1, keep fresh zongzi in a cool, ventilated and dry place, and put it in the refrigerator within 12 hours, which can be kept fresh for 3 days, but not more than 7 days.

2, fresh cooked dumplings exposed to high temperature, easy to mildew, so be sure to heat and eat as soon as possible. Fresh zongzi should not be transported in the sealed and stuffy trunk of a car, otherwise it will easily deteriorate. If it is peeled off and found that there are many sticky wires, it may have been put away for a long time and it is not fresh.

3. For vacuum-packed and quick-frozen zongzi, after purchase, they should be preserved as shown in the label, and processed and eaten according to the marked eating method. Pay attention to buying zongzi in bulk, and it is best to eat and buy it now to avoid the deterioration of zongzi. Raw and cooked zongzi should be stored separately, and the opened zongzi should not be kept at room temperature for more than 2 hours.
