What is the reason for the flatulence of the vacuum packaging machine?

The reasons for flatulence after vacuum packaging can be attributed to two: 1. Improper operation during the packaging process and poor packaging. 2. Without thorough sterilization before packaging, the bacteria still survive in the food (some bacteria are anaerobic and can survive in the absence of air), and the bacteria produce gas during the reproduction process, resulting in flatulence. Compared with the first solution, it is easy to solve the problem. When packaging, observe the packaging process and operation. If there is any inappropriateness, you can consult professionals or manufacturers. For the second question, life outside the circle can't answer it for you. If the food is not completely sterilized, you need to ask the biological personnel to answer it for you.
