1. Common methods of preserving live crabs
The following are the most discussed methods of preserving live crabs on the Internet for your reference:
| Save method | Applicable scenarios | save time | Things to note |
|---|---|---|---|
| Refrigeration method | Short-term storage (1-3 days) | 1-3 days | Need to be covered with a wet towel to prevent crabs from dehydrating |
| Aquaculture | Short-term storage (1-2 days) | 1-2 days | Use shallow water to avoid suffocation of crabs |
| freezing method | Long-term storage (more than 1 month) | More than 1 month | Need to be steamed first and then frozen to maintain the taste |
2. Detailed saving steps
1. Refrigeration method
Place live crabs in the refrigerator compartment (temperature controlled at 5-10°C), and cover the surface of the crab with a wet towel or wet gauze to prevent it from dehydrating and dying. Check the towel moisture every day to ensure the crabs are alive. This method is suitable for short-term storage, up to 3 days.
2. Aquaculture
Put live crabs into a larger container and add a small amount of water (the water level should not exceed half of the crab's body) to prevent the crab from dying due to lack of oxygen. The container should be placed in a cool and ventilated place, and the water should be replaced regularly. This method is suitable for storage for 1-2 days.
3. Freezing method
If long-term storage is required, it is recommended to steam the crabs first, then place them in a plastic bag and seal them before storing them in the freezer of the refrigerator. Frozen crabs can be stored for more than 1 month, but the taste will be slightly reduced.
3. Precautions for preservation
Here are some special considerations when preserving live crabs:
| Things to note | Specific instructions |
|---|---|
| avoid bundling | When saving, try to untie the rope to prevent the crab from consuming energy due to struggle. |
| keep moist | When refrigerated or raised in water, the environment must be moist to prevent crabs from dehydrating. |
