Maintaining product freshness is a constant challenge across many industries, from food manufacturing to pharmaceuticals. NINGBO INNO PHARMCHEM CO.,LTD. offers oxygen absorbers as a key solution for combating spoilage and extending the life of sensitive products. This guide provides an in-depth look at how to effectively use oxygen absorbers to maximize freshness.

Oxygen absorbers are small packets containing materials that chemically react with oxygen. The most common type utilizes iron powder, which oxidizes when exposed to oxygen, thereby removing it from the package's atmosphere. This process drastically reduces the oxygen level, preventing oxidation, the growth of aerobic microorganisms like mold and bacteria, and preserving the product's original qualities. This is the essence of food preservation technology.

Understanding how do oxygen absorbers work is the first step to using them correctly. They are typically placed inside the primary packaging of the product. Once the package is sealed, the absorber begins its work. The effectiveness depends on the absorber's capacity (measured in cc) and the volume of air within the package. It's crucial to select an absorber with sufficient capacity to absorb the total amount of oxygen present. For example, when buying oxygen absorbers for snacks, consider the volume of the snack bag and the number of absorbers needed if multiple are required.

The benefits of food grade oxygen absorbers are extensive, particularly for the food industry. They are instrumental in maintaining the color, aroma, flavor, and nutritional value of food products. For items like dried fruits, nuts, baked goods, and processed meats, this means preventing rancidity, discoloration, and staleness, thereby ensuring a longer and more enjoyable shelf life. These are fundamental shelf-life extension techniques.

When selecting oxygen absorbers, several factors should be considered:

  • Product Type: Different products have varying sensitivities to oxygen and moisture.
  • Package Volume: The amount of air inside the package dictates the required absorber capacity.
  • Desired Shelf Life: A longer shelf life may necessitate more absorbers or a higher-capacity type.
  • Storage Conditions: Extreme temperatures or humidity can affect performance.
  • Metal Detection Requirements: For products processed through metal detectors, non-iron absorbers might be necessary.

Best practices for using oxygen absorbers include ensuring they are kept in their airtight packaging until ready for use, as exposure to air will deplete their oxygen-absorbing capacity. Once a packet is opened, it should be used immediately or the unused portion resealed tightly. Proper sealing of the final product package is also critical to prevent oxygen ingress.
