Types of deoxidizers mainly include the following categories:
Physical adsorption deoxidizer: This type of deoxidizer uses its special mesoporous structure and surface area to absorb moisture and oxygen, and is usually made of materials such as silica gel and activated carbon. They cannot be regenerated and reused, and the deoxidizer only needs to be placed in the items that need to be protected.
Chemical adsorption deoxidizer: This type of deoxidizer is made of metals such as iron and cobalt, which can react with oxygen and generate compounds to achieve the effect of adsorbing oxygen. They can be regenerated and reused. When using, the deoxidizer needs to be evenly sprinkled around the packaged items and ensure that it is in full contact with the items.
Iron-based deoxidizer: The main ingredients are reduced iron powder, carbon powder and sodium chloride. The reaction is stable and has no odor, and no harmful gases are produced. They can effectively absorb oxygen in the package to prevent oil rancidity, meat oxidation browning and vitamin loss.
Sulfite-based deoxidizer: This type of deoxidizer consumes oxygen through chemical reactions and is often used for food preservation.
Hydrogenation catalyst deoxidizer: Use catalyst to accelerate the generation of hydrogen, thereby consuming oxygen.
Glucose oxidase deoxidizer: Consume oxygen through the reaction of glucose oxidase with oxygen, suitable for environments where the oxygen concentration needs to be controlled.
Ascorbic acid deoxidizer: Use ascorbic acid (vitamin C) to react with oxygen to consume oxygen, commonly used for food preservation.
Sulfide deoxidizer: Consume oxygen through the reaction of sulfide with oxygen, suitable for occasions where a low oxygen environment is required.
Alkaline deoxidizer: Use alkaline substances to react with oxygen to consume oxygen, suitable for specific chemical environments.
