How To Store Flour. General Tips And Regulations

Flour may seem to be a very simple product to store. You buy a packet of it in the shop, bring it home, toss to the far shelf, and forget about it until the time you will need it.

But everything is not so simple!

Flour is quite a tricky stuff to keep, and knowing certain rules and tips is a must, otherwise, there is a huge risk or spoiling a foodstuff earlier than needed.

To begin with, it is important to note that the storage of refined flour (e.g. self-rising, all-purpose, pastry, and bread flours) and special flours (for instance, whole grain flour) is slightly different.

  • To store refined flour at home, transfer it to the re-sealable tank after you buy the product. 
  • Never leave it in the original paper packet.
  • Always keep refined flours protected from the moisture, bugs, and air (tanks with the firm lid will help!).
  • Find a dark and cool place to keep the product in. A kitchen cabinet or a pantry will be the best option.

What about the specialty flours? Do whole-grain, quinoa, barley, nut, and other flours need another storage conditions? In fact, they do.

  • For long-term storage, you’d better keep the flour refrigerated since these sorts of flour have a much shorter lifespan compared to their traditional counterparts.
  • For oily flours like nut flour, remove them to the freezing camera in a frost-resistant tank. It will prevent the oils they contain from oxidizing.
  • Always make sure that the storage container is dry!

And of course, check the flour for the signs of spoilage regularly in order not to miss the crucial moment when the product must be thrown away.

Even though this product is basically safe to consume and use even if it is slightly off, and old flour won’t make you badly sick, it is better to ensure that the one you are using is consumable.

How To Tell If Flour Is Bad. Major Symptoms to Note

Naturally, a question occurs about how to define the moment when flour turns bad. Indeed, it has no smell so it will be pretty hard to sense something. Maybe, there is something about its color that can help?

Let’s take a closer look!

The only thing that must be remembered about this issue is that flour can’t become seriously harmful to our health unless some insects or water got into its tank.

So how do we define the spoiled product?

  • If you see big clumps inside the tank, it means that water got inside it
  • Any sort of organic growth also means that the flour was exposed to water or excess humidity
  • Any bugs or insects found inside the product indicate that it is off
  • If the flour smells rancid, discard it without hesitation

In any of these cases, throw the flour instantly! If the bugs were spotted, clean and disinfect the cabinet and the flour tank.

Anyway, if you have any suspense regarding the flour quality, it is better to discard the product rather than taking a risk and consuming it.

And besides, bad flour will not be the same easy in cooking and baking as its fresh counterpart.

So if you notice your cake is not doing well, probably the flour is off.
