Iron Powder for Oxygen Absorbers

What Are Oxygen Absorbers?

There are many types of Oxygen Absorbers to cover a wide array of applications. Oxygen absorbers are usually a mixture of iron powder, sodium salt (table salt) and activated carbon (charcoal) powder. Iron powder is the primary component, while sodium salt acts as an activator, causing the iron particles to rust, effectively reducing the oxygen level in the surrounding atmosphere to approximately 0.01% when used properly. Activated carbon acts as a gas absorbent and catalyst, further preserving products and removing unsavory odors. While Oxygen Absorbers are not edible, they are not toxic. No harmful gases are created and they do not remove the fresh smell and taste of the product.

What Do Oxygen Absorbers Do?

Oxygen Absorber Packets remove oxygen from airtight containers to below 0.01%, according to Food Industry standards, when used as directed. Upon exposure to air, iron in the packet immediately absorbs oxygen and breaks it down into harmless iron-oxide which is safely contained in the packet and does not contaminate the food.

What Are The Benefits Of Using Oxygen Absorbers?

  1. Extends shelf life
  2. Prevents growth of aerobic pathogens and spoilage organisms, including molds
  3. Eliminates the need for additives such as BHA, BHT, sulfur dioxide, sorbates, benzoates, etc
  4. Significantly improves keeping qualities of polyunsaturated fats and oils
  5. Helps retain fresh-roasted flavor of coffee and nuts
  6. Prevents oxidation of spice oleoresins present in spices themselves and in seasoned foods
  7. Prevents oxidation of vitamins A, C and E
  8. Extends life of pharmaceuticals
  9. Use with gas flushing / vacuum packaging to absorb virtually all oxygen and absorb any oxygen that may permeate the package.

    Typical Applications:
  • Flour and grain items
  • Pasta and noodles
  • Dried fruits and vegetable
  • Spices and seasonings
  • Nuts and candies
  • Coffee and tea
  • Whole fat dry foods
  • Pharmaceuticals and vitamins
  • Medical diagnostic kits and devices
  • Birdseed and pet food
  • Artwork and book preservation
