Some biogenic amines (BAs) are used as quality markers in grape-derived products. The prolife of 9 BAs was determined in juices and wines elaborated from hybrid grapes. Low levels of histamine, tyramine and cadaverine were found. Juices elaborated from ‘BRS Rúbea’ showed the highest tyramine levels (1.56 mg/L), while no histamine was found in wines elaborated from ‘Seleção 34’ and its higher content was detected in ‘BRS Carmem’ (3.55 mg/L). Juices elaborated from ‘BRS Violeta’ showed elevated content (472.88 mg/L) of total phenolic compounds (TPC) and mono-hydrated serotonin (6.20 mg/L), and wines elaborated from ‘Violeta’ presented a high serotonin mono-hydrate content (23.63 mg/L) and high antioxidant activity with FRAP test (77.24 mmol FeSO 4 /L). Juices elaborated from hybrid grapes ‘BRS Violeta’ and wines from ‘BRS Violeta’, ‘Seleção 34’ and ‘Seleção 13’ had high levels of bioactive compounds, emphasizing the great potential of these cultivars for winemaking.

生物胺和巴西杂交葡萄汁和葡萄酒的抗氧化能力

一些生物胺 (BA) 被用作葡萄衍生产品的质量标志。在由杂交葡萄制成的果汁和葡萄酒中测定了 9 种 BA 的增殖。发现低水平的组胺、酪胺和尸胺。用'BRS Rubea' 酿造的果汁显示出最高的酪胺水平（1.56 毫克/升），而在用'Seleção 34' 酿造的葡萄酒中没有发现组胺，而在'BRS Carmem' 中检测到其含量更高（3.55 毫克/升）。用“BRS Violeta”酿造的果汁显示总酚类化合物 (TPC) 和一水合血清素 (6.20 mg/L) 的含量升高（472.88 毫克/升），用“紫罗兰”酿造的葡萄酒的一水合血清素含量较高(23.63 mg/L) 和 FRAP 测试的高抗氧化活性 (77.24 mmol FeSO 4 /L)。由混合葡萄“BRS Violeta”和来自“BRS Violeta”的葡萄酒制成的果汁，
