| Commonly asked questions on the subject of using oxygen absorbers in food applications. |
| 1.What is an oxygen absorber made of? |
Oxygen absorbers, also called oxygen scavengers, are chemical mixtures packed in the form of sachets or packets in a plastic film. The chemical ingredient has a chemical reaction with oxygen molecules to form an oxidized compound, removing free-forms of oxygen molecules from the surrounding environment.
The chemical mixture in OxyFree oxygen absorber sachets has an active ingredient of iron powder (Fe) in most formulas. Alternative OxyFree absorbers have an active ingredient of Vitamin C. |
|
| 2.Is OxyFree toxic? |
Our OxyFree sachets are completely safe. While they are not edible, they are non-toxic. The acute oral toxicity testing on mice shows the LD50 > 5,000 mg/kg body weight. |
|
| 3.Does the OxyFree sachet emit any gas inside of the food packaging? |
No harmful gases are emitted from the OxyFree sachet. One formula emits CO2 intentionally for certain food applications, but OxyFree sachets will not alter the smell or taste of the product they are packaged with. |
|
| 4.Why use OxyFree? |
When food is in an environment containing oxygen, even as low as 0.5%, it can spoil or develop mold over time. The food ingredients may become oxidized, causing the color or freshness to change while microorganisms can thrive and alter the desired food taste.
By using OxyFree sachets to maintain an oxygen-free environment, food can keep its freshness, taste and color for a much longer period of time. |
