ore Flour For The Long Term

Flour is considered a non-perishable food.  However, if you don’t store flour properly, it will go bad.  Here’s what you need to know about flour storage and the best options, including for long-term storage.

How to Store Flour Long-Term

In its original paper bag, flour won’t last more than 6 months.  If you move it to an air-tight container, it can last 6 – 10 months. For long-term storage(over 3 months), the best method is Mylar bags with oxygen absorbers.

Why Flour Goes Bad

Just like any dry food, flour can go bad if it is exposed to oxygen, light, moisture, or insects. If you just leave a bag of flour in your pantry, here are some of the problems which can occur that will make the flour go bad.

Mold: Humidity or temperature fluctuations can cause flour to absorb moisture and eventually start to get moldy.  You’ll be able to smell the mold before you actually see it.

Oxidation: Oxidation occurs when oxygen from the air interacts with nutrients in the flour, causing them to break down.  This is particularly a problem with whole-grain flours.  Oxidation will cause the natural oils in the whole-grains to go rancid.

Insects: Even if you store your flour in air-tight containers, you can still get insects like weevils or moths.

How is that possible?

Because flour often already has insect eggs in it when you buy it.  It can take weeks or months for them to hatch depending on the conditions.  Once they do hatch though, you have an infestation which is very hard to get rid of.

Absorbing Smells: Flour can act like a sponge and absorb the smells of whatever is near it.  Have onions next to your flour?  Then the cake you make with it will have an oniony smell too.  You especially don’t’ want to store flour (or any other food, for that matter!) near chemicals like cleaning products.

Best Ways to Store Flour

Below are several flour storage methods.  If you want to store flour long-term (over 3 months), then the best method is Mylar bags with oxygen absorbers.  No other method is truly reliable for long-term flour storage.

Air-Tight Containers

Shelf Life: Approximately 6-10 months

In its original paper package, flour usually won’t last more than 6 months.  If you remove it from the package and put it into an air-tight container, it can last much longer.

One potential problem is that there might already be insect eggs in the flour when you get it.  It can take weeks or even months for the eggs to hatch.  When they do, you will have a nasty infestation which is hard to get rid of.  Thus it’s smart to take steps to kill insect eggs in the flour before storage, such as by freezing or microwaving it first.

Some good flour storage containers include:

  • Mason jars
  • Vacuum sealer containers
  • Air-tight containers like those made by Progressive Prepworks or Rubbermaid’s Brilliance

Freezer

Shelf Life: Indefinitely

If you have room in your freezer, freezing flour is a great way to store it.  It will last forever in the freezer, though you should have a plan in case power outages occur.

To use, remove flour from the freezer and let it get to room temperature.  Note that flour can absorb moisture due to condensation while you bring it to room temperature.  To prevent moist flour, keep the flour in its sealed container – the condensation will collect on the container instead of getting into the flour.

Drying Damp Flour:

If the flour gets damp, you can spread it out on a baking sheet and heat it in the oven at about 200F.  If the flour is very damp, you might need to heat for up to an hour to get it dry.  After drying it, sift it to remove any clumps.

Vacuum Sealing

Shelf Life: 1-2 years

The vacuum sealing process removes air from the packaging. The bags are not completely leak-proof; air and humidity will eventually seep through. However, the reduced amount of air means flour stored this way will last much longer.

Vacuum sealing also keeps insects from getting into your flour.  It will NOT kill insect eggs which are already in the flour though.  That’s why many people first take steps to kill insects in dry food before storage.

To store flour with vacuum sealing:

  1. Place the entire bag of flour into a large vacuum sealer bag. You cannot dump the flour directly into the vacuum sealer bag because the particles of flour will get sucked into the machine.
  2. Follow your products instructions to vacuum seal the flour.
  3. Put the sealed flour in the freezer for at least 96 hours. This is to kill any insect eggs which are in the flour.
  4. If you must remove the flour from the freezer but won’t be using it right away, let it come to room temperature before putting it in any other storage container. Otherwise condensation will form.

Buckets, Plastic Containers or Jars with Oxygen Absorbers

Shelf Life: 5+ years

Oxygen absorbers are little packets of iron which trap oxygen.   If you place OA packets into a food-grade plastic container with flour, it will absorb the oxygen in the container and prevent spoilage from oxygenation.  The lack of oxygen also means that insect eggs can’t hatch.

The problem is that most storage containers are not truly air-tight and will eventually leak.  This includes recycled soda bottles as well as food buckets.

Buckets with gasket lids (see on Amazon) are usually better at preventing air leakage, so are a decent option if you need to store a large amount of flour.

Canning jars also tend to be very reliable and you’ll know the oxygen absorbers have worked because the lid will look “sucked down.”  Just be careful to store jars somewhere cool and dark, as heat and light can also cause spoilage.

Mylar Bags with Oxygen Absorbers

Shelf Life: 10+ years

If you want to store flour for months, years, or even decades, the best solution is to use oxygen absorbers in sealed Mylar bags.

Mylar bags are made from a metal-like material which is impervious to moisture and oxygen.  By sealing flour in Mylar bags with oxygen absorbers, the flour is completely safe from light, moisture and oxygen.  Even insect eggs can’t hatch because there isn’t oxygen in the packaging.

When stored this way, white flour can last 10-15 years.  Whole-wheat flour can last approximately 10 years this way.

Dry Canning – Not Recommended

Dry canning is a process where dry foods like flour are put into canning jars with lids and then heated in the oven.  The heat is thought to sterilize the food and create a seal.  Even though canning jars are used, dry canning is NOT the same as water bath canning.

As warned about by NM State University, there are a lot of potential problems with dry canning.

  • There’s no evidence that the process actually sterilizes food
  • The process can trap moisture in the jar.
  • Botulism poisoning could occur if moist food is sealed in an oxygen-less container. This is not an issue with foods that have less than 10% moisture content like flour, but condensation trapped in the jar could mean the flour does get very wet.
  • Jars can sometimes EXPLODE

Because of these issues, Mylar bags with oxygen absorbers are the only acceptable method for storing flour long-term.

Frequently Asked Questions About how do you store flour for years

If you have questions that need to be answered about the topic how do you store flour for years, then this section may help you solve it.

How can flour be preserved for ten years?

White flour can be preserved for 10 to 15 years by sealing it in Mylar bags with oxygen absorbers, which completely protect it from light, moisture, and oxygen. Since there is no oxygen present in the packaging, even insect eggs cannot hatch.

Can you store flour for a long time?

White flour may last the longest due to its lower fat content, while whole-wheat and gluten-free varieties spoil sooner. In conclusion, flour has a long shelf life but generally goes bad after 3?8 months. You can extend flour’s shelf life by sealing it properly, refrigerating or freezing it, as well as by properly storing it.

How can flour be kept fresh forever?

One bucket will hold six plastic bags of flour; if you’re storing them for a long time, add five 300cc oxygen absorbers per bucket. Storing bulk flour in bags inside your buckets is not an airtight container, though.

Can flour be vacuum-sealed for extended storage?

Rice and pasta may have the same results — both may last up to six months when conventionally stored, but that number jumps to one to two years when vacuum sealed. Flour and sugar, for example, may last up to six months in the pantry, but storing them with a vacuum sealer increases that range to approximately one to two years.

How can flour be stored?

The best place to store flour is in an airtight storage container in a dry and dark place, like a pantry. You can also store flour in a ceramic or stoneware container to protect it from light exposure, which can cause oxidation and an increase in heat.

Is seven-year-old flour still usable?

Most of the time, using expired flour won’t make you sick. If it doesn’t show any signs of deterioration and has been kept in a cool, dry environment, it should be fine for a few months past the printed date.

How can flour be stored?

If you have the tools to vacuum seal your flour, it can last for up to two years and will stay fresh for up to 10 months when stored in airtight plasticware or a glass mason jar.

Do Mason jars work for flour storage?

You could use glass jars, plastic containers, or even a Ziploc bag to store your flour in this manner, and it will stay fresh for approximately a year.

How should flour that weighs 50 pounds be stored?

“Fifty pounds of flour should fit perfectly in a 13-gallon trash can with a lid,” Mary-Frances Heck, our Senior Food Editor, told me. “I’d line it with a few plastic bags, then slide the flour bag in. Top with a cutout of cardboard to fit snugly against the flour, then lid it.”

How should a 25-pound bag of flour be stored?

The best way to store white flour for the longest shelf life is at room temperature for up to 12 months; if you have a large sack and don’t expect to use it all up within that time, divide it into smaller containers for the pantry and put the remainder in the fridge or freezer.

Which is better for flour storage: glass or plastic?

Most people find it easiest to store flour in the pantry, but a plastic storage container with a tight lid is ideal, but a large Ziploc bag is totally fine, too. The impermeable container will keep out pests as well as moisture.

How should flour be stored to prevent bug infestation?

The easiest way to keep your flour fresh and prevent little bugs from getting in is to transfer your flour to an airtight plastic or glass container. “Bugs love food, especially healthy whole grain foods, and if they can find a way in, they’re going for it!” says Chef Sarah House of Bob’s Red Mill.

Can I keep flour in oxygen-absorbing Mason jars?

The best way to store white flour is in an airtight container with an oxygen absorber (#10 can, Mylar bag, mason jar, or PETE plastic bottle).The oxygen absorber not only increases the shelf life of the flour but also keeps insects from surviving in storage.
