How long crabs can be kept frozen varies depending on whether they are cooked or raw. Cooked crabs can be stored in the refrigerator for one to two days, while raw crabs can be stored in the refrigerator for up to three months. In addition, crabs are a cold food and can be kept in the freezer for a longer period of time as compared to warm meats, which is generally common around two weeks. Therefore, the longest time crabs can be kept frozen is about three months. However, it is best to consume them within this period, as the edible taste of crabs gradually decreases with the longer preservation time.

However, it is best to consume them within this period, as the preservation time becomes longer, the edible taste of crabs is also gradually declining. 1, crabs can be kept in the refrigerator for 1-3 months. 2, the advantage of the refrigerator is the low and constant temperature. The temperature of the freezing layer of the refrigerator will be relatively lower than that of the outdoor, which can effectively inhibit the reproduction process of bacteria, microorganisms and various enzymes, so you can freeze crabs. If the refrigerator refrigeration effect is good, crabs can generally be frozen for about 1-3 months. However, although the crab can be saved for a long time without deterioration, but with the extension of the freezing time, its nutrients and taste will be greatly reduced, so frozen or eat crab as soon as possible as well.
