Oxygen absorbers are Little packs of iron powder packed in a substance that keeps the iron in, but allows moisture and oxygen to enter and be consumed. The iron absorbs the oxygen causing the iron to rust. As it rusts, or oxidizes, it absorbs any oxygen that might be present. Oxygen and moisture are Two variables that destroy the value of dried and freeze-dried foods. These components have a detrimental effect on color, flavor, vitamin content, and fats of stored foods. Oxygen will improve the development of insects, bacteria, mold, and yeast on your meals, accelerating spoilage. Oxygen absorbers help to eliminate the oxygen on your container, leaving nitrogen. Dry foods are protected against spoilage and bacteria growth in a nitrogen atmosphere. Anitrogen flush is frequently used to induce the oxygen from a product before it is sealed for storage.

But when a nitrogen flush was done, it is still sensible to include an oxygen absorber within the container to help remove any remaining moisture. Throughout the freeze-drying or dehydrating process, a lot of the moisture causing molding or spoilage is removed. An oxygen absorber will help mitigate any moisture that remains once the food is packed. Foods with a high moisture or oil content shouldn’t be stored in reduced oxygen packaging since it can lead to botulism poisoning. Just store foods with in reduced moisture 10 percent or less with oxygen absorbers. Oxygen absorbers really remove oxygen more efficiently than vacuum packaging since they only eliminate the oxygen rather than most of the atmosphere.

Metallized cans] with Seamed lids, metallized bags, PETE plastic bottles with airtight, screw-on lids, and glass canning jars with metal lids and gaskets do well with oxygen absorbers. Don’t use plastic containers which aren’t identified as PETE or PET beneath the recycling triangle on the bottom of the container. Metallized cans and bags prevent mild, yet another source of spoilage, from reaching your meals with the extra aid of your oxygen absorbers. Oxygen absorber packets come in various sizes, two of the most common are 500cc and 2000cc. To select which size is ideal for you, think about the dimensions of the container you will save your food in and the amount of empty space between the food particles and between the surface of the food and the lid of the container. Some companies that manufacture absorber packets rate them based on their oxygen absorption capacity in millilitres, but others do so from the equivalent air volume the actual total quantity of air between the item pieces.
