Can oxygen absorbers be used with canned food? That's a question I get asked a lot as a supplier of Oxygen Absorber Food. Let's dig into this topic and see what the deal is.

First off, let's understand what oxygen absorbers are. Oxygen absorbers are little packets that are designed to remove oxygen from a sealed environment. They're made up of materials that react with oxygen, like iron powder. When these packets are placed inside a container, they suck up the oxygen, creating a low - oxygen environment. This is super important because oxygen can cause all sorts of problems for food. It can make food spoil faster, cause it to lose its flavor, and even lead to the growth of some types of bacteria.

Now, onto canned food. Canned food is already in a sealed environment. The can is supposed to protect the food from external factors like air, moisture, and bacteria. But here's the thing: there can still be a small amount of oxygen trapped inside the can when it's sealed. That little bit of oxygen can slowly start to degrade the food over time.

So, can we use oxygen absorbers with canned food? The short answer is yes, but there are some things to consider.

Benefits of Using Oxygen Absorbers with Canned Food

  1. Extended Shelf Life: As I mentioned earlier, oxygen is the enemy of food preservation. By using an oxygen absorber in a canned food container, we can further reduce the oxygen levels inside. This can significantly extend the shelf life of the food. For example, canned fruits and vegetables might last even longer without the presence of oxygen, maintaining their color, texture, and taste.
  2. Preventing Oxidation: Oxidation is a chemical reaction that occurs when food is exposed to oxygen. It can cause fats to go rancid, vitamins to break down, and the overall quality of the food to decline. Oxygen absorbers help prevent this oxidation process, keeping the food in better condition.
  3. Reducing Bacterial Growth: Some bacteria need oxygen to grow. By removing the oxygen from the canned food environment, we can inhibit the growth of these aerobic bacteria. This is especially important for canned foods that might not have been sterilized to the highest degree or for those that are stored for long periods.

Things to Keep in Mind

  1. Can Integrity: Cans are designed to be airtight. If you're going to use an oxygen absorber, you need to make sure the can is still in good condition. A damaged can might not be able to maintain the low - oxygen environment created by the absorber. Also, if the can has a small leak, the oxygen absorber will work hard to remove the oxygen, but fresh oxygen will keep seeping in, rendering the absorber less effective.
  2. Food Compatibility: Not all canned foods are suitable for oxygen absorbers. Foods that need a certain amount of oxygen to maintain their quality, like some types of fermented foods, might not be a good fit. For example, some canned pickles rely on a small amount of oxygen for the fermentation process to continue in a controlled way. Using an oxygen absorber could disrupt this process.
  3. Absorber Capacity: You need to choose the right size of oxygen absorber for the can. If the absorber is too small, it won't be able to remove all the oxygen in the can. On the other hand, if it's too large, it might create a vacuum that could damage the can.

Types of Oxygen Absorbers for Canned Food

There are different types of oxygen absorbers available, and choosing the right one is crucial.

  • Oxygen Absorber Packets: These are the most common type. They come in various sizes and are easy to use. You can simply place them inside the can before sealing it. Check out our Oxygen Absorber Packets for a range of options.
  • Food Grade 400cc Absorbent Oxygens Pack: This is a specific type of oxygen absorber that has a capacity of 400cc. It's suitable for medium - sized cans. You can find more information about it here.

How to Use Oxygen Absorbers with Canned Food

  1. Prepare the Can: Make sure the can is clean and dry. Check for any dents, rust, or holes that could compromise its integrity.
  2. Choose the Right Absorber: Based on the size of the can and the type of food inside, select an appropriate oxygen absorber.
  3. Place the Absorber: Open the can carefully and place the oxygen absorber inside. Try to position it in a way that it has good contact with the air inside the can.
  4. Seal the Can: Immediately seal the can after placing the absorber. Make sure the seal is tight to prevent oxygen from getting back in.

Conclusion

Using oxygen absorbers with canned food can be a great way to enhance food preservation. It offers many benefits, such as extended shelf life, prevention of oxidation, and reduced bacterial growth. However, it's important to consider the can's integrity, food compatibility, and choose the right absorber.
