1, cold water thawing. Frozen crabs are thawed by cold water, and the thawed basin of frozen crabs is brought to a place with temperature, so that the thawed is faster. For quick-frozen foods such as aquatic products and fresh meat, they should be moved from the freezer to the freezer (1℃-10℃). The food should be moved several hours to one day in advance (depending on the size of the food).

2. Thaw with salt water. If it is too late to put it in the refrigerator, the crab can be completely thawed in salt water. This is because salt water can accelerate the melting of ice without breeding bacteria. Tap water is not suitable for thawing frozen meat.

3. Add vinegar to thaw. Vinegar can also accelerate the melting of ice. You can pick up crabs with chopsticks and soak them in vinegar mixed with water, which can also speed up the thawing of crabs.

4. Thaw in the microwave oven. When thawing in the microwave oven, you must use the lowest grade and gradually heat it. At first, heat it for about two minutes, and then determine the heating time according to the degree of thawing of crabs until it is completely thawed.
