众所周知,世界谷物、畜产品、水产品和果蔬的保藏问题尚未能得到很好解决,每年的损失是巨大的。根据国际原子能机构估计,谷物类损失10—20%,块根块茎、干燥食品损失20—40%,水果蔬菜、鱼肉类损失更为严重。因保藏不善,每年总损失约130亿美金。我国也存在类似情况,每年粮食损失约10%,油料损失20%,肉食品损失达30%。实行经济改革后,食品霉烂损失情况有所改善。但由干我国冷藏链体系尚不发达,因此, As we all know, the preservation of the world’s cereals, livestock products, aquatic products and fruits and vegetables has not yet been well resolved. The annual losses are enormous. According to estimates by the IAEA, 10-20% of cereals are lost, and 20-40% of root tubers and dried foods are lost. The loss of fruits, vegetables and fish is even more serious. Due to poor preservation, the total annual loss is about 13 billion US dollars. A similar situation exists in China. The annual grain loss is about 10%, the oil loss is 20%, and the meat loss is 30%. After the implementation of economic reforms, the loss of mildew in food products has improved. However, due to the fact that China’s cold chain system is not yet developed, therefore,
