This transformation is not merely a surface stain but a permanent alteration involving new substances, energy changes, and a breakdown of complex molecules into simpler ones. These intermediate compounds are highly reactive and quickly polymerize, linking together to form melanins, the same brown pigments responsible for skin color in humans and the color of coffee.

This process also involves the release of energy, albeit in small amounts, which is characteristic of many oxidation reactions. From Phenols to Quinones Quinones are the key players in this transformation.
Distinguishing Chemical from Physical Change To understand why browning is chemical, it is helpful to contrast it with a physical change. The production of heat or light is not always necessary to identify a chemical change; the creation of a new substance is the definitive marker.
