷的作用预冷是将采收的新鲜水果和蔬菜在运输、贮藏或加工以前迅速除去田间热和呼吸热的过程。预冷对于大多数果蔬来说是必不可少的,因为果蔬采收后携带大量的田间热,尤其是在高温季节。此外,果蔬的呼吸作用也会释放许多呼吸热,使环境温度升高,而且温度越高呼吸作用越旺盛,释放的热量也越多。加上采收过程中的机械损伤和病虫害感染 First, the role of precooling Precooling is the harvest of fresh fruits and vegetables in the transport, storage or processing before the rapid removal of field heat and heat of the process. Precooling is essential for most fruits and vegetables because fruits and vegetables carry large quantities of field heat after harvesting, especially during hot weather. In addition, the respiration of fruits and vegetables will also release a lot of heat of breathing, so that the ambient temperature, and the higher the temperature the more vigorous breathing, the release of calories. Coupled with mechanical damage and pest infestation during harvesting
