Oxygen Absorber

After you have dried your vegetables you come to the next step – the proper way to store it.
To store your dehydrated foods, you can use glass jars with steel  screw lids.

Fill up the jar as full as possible and place a oxygen absorber on top of the food and screw on the lid. You can easily make your own oxygen absorber

A oxygen absorbers main goal is to use the oxygen inside the bottle and then create a vacuum. To make this oxygen absorber all that is needed is to add wet salt and steel wool to a material bag. The wet salt causes the steel wool to oxidise (rust), to be able to create rust, oxygen must be present. While the steel wool oxidise it uses up all the oxygen inside the bottle and in the process creates a vacuum where bacteria etc. cannot grow. As soon as all the oxygen is used up, the oxidation (rust) will stop.

What you need:

  • a piece of material of approximately 8 cm x 4 cm
  • Needle and thread
  • a Piece of Steel wool
  • ¼ teaspoon of salt
  • ½ mℓ water

How to make an oxygen absorber:

Cut a piece of material of approximately 8 cm x 4 cm.

Fold over and stitch two of the sides closed.

Tear off a piece of the steel wool and put it inside the little pocket

Wet the salt with the water.

Add the salt to the bag on top of the steel wool.

Sew the last side closed.

Place the oxygen absorber on top of your dried food inside the bottle and screw the lid on.

Depending on the amount of oxygen inside the bottle – it can take up to two days to use up all of the oxygen and create a vacuum.
