Tips To Store almond flour

Spoiled food items often lead to frustration. And this frustration can be prevented if you store your almond flour properly. Proper storage prolongs its shelf life and now I am sharing some tips to store almond flour:- 

1. Refrigerate

If you have a large stock of almond flour then you should keep it in your fridge. It will prevent it from spoilage because the fridge provides a low temperature that is not suitable for the growth of mold and fungi. 

2. Cool place in the pantry

If you don’t have a fridge or have limited stock then you can also store it in a cool place in your pantry or even in your kitchen cabinet. If you are storing your almond flour outside the fridge then make sure that it is not near any heat source like a gas stove or dishwasher.

3. Seal it tightly after use

Once you open the almond flour bag then after using it you should seal it tightly for the next use. This will prevent the almond flour from being in contact with air and moisture as we know that air and moisture promote oxidation and it also increases the chances of molds, so it is better to avoid that. 

4. Away from heat sources

Heat sources favor the growth of molds or fungi that can further spoil your almond flour, reducing its shelf life. So try to store it away from heat sources. 

5. Freeze it 

If you have bought so many almond flour bags then freezing them is the best option. It will increase their shelf life and they won’t get spoiled soon.  

What happens if you use Expired almond flour?

If an opened bag is stored in a pantry, it is good to use it before its best-by date and if it is unopened then you can use it for 2-4 months. If you are using almond flour that has gone out of the best-by date and was stored properly then it will not cause any damage and it won’t make you sick. But, if your almond flour was attacked by molds or fungi then it will make you sick.

Molds release enzymes known as mycotoxins. These enzymes can make you sick by irritating your digestive tract and food poisoning. If you suffer from any of these then you should go to hospital as soon as possible. ( Reference 1)
