Extended data:
Be sure to put it in the refrigerator. Zongzi is mainly glutinous rice with red dates, bean paste or meat, so it is easy to deteriorate in hot weather in early summer. Jujube zongzi and red bean paste zongzi can be stored in the refrigerator for 3-5 days. If it's meat stuffing, it's best to eat it within 3 days.
At present, zongzi on the market can be roughly divided into three categories according to their packaging and preservation forms: fresh packaging, quick freezing and vacuum packaging. It's best to eat fresh zongzi on the same day after buying it home, otherwise it should be stored in the refrigerator in time.
Both frozen and vacuum-packed zongzi can be preserved for a long time and can be eaten within the shelf life of its label. But pay attention to the classification, put it in bags and put it in the refrigerator. If you make zongzi at home, it is best and safest to cook it now. But pay attention to the cold storage for no more than 3 days and the freezing for no more than 7 days. Steam it again when you eat it again, but it is best not to freeze it again.
Another thing to note is that if the dumplings are sticky after peeling, it means that the dumplings may not be fresh for a long time, so it is best not to eat them.
Eating zongzi on Dragon Boat Festival is taboo.
