If it is fresh live crab, it can be stored in the refrigerator for about 1 week.

Sea crabs can be stored in the freezer of the refrigerator. If they can be vacuum-frozen, the effect will be better. In the past, mainlanders ate frozen dead crabs when eating sea crabs. When a crab is dying or after death, the parasitic bacteria in the body will multiply and spread rapidly.

Break down proteins and produce histamine. The longer the crab is dead, the more histamine builds up. Histamine can cause telangiectasia and bronchoconstriction in humans, causing a certain degree of damage to the kidneys.

Refrigerating time

If the crabs are refrigerated in the refrigerator, they can be kept alive for about three days. We only need to tie the crabs, control the temperature of the cold storage layer of the refrigerator between three and six degrees Celsius, and then cover their surface with a wet towel.

It should be noted that we can observe whether there are crabs in the refrigerator whose vitality has deteriorated every day. We only need to press the crab's eyes or untie the rope to see whether its movements are strong and sensitive, and eat the crabs with poor vitality in time. Just drop it.

In addition to keeping the crabs in the refrigerator, we can prepare a bucket that the crabs cannot climb out of, then spread the crabs into it, and then pour food into the bucket that will not submerge the crabs. Body water will do.
