Food Oxygen Absorber Sachets

What is Food Oxygen Absorber?

Food oxygen absorber, also known as a food-grade oxygen scavenger or deoxidizer, is an active packaging technology that removes residual oxygen from sealed food packaging. Unlike desiccants, which control moisture through physical adsorption, oxygen absorbers work through a chemical reaction — the iron powder inside reacts with oxygen and moisture in the air (Fe + H2O + O2 → Fe(OH)3), gradually converting available oxygen into a stable iron oxide. This creates a low-oxygen environment inside the package, helping prevent oxidation, mold growth, and pest infestation. For a broader look at moisture and freshness control technologies across our product range, see our article on Silica Gel Desiccant: Applications and Industry Insights.

Benefits

• Effective oxygen removal — absorbs over 6 times its own volume in oxygen, helping create and maintain a low-oxygen environment inside sealed packaging
• Prevents spoilage — helps inhibit mold growth, rancidity, and oxidative degradation that shortens shelf life
• Wide temperature range — remains effective from -5°C to 40°C, suiting a range of storage and shipping conditions
• Flexible sizing — available in cc-capacity models from 10cc to 1500cc, letting you match the right capacity to your package size
• Flexible format — available as individual sachets or continuous strips for different production line setups

Applications

Food oxygen absorber sachets are used across a wide range of food preservation applications:

• In dry packaged foods like rice, beans, grains, pasta, and flour, they help prevent oxidation and pest infestation during long-term storage.
• In snack foods such as chips, nuts, trail mix, and dried fruit, they help preserve flavor, color, and texture.
• In dried meats and seafood, they help prevent rancidity and extend shelf life.
• In baked goods, they help inhibit mold growth and maintain freshness.
• In herbs, spices, coffee, and tea, they help preserve aroma and prevent flavor loss.
• In ready-to-eat meals and long-term food storage, they support extended shelf life for emergency preparedness and bulk storage needs.

FAQ

Q1: Is a food oxygen absorber a food additive? No, it is not a food additive. It is a packaging aid placed inside the package (not in direct contact requirements like an ingredient) to remove oxygen from the sealed environment.

Q2: How do I choose the right model size? The right cc-capacity model depends on your package or container volume — larger containers generally require higher-capacity absorbers. Contact our team with your packaging specifications for a tailored recommendation.

Q3: Can I use more than one oxygen absorber in a package? Yes, using more than the minimum required amount is safe — oxygen absorbers only react with available oxygen and will not affect food if the package contains more absorption capacity than needed.

Q4: What is the minimum order quantity? MOQ is based on the model and quantity required for your application. Please contact our team for a tailored quote.
