Selecting the correct oxygen absorber is critical for achieving optimal food preservation. As a manufacturer and supplier deeply involved in food safety and quality, we understand that the effectiveness of these deoxidizers hinges on choosing the right specifications for the intended application. Whether you are a food producer, a packaging specialist, or a procurement manager looking to buy high-quality oxygen absorbers, this guide will help you navigate the essential considerations.

Decoding Oxygen Absorber Specifications: CC and Beyond

The primary specification for oxygen absorbers is their absorption capacity, measured in cubic centimeters (CC). This CC rating indicates the volume of oxygen a single sachet can absorb. For example, a 200 CC oxygen absorber can remove 200 ml (or 200 cm³) of oxygen. The amount of oxygen present in a package is influenced by the product's density and the volume of air headspace within the packaging. Therefore, calculating the appropriate CC rating is crucial.

How to Determine the Right Size: A Practical Approach

To buy the correct oxygen absorbers, consider these factors:

  • Package Volume: The total internal volume of your packaging is the starting point. A larger package will naturally contain more air and thus more oxygen to be absorbed.
  • Product Density and Headspace: Denser products, like beans or grains, leave less air volume (headspace) in the package compared to lighter, fluffier items like freeze-dried fruits or powders. You'll need to account for this difference. A general rule of thumb is to estimate the air volume within the package that needs to be cleared of oxygen.
  • Product Type: Some products are more sensitive to oxidation than others. For highly sensitive items like whole-fat foods, nuts, or seasoned products, it’s often recommended to use an absorber with a slightly higher CC rating to ensure complete oxygen removal.

As a leading manufacturer, we offer a range of sizes, typically from 30 CC to 1000 CC, to accommodate various packaging needs. For instance, smaller sachets (e.g., 30-50 CC) might be suitable for small snack packs, while larger ones (e.g., 200-500 CC) are ideal for larger bags of dried foods or bakery items. It’s always better to slightly overestimate the required CC capacity than to underestimate it, ensuring complete oxygen removal and maximum shelf-life extension. When you buy from us, our sales team can assist with precise calculations based on your specific product and packaging dimensions.

Beyond CC: Other Important Considerations

While CC rating is key, also consider:

  • Sachet Material: Ensure the sachet is made of food-grade, porous material that allows oxygen and moisture to enter but prevents the contents from leaking.
  • Absorption Speed: Some applications require faster oxygen removal than others. Consult with our technical team to understand the absorption kinetics of different products.
  • Quantity per Package: Depending on the size of your packaging and the desired level of protection, you might use a single larger absorber or multiple smaller ones.
