St Ives Community Foodshare group have been given a large amount of expired flour so have researched what we can do with it rather than throwing it all into landfill.
What can you do with expired flour?
Expired flour doesn’t carry any risk if it is stored correctly and it can sometimes be used years after the expiration date. However, always check the smell and colour and that no insects have come to nest in your package. Store it preferably in an airtight container in a cool, dry, dark place. If you have any doubts about the quality of your flour, don’t throw it away, but recycle it! Below are 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?
If you store all-purpose and other refined flours in a cool, dry place protected from sunlight, refined flour can keep up to one year in the pantry under these ideal conditions, whole wheat flour is best consumed for four to six months afterward. For longer storage, or in a warmer climate, stash the flour in the freezer, where it can last for up to two years. 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 edible. Too long after its expiration date, the flour will begin to give off this musty aroma. Also watch out that insects haven’t invaded the flour. If it smells good, you can still use it. If the color has changed, it means that the product has been affected.
