Discover the benefits of using oxygen absorbers to keep your food storage fresh and free from contaminants for years to come.
What Are Oxygen Absorbers?
An oxygen absorber (O2 absorber) is a small packet containing food-safe iron oxide that removes oxygen from the air through a chemical reaction. By reducing oxygen levels in your storage containers, O2 absorbers help prevent contamination from water, bacteria, and insects. This ensures your food stays fresh for longer periods.
Understanding O2 Absorber Sizes
O2 absorbers are measured in cubic centimeters (cc), which indicates the volume of oxygen they can absorb. For example:
- A 2000 cc absorber can remove 2000 cc of oxygen.
- A 500 cc absorber can remove 500 cc of oxygen.
The size of your container will determine which size of O2 absorber you need.
Choosing the Right O2 Absorber for Your Food
Different foods require different sizes of O2 absorbers due to their density:
- Dense foods like flour and rice contain less air and require smaller absorbers.
- Less dense foods like pasta and beans have more air space, requiring larger absorbers.
Refer to the chart below for guidance on selecting the right O2 absorber based on container size and food type.
Using O2 Absorbers Effectively
Follow these best practices when using oxygen absorbers:
- Avoid using with certain foods: Do not use O2 absorbers with sugar or salt, as they may clump.
- Work quickly: Once opened, O2 absorbers should be used within two hours, as they begin absorbing oxygen immediately.
- Ensure proper sealing: Place absorbers in your containers and seal them tightly for maximum effectiveness.
Properly stored, dry foods with O2 absorbers can last up to 25 years.
Preserve Freshness for Years
Whether you're storing bulk ingredients or creating your own freeze-dried meals, adding O2 absorbers ensures long-lasting freshness. Learn more about our Oxygen Absorber Kits to get started today.
