Oxygen Absorber / Oxygen Scavenger

Problem: Pastries are prone to lipid oxidation, mold growth, and quality deterioration during storage due to the presence of oxygen.

Solution: An iron-based oxygen scavenger is placed inside sealed packaging. Effects:
• Reduces oxygen concentration in the package (often below 0.1%)
• Prevents mold growth
• Extends shelf life (for example, from 15 days to 3–6 months)
Typical products: mooncakes, bread, biscuits, and nuts.

Problem: Meat products can oxidize, discolor, and develop off-flavors during storage.

Solution: An oxygen scavenger is added to vacuum-packed or nitrogen-flushed packaging. Effects:
• Maintains stable product color
• Prevents fat oxidation
• Inhibits bacterial and mold growth
Typical products: beef jerky, dried meat snacks, and cured meat products.

Problem: Oxygen exposure causes aroma loss and quality degradation in tea and coffee products.

Solution: A small oxygen scavenger sachet is added inside aluminum foil laminated pouches or other high-barrier packaging. Effects:
• Preserves aroma and flavor
• Reduces oxidation-related quality loss
• Improves storage stability
Typical products: green tea, oolong tea, black tea, roasted coffee beans, and ground coffee.

Problem: Certain active ingredients in medicines and supplements are sensitive to oxidation and may lose efficacy over time.

Solution: Oxygen scavengers are inserted into bottles or pouch packaging where appropriate. Effects:
• Improves ingredient stability
• Helps preserve efficacy
• Enhances storage safety
Typical products: herbal medicines, capsules, tablets, and nutraceutical powders.

Problem: Electronic components may suffer oxidation or corrosion on metal contacts during storage and transportation.

Solution: Oxygen scavengers are used together with anti-static or barrier packaging systems. Effects:
• Protects metal contacts from oxidation
• Improves reliability of sensitive components
• Extends safe storage duration
Typical products: connectors, sensors, PCB assemblies, and precision metal parts.

Oxygen scavengers are mainly used to lower the oxygen level inside packaging, thereby preventing oxidation, inhibiting mold growth, preserving freshness, and extending product shelf life. They are widely applied in food, pharmaceuticals, agricultural products, and electronics.
