【Oxygen Absorbers for Food Storage】 are essential to prevent food spoilage during long-term storage. Wisesorb oxygen absorbers use a three-layer packaging material that is safe to come into direct contact with food. It is important to avoid any oil(s) in the package as they can cause oxidation. These oxygen absorbers effectively remove oxygen, reducing the oxygen density to 0.1% or less within 24-48 hours. Simply place them in mylar bags along with your dry goods for optimal results.【500cc Food Grade O2 Absorbers】 are conveniently packaged in 10 packs per vacuum bag, with a total of 5 sets neatly organized and stored in a convenient zipper bag. The outer bag features a zipper for easy storage of unused food grade oxygen absorbers, preventing exposure to air and maximizing their effectiveness. This is a reliable solution for long-term food storage.【Food Storage Oxygen Absorbers】 are essential for preserving the quality and extending the shelf life of various food items. These food-grade oxygen absorbers are especially useful when packaging bottles or Mylar bags for long-term storage. They are highly recommended for use with freeze-dried goods and Mylar bags, ensuring the freshness of dry goods such as moon cakes, pastries, bread, cakes, nuts, popcorn, and other extruded foods.Oxygen absorbers are widely used in various food products, including freeze-dried goods, flour, rice, nuts, jerky, coffee beans, bread, pet food, crackers, pasta, sugar, shredded lettuce, dry canning, rabbit food, timothy hay, alfalfa pellets, and oats. Additionally, they are ideal for preserving the flavor and texture of dried fruits (such as dried longan and wolfberry), dried vegetables, dried seafood (including dried fish and sea cucumber), preserved meats, sausages, and sunflower seeds.Each 500cc oxygen absorber measures 2.36x3.54" and weighs approximately 14 grams, making it a perfect fit for Wallaby 1-Gallon Mylar bags and other airtight containers. These oxygen absorbers are designed to efficiently remove oxygen from long-term food storage containers, preventing oxidation and maintaining the freshness and quality of dry goods. Remember to promptly seal the containers after inserting the oxygen absorbers to maximize their effectiveness.The oxygen absorber utilizes iron powder as its main component. When exposed to air, the iron powder undergoes oxidation, effectively removing oxygen from the food package. It's important to note that when using these absorbers in mylar bags, the bags will not be vacuum-sealed and may only shrink slightly. This is because there is still approximately 20% oxygen in the air, and the absorbers are designed to specifically remove oxygen, not all of the air.
