    The 500cc oxygen absorbers work great for long term food storage. Very satisfied.

  2. Rock hard packages 5 Star Review

    Posted by on 28th Nov 2020

    Use these absorbers with Mylar foodsaver compatible bags. After a day or two the package is hard as a rock. I expect if the bags stay sealed, they lack of light and oxygen will provide me with the long term food security I’m after.

    Fast shipping

Oxygen absorbers are also known as oxygen packets or oxygen scavengers.

Remember the acronym MOLT when you are thinking about your food storage:  the four enemies of long-term food storage are Moisture, Oxygen, Light, and Temperature.  Using Mylar Bags and Oxygen Absorbers inside a 1, 2 or 5 gallon bucket is your best defense against these enemies.

Oxygen absorbers are made of a chemical compound, the active ingredient of which is a powdered iron oxide. Our absorbers are completely safe. While they are not edible, they are not toxic. No harmful gases are created, and the oxygen does not remove the fresh smell and taste of the product.

 What are the main benefits of using an Oxygen Absorber? 

Simply put: Oxygen Absorbers will PROTECT Your Long Term Food Storage.

Here are the main benefits of using our Oxygen Absorbers:

  • Keeps the freshness and original taste, smell, and color of your stored food items.

  • PREVENTS the growth of mold, mildew, bacteria, aerobic pathogens, spoilage organisms, and anaerobic microorganisms.
  • Dramatically EXTENDS your Product's SHELF LIFE
  • Emits NO harmful gases or bi-products.
  • Are FDA approved for direct contact with food and related products?
  • Eliminates the need for unhealthy preservatives such as Sorbates, Benzoates, BHA, BHT, Sulfur Dioxides, and etc.
  • Works well with vacuum packaging or gas flushing to even further absorb any already oxygen sealed inside or that may eventually permeate the package.
  • Helps keep the nutritional qualities of polyunsaturated oils and fats.
  • Prevents the oxidation of your food's A, C, and E Vitamins
  • Works well with dry or semi-moist foods
  • Great for Grains, Legumes, Beans, Nuts, Seeds, Dried Meats, Jerky, Milk Powder, Baking Mixes, Flours, Sugar, Salt, Spices, Seasonings, Herbs, Coffee, Tea, Candies, Confectionaries, Snacks, Breads, Cakes, Cookies, Pastries, Pasta, Pharmaceuticals, Vitamins, Supplements, Bird Seed, Pet Foods, and MANY Other Items
