Research regarding oxygen absorbers and active packaging see Miltz & Perry 2004, Han 2005, Rooney 2005, Kadoya 2012, Tian et. al. 2013, Realini & Marcos 2014 & Cichello 2015.
Oxygen absorbers sometimes colloquially referred to as ‘Scavengers’, ‘Packets’, ‘O2 absorbers’, or ‘Packs’.
Used for food storage, including
– Walnuts (Jensen et. al. 2003) & Almonds (Mexis & Kontominas 2010)
– Fruit colour stabilizer (Tarr & Clingeleffer 2005)
– CO2 absorbers; strawberries (Aday et. al. 2011; Kartel et. al. 2012)
– Sardines (Suzuki et. al. 1985)
– Pharmaceutical and vitamin products etc., and even as a natural insecticide in stored goods (Tarr and Clingeleffer 2005).
– Sliced wheat bread (Latou et. al. 2010)
– Gluten free bread (Gutiérrez et. al. 2011)
– Rainbow trout fillets (Mexis et. al. 2009)
– Catfish steaks (Mohan et. al. 2006)
– Chicken meat (Mexis et. al. 2012)
– Pork sausages (Martínez et. al 2006)
– Chocolate (Mexis et. al. 2010)
– Milk powder (Thomsen et. al. 2005)
– Meat products (Kerry et. al. 2006)
– Lipid oxidation (Tian et. al. 2013)
– Added to film/ ascorbic acid (vitamin C) (Dave et. al. 1997)
Oxygen absorbers can be added in containers with a high oxygen barrier (i.e. HDPE tubs; packaging [PVdC coated PET/ nylon] or Mylar bags.
OxySorb oxygen absorbers are used by “preppers” to store food in case of natural disasters, with the most common brands are OxySorb and OxyFree (Wholesale Group International), Ageless (Mitsubishi)
Certification
BRC, ISO9001, HACCP and USFDA
Further Use
OxySorb oxygen absorbers can be used with silica gel or clay gel desiccants.
Avaliable Sizes
20cc, 30cc, 50cc, 100cc, 200cc, 300cc, 500cc, 1000cc, and 2000cc.
Calculating Size to Use
The correct sized oxygen absorber cannot be calculated using a “size chart or calculator”.
There are a lot of variables, such as food moisture content, OTR, WVTR, seal width etc.
A lot of websites claim this, but these people are just unqualified and misleading you.
Pet Safety
If a dog or cat has eaten an OxyFree and OxySorb oxygen absorber, they are non-toxic, but as the text states on the absorber “Do Not Eat”; including pets.
However, we cannot comment about other brands.
Microwave Saftey
Do not microwave any food containing an oxygen absorber – discard it immediately.
They are non-toxic, however you should still look for medical care if one is swallowed.
False Advertising
There is a fake company in India impersonating our brand. We have no association with them.
Also beware of authors’ on Youtube claiming the use of heat pads and “ Oxygen absorbers, their dirty little secret exposed“, heat pads are not FDA approved for contact with food and may contain heavy metals.
What is the difference between an oxygen absorber and silica gel?
Both absorb moisture primarily and thus are desiccants, but in a step 2 process, the oxygen absorber also absorbs oxygen. What is the black powder inside? Ferrous carbonate, activated carbon, salt and moisture.
By viewing the indicator color, you can determine the quality or condition of the oxygen absorber. For non-ferrous alternatives, such as vitamin C, contact us. The OxySorb oxygen absorbers are not-reusable but can be recycled as a soil conditioner [IP Australia Patent; 2017204636]. With Oxygen Absorbers and shelf-life, we are the market leaders in innovation and technology.

How Does an Oxygen Absorber Work?
In Summary;
Moisture (catalyst) plus iron powder “ferrous carbonate” (substrate), oxidize (+ oxygen) produce rust.
20.9% –> ~0.2% Oxygen
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%; stoping aerobic bacteria fungi/ mould.
The oxygen absorber will continue to absorb oxygen in the presence of packaging that has a high OTR (oxygen transmission rate) and also any micro-leaks that maybe present.
The advantages of the oxygen absorber satchels versus nitrogen flushing as reported by actual customers include;
Safe; no need for gas cylinders (eg. cylinder hire or extra OHS on site for this product) Accurate; flushing requires quick sealing of the lid (within seconds) versus 1 hour safety window with oxygen absorbers
No capex required; inexpensive, flexible and versitile
