Oxidation occurs when oil reacts with oxygen in the air, breaking down the fatty acids and forming compounds like aldehydes and ketones. This inherent stability dictates how you should store different oils in your pantry.
The Science Behind Oil Degradation and Rancidity
Proper Storage for Longevity Extending the life of your cooking oil is largely about mitigating the factors that cause oxidation. While pure triglycerides are relatively stable, they are susceptible to two primary chemical processes that lead to spoilage: oxidation and hydrolysis.
Cooking oils are a fundamental component of nearly every kitchen, used for sautéing, frying, baking, and dressing salads. Instead, transfer it to an opaque container or keep it in its original dark glass bottle if provided.
The Chemistry Behind Oil Degradation and Rancidity
You should never store oil in a clear glass bottle on a sunny counter or above the stove. Understanding Oil Chemistry and Rancidity To grasp why oil expires, one must look at its chemical composition.
