Crab bought home in the water for a short time to save, many people put in the refrigerator frozen, but then the crab died. The storage of crabs should be based on different situations, frozen crabs can still eat?
If the crab freezes to death in refrigeration, don't eat it because the high temperature of refrigeration doesn't stop the crab from producing harmful substances after it dies, and it may be harmful to your health to continue eating it. However, if the frozen layer freezes to death, and the time of death is not long, generally can be eaten, because the temperature of the frozen layer is basically about ten degrees below zero, can be very good inhibition of bacteria and various enzymes, delay the production of harmful substances in the body of the crab. So whether crabs can be eaten when frozen in the refrigerator depends on the situation.
If the crab is frozen alive, it may still be alive within 2-3 days, because the crab is a kind of metamerism, when it encounters low temperature, it will let its body enter into a dormant state, and only maintains the basic life activities, so as to prolong its own survival time. However, the freezing environment temperature is too low and not within the suitable survival range of crabs. So crabs can only survive for about 2-3 days and need to be consumed as soon as possible.
The flavor of sea crabs remains unchanged after 3 months of storage in a quick-freezing environment. As long as they are not thawed, the crabs will not spoil, but the taste will deteriorate. The freshwater Schistosoma pneumophila cysts are very resistant and reproducible, and even frozen dead crabs are susceptible to food poisoning. It is best not to freeze them.
Generally speaking, frozen crabs are edible, but it is still important to carefully observe whether the meat is white and tender. If it is empty and dry, feels like the crab legs are falling off, or has a strange odor, then it is best to stop eating it. Frozen crabs taste a little different from fresh crabs, but as long as they are cooked properly, they can be tasty, and as long as there are no changes in the meat or odor after thawing the frozen crabs, they can still be eaten normally.
Whether a crab is edible or not depends on the quality of the crab, not the specific storage time. During the freezing process, crabs can deteriorate due to improper storage and other reasons. It doesn't have much to do with the specific freezing time that this crab can't be eaten. Moreover, crabs can be kept for more than 3 months if they are stored properly. Of course, the longer the crabs are frozen, the greater the loss of nutrients. It is not recommended to keep crabs for too long.
What kind of frozen crabs should not be eaten?
1. Very smelly. Frozen crab itself has the odor of aquatic products, but after spoilage, the cadaverine metabolized by bacteria is very stinky and has a strong fishy smell, so it is not recommended to eat frozen crab when there is a strong fishy smell.
2, discoloration. The insides of crabs are light yellow, white and other colors. But frozen spoiled crab viscera will become black and brown, the meat will change from white to dark brown. This frozen crab can not be eaten.
