Oxidation
Natural phenols are reactive species toward oxidation, notably the complex mixture of phenolics, found in food for example, can undergo autoxidation during the ageing process. Simple natural phenols can lead to the formation of B type proanthocyanidins in wines or in model solutions. This is correlated to the non-enzymatic browning color change characteristic of this process. This phenomenon can be observed in foods like carrot purees.
