Dual-Effect Oxygen Absorber/Deoxidizer: Principle and Fresh-Keeping Effect in Dried Fish and Dried Fruits

Uncategorized

I. Definition and Working Principle of Dual-Effect Oxygen Absorber/Deoxidizer

  • Definition: A food preservative with dual functions of oxygen absorption and moisture removal. It achieves fresh-keeping effects through the synergistic effect of core components, and is widely produced and supplied by many reliable China Supplier entities that specialize in manufacturing high-quality Oxygen Absorber/Deoxidizer products.
  • Oxygen Absorption Principle: In the presence of moisture, the iron powder in the components of the Oxygen Absorber/Deoxidizer reacts with oxygen in the air to form iron oxides. This reaction effectively consumes oxygen in the packaging, achieving the purpose of deoxidation. Most China Supplier brands optimize this reaction process to enhance the oxygen absorption efficiency of their Oxygen Absorber/Deoxidizer.
  • Moisture Removal Principle: Calcium chloride, a commonly used moisture-absorbing component in the Oxygen Absorber/Deoxidizer, has strong hygroscopicity. It absorbs moisture in the air and forms calcium chloride hydrates with different crystal waters, thereby reducing the environmental humidity inside the packaging. China Supplier usually selects high-purity calcium chloride to ensure the stable moisture removal performance of the Oxygen Absorber/Deoxidizer.

II. Key Purposes of Using Dual-Effect Oxygen Absorber/Deoxidizer in Dried Fish and Dried Fruits

1. Prevent Oxidative Deterioration: The Oxygen Absorber/Deoxidizer absorbs oxygen in the packaging, which can inhibit the oxidation of fats in dried fish and dried fruits (avoiding the generation of a rancid taste) and reduce the loss of nutrients. At the same time, it blocks the growth of aerobic microorganisms such as mold and bacteria. Many China Supplier provide customized Oxygen Absorber/Deoxidizer solutions for dried aquatic products and dried fruits to better meet this anti-oxidation demand.

2. Maintain Ideal Taste: The moisture removal function of the Oxygen Absorber/Deoxidizer can keep dried fish dry and chewy, and maintain the appropriate flexibility of dried fruits. It prevents the ingredients from becoming soft, caking or moldy due to moisture, thus extending the shelf life and improving the eating experience. China Supplier often conduct strict quality tests on their Oxygen Absorber/Deoxidizer to ensure that the moisture removal effect meets the storage requirements of dried fish and dried fruits.
