1. Cooked crabs can be placed in the freezing layer, but the freezing time should not exceed three days. If this time is exceeded, not only the nutritional value of crabs will be lost, but also the taste after heating will be poor.

Generally speaking, it is best to put the boiled crabs in the fresh-keeping room and eat them immediately after meals, because any food can't be kept in the refrigerator for a long time. This must be noted.

If you don't finish eating crabs that night, try to steam them back to the pot before eating. If crabs come into contact with fog and dew, they will be toxic, so it is best not to store them like this.

4. If the cooked crabs are stored for a short time, you can choose to wrap them in plastic wrap and put them in a cool and ventilated place, which can generally keep them fresh for 6-8 hours, provided that the weather is cold and the temperature is low. If the weather is hot, the preservation time will be shorter.
