| Resumo: | Grape juices have been valued due to their potential health benefits, which have demanded increased grape productivity and quality. Five grape cultivars grown in Brazil, Isabel Precoce, Carmem, Violeta, Concord and Bordo were evaluated in 2013 and 2014 seasons for bioactive components and also for juice processing quality traits. Production cycle was the longest for Carmem but lower and similar for Violeta, Isabel, Bordo and Concord. Isabel showed higher productivity (5.4 kg∙plant-1) but lowest soluble solids content (16.9 °Brix), anthocyanins (26.7 mg∙100 g-1) and total phenolics (110.7 mg∙100 g-1). The highest anthocyanins contents were observed in Violeta (189.9 mg∙100 g-1) and Bordo (133.8 mg∙100 g-1). These cultivars were also rich in phenolics (356.1 and 239.5 mg∙100 g-1, respectively). The highest anthocyanin and total phenolics concentrations were found in Violeta juice (2.68 and 6.33 g∙L-1) followed by Bordo (1.44 and 2.86 g∙L-1). Isabel juice had the lowest content, 0.14 and 1.29 g∙L-1, respectively. Biogenic amines were found at low concentrations only in the juices. Putrescine and spermidine were the major amines detected in juices. Phenylethylamine was detected only in Bordo juice from 2013 season and tryptamine was detected only in 2014 season. Blends were preferred over varietal juices except for Carmem. |
