Previously, we reported that alcoholic fermentation enhanced flavanones and carotenoids content of orange juice. The aim of this work was to evaluate the influence of pasteurization on the qualitative and quantitative profile of bioactive compounds and the antioxidant capacity of fermented orange juice. Ascorbic acid (203 mg/L), total flavanones (6...

Metabolic syndrome (MetS) refers to a group of disorders that includes insulin resistance, central obesity, arterial hypertension and hyperlipidaemia. Regular consumption of bioactive compounds has consistently been associated with a reduced risk of these disorders. The aim of this study was to determine if an orange beverage with high concentratio...

The fermentation of fruit produces significant changes in their nutritional composition. An orange beverage has been obtained from the controlled alcoholic fermentation and thermal pasteurization of orange juice. A study was performed to determine the influence of both processes on its amino acid profile. UHPLC-QqQ-MS/MS was used for the first time...

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...

It is accepted that the intake of fruits and vegetables, which contains antioxidant compounds such as flavonoids and carotenoids, intensify the protection against many diseases related to oxidative stress. Moreover, moderate alcohol consumption confers cardiovascular protection. Both effects could join in a novel drink created by alcoholic fermenta...

The intake of bioactive compounds and moderate alcohol decreases the risk of cardiovascular diseases. These effects could be joined in a beverage created by a controlled alcoholic fermentation of orange juice. The influence of controlled alcoholic fermentation on the bioactive compound profile of orange juice has not been previously evaluated, and...

The capacity of tumour necrosis factor-related apoptosis-inducing ligand (TRAIL) to trigger apoptosis preferentially in cancer cells, although sparing normal cells, has motivated clinical development of TRAIL receptor agonists as anti-cancer therapeutics. The molecular mechanisms responsible for the differential TRAIL sensitivity of normal and canc...

Statins are inhibitors of the mevalonate synthesis pathway that induce apoptosis in tumor cells although the apoptotic mechanism activated by statins remains to be elucidated. We have examined the role of the mitochondria-operated pathway of apoptosis in the cell death induced by statins in breast tumor cells and its regulation by protein prenylati...
