Many preppers swear by high-quality oxygen absorbers for preserving food because they can extend the shelf life of dry foods like grains, nuts, and legumes by up to five times longer than their original packaging date. They also work wonders for preventing freezer burn in frozen foods without affecting taste or texture. These little guys are a budget-friendly way to prevent spoilage, though the quality can vary quite a bit. When it comes to the best oxygen absorbers for food preservation, there’s one brand that really stands out for its effectiveness and value.
Before oxygen absorbers became widely available, keeping food fresh was a real challenge. Oxygen is essential for life, but it also causes food to spoil quickly. Now that we know how crucial oxygen absorbers are for food storage, there are a few things you should keep in mind before purchasing them.
Oxygen absorbers are a great tool to help keep your food fresh for longer. You can use them in different ways, like vacuum-sealing them inside packaging or adding them to mason jars. They offer plenty of benefits for food storage, but only if you choose the right ones. In this guide, we’ll dive into what makes a good oxygen absorber, how to use them properly, and where to find the best ones available today!

How to Choose the Best Oxygen Absorbers for Food Storage
If you’re looking to keep your food fresh and free from spoilage, oxygen absorbers are your best friend. These little packets do exactly what the name suggests—they absorb the oxygen around your food, which helps protect it from the bacteria and fungi that cause spoilage. By removing most of the oxygen in your storage containers, you can extend the shelf life of nearly any type of food, whether it’s dry or moist. They’re a great solution for long-term food storage, ensuring that your food stays fresh and nutritious for months or even years.
Oxygen removal is key when it comes to preserving high-quality foods like dried fruits, grains, or even jerky treats for your pets. While oxidation can cause things like apples and potatoes to brown, it also leads to the loss of nutrition, flavor, and color in foods like nuts, beans, and even pet treats. The best part? Oxygen absorbers work naturally by using a chemical compound that doesn’t contaminate your food in any way. Depending on the size of the product you're storing, these packets can last anywhere from 1 to 3 years, making them a reliable tool for your pantry.
Choosing the right oxygen absorber can be a bit tricky with so many options on the market, but with this simple guide, we’ll help you figure out which one is best for your needs.
1. Size
The first thing to consider is the size of the oxygen absorber. The size you need really depends on what you’re storing. You can find oxygen absorbers ranging from small individual packets to large units that can absorb up to 2500cc of oxygen. If you're storing moisture-sensitive foods, look for packets with moisture indicators to let you know when it's time to replace them. This helps you avoid guessing when to buy more!
2. Packet
Next, think about how much oxygen needs to be absorbed. For example, if your storage container needs to remove 5% of its oxygen, you’ll need to choose a packet that can handle that amount. To calculate, consider the size of your container and the volume of food inside. If you have a 10-inch diameter container that holds 800 cubic inches of food, you’d need a packet that absorbs at least 40cc of oxygen. The right size packet will help you seal your food properly and keep it fresh.
3. Moisture
If you’re storing moist foods like jerky, nuts, or pastry powders, you'll need to think about moisture as well. Many oxygen absorbers come with a moisture indicator, but it’s important to note that you shouldn’t use these packets unless your food is properly dehydrated. Moisture can interfere with the effectiveness of the oxygen absorber, so it’s best to remove excess moisture before sealing your food.
4. Food Type
Oxygen absorbers are made with a mix of iron powder, salt, activated carbon, and sometimes an indicator to show when they’ve done their job. There are specific absorbers designed for dry or moist foods, and some even work with nitrogen-flushed containers. If you’re storing something particularly delicate, you might want to choose an absorber with multiple indicators so you can check the status without opening the container.
5. Shelf Life
Like most products, oxygen absorbers have a shelf life, but they last a lot longer if stored in a cool, dry place in an airtight container. While most packages will list a “best if used by” date, they can often last for years if stored properly. Just keep in mind that once you open the package or expose the absorbers to humidity, their shelf life starts to shorten quickly.
6. Indicators
There are two main types of indicators you’ll find on oxygen absorbers. Some use a moisture indicator, which changes color to show when the absorber is working. Others use ink that changes from blue to pink to signal that the oxygen has been absorbed. These indicators make it easy to tell when it's time to replace the absorber, so you don’t have to guess.
7. Grams of Oxygen Absorbed Per Gram of Packet
When you’re looking at oxygen absorbers, don’t just focus on the price—also consider how much oxygen the packet can absorb. For example, cheaper packets might only absorb 1/2cc of oxygen, while more expensive ones might absorb 4cc. While the 4cc packet might seem like a better deal, you’ll need almost twice as many to get the same result. So, in the long run, it’s better to pay a little more for a higher-quality packet that gets the job done with fewer packets.
8. Price
Oxygen absorbers are generally pretty affordable, but the price can vary depending on the features. For example, multi-indicator or moisture-resistant packets may cost a little more upfront, but they can save you money in the long run because they can be reused. It’s all about finding the balance between price and quality for your needs.
9. Quality Assurance
Finally, always check where the oxygen absorbers are made and what materials are used in their production. Some cheaper options might come from overseas and use questionable ingredients that could affect the quality of your food. Stick with trusted brands and look for certifications to ensure you’re getting a safe, effective product.
Moisture Absorbers vs Oxygen Absorbers for Dehydrated Foods
Frequently Asked Questions
1. How long does food last with oxygen absorbers?
Oxygen absorbers are pretty effective when it comes to extending the life of your food. When packaged, they last anywhere from 6 months to a year before being opened. Once you open the package, though, you’ll want to use them within 15 minutes or, at most, within 3 days. If you have any leftover packets, store them in an airtight glass jar, and they’ll last for up to 6 more weeks. They’re still good for at least another 3 months if kept cool!
2. What foods Cannot be stored with oxygen absorbers?
Oxygen absorbers are great for keeping dry foods like herbs and spices fresher longer. But there’s a key difference between an oxygen absorber and a delay pack. Some foods, like those that are sensitive to moisture or need a little extra protection from things like metal utensils or plastics, shouldn’t be stored with oxygen absorbers. The oxygen can interact with certain materials, leading to spoilage or changes in color, so it’s best to be cautious with these.
3. Can oxygen absorbers cause botulism?
Botulism is a nasty illness caused by bacteria, and it can show up in both canned and dry foods. This happens when there’s too much moisture trapped in the food, even after sealing it up. The moisture creates a perfect environment for botulism and other illnesses. So, while oxygen absorbers help with food freshness, you still need to make sure your food is properly dehydrated to avoid moisture buildup.
4. Can you put oxygen absorbers in flour?
Absolutely! If you’re looking to store flour for the long haul—whether it’s months, years, or even decades—oxygen absorbers are your best bet. When used with sealed Mylar bags, they’ll keep your flour safe from moisture and insects, ensuring it stays fresh for as long as possible.
5. Do you need oxygen absorbers if you vacuum seal?
Oxygen absorbers can be a great addition to vacuum sealing. While vacuum sealing does a good job of removing air and sealing out bacteria, adding an oxygen absorber takes it a step further. It helps prevent mold and bacteria from growing, making your food last up to 10 times longer than it would without it. This is especially helpful for meats and vegetables!
6. Do oxygen absorbers remove moisture?
Oxygen absorbers only absorb oxygen, not moisture. If you need to control the humidity levels in your storage, you’ll want to use something like Silica Gel. This will keep moisture at bay while the oxygen absorbers do their job.
Conclusion
Oxygen absorbers are a game-changer when it comes to food storage. They’re affordable, effective, and perfect for extending the shelf life of dry goods like grains, nuts, and legumes—sometimes up to five times longer than the original packaging date! Whether you're prepping for the long term or just trying to avoid wasted food, oxygen absorbers help keep your pantry stocked with fresh, safe food. They work by trapping excess air inside packages, which slows down the growth of bacteria and keeps your food fresh longer. If you’re looking for a reliable tool to preserve your food, oxygen absorbers are definitely worth considering.
So, now that you know what to look for, go ahead and get the best oxygen absorbers for your food storage needs—you won’t regret it!
