Natural Storage Systems

Reshaping the way the world keeps its products


  1. What is it and how does it work?
  2. What are advantages and disadvantages?
  3. What are the Pros and Cons?

Answer: Natural Storage Systems™ is a very unique, yet very old and time tested way of preserving food and other products with “modified atmosphere packaging” or "MAP". (See the USDA memo below) It’s been used commercially since the 1930’s, but never made available in a cost effective and efficient way for the consumer – until now!

To use; simply insert the fold down, stainless steel straw from a Natural Preserve™ canister into the specially designed valve on a Natural Storage Systems™ storage container. Spray an appropriate amount of Natural Preserve™ to modify the atmosphere or place a “blanket” over the product. When using an existing bag with a Snap & Zap Cap™, gently press down on bag and product to force some of the “bad” air out of the bag then spray approximately 1 second to “exchange” the atmosphere inside. Natural Preserve is 100% safe, effective, non-toxic, non-flammable, tasteless, odorless, natural and organic inert gas, extracted and highly filtered - straight from the air you breathe. “Modifying” the atmosphere in a package or container by effectively removing a portion of the oxygen from being in contact with the product – will help reduce oxidation and limit the ability of micro-organism growth and most bacteria from forming. It will also help to reduce freezer burn and bug infestation. INDEPENDENT LABORATORY TESTS HAVE PROVEN THAT USING NATURAL STORAGE SYSTEMS WILL REDUCE DAMAGING OXYGEN LEVELS INSIDE ITS CONTAINERS, thereby extending the shelf life of the contained products. 


  • Very easy to do.
  • Inexpensive to purchase and reorder canisters.
  • Can extend the shelf life of the product.
  • Helps reduce oxidation, bacteria, freezer burn, bug infestation, and micro-organisms from forming.
  • Keeps the product looser in the package, no sticking, clumping or discoloration of product.
  • Recyclable, renewable, natural, completely inert, non-toxic and non-flammable.


  • Without the proper testing equipment, there is no way for the consumer to know the residual oxygen levels of their containers. How much gas or nitrogen to use and the length of time to insert it into the container are both speculation and assumption.

Answer: Natural Storage Systems™ gives a recommended “dosage” of gas to use with the containers for the approximate product applications (typically 1 – 2 seconds depending on the amount of product in the container, type of container and the density of the product (e.g.: chips vs. soup). An amount less than, or greater than, may be speculation, but your actual dosage amount will improve as you continue to use Natural Storage Systems™ and get comfortable with your preferred usage, your specific products and the length of time you would like to keep the product until its next use. Keep in mind, this is not meant to preserve and store your product indefinitely. This is simply a means to extend the shelf life, help reduce food waste and save consumers money by giving the best possible “atmosphere” for storage, similar to the way the product was originally packaged from the manufacturer. Every can of Natural Preserve™ aerosol canister is equal to approximately 100 “squirts” or applications. Natural Preserve is not a substitute for good food handling and storage practices. Refrigerate or store product according to original manufacturers instructions is recommended. 

While this process has been tested and proven to be effective and functional as stated, we can not guaranty individual results with a specific shelf life expiration date. There are many variables by consumers and the product placed inside the container. Bad product in equals bad product out. Accordingly, the purchaser and/or user is responsible for their food or product safety. If the purchaser and/or user does not agree with these terms in any way, please return the product for a full refund. Use of the product is in agreement with these terms.

4. Do you want to rely on guesswork?

Answer: No, this is why Natural Preserve™ gives a recommended dosage on the label, its website and with the Natural Storage System™. Again, you will get a better feel for the process with each use and observing the amounts of spray and type of product being extended in each size of container you are using.  Any amount applied to product is better than no protection at all. For best results, some products, such as meat for example, should have an amount of oxygen left in the container. Recommended amounts of residual oxygen can safely range from a low of < 5% to as high as 60% with only 40% Nitrogen (see #5 below)

5. When removing the straw and sealing the container, will some amount of oxygen will be re-introduced or linger in the container which will affect the modified atmosphere in the container?

Answer: Yes, there could be a small amount of oxygen possibly introduced back into or linger in the container. Remember, the Natural Storage System process is to help extend the shelf life of the product, reduce oxidation, spoilage and bug infestation. However, we can not give expiration dates based on usage or products placed in the container. See notes below on expiration dates. According to the USDA - expiration dates do not refer to or reflect product safety! (see #4 above)

6. To achieve the desired effect of low residual oxygen levels, does this method have many weaknesses?

Answer: Natural Storage Systems™ with “modified atmosphere packaging” is the best way known to date, for storing and preserving your food products and other items, which can be harmed by damaging oxygen and moisture. When you purchase bags of cheese, deli meats, coffee, nuts, many bagged salads, some breads, chips, and others, most are packaged this way directly from the producers - worldwide. Some packages and products come with a moisture absorbing packet, oxygen absorbers or a desiccant to help in this process - controlling moisture and oxygen. However, once you open the package, the protective atmosphere escapes and product decay starts all over again – unless you are using Natural Storage Systems™ and help slow down this process!

There are risks in ANY packaging and re-packaging of open food products. There are no “perfect solutions”. Vacuum sealers have similar results as Natural Storage Systems™ by removing oxygen, except, the initial cost of the equipment is expensive and the single use bags are expensive typically ending up in the landfill somewhere. Basically, vacuum seal bags remove the oxygen from the product in a similar, but costly and time consuming way. And, they do not have the flexibility for repackaging, storing or preserving liquids such as soups, wine and oils, or for preserving breads, chips and many other products that would simply be crushed in the vacuum process. Vacuum sealing can deform products and rob certain products of flavor and freshness. (see #4 and 5 above)

7. What is the air make-up in the Natural Preserve™ canisters, and are they safe?

Answer: The air that we breathe is made up of approximately 78% Nitrogen, approximately 21% Oxygen, and approximately 1% CO2 and Argon with trace elements of other gases. It is not to be inhaled directly into your mouth as direct nitrogen can cause a lack of oxygen to the brain and asphyxiation could occur. However, all blends are a 100% safe, effective, non-toxic, non-flammable, tasteless, odorless, natural and organic gas, extracted and highly filtered - straight from the air you breathe. Our blends are primarily made up of nitrogen (the most commonly used inert gas in food processing). Natural Preserve 100™ is 100% food grade Nitrogen, Natural Preserve 70™ is 70% Nitrogen and 30% food grade CO2, and Natural Product Preserve™ is 100% Nitrogen. All are completely natural and non-GMO

8. I have used wine preservers in the past and they didn't work so well. Is this the same?

Answer: No, this is not the same. The process and gases may be similar, however the difference is - when you spray nitrogen into the wine bottle to "blanket" the wine, it WILL work. Once you spray and push the cork into the bottle you create inside pressure with no place for oxygen to escape, which will allow the oxygen and nitrogen to become mixed and limit the usefulness. The Duckit allows for venting, or purging the oxygen out of the container. With Zip & Zap Bags™ and Snap & Zap Caps™, you simply force residual or excess oxygen out of package prior to applying the Natural Preserve™.
