While the flour itself remains stable, its added baking powder gradually loses potency — just like the can of baking powder in your cupboard does. Yes, you can bake with self-rising flour after its best-by date; but your baked goods may not rise as well.
What happens if you use expired flour?
When flour goes rancid, its molecular structure changes — which may produce harmful compounds ( 10 ). However, no recent studies have revealed any detrimental effects of eating rancid flour. Although cooked foods made with it may taste unpleasant, they’re unlikely to harm your health if eaten in small amounts.
How do you know when flour goes bad?
The best way to determine whether your flour is safe is to smell it. While fresh flour has a neutral odor, bad flour smells off — it can be stale, musty, or almost sour. It may also look discolored. Additionally, if your flour has come into contact with water or moisture, large clumps of mold may appear.
Can you use flour 2 years out of date?
Long story short, yes. The first thing to know is that it will remain good long past its “best by” or “better if used by” date that can be found on the original container. Regular flour tends to last 6-8 months past its printed date, while whole wheat flour is typically only best for an extra 4-6 months.
How do you store flour for years?
You can leave your flour in its original bag, but for long-term storage, it’s best to move it to an air-tight container that can protect against smells (flour will absorb odors) and liquids from the freezer walls.
How long will flour last vacuum sealed?
Flour and sugar, for example, may last up to six months in the pantry, but storing them with a vacuum sealer increases that range to about one to two years. Rice and pasta may have the same results — both may last up to six months when conventionally stored, but that number jumps to one to two years when vacuum sealed.
Can you use expired baking powder?
The baking powder should dissolve immediately and the dry powder is no longer visible. This baking powder is still good and you can use it in your recipes. If the baking powder is expired or stale, the mixture will just have a few bubbles, minimal fizzing and the powder will just float on top of the water.
