Vacuum-packed zongzi can be refrigerated in the refrigerator. If it is placed on the freezing layer, it will not affect the eating. If you want to eat it in the near future, you can also refrigerate it.

Vacuum packaging, also known as decompression packaging, is to pump out all the air in the packaging container and seal it to keep the bag in a highly decompressed state. Lack of air is equivalent to hypoxia effect, which makes microorganisms have no living conditions, so as to achieve the purpose of fresh fruit, disease-free and rot-free. At present, there are vacuum packaging of plastic bags, aluminum foil packaging, glassware, plastics and their composite packaging. Packaging materials can be selected according to the types of articles. Because fruit is fresh food and still breathing, high hypoxia can cause physiological diseases. Therefore, less fruits are packed in vacuum.

How to eat vacuum-packed zongzi?

Method 1: It takes 15-20 minutes to boil with boiling water. It's recommended to plate and steam in a cage 15 minutes before serving. If it is not too big, the time can be shortened. If it is cooked, put the water into it after boiling, and cook for about 15 minutes. Just use an ordinary pot.

Method 2: Take it out, thaw it first, and then boil the water. Put the water directly into the pot after boiling. Don't put too much water. Just eat the zongzi halfway. Don't take the leaves apart, so that they won't rot. Cook on high fire for about/kloc-0.5 to 20 minutes. If you want a microwave oven, 10 minutes will do.
