Hey there, fellow jerky lovers and food business owners! If you're in the jerky game, you know how crucial it is to keep your product fresh and flavorful. That's where oxygen absorbers come in. As a supplier of oxygen absorbers for jerky, I've seen firsthand how these little packets can make a huge difference in preserving the quality of your jerky. In this blog post, I'll explain how oxygen absorbers work to protect jerky from oxidation and why they're a must-have for any jerky producer.
What is Oxidation and Why is it a Problem for Jerky?
Before we dive into how oxygen absorbers work, let's first understand what oxidation is and why it's a problem for jerky. Oxidation is a chemical reaction that occurs when oxygen comes into contact with certain substances, such as fats and oils. When jerky is exposed to oxygen, the fats and oils in the meat can start to break down, leading to a number of undesirable changes in the product.
One of the most noticeable effects of oxidation on jerky is the development of off-flavors and odors. As the fats and oils in the meat break down, they can produce compounds that have a rancid or stale taste and smell. This can make the jerky unappetizing and reduce its shelf life.
In addition to off-flavors and odors, oxidation can also cause changes in the color and texture of the jerky. Over time, the meat may turn brown or gray, and it may become dry and tough. These changes can make the jerky less appealing to consumers and can also affect its nutritional value.
How Do Oxygen Absorbers Work?
So, how do oxygen absorbers protect jerky from oxidation? The answer lies in their ability to remove oxygen from the packaging environment. Oxygen absorbers are small packets that contain a substance that reacts with oxygen to form a stable compound. When placed inside a package of jerky, the oxygen absorber will start to absorb the oxygen in the air, creating a low-oxygen environment.
There are several different types of oxygen absorbers available on the market, each with its own unique properties and benefits. Some of the most common types of oxygen absorbers used for jerky include iron-based absorbers, non-iron absorbers, and self-indicating absorbers.
Iron-Based Oxygen Absorbers
Iron-based oxygen absorbers are the most widely used type of oxygen absorber for jerky. These absorbers contain iron powder, which reacts with oxygen to form iron oxide (rust). The reaction between the iron powder and oxygen is exothermic, which means that it releases heat. This heat can help to speed up the absorption process and ensure that the oxygen is removed from the packaging environment as quickly as possible.
Iron-based oxygen absorbers are highly effective at removing oxygen from the packaging environment, and they can reduce the oxygen level to less than 0.1%. This low oxygen level helps to prevent the growth of aerobic bacteria and fungi, which can cause spoilage and reduce the shelf life of the jerky.
Non-Iron Oxygen Absorbers
Non-iron oxygen absorbers are a newer type of oxygen absorber that is becoming increasingly popular for use with jerky. These absorbers use a different type of chemical reaction to remove oxygen from the packaging environment, and they do not contain iron powder.
One of the main advantages of non-iron oxygen absorbers is that they do not produce heat during the absorption process. This makes them ideal for use with products that are sensitive to heat, such as jerky that has been flavored with spices or seasonings. Non-iron oxygen absorbers are also less likely to cause discoloration or staining of the product, which can be a concern with iron-based absorbers.

Self-Indicating Oxygen Absorbers
Self-indicating oxygen absorbers are a type of oxygen absorber that includes a visual indicator that changes color when the oxygen level in the packaging environment has been reduced to a certain level. This can be a useful feature for jerky producers, as it allows them to easily monitor the effectiveness of the oxygen absorber and ensure that the jerky is being properly protected.
One of the most popular types of self-indicating oxygen absorbers is the Yome-I Self Indicating Oxygen Absorbers. These absorbers use a patented technology that changes color from pink to blue when the oxygen level has been reduced to less than 0.1%. This makes it easy for jerky producers to quickly and easily determine whether the oxygen absorber is working properly.
Benefits of Using Oxygen Absorbers for Jerky
Now that we've explained how oxygen absorbers work, let's take a look at some of the benefits of using oxygen absorbers for jerky.
Extended Shelf Life
One of the main benefits of using oxygen absorbers for jerky is that they can significantly extend the shelf life of the product. By removing oxygen from the packaging environment, oxygen absorbers help to prevent the growth of aerobic bacteria and fungi, which can cause spoilage and reduce the shelf life of the jerky. This means that jerky producers can store their product for longer periods of time without having to worry about it going bad.
Improved Flavor and Texture
In addition to extending the shelf life of the jerky, oxygen absorbers can also help to improve the flavor and texture of the product. By preventing oxidation, oxygen absorbers help to preserve the natural flavors and aromas of the meat, and they can also help to keep the jerky moist and tender. This can make the jerky more appealing to consumers and can help to increase sales.
Reduced Waste
Another benefit of using oxygen absorbers for jerky is that they can help to reduce waste. By extending the shelf life of the product, oxygen absorbers can help to prevent jerky from going bad before it can be sold. This can save jerky producers money on wasted product and can also help to reduce their environmental impact.
Compliance with Food Safety Regulations
Finally, using oxygen absorbers for jerky can help jerky producers to comply with food safety regulations. Many food safety regulations require that food products be stored in a low-oxygen environment to prevent the growth of harmful bacteria and fungi. By using oxygen absorbers, jerky producers can ensure that their product meets these requirements and is safe for consumers to eat.
Choosing the Right Oxygen Absorber for Your Jerky
Now that you understand the benefits of using oxygen absorbers for jerky, you may be wondering how to choose the right oxygen absorber for your product. There are several factors to consider when choosing an oxygen absorber, including the type of jerky you're producing, the packaging materials you're using, and the desired shelf life of the product.
Type of Jerky
The type of jerky you're producing can have a significant impact on the type of oxygen absorber you should use. For example, if you're producing jerky that has been flavored with spices or seasonings, you may want to consider using a non-iron oxygen absorber to avoid any potential discoloration or staining of the product. On the other hand, if you're producing jerky that is made from lean meat, you may be able to use an iron-based oxygen absorber without any issues.
Packaging Materials
The packaging materials you're using can also affect the type of oxygen absorber you should use. For example, if you're using a high-barrier packaging material, such as a vacuum-sealed bag or a foil pouch, you may be able to use a smaller oxygen absorber than if you're using a lower-barrier packaging material, such as a plastic bag.
Desired Shelf Life
Finally, the desired shelf life of the product can also play a role in the type of oxygen absorber you should use. If you're looking to extend the shelf life of your jerky for several months or even years, you may want to consider using a larger oxygen absorber or a combination of oxygen absorbers. On the other hand, if you're looking to extend the shelf life of your jerky for a shorter period of time, you may be able to use a smaller oxygen absorber.
Conclusion
In conclusion, oxygen absorbers are an essential tool for any jerky producer who wants to keep their product fresh and flavorful. By removing oxygen from the packaging environment, oxygen absorbers help to prevent oxidation, extend the shelf life of the product, and improve the flavor and texture of the jerky.
