冷藏保鮮庫(kù)和冷凍保鮮庫(kù)都是利用低溫來(lái)保鮮食品的冷庫(kù)，但兩者有著明顯的差別。
Cold storage and freezing storage are the cold storage, but there are obvious differences between them.
冷藏保鮮只是通過(guò)低溫降低生鮮食品、農(nóng)作物、種子果實(shí)等的生命活動(dòng)，延長(zhǎng)其鮮度保質(zhì)期，這時(shí)候食品的生命活動(dòng)還是有的，只是很微弱了。
Cold storage is only through the low temperature to reduce fresh food, crops, seed and other life activities, to extend the freshness of the shelf life, and this time the life of food is still there, but very weak.
冷凍保鮮是先使食品凍結(jié)后再存儲(chǔ)的，食品一旦被凍結(jié)，其生命活動(dòng)就完全停止，可以長(zhǎng)期保存。冷凍保鮮的優(yōu)點(diǎn)在于保鮮期比冷藏保鮮長(zhǎng)得多，而且食品完全停止生命活動(dòng)，可以省下很多管理工序。不過(guò)缺點(diǎn)在于冷凍保鮮會(huì)對(duì)食品的組織結(jié)構(gòu)造成一定程度的破壞。
Frozen fresh is the first to freeze the food and then store the food once frozen, the life of the activity can be completely stopped, can be long-term preservation. The advantage of frozen storage is that the preservation period is much longer than that of the cold storage, and the food is completely stopped. But the disadvantage is that the frozen fresh food will cause a certain degree of damage to the organization structure of food.
保鮮食品要用哪種冷庫(kù)，就要看食品的特性了。例如：水果、蔬菜等更適宜選用冷藏保鮮庫(kù)，肉類、海鮮可選用冷凍保鮮庫(kù)。

Fresh food to use which kind of cold storage, we must look at the characteristics of food. For example: fruits, vegetables, and more suitable for the use of frozen storage, meat, seafood can choose frozen storage.
