Oxygen Absorbers remove oxygen from sealed containers. Taking the air out stops oxidation.. and extends shelf life. Eliminating oxygen prevents insects.. that could be in the food when it’s sealed. The following is what you need to know about Oxygen Absorbers.
• Absorbers are non-toxic and food safe. (ingredients: iron and salt).
• Two 500cc absorbers are enough for a 5-6 gallon bucket.
• The less dense the food item.. the more absorbers you need.
• Altitude affects the air density. If you live on a mountain.. you can use fewer, if you live at sea level don’t skimp.
• Once you open the bag the absorbers are active, use them as quickly as possible.
• A 500cc pkt. will absorb 500 cc of oxygen from your container.
• They are single-use, and cannot be reused.
• Oxygen absorbers come airtight sealed bags. When you open the bag they begin absorbing oxygen from the atmosphere. They contain enough active ingredients to be open for 30-45 minutes before sealing in your containers. So it's important to have your containers filled and ready for lids before you open the package.
• If you’re not using all the absorbers and want to save the rest for later, re-seal them in an airtight bag using a vacuum sealing machine.
• You can put the absorbers anywhere in the bucket. I put mine on top so I don't lose track of which containers I put them in.
• When using oxygen absorbers in plastic buckets, use standard hammer-on lids. Gamma Lids are airtight, but not designed to counteract the pressure created when the oxygen in the container is removed.
• After the standard lid is removed to use the contents, a Gamma Lid can be used to re-seal the bucket against moisture, rodents and insects. A hammer-on lid (with gasket) will provide an oxygen barrier for a couple of years' storage.
• For longer term storage, you can use Mylar liner bags inside your bucket. When heat-sealed they will block oxygen permeation for years.
•Absorbers in their original sealed bag have a shelf life of 1 year.
