How To Make Oxygen Absorbers For Food Storage

Oxygen absorbers are a great tool for extending the shelf life of food by removing oxygen from the packaging. This helps to prevent spoilage, preserve freshness, and ensure the quality of your stored food. Making your own oxygen absorbers at home is not only cost-effective but also allows you to have complete control over the ingredients used. In this article, we will guide you through the process of making oxygen absorbers for food storage, step by step.

Materials Needed

To get started, gather the following materials:

  • Iron powder
  • Salt
  • Water
  • Measuring cups
  • Mixing bowl
  • Whisk
  • Small plastic bags
  • Sealing device

Step 1: Measure the Ingredients

The first step in making your homemade oxygen absorbers is to measure the ingredients accurately. For this recipe, you will need to measure the following:

  • 3 parts iron powder: Iron powder acts as the catalyst for oxygen absorption.
  • 2 parts salt: Salt helps to activate the iron powder and improve its effectiveness.
  • 1 part water: Water is crucial for creating the necessary reaction between the iron powder and salt.

Step 2: Combine the Ingredients

Once you have measured the ingredients, it’s time to combine them in a mixing bowl. Follow these steps:

  1. Pour the iron powder into the mixing bowl.
  2. Add the salt to the mixing bowl.
  3. Pour the water into the mixing bowl.
  4. Whisk the mixture until well combined.

It is important to ensure that all the ingredients are thoroughly mixed to create a uniform blend.

Step 3: Prepare the Bags

After the ingredients are well combined, it’s time to prepare the small plastic bags for the oxygen absorbers. Here’s what you need to do:

  1. Take a small plastic bag.
  2. Spoon the mixture into the bag, filling it about three-quarters full.
  3. Seal the bag tightly, ensuring that no air can escape.

Proper sealing is essential to maintain the effectiveness of the oxygen absorbers.

Step 4: Test the Absorbers

Once you have prepared the oxygen absorbers, it’s important to test their effectiveness before using them for food storage. Follow these steps:

  1. Place one of the absorbers in a container with food that you wish to store.
  2. Seal the container tightly to create an airtight environment.
  3. Leave the container undisturbed for a few days.
  4. After a few days, check for signs of oxygen absorption, such as a vacuum seal or a deflated bag.

If the oxygen absorber has created a vacuum seal or if the bag appears deflated, it indicates that the absorber has successfully removed oxygen from the container.

Step 5: Use and Store the Absorbers

Once you have tested the effectiveness of the absorbers, you can start using them for food storage. Follow these guidelines:

  1. Place the oxygen absorbers in food storage containers along with the food.
  2. Ensure that the containers are airtight to prevent oxygen from entering.
  3. Store the remaining absorbers in airtight containers to maintain their effectiveness.
  4. Label the containers with the date of creation for reference, as the absorbers tend to lose their effectiveness over time.

Properly stored food will have a longer shelf life, and your homemade oxygen absorbers will help maintain its freshness and quality.

Important Tips

While making and using oxygen absorbers for food storage, it is crucial to keep the following tips in mind:

  1. Use appropriate safety precautions when handling iron powder to avoid accidental ingestion or contact with skin or eyes.
  2. Keep the oxygen absorbers out of reach of children and pets, as they can pose a choking hazard if consumed.
  3. Discard any absorber that shows signs of moisture or damage, as it may not be effective in removing oxygen.

By following these important tips, you can ensure your safety and the effectiveness of your homemade oxygen absorbers.
