Oxygen Scavenger, also known as deoxidizer or desiccant, is usually used in sealed packaging to help remove or reduce the oxygen content in the package. Using Oxygen Scavenger can help maintain product safety and extend shelf life.

Common deoxidizers are the following: iron, pure iron is silvery-white, typical for pig iron, black, solid, mostly block when desiccant for powder; calcium oxide, also known as quicklime, white, solid, mostly powder; sodium hydroxide, also known as fire soda, caustic soda, caustic soda, white, solid, mostly powder.

With the packaging of the ingredients, there are usually deaerators, if a small amount of accidentally swallowed, to immediately drink water to promote metabolism, generally not easy to cause significant impact on the human body.


What does an oxygen scavenger do?

Deaerator is a corrosion inhibiting substance, added in small amounts to the environment prone to oxygen corrosion. Its cathodic nature allows it to combine with oxygen to form a harmless compound, which ultimately reduces the corrosion rate in the protected system.

Deaerators can be used in food, pharmaceutical, or other products to prevent spoilage, deterioration, mold, and deodorization. The product can maintain its quality and avoid the loss of nutrition value by using such deaerators.

Deoxidants can effectively inhibit mold and aerobic bacteria growth, extend the shelf life of food and play a good role in preventing the rancidity of fats and oils, preventing the oxidation and browning of meats, and preventing the loss of vitamins in food.


Which molecule is known as oxygen scavenger?

There are many forms of oxygen scavengers, such as powder, granular, etc. The typical components of oxygen scavengers are (1) iron-based oxygen scavenger, iron powder as the main chemical composition, supplemented by activated carbon. (2) sulfite system deaerator, that is, even di-sulfite as the leading agent, activated carbon, sulfite, alkali as a supplement to the chemical composition. (3) organic system deoxidizer.

Deaerators commonly used reaction principles are iron powder oxidation (iron system), enzyme oxidation (enzyme system), ascorbic acid oxidation, light-sensitive dye oxidation, etc. Currently, the iron powder oxidation reaction is the basis of mainly oxygen scavengers.

How do you make an oxygen scavenger?

Most standard oxygen scavengers contain ferrous carbonate and metal halide catalysts, but several non-ferrous variants, such as ascorbic acid and sodium bicarbonate.


How do you make an oxygen scavenger?

The raw materials used in different types of oxygen scavengers vary. For example, the main types of oxygen scavengers used in steelmaking are iron silica-aluminum-barium-calcium, silica-calcium cored wire, aluminum wire, aluminum-manganese iron, steel core aluminum, calcium carbide, and silicon carbide. But the main ingredient in the food is iron.

Because there are more chemical components in the deoxidizer, when you make your deoxidizer, you must be very careful to prevent danger. The direct purchase will be the easiest way to obtain.
