Autoxidation

Autoxidation is a chemical reaction that occurs when certain substances, especially organic compounds, react with oxygen in the air without the need for external energy or heat. This process can lead to the deterioration of materials, such as the rancidity of fats and oils, or the discoloration of fruits. During autoxidation, free radicals are formed, which can further react with other molecules, causing chain reactions that can damage cells and materials. It is a natural process but can be accelerated by factors like light, heat, and the presence of metals, impacting the quality and shelf life of various products.
