what is in oxygen absorbers
Their primary function is to enhance the shelf life of products and prevent the negative effects of oxidation, all while the ingredients are hermetically sealed inside food friendly packaging. âI opened an oxygen absorber once and thereâs black powder inside.â The black powder inside is iron. When the iron powder comes into contact with oxygen, it begins to absorb it and the iron becomes oxidized instead of the product. That is how an oxygen-less state is achieved inside a package.
