Melatonin is a bioactive compound that is present in wines because of the metabolism of l-tryptophan by yeasts. Even though the complete pathway of synthesis is not well elucidated, certain related indolic compounds might be involved in it. Consequently, their determination is a matter of interest. On one hand, their formation during fermentation might be related to a specific role for yeasts metabolism,...
Melatonin (N‐acetyl‐5‐methoxytryptamine) is a molecule implicated in multiple biological functions. Its level decreases with age, and the intake of foods rich in melatonin has been considered an exogenous source of this important agent. Orange is a natural source of melatonin. Melatonin synthesis occurs during alcoholic fermentation of grapes, malt and pomegranate. The amino acid tryptophan is the...
