Raw zongzi can't be frozen in the refrigerator. Because the taste of frozen glutinous rice will become worse and it is not easy to cook. If there are other fillings in it, it will taste bad after freezing. Jiaozi sold in the supermarket is also cooked, so it is recommended to cook it before freezing it. Raw zongzi must be cooked before freezing. Zongzi is mainly glutinous rice, and its taste is soft and glutinous. Cooked zongzi can not be eaten, but can be frozen in the refrigerator, which can prolong the shelf life of zongzi at low temperature.
However, due to the low temperature in the freezer, it is not particularly convenient to put zongzi into the freezer, which will lead to the hardening of zongzi, and it needs to be thawed in advance when it is taken out for eating. Secondly, the taste of frozen zongzi will be worse, and it will not have the soft taste as before, and it will also have a little sandy taste. Therefore, it is generally recommended not to freeze zongzi.
Storage method of zongzi:
1, raw zongzi
Due to the hot weather, high temperature and high humidity in summer, it is suitable for the growth and reproduction of various microorganisms, pathogenic bacteria and molds. Zongzi contains water and consists of glutinous rice, meat (or red bean paste) and other raw materials. It is easy to deteriorate when stored at room temperature for more than 2 hours.
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 degrees Celsius to three degrees Celsius.
2. Fresh zongzi
Fresh zongzi is most afraid of sultry weather. If exposed to high temperature, it is easy to mildew and deteriorate. So be sure to heat it as soon as possible after you buy it. If you don't eat it for a while, you should open the bag in a cool, ventilated and dry place in time and put it in the refrigerator within 12 hours. It can be kept fresh for about 3 days at the low temperature of 0℃~4℃, and it can be kept in the freezing room of-18℃ for a longer time. Never transport fresh zongzi home in a sealed and stuffy car trunk, otherwise it is very easy to get moldy.
Step 3 Quick-freeze jiaozi
Quick-frozen zongzi requires high storage and distribution. When shopping, citizens must pay attention to buying quick-frozen zongzi in the freezer of the supermarket, and put it in the freezer of the refrigerator as soon as possible after returning home to ensure that it is stored below-18℃. Quick-frozen zongzi must be fully heated before eating, preferably boiled in boiling water for 13~ 15 minutes.
4.vacuum zongzi
Vacuum zongzi is best placed in a cool and dry place, and special attention should be paid not to let the sun shine directly. Due to the long shelf life of vacuum dumplings, it is necessary to check whether they leak or swell before eating.
Never eat if there is air leakage or flatulence before eating. Zongzi is usually stored at 8 ~ 15℃, vacuum-packed Zongzi can be stored for three months, and non-vacuum-packed Zongzi can only be stored for 3~5 days. When the temperature is lower than 8℃, the structure of glutinous rice will change, the texture will become rotten and the taste will be moldy. Therefore, citizens should not blindly buy too many zongzi at a time.
