Prepare the rice: Ensure that the white rice (or your other dry food items) is clean and dry. Moisture can reduce the effectiveness of vacuum sealing.
Fill the jars: Scoop the white rice into the Mason jars, leaving some headspace at the top. The headspace is necessary for the vacuum-sealing process.
Optional: Add oxygen absorbers: If you have oxygen absorbers, place one or more inside each jar before sealing. This helps in removing residual oxygen that might be present.
Clean the jar rims: Make sure the rim of the jar is clean and free from any rice particles. This ensures a proper seal.
Attach lids and bands: Place the lids on top of the jars and screw on the bands until they are fingertip-tight. Do not overtighten.
Prepare the vacuum sealer: Follow the instructions provided with your vacuum sealer machine to set it up.
Vacuum seal the jars: Place each Mason jar into the vacuum sealer machine and initiate the vacuum-sealing process. The machine will remove the air from the jar and create a tight seal.
Check the seal: Once the vacuum-sealing process is complete, visually inspect each jar to ensure that the lids have sealed properly. Press down on the center of the lids; they should not flex or pop.
Label the jars: It's a good practice to label the jars with the contents and date of sealing.
Store the sealed jars: Store the vacuum-sealed jars in a cool, dark and dry place away from direct sunlight and extreme temperatures to extend the storage life for long term food storage.
