Q:Is the packet in the food package a reducing agent or an oxidizing agent?
In many food packages, the Producers place a packet of antioxidants and note the words "antioxidants, not edible". Its function is to absorb oxygen in the food bag, so that the oxygen level in the bag is controlled at a very low level, to prevent the proliferation of microorganisms in the bag. Because the growth and division of microorganisms require the participation of oxygen, the spores and hyphae of microorganisms are strongly inhibited under anoxic conditions. Thereby, the food in the bag is preserved, and the probability of microbial contamination is reduced.

Q:What's the packing of the air in the food package?
For example, our common bag of potato chips, which is mostly nitrogen N2, a gas filling packaging is fat, on the one hand is the replacement of the original air bag and prolong the shelf life; on the one hand, there is a large amount of gas support chips during transportation and storage, can also be to reduce the impact of fragmentation. You certainly don't want to buy potato chips all over it.
