1, frozen storage: it can be kept fresh for about 5 days in cold storage and 3 months in freezer. Zongzi is divided into several small packets when stored, and each small packet is taken out and eaten at one time, and cannot be frozen again.
2. Soak zongzi water: soak the cooked zongzi in zongzi water. Thick oil floats on the cooked zongzi, which can prevent bacteria from entering and can be stored for 3-7 days.
Don't buy or eat zongzi stored at room temperature and sold without refrigeration facilities. If it needs to be stored for a long time, it is best to put it in the frozen layer of the refrigerator. Zongzi can only be preserved after being cooked. Don't put it in the fresh-keeping layer after cooking, it will go bad easily there, and it won't go bad after ten days and a half in the frozen layer. The temperature of the refrigerator is preferably five to three degrees Celsius.
