Portunus crab is a common food in life. It has many ways to eat and high nutritional value, and is deeply loved by people. Portunus usually eat fresh, and dead Portunus can be refrigerated or frozen in the refrigerator for a short time, but it will easily breed bacteria and microorganisms for a long time and is not suitable for eating.

How to preserve dead Portunus?

1. Cold storage

Portunus crab contains more protein. For swimming crabs that have just died, it is easy to get worse if they are not treated in time. Therefore, it is recommended to wash and cook first, and then store in the refrigerator. This can prevent the growth of bacteria and keep it for 1-2 days.

2. Frozen storage

If the swimming crab can't be eaten in a short time and wants to be preserved for a long time, it is necessary to clean the dead swimming crab first, then cook it, and finally store it in the refrigerator. This can not only preserve Portunus trituberculatus for a long time, but also prevent Portunus trituberculatus from losing more crab roe and crab paste during storage and thawing.

Can dead swimming crabs still be eaten?

It depends on the situation.

Swimming crabs belong to sea crabs. After crabs are caught and put into the sea, their survival time is not long. Generally speaking, all the swimming crabs sold in the market are dead swimming crabs. Portunus with short death time can be eaten. Because the sea area where Portunus trituberculatus lives is cleaner than that of Eriocheir sinensis, there are not many bacteria and microorganisms in the body, and the time of invasion and deterioration by bacteria is relatively slow, so as long as it is scientifically and reasonably refrigerated, dead Portunus trituberculatus can still be eaten. However, if the relatively lifeless swimming crab has obvious deterioration, such as stale taste and soft shell, there will be more bacteria inside, and this swimming crab is inedible.

How long can Portunus trituberculatus be kept at room temperature?

Portunus crab is a kind of seafood. It is usually difficult to survive for a long time away from the living environment. If it is stored at room temperature, it may be easy to die and deteriorate. Can be stored for 3-5 days. However, for better meat quality, it is recommended to eat it within 2 hours. At the same time, don't buy too much at once. It is best to buy a quantity that can be eaten at one time.
