What can you do with expired flour?

Expired flour doesn’t carry any risk if it is stored correctly and it can therefore be consumed several years after the expiration date. However, always check that no pests have come to nest in your package. Store it preferably in an airtight container. 

If flour is stored poorly, it may show signs of fermentation, become rancid, change color, or host unwanted pests (food moths). Some flours, rich in Omega-3, also tend to oxidize faster and therefore need to be consumed more quickly. If you have any doubts about the quality of your flour, don’t throw it away, but recycle it! Because everything can be recovered (or almost), and below we offer you some anti-waste ideas for reusing expired flour.

Reusing and recycling expired flour is also another step towards Zero-waste. It is a fact that more and more of us are being made aware of the need to stop producing so much waste.

Can you use expired flour for baking?

You can use expired flour. In baking mixes and flours, they can be safely consumed up to 30 days after the expiration date on the packaging. However, all-purpose flour (wheat) can last six to eight months after the date printed on the package; Whereas whole wheat flour is best consumed for four to six months afterward.

Corn flour lasts from nine to 12 months, rice flour lasts from six to eight months, potato flour lasts the same.

But how is it possible to recognize that flour is not safe to use? You just have to sniff it, meaning if it smells musty, then it’s not helpful. Too long after its expiration date, the flour will begin to give off this aroma.

Some insects will invade the flour in the worst case because moisture can attract them, but it is very rare.
