En los últimos años, la melatonina ha sido identificada en diversas matrices alimentarias, principalmente de origen vegetal como frutas (uvas, fresas) y verduras (tomates, pimientos). Sin embargo, ha generado un notable interés el hecho de detectar melatonina en alimentos fermentados como el vino o la cerveza. Todo parece indicar que la...

Melatonin (Mel), originally considered a neurohormone, has been detected in beverages and food-fermented products in which yeast metabolism is highly important. This indolamine is synthesized from serotonin, with L-tryptophan being the initial substrate of both. Regarding Mel metabolism, the biosynthetic pathway in mammals consists in four-step...

Background and Aims:Tryptophan is involved in the formation of bioactive compounds, such as melatonin (MEL) and3-indoleacetic acid (3-IAA), by yeast. Melatonin is a neurohormone whose occurrence in wine has been widely reported inrecent years. The occurrence, however, of MEL and other indolic compounds related to tryptophan metabolism by...

Stilbenes are phenolic compounds present in different higher plant families that have shown different biological activities, such as antioxidant properties and antitumoral and anti-atherosclerotic effects, among others. Angiogenesis is a key process involved in both cancer and cardiovascular diseases, the vascular endothelial growth factor...

Hydroxytyrosol is well known for its potent antioxidant activity and anticarcinogenic, antimicrobial, cardioprotective and neuroprotective properties. Main food sources are olive oil (formed from the hydrolysis of oleuropein) and wine. One possible explanation to its origin in wines is the synthesis from tyrosol, which in turn is produced from...

Certain bioactive compounds that derive from tryptophan have been determined in fermented foods, which suggests that the role of yeast is putative in origin. Melatonin is a neurohormone in humans that plays an important role in health. The activity of other compounds, such as 3-indoleacetic acid, has been recently highlighted, and interest in...

Melatonin and serotonin are bioactive compounds present in foods and beverages and related to neuroprotection and anti-angiogenesis, among other activities. They have been described in wines and the role of yeast in their formation is clear. Thus, this study evaluates the content of these bioactives and other related indolic compounds in beer....
