How do I know what size oxygen absorber I need?

This is a rough guide to calculating required oxygen absorber size - it does not take into account the density of the food being stored.

1. Determine the internal cubic dimensions of the package (width x depth x height).
Eg. 5 x 4 x 10cm = 200cm3.

2. Determine the weight of food (in grams) to be packaged.

3. Deduct weight of food from the cubic dimensions of the package.
Eg. 200cm3 - 50gms = 150gm.

4. Multiply the answer by 0.21 (percentage of oxygen in the air) to determine size of oxygen absorber required.
Eg. 150gm x 0.21 = 31.5gm = 30cc oxygen absorber.

How do I use/store oxygen absorbers?

1. Plan your production flow in a way that the oxygen absorber sachets will not be exposed to air for more than 30 minutes.

2. Take the required amount of oxygen absorber sachets from the vacuum sealed bag, remove as much air from the bag as possible and seal/tape closed, then store in an airtight container.

3. The sachets you removed from the bag should be sealed within 30 minutes with the items you wish to protect. Note: it is normal for the sachets to heat up when exposed to air.

Why are oxygen absorbers warm?

When the oxygen absorbers react with oxygen, they become warm. This indicates that they are fresh and are working to absorb oxygen. If the oxygen absorbers are exposed to open air, they may become hot, however when sealed within a package this will not occur.

Why are unopened bags of oxygen absorbers hard?

Due to the vaccum seal, the bag will feel rigid with all oxygen absorbers clumped together. Once the bag is opened, the sachets will separate and should feel like they contain sand.


How do I know if my oxygen absorbers are still good?

The contents of the sachets should feel like sand. If they are hard and crunchy, they've had too much exposure to the air and should not be used.
