What are Oxygen Absorbers?

Designed primarily to prolong the shelf life of food, oxygen absorbers (or oxygen scavengers) prevent the change of color in food products, stop oils in foods from becoming rancid, and prevent the growth of oxygen-dependent aerobic microorganisms such as fungi and bacteria.

Oxygen supports the growth of microorganisms and can cause color changes and rancid odors in packaged foods. Some kinds of plastic packaging do not have a sufficient foil barrier to exclude oxygen from packaged foods. Oxygen scavengers effectively reduce the aerobic environment to 0% oxygen, thereby preventing the growth of bacteria and fungi and extending the shelf life of a food product drastically. Some products can be vacuum sealed to remove oxygen, but products that are of high value or fragile can be crushed or squeezed in the vacuum process, so oxygen-absorbing sachets are preferred, and are simpler to use.

High quality packaging sealed with reliable equipment is crucial for the effectiveness of the oxygen absorber. A minor packaging fault or leak can render the StayFresh™ packets useless and cause the contents to spoil. Protective flexible packaging requires a high barrier package with a low oxygen transmission rate, such as our Mylar® bags, sealed with dependable sealing machines.
