Vacuum Sealing Flour

Vacuum Sealing Flour

Vacuum sealing flour is an effective way to keep it fresh for longer periods of time. By removing the air from the packaging, you prevent the flour from coming into contact with oxygen which can cause it to spoil. This method also keeps out moisture and pests, both of which can ruin a batch of flour.

To vacuum seal flour, you’ll need a food sealer and a storage container. Start by scooping the flour into the container, then seal the lid shut. Place the container on the food sealer and activate the machine. Once the seal is complete, store the container in a cool, dry place.

With proper storage, vacuum sealed flour can last for up to two years. That’s much longer than the one to two months you’ll get from storing flour in a pantry. So if you want your flour to stay fresh for as long as possible, vacuum sealing is the way to go.

Should I freeze my flour before vacuum sealing?

You can freeze your flour before vacuum sealing it, but it’s not necessary. Vacuum sealing will protect your flour from moisture and pests, whether it’s frozen or not. If you live in a humid climate or are worried about pests, freezing your flour before vacuum sealing it can give you peace of mind.

How do you seal flour for long term storage?

To seal flour for long term storage, first find a container that is airtight and will keep out pests. A food-grade plastic bucket with a lid is a good option. Next, place the flour in the container and seal it tightly. If you are using a bucket, you can place a layer of plastic wrap over the flour before screwing on the lid. To protect against moisture, you can also place a desiccant packet in the container. Finally, store the sealed container in a cool, dark place.
