Wisesorb 300 cc Oxygen Absorber Packs for Pantry, Food Storage & Vacuum Bags – Food Safe
- Oxygen Absorbers for Long-Term Food Storage: Wisesorb Oxygen Absorbers are designed to help prevent oxidation and food spoilage during long-term storage. Made with a durable three-layer packaging material suitable for food storage applications, these oxygen absorber packets effectively remove oxygen from sealed packages and can reduce oxygen levels to 0.1% or less within 24-48 hours under appropriate conditions. For optimal performance, simply place the oxygen absorbers inside Mylar bags or other airtight containers together with your dry goods and seal promptly. Avoid using with foods containing excessive oils, as oxidation of fats and oils may still affect food quality during storage.
- Product Details: Each 300cc oxygen absorber measures approximately 2.36 × 2.44 inches and weighs approximately 8 grams, making it a convenient choice for 1-gallon Mylar bags and other appropriately sized airtight food storage containers. These oxygen absorbers efficiently reduce oxygen inside sealed containers to help minimize oxidation and maintain the freshness and quality of dry goods during long-term storage. For best results, insert the appropriate number of oxygen absorbers and seal the container promptly to minimize exposure to ambient air
- Resealable Outer Packing: Each package of 300cc food-grade oxygen absorbers comes in an outer bag with a convenient zipper closure, making it easier to store unused packets while minimizing unnecessary exposure to air. Reseal the outer bag promptly after removing the required number of absorbers to help maintain their effectiveness. A practical and reliable solution for long-term food storage, emergency food supplies, and pantry organization.
- Iron-Based Oxygen Absorption: Wisesorb Oxygen Absorbers use iron powder as the primary oxygen-absorbing component. When exposed to oxygen, the iron undergoes an oxidation reaction that captures and removes oxygen from the sealed food package. Please note that Mylar bags may not appear fully vacuum-sealed after using oxygen absorbers and may only shrink slightly. This is normal: oxygen absorbers are specifically designed to remove oxygen rather than all gases inside the package. Nitrogen and other gases remain in the package, so the absence of a strong vacuum effect does not necessarily indicate that the oxygen absorber is not working.
- Ideal for Mylar Bags & Dry Food Storage: Wisesorb Food Storage Oxygen Absorbers help preserve product quality and extend the shelf life of a wide variety of dry foods. These food-grade O2 absorbers are particularly suitable for Mylar bags, bottles, jars, and other airtight packaging used for long-term storage. Ideal for freeze-dried foods and dry goods, including moon cakes, pastries, bread, cakes, nuts, popcorn, and other packaged or extruded foods.
- Wide Range of Food Storage Applications: Oxygen absorbers can be used with a variety of low-moisture foods and dry goods, including freeze-dried foods, flour, rice, nuts, jerky, coffee beans, crackers, pasta, pet food, oats, dry canning products, rabbit food, timothy hay, and alfalfa pellets. They are also suitable for many dried fruits, such as dried longan and goji berries, as well as dried vegetables, dried seafood, preserved meats, sausages, and sunflower seeds. By reducing oxygen inside sealed packaging, these oxygen absorber packets help protect the flavor, texture, and overall quality of stored products.
