What is the function of ultra-low temperature quick freezing? How long can seafood be kept in it?

Ultra-low temperature quick freezing can effectively kill bacteria without destroying the original cell structure of food. Seafood can be stored in it for up to 18 months. If you want to buy seafood, I recommend you to use the "Seafood One Yuan Pai" APP. The seafood in it is caught directly from the sea by fishing boats and frozen in the ultra-low temperature freezer. It is very fresh.
