What is auto oxidation?

Auto-oxidation is a spontaneous chemical process in which a substance reacts with oxygen, leading to the degradation or deterioration of the material. This process is commonly seen in organic compounds, such as fats and oils, resulting in rancidity. Auto-oxidation involves the formation of free radicals, which propagate further reactions, often leading to undesirable changes in color, flavor, and nutritional quality. Factors such as heat, light, and the presence of catalysts can accelerate auto-oxidation.
