Crab is a delicious seafood, which is rich in protein and various trace elements, which has a good tonic effect on our health. However, crab is also a perishable food that can cause waste and health risks if not stored properly. Among them, how to preserve steamed crabs is one of the issues that everyone is more concerned about. Below, I will introduce you to some methods and techniques for the preservation of steamed crabs.
After the crab is steamed, if it is not eaten immediately, the best way to preserve it is to refrigerate. Wrap the crab in plastic wrap or a clean towel and place it in the refrigerator with a temperature between 0 -4. At this temperature, crabs can be kept for around 2-3 days. However, it should be noted that crabs will deplete their own nutrients during the refrigeration process, and the taste will gradually deteriorate, so it is recommended to eat them as soon as possible.
2. Freezing method.
If you want to preserve the crab for a long time, you can freeze the steamed crab in the freezer compartment of the refrigerator. Before freezing, wrap the crab in plastic wrap or plastic bag to avoid flavor cross-flavouring with other foods. In the frozen state, crabs can be stored for more than 3 months. To eat, take out the crab and thaw it.
3. Salt water preservation method.
The brine preservation method is an ancient method of preserving food and can also be used to preserve steamed crabs. Soak the steamed crabs in brine, and the concentration of the brine should be controlled at about 20%. Under the action of salt water, the crab will form a protective film that prevents bacteria from entering, thus prolonging the preservation time. However, this method has a shorter shelf life, only about 1-2 days, and the taste is also affected.
When preserving steamed crabs, there are also a few things to keep in mind:
1) Crabs should be completely steamed before preservation to avoid bacterial breeding;
2) Crabs should pay attention to hygiene during storage and avoid contact with other foods;
3) The storage time of crabs should be judged according to the actual situation, and if there is a peculiar smell or deterioration, it should be discarded in time.
In short, how to preserve steamed crabs is a problem that needs attention. Through the methods and techniques introduced above, we can effectively extend the preservation time of crabs while ensuring their taste and safety and hygiene. We hope that everyone will be careful to stay healthy and safe while enjoying the food.
