What are Oxygen Absorbers and what do they do?

Oxygen Absorbers or Oxygen Absorbing Packets are small packets containing an iron powder formulation that becomes iron oxide in the presence of oxygen, chemically removing and trapping oxygen from its environment at a molecular level. Oxygen Absorbers come in different sizes and ratings, which determine how much oxygen it will absorb and it will continue to absorb until it is full. Because oxygen is destructive to the longevity of food, oxygen absorbers are very useful for many preservation applications such as long-term food storage.  They allow for the removal of oxygen reserves without chemicals or additives which makes this a non-toxic method and categorised by the FDA as GRAS (Generally Recognised As Safe).


The Oxygen Absorber

Because oxygen will gradually trickle into just about any container, using a larger capacity Oxygen Absorber (that can continue to absorb incoming oxygen) will keep it from accumulating and lengthens the storage time. Oxygen Absorbers do not “expire” and will continue to absorb until they are full, even if many years have gone by. What about light? All forms of energy such as light can cause molecular breakdown but light does not contaminate food, it just may have an effect on it's quality. Still, it is best to choose a storage area that is dark and cool. Most food will not be significantly effected by light damage but choosing a dark storage area or using Mylar bags is always the best idea. Even though Oxygen Absorbers used with Mylar bags or mason jars can keep food protected for an astonishing period of time, it is a much better idea to rotate your food supply annually by actually using it.

For more information on the type of storage containers you can use read "Using Oxygen Absorbers in Other Types of Storage Containers and Packaging".


Food Prepping

Food prepping is becoming more popular across Australia with people wanting to prepare themselves and their families for possible future food shortages. Food prepping is also a very convenient, long term food storage option for people living regionally.

These Oxygen Absorbers have been sold in the US since 1992. They have been the top choice of many American businesses for food preservation and packaging for their reliability and other benefits. They absorb 180-300% of their rating as a safety buffer.

NOTE : Once opened, oxygen absorbers must be used immediately, left overs should be vacuum sealed for storage. 

 

Details

These sizes will work for ALL food types*:

  • 50cc for Small (8oz) / 237ml
  • 100cc for a Small (16oz) / 473ml
  • 150cc/200cc for Medium (32oz) / 946ml - the 946ml bags can hold more than 946ml therefore 300cc can be used as well
  • 300cc for a Large (64oz) / 1.89 Litres
  • 500cc for a Extra Large (128oz) / 3.78 Litres
  • 2500cc for a XX Large (639oz) / 18.9 Litres


* Mylar bags must be filled completely. If unsure how many oxygen absorbers to use it is okay to use more absorbers than necessary.

There is a common misconception that a mylar bag should look vacuum-packed when oxygen has been removed. This is false. Just because all the air has not been removed, does not mean that all the oxygen has not been removed. Air consists of 21% oxygen. This means roughly 1/5 of the air volume (oxygen) will be removed, but the remaining 4/5 of inert nitrogen gas, will remain no matter how many oxygen absorbers are used.


The Destructive Effects of Oxygen on Food

 

Oxidation is the process that turns a freshly cut apple brown and turns iron into rust. Not only does oxygen cause the bland, stale taste we all know but it destroys nutrients and supports contamination that occurs from mould, bugs and oxygen-dependent micro-organisms. Oxygen absorbing packets are much better than other preservation methods because they effectively eliminate oxygen and can protect perishables from these effects long-term.
 

Each oxygen absorber pack includes an Oxygen Indicator. For more information on Oxygen Absorbers and Mylar Bags please read the following links: FAQs about Oxygen Absorber Indicators and FAQ's about Mylar Bags and Oxygen Absorbers.

Specifications
Size Options:
  • 50cc - 200 sachets per Packet
  • 100cc - 100 sachets per Packet
  • 200cc - 50 sachets per Packet
  • 300c - 10 sachets per Packet
  • 500cc - 10 sachets per Packet
  • 2000cc - 10 sachets per Packet

* Mylar Bags must be filled completely. Food types can be deceiving and may contain far more air than you thought therefore it is okay and a great idea to use more absorbing power than necessary . Flour can be 50% air ! Pastas can be 75% air ! A larger capacity Oxygen Absorber will help account for this. If there was a tiny leak in the seal, a larger absorber will continue to absorb oxygen for many years.

Oxygen Absorption Required for Common Foods

Oxygen Absorbers for Long Term Food Storage. To ensure adequate oxygen absorption is used for long term preservation of foodSurvival Supplies Australia recommends mylar bags should be filled completely & food packed tightly. There is nothing wrong with using more oxygen absorbers than necessary. If you are unsure of the quantity of oxygen absorbers needed, always go with a higher quantity. Oxygen Absorbers from PackFreshUSA will absorb 180% to 300% of their rating to have a substantial buffer of safety.

Note: like flour and powdered mixes consist of very fine particles, they can contain a surprising amount of air. Be aware that 300cc oxygen absorption quantity per 3.8 litres isn’t enough for food types like pasta. Remember is it okay to use MORE absorbers than necessary, if unsure.
