what you are asking is mainly deoxidizer. Deoxidizer is mainly used to deoxidize. In short, it reacts with oxygen to avoid chemical reaction between packaged food and oxygen, such as ha change, ha La taste, etc
Baidu: common reaction principles of deoxidizer include iron powder oxidation (iron series), enzyme oxidation (enzyme series), ascorbic acid oxidation, photosensitive dye oxidation, etc. Most deoxidizers currently used are based on iron powder oxidation reaction. The iron deoxidizer can be made into bags and put into the package to reduce the oxygen concentration to 0.01%. It is generally required that LG iron powder can react with 300ml of oxygen, and the appropriate amount can be selected according to the amount of oxygen remaining after packaging and the oxygen permeability of packaging film. The products used include candy, dried seafood snacks, cooked meat products, rice cakes, pasta, cheese and dried vegetables. In addition to bagged deoxidizer, plastic labels or various cards containing active iron powder are also inserted into the package.

that’s lime,
