Shelf life of flour by type

Regular all-purpose flour it takes a very long time – a year at room temperature and two years in the refrigerator or freezer. The same goes for other white flours – such as self-rising flour, white bread flour and white cake flour.

On the other hand, wholemeal flour has a duration of shorter shelf life. The reason: Wholemeal flour contains cereal bran and germ, which are high in fiber and other nutrients, but spoil more quickly. As a result, wholemeal flour is preserved up to three months at room temperature and up to one year in the refrigerator or freezer. The same goes for oat flour and other wholemeal flours.

How do you know if the flour has gone bad?

Each bag of flour has a printed on it validity or expiration date. If you transfer the flour to an airtight container before storing it, label the container with the expiration date before throwing away the original packaging of the flour.

There is a simple way to tell if flour has expired: It just smells!

“Flour it should not have a smell, or at most a minimal nutty or sweet smell,” say nutritionists. “When the flour spoiled, it has a more sour smell or more like clay’. Although the smell is usually quite subtle, you should be able to detect it.

What period of time is the flour with the expiry date still good for consumption?:

  • White flour: 6-8 months
  • Rice flour: 6-8 months
  • Maize flour: 12 months
  • Potato flour: 8 months
  • Wholemeal flour: 4-6 months
  • Flour with raising agent: 6 months

Is it dangerous to eat expired flour?

Consumption of expired flour, in general, has no significant consequences. Most of the time, nothing happens except that the products are baked they don’t taste good.

However, there is a small chance that eating expired flour make you sick. If rancid flour contains large amounts of mycotoxins, you can get sick. Mycotoxins are toxic compounds produced by certain types of mold.

But flour with so much mold has a rather strong sour smellwhich you will most likely perceive as soon as you open the bag or container.
