It is a good idea to preserve seafood with dry ice pellets or dry ice blocks. In the summer, seafood is not easy to store and is prone to odor. But seafood is one of the most popular high-end foods in the summer, so in order to eat fresh seafood, people have tried all kinds of ways to preserve seafood, such as using ice cubes.
然而，夏天炎热的时候，这些保存海鲜的方法就不太管用了。最近在酒店吃干冰海鲜的时候，学到了一个用固体二氧化碳干冰保存海鲜的好方法。我自己尝试过，海鲜可以保存很长时间。值得推荐。
How to preserve live seafood with solid dry ice blocks or dry ice pellets?
Seafood should be kept in a ventilated foam incubator, and the seafood and dry ice should be stored in a stack. First, put a layer of dry ice granules or dry ice blocks in a foam box, then lay a layer of hay on the dry ice, or well-breathed cotton or sponge, then place the crab and other seafood on it. The dry ice and crabs should be in a layered manner to keep the seafood alive for a long time.
The preservation of seafood requires a suitable temperature. Preserving live seafood must give seafood products a comfortable environment. Only when the temperature is right, the seafood will not die very quickly, too cold or too hot will be not good. Usually, the temperature is determined according to the characteristics of each kind of seafood. Therefore, dry ice products and live seafood cannot be directly contacted, because the dry ice temperature is extremely low, and the seafood will be frozen to death.
Why dry ice blocks can be used to preserve seafood?
干冰之所以能保鲜海鲜，是因为它的温度很低，可以达到-78度，而且环保无污染，运输和使用方便。此外，固体干冰能挥发成二氧化碳气体，具有阻隔氧气、防止腐蚀的作用。
二氧化碳气体的比重比空气大，可以覆盖在海鲜表面，起到氧气屏障，降低海鲜的氧化速度，抑制细菌的生长繁殖，这是干冰在海产品中的独特优势。食品和海鲜的保存。
