1. Low temperature preservation.

2. Overnight shrimps should not be stored at room temperature. Because shrimps are rich in protein, bacteria can easily breed at room temperature and cause deterioration. Therefore, it is generally recommended to store shrimps in the refrigerator overnight. After the prawns are cooled, put them into a crisper, close the lid tightly to prevent odor transfer, and then place the crisper in the refrigerator. If the room temperature is lower than 10 degrees Celsius in winter, it can also be stored directly indoors.
