Instructions for a Handmade Vacuum Jar Sealer

Vacuum sealing your leftovers and other foods keeps them fresh for long-term storage. You can vacuum seal all kinds of foods like popcorn, vegetables, fruits and breads. Vacuum sealing works by removing the air surrounding the food, which slows down the process of spoilage. Commercial vacuum jar sealers can be quite expensive. Luckily, you can make your own vacuum jar sealer at home using some affordable materials you can purchase at your local hardware store.

Create a one-way valve in the lid of a Mason jar (use any size Mason jar). Drill a small hole in the lid of the jar. Wipe off any debris with a towel.

Place a one-way valve with rubber stopper in the hole. You can purchase a one-way valve rubber stopper at your local hardware store.

Clean the jar and lid with liquid soap and water. Wipe the jar dry with a clean paper towel or cloth.

Place the food inside the jar and seal it tight with the lid. Insert the end of the hose of a vacuum hand pump on the outside of the one-way valve. You can purchase vacuum hand pumps at a toy or hardware store.

Remove the air in the Mason jar. Pump or vacuum out the air in the jar until you feel resistance. Push down on the rubber stopper to prevent air from entering the jar.
