It depends. After making the Lantern Festival, open the packaging bag as soon as possible and put it in a ventilated and low-temperature place. Storage time is recommended not to exceed 24 hours. If it is kept in the refrigerator, it should not exceed 7 days. If it is sealed in the frozen layer of the refrigerator, it should not exceed 1 month. Because Yuanxiao is stored in a low temperature environment for a long time, not only the taste will change, but also the nutritional value will gradually decrease.
