Press, dry foods, such as tea, coffee, biscuits or snacks, are packaged in packaging bags. It is common to put preservatives in the packaging bags to extend the shelf life of the food; conventional preservatives generally choose desiccants or deoxidizers to dry Desiccant is a kind of hygroscopic substance, which can remove part of the moisture in the moist substance and dry by combining with water to form hydrate; desiccant has two kinds of calcium oxide and silicon dioxide: calcium oxide is commonly known as quicklime, and its moisture absorption effect is stronger than silica gel; Silicon dioxide is commonly known as silica gel. Its appearance is translucent and granular. After absorbing water, it will gradually change to blue-purple and purple, until pink means it is saturated; deoxidizer: It is based on iron powder oxidation reaction, because oxygen is consumed, making the container appear The "anaerobic" state can prevent the growth of microorganisms. According to common sense, if there are both deoxidizer and desiccant in the container of dry food, the dry food will have better preservation effect or prolong the shelf life.

However, when both desiccant and deoxidizer are used in the packaging bag, due to the physical difference between the two, the effectiveness of each other will be resisted.
