Rancid flour contains certain harmful compounds produced during fat oxidation. However, consuming rancid flour in small amounts is unlikely to make you sick. If you consume moldy flour, you may experience symptoms of food poisoning like vomiting, diarrhea, fever and stomach pain, etc. Typically, most flour easily lasts months at room temperature.
When stored correctly, these flours last long past their expiry. Different factors like the type of flour, its ingredients, and storage methods impact the shelf-life of the flour. The source ingredients wheat or arrowroot and the processing method greatly affect the shelf-life of the flour. Whole wheat flour has a shorter shelf-life as compared to white all-purpose flour.
White all-purpose flour is extensively processed during which oil-rich bran and germ are removed from the grain leaving behind a starchy endosperm. Whole wheat flour has the oil-rich bran and germ intact, hence, more susceptible to spoilage.
This is because fats oxidize when exposed to light, moisture, or air. Gluten-free flours like almond and coconut flour have a significant amount of fat, thus, a shorter shelf-life.
Gluten-free all-purpose flour which is made by mixing multiple nuts or root-based flours also has a shorter shelf-life due to increased moisture levels. The rule of thumb is to store the flour somewhere dark, dry and cool. Flour has been labeled shelf-stable by the USDA, which means, It can be safely kept at room temperature. Moreover, refrigerating and freezing have resulted in a prolonged shelf-life of flours.
For example,e all-purpose flour has a shelf-life of months at room temperature but It can last 1 year or 2 years If refrigerated or frozen, respectively. The best-by dates printed on the flour packages are not indicators of safety but quality.
While teaching one of my university classes, I used some whole-grain barley flour which I thought was fresh to make scones. I noticed a strange odour while they were baking, but it was only when I sampled my handiwork that I recognized the unmistakable, bitter, cardboard-like taste of rancidity. Without revealing the problem to my students, I asked what they thought of my scones. Sure enough, some grimaced, but others simply brushed off the funky flavour, describing it as being the normal taste of whole-grain food.
With your nose. Rancid foods have the same look and texture as when they were purchased, but their smell and taste have changed. The odour is akin to wet cardboard, oil paint, wood varnish or play dough.
If you use it for cooking, it will lend a bitter taste and unpleasant odour to your dish. Containers also protect against flour-loving insects. Oxygen in the air attacks fat molecules and causes a series of chemical reactions that lead to the formation of new—and decidedly smelly—molecules. These reactions occur even more quickly in the presence of light and heat. Foods that contain polyunsaturated fats are particularly susceptible:. NUTS: When in doubt, go for whole nuts, because they oxidize much more slowly than chopped nuts.
