What else can I help you with?
Why are my oxygen absorbers hot when I use them for food storage?
Oxygen absorbers get hot when used for food storage because they undergo a chemical reaction that releases heat as they absorb oxygen to help preserve the food and prevent spoilage.
Do oxygen absorbers expire?
Yes, oxygen absorbers do expire. Over time, they lose their effectiveness in absorbing oxygen, which can impact their ability to preserve food and other products. It is important to check the expiration date on oxygen absorbers and replace them as needed to ensure they work properly.
How long do oxygen absorbers last before they need to be replaced?
Oxygen absorbers typically last about 1-2 years before they need to be replaced.
How long does it take for oxygen absorbers to work in preserving food freshness?
Oxygen absorbers typically start working immediately upon contact with air, removing oxygen from the packaging to help preserve food freshness. The effectiveness of oxygen absorbers can vary depending on factors such as the type of food and packaging used.
How long do oxygen absorbers last once opened and exposed to air?
Oxygen absorbers typically last for about 30 minutes once opened and exposed to air before they lose their effectiveness.
How long does it take for oxygen absorbers to work effectively in preserving food freshness?
Oxygen absorbers typically take about 24 to 48 hours to work effectively in preserving food freshness.
How long does it take for oxygen absorbers to work effectively?
Oxygen absorbers typically start working within a few hours, but it may take up to 24 to 48 hours for them to reach their maximum effectiveness in removing oxygen from a sealed container.
How long are oxygen absorbers effective for preserving freshness in food storage?
Oxygen absorbers are effective for preserving freshness in food storage for about 6 months to 2 years, depending on the type and quality of the absorber.
Can you store rice and oats in 275 gallon totes with oxygen absorbers just dont have that much luck with mylar bags can i store the rice and oats in a 275 gallon food grade tote with o2 absorbers?
Yes, you can store rice and oats in 275 gallon totes with oxygen absorbers.
How can you determine if oxygen absorbers are still effective?
To determine if oxygen absorbers are still effective, you can check if they are still pliable and have not hardened. Additionally, you can perform a simple test by placing the oxygen absorber in a sealed container with a small amount of water and observing if it creates a vacuum seal. If it does, then the oxygen absorber is still effective.
How hot do HotHands get when activated?
When activated, HotHands can reach temperatures of up to 135 degrees Fahrenheit.

Oxygen Absorber Packets | Oxygen Absorbers For Food Storage | Cilicant We are leading oxygen absorber packets supplier, which are ideal for food storage for longer preservation, absorbing 98% of oxygen from the product - oxygen absorbers for food Oxygen Absorbers Little iron powder and salt packets called oxygen absorbers are used to extend the shelf life of food. To avoid color fading, they are utilized in food packaging. Prevent infestation, aid slow the growth of microbes like fungus, and keep oils from going rancid. By absorbing oxygen, these packets efficiently lower the oxygen concentration in the aerobic atmosphere to 0.01%. The iron in an oxygen absorber turns to rust when exposed to moisture from the air and food, which reduces the amount of oxygen present (a process known as "oxidation"). A larger concentration of nitrogen is produced as a result of the change in oxygen content, which is preferable for products with lengthy shelf lives. Oxygen absorbers are little packets of iron powder packaged in a material that keeps the iron in, but allows oxygen and moisture to enter and be absorbed. The iron absorbs the oxygen causing the iron to rust. As it rusts, or oxidizes, it absorbs any oxygen that may be present. Advantages of oxygen absorbers: • Extend the shelf life of products • Prevent oxidation • Prevent food damage from infestation of insects • Inhibit growth of aerobic pathogens such as: molds, mildew and bacteria. • Significantly improve keeping qualities of polyunsaturated fats and oils • Delay the discoloration in foods • Eliminate the need for additives such as sulfur dioxide, BHA, BHT, sorbates, etc. • Foods are not crushed or squeezed • Prevent oxidation of vitamins A, C and E • Easy to use Why do I need Oxygen Absorbers? Oxygen and moisture are two factors that destroy the value of dehydrated and freeze-dried foods. Theses elements have a detrimental effect on color, flavor, vitamin content, and fats of stored foods. Oxygen will enhance the growth of insects, bacteria, mold, and yeast in your food, accelerating spoilage. Oxygen absorbers help to remove the oxygen in your container, leaving nitrogen. Dry foods are protected against spoilage and bacteria growth in a nitrogen environment. A “nitrogen flush” is often used to force the oxygen out of a product before it is sealed for storage. But even when a nitrogen flush has been done, it's still wise to include an oxygen absorber inside the container to help eliminate any remaining moisture. During the freeze-drying or dehydrating process, much of the moisture causing molding or spoilage is eliminated. An oxygen absorber will help to mitigate any moisture that remains once the food is packaged. Foods with a high moisture or oil content should not be stored in reduced oxygen packaging because it can cause botulism poisoning. Only store foods with in low moisture (10% or less) with oxygen absorbers. Oxygen absorbers actually remove oxygen more effectively than vacuum packaging because they only remove the oxygen rather than all the air. How Does Oxygen Absorber Work? When an Oxygen Absorber is instituted correctly, it absorbs moisture to a minor degree (atmospheric moisture) and mostly oxygen. Typically most commercial oxygen absorbers are composed of black powder which is a mix of ferrous carbonate, activated carbon, calcium carbonate/ salt (white specks seen), and some moisture as well (self activated oxygen absorber). Once the moisture is absorbed onto the activated carbon, the ferrous carbonate in close proximity is oxidized to ferric carbonate (i.e. rust). Prior to implementing the oxygen absorber, the total atmospheric air volume contains 20.90% oxygen at sea level (1 atmosphere of pressure). Volume is measured in cubic centimeters (cc)/ milliliters (mL). The oxygen absorber reduces the oxygen concentration of the inside of the container/ modified atmospheric packaging to 0% (effectively nitrogen flushing the product) (i.e. 300cc oxygen absorbing satchel used; assuming that there is 300mL oxygen in the food packet or container or 5 x 300mL of total atmospheric air headspace = 1500ml (cc) of air). Thus, the nitrogen concentration of the inside of the container will then become 99.6%, carbon dioxide should be still 0.3% and others 0.1% thus inhibiting the growth of aerobic organisms such as aerobic fungi/ mold. This to some degree mimics nitrogen flushing, however another important and unique principle applies. The oxygen absorber will continue to absorb oxygen in the presence of packaging that has a high OTR (oxygen transmission rate) and also any micro-leaks that maybe present.
