Why does the modified atmosphere packaging machine change the freshness of food?

The food packaging produced by the modified atmosphere packaging machine adopts vacuum means, and an anaerobic state is formed in the packaging container, so that the packaging acts as a medium to isolate the food from the outside air. This is an extremely effective way to keep many foods fresh.

Whether it is perishable fruits and vegetables, or modified atmosphere packaging for meat/seafood, packaging can act as an effective umbrella while maintaining the taste of the food.

Of course, in order to maintain a better sense of red meat products (bright red), it is also a good choice to use vacuum and then air-filled sealing (modified atmosphere MAP).
