One of my favorite ways to store flour long term is to vacuum seal it in mason jars. Vacuum sealing flour extends the shelf life for up to a year. We are told that pre-ground flour loses its potency after just a few months, so finding ways to extend its shelf life is beneficial. Although, I have used pre-ground flour a year after its expiration date in its original packaging and it worked just fine for my baking projects. Vacuum sealing flour ensures that your flour won’t be infested with bugs and because air is taken from its storage container, it will stay fresher longer!

How do you vacuum seal flour?
There are two methods for vacuum sealing flour: vacuum sealing in the jar (my favorite method) or vacuum sealing in brown paper bags. I did both of these methods in my vacuum sealing video but this blog will focus on vacuum sealing dry goods in jars. The purpose of vacuum sealing in brown paper bags would be for measuring flour ahead of time for recipes so then you can grab a vacuum sealed flour bag and already have the amount of flour ready to go. With jars, you will have to re-seal each time. Vacuum sealing jars takes no time at all, so I don’t mind doing that.
Here are the steps for vacuum sealing dry goods:
- Pour the contents into a clean jar.
- Place a lid on top of the jar (not the ring) JUST the lid
- Place the lid accessory attachment on top of the lid
- Hook the accessory port up to the lid accessory and follow the instructions on how to vacuum seal with your sealer’s accessory port. Mine, I click “hand held” and it begins the process
- Remove the lid accessory and lift the jar by the lid with your fingers to check to see if it is sealed
- To ensure a seal, twist a jar ring around the lid so the lid stays sealed. Date and name the jar.
This process does not replace canning. Canning is a special process of heating food then using the lid’s sealing mechanism to seal the jar. Vacuum sealing just removes the air.

What foods can be vacuum sealed?
You don’t want to vacuum seal soft cheese, raw garlic or onions, raw bananas, broccoli, cabbage, arugula, and cauliflower.
Soft cheeses become susceptible to mold if they are stored in the airless environment that vacuum sealing creates. This will make your cheeses go bad quickly, so it’s best to just store these in the fridge unrestricted from air.
Raw garlic and onions, broccoli, cabbage, arugula, and cauliflower emit gasses after they have been chopped or opened. Because of this, they can cause the bag to inflate after they have been vacuum sealed and this will make them go rancid fast. It is best to store these in an environment with airflow.
If you want to vacuum seal bananas, the best way to do this is to freeze the bananas first, then vacuum seal them and store in the freezer. These can be used for smoothies or yogurts or other baking dishes.
