How long can vacuum-packed steamed bowls keep fresh?

The vacuum packaging of the steaming bowl can last about 15 days. Vacuum-packed food can still be preserved for a long time, which is generally better than putting it in ordinary bags. It can be kept for three or four months or five or six months. Do not damage the bag. If the bag is damaged, vacuum packaging is particularly effective. Even the vacuum-packed steaming bowl must be put in the freezer, because it is easy to get moldy.

If it is unopened, it can be kept for one or two months or even longer, for example, for three or four months or even one or two years. It is best to put food in the refrigerator in summer. If it is hot in summer, you can put an ice pack, which is generally in good sealing condition and will not completely melt in 2 to 3 days.

Preservation method

Cooked food cooked with packaging bags and vacuum packed can inhibit the growth and reproduction of some bacteria and the oxidation of food ingredients to some extent because it is isolated from the air. But for anaerobic bacteria, such an environment is just conducive to their growth. Therefore, if the packaging bag is strong, it is best to cook it again with the packaging bag to eliminate anaerobic bacteria and achieve the purpose of long-term preservation.

Stored in a refrigerated environment, the refrigerated environment is generally around-18℃, at which most bacteria stop growing, so even cooked food without vacuum packaging can be preserved for half a year. For food packaged in vacuum, it can be preserved for a longer time.
