The oxygen absorber, as the name suggest, absorbs oxygen for food storage, inhibiting fungi and aerobic bacteria and prolonging food shelf-life. A diabsorber absorbs both oxygen and carbon dioxide.

How Does Oxygen Absorber Work?

When an Oxygen Absorber is instituted correctly, it absorbs Oxygen (O2)

Total atmospheric air volume contains 20.90% oxygen at sea level (1 atmosphere of pressure).

– Volume is measured in cubic centimeters (cc)/ milliliters (mL).
– The oxygen absorber reduces the oxygen concentration of the inside of the container/ modified
atmospheric packaging to 0% (effectively nitrogen flushing the product)

(i.e. 300cc oxygen absorbing satchel used; assuming that there is 300mL oxygen in the food packet or container or 5 x 300mL of total atmospheric air headspace = 1500ml (cc) of air).

Thus, the nitrogen concentration of the inside of the container will then become 99.6%, carbon dioxide should be still 0.3% and others 0.1% thus inhibiting the growth of aerobic organisms such as aerobic fungi/ mould.

This theory is the same as nitrogen flushing, but the oxygen absorber removes oxygen more precisely, and furthermore, continues to absorb oxygen even when the packaging allows enter i.e. oxygen transmission rate (OTR) through the packaging itself.

Variables include the OTR, WVTR, seal integrity and the quality of the packaging being used. Oil, Water content and also Protein content of food can affect the shelf life of food as well.

The advantages of the oxygen absorber satchels versus nitrogen flushing as reported by actual customers include;

Safe;         non-toxic, 97% biodegradable, no need for gas cylinders

Accurate;  gas flushing requires quick sealing of the lid (within seconds) versus 1 hour safety window with oxygen absorbers

No capex required; inexpensive, flexible and versitile
