According to the truth, if you eat crabs at home, the first day you are alive, and the second time you eat them, you die. This effect can be ignored. But if it is true, live crabs are definitely much more delicious than dead crabs. In the quick-frozen industry, there is a * * * knowledge, that is, if seafood can be frozen instantly, its freshness is the greatest. Generally, the temperature used for quick freezing is below-0/8℃. Although the temperature in the refrigerator can reach this level, the speed of quick freezing is certainly not as fast as others.
As for refrigeration or freezing, the optimum temperature for storing frozen items in general household refrigerators is-18℃, and the optimum temperature for refrigerating rooms is about 5℃. Although crabs can survive at around 0℃ in theory, personally, it is really unnecessary to put them in the refrigerator.
Since it's the next day, why not find a bucket with less water and leave them for a day? Moreover, many crabs still have dirty things in their bellies. After a day's feeding, crabs will excrete some and eat more cleanly. The most important thing is that no matter where crabs are stored, the living ones are definitely fresher than the dead ones.
If we look carefully when buying crabs, we will find that those crabs that are alive and kicking are raised in water, and then those crabs that are half dead or dead will be stored in ice tables or freezers. Mainly to extend the shelf life of dead crabs. So, you eat crabs at home. If crabs are alive and kicking, keep them in a bucket for one day and eat fresh hairy crabs the next day. This is called seafood.
In addition, expand your knowledge. When washing crabs, it is best to wash them with a brush. Many crabs are covered with dirty things, and they can't be cleaned without a brush. Like crabs, the back, abdomen and mouth are the dirtiest, so it's best to brush them several times.
