Peroxydation et réaction intra-moléculaire Les huiles d’olive deviennent rance au cours du temps. Le rancissement est une modification chimique des structures moléculaire des huiles végétales. Les mêmes mécanismes chimiques opèrent aussi sur les huiles essentielles. La présence d’oxygène naturellement dissous dans les huiles, initie ces réactions chimiques. Elles s’accélèrent en présence de lumière, d’air, de sauts de température ou de diverses impuretés. Le mécanisme réactionnel de ce « vieillissement » se divise en deux étapes: la peroxydation et les réactions intramoléculaires (ou phase de propagation). La littérature scientifique décrit plusieurs exemples de peroxydation. Voici celui du linalol abondemment présent dans les huiles essentielles. (Exemple: lavande, lavandin, thym à linalol, bois de rose, sauge sclarée, etc). Dans ce shéma, le linalol subit en premier une peroxydation. Elle produit un nouveau composé: le 7-dydroperoxy-3,7-dimethyl-octa-1,5-diene-3-ol.
