The main raw materials are reduced iron powder, activated carbon, diatomaceous earth, vermiculite, sodium chloride and water. It absorbs the oxygen in the packaging container through the principle of iron powder oxidation, and quickly reduces the oxygen concentration in the food packaging to below 0.01% within 0.5-2 working days. So as to ensure that the food is not oxidized and deteriorated. Its reaction is stable, no harmful gas is generated, and no side effects. Before oxygen inhalation, the raw material is a mixture of black and gray particles, and after oxygen inhalation, it is brown and agglomerated, and the oxygen uptake is greater than the national standard “3 times the nominal oxygen uptake”.
The three-layer composite membrane structure packaging material is adopted, the outer coating layer is perforated with micro-holes, and the middle fiber layer is not perforated, so as to avoid the risk of powder leakage, and it can be used directly in contact with food.
Food oxygen absorbers require the participation of water in the process of absorbing oxygen, but the packaging of nut roasted seeds and seeds is relatively dry, and the deoxygenation performance of ordinary Oxygen absorber will be greatly reduced. The research and development can ensure the oxygen absorption performance of Chunwang oxygen absorber for roasted in the low moisture environment and ensure the fresh-keeping effect of the product.
The product meets the requirements of SB/T 10514-2008 standard, and has been tested by a third-party professional testing agency, and the oxygen intake is greater than 3 times the nominal oxygen intake.
