This will kill any harmful pests and will prevent rancidity.
How Long Can Flour Be Stored in the Fridge?

Is It Better to Store Flour in the Fridge or Freezer?
It usually depends on personal convenience, but a freezer is better if you want to store flour for a long time.
The fridge has an average temperature of 1.6°C, while the temperature in the freezer can be as low as -18°C. The microbes can’t grow at such low temperatures.
The humidity levels are also low in the freezer compared to the fridge, which can keep the flour fresh for a long time.
Best Way to Store Flour Long Term?
Storing flour long-term is all about finding the right balance of temperature and moisture.
If it’s too warm, the flour will go bad; if it’s too dry, it will become brittle and difficult to use.
The best way to store flour is in a cool, dry place like a pantry or cupboard.
If you’re worried about pests getting into your flour, you can store it in an airtight container.
You can also freeze flour for longer-term storage. Just be sure to thaw it completely before using it.
How Can You Tell If Flour is Bad?
You can tell if the flour is bad by smelling it.
The flour will smell like yeast or baking soda if it is bad. It might also be caked together or have bugs in it.
If you’re unsure whether the flour is bad, try tasting a little bit of it. Bad flour will taste bitter or soapy. If it’s really old, it might even taste moldy.
In the rotten flour, you can also find discoloration and clumps of fungi or moisture.
Is It Safe to Store Flour in a Plastic Container?
Yes, you can store flour in a plastic container. But don’t forget to make it airtight.
If your flour smells musty or sour, it has probably gone bad, and you should discard it.
To prevent your flour from going bad, store it in a cool, dry place.
How to Store Flour to Prevent Bugs?
To prevent the flour from bugs, store it in plastic and metal containers with an airtight seal.
You can also use a food-grade bucket with a lid or a resealable bag.
Moreover, if you have just bought the flour, place it in the freezer for a few days.
This will kill any eggs and will restrict the growth of bugs.
Does Flour Go Bad?
Yes, flour can go bad. It depends on how it’s stored and the type of flour.
For example, whole wheat flour will go bad quicker than all-purpose white flour.
Regular flour lasts for three to eight months. Pay attention to the expiry date to determine how long the flour will last.

Let’s wrap up the things. We just discovered that flour could go bad if it is not stored properly.
Moreover, it can also rot due to bugs and moisture in the environment.
