Caracterização físico-química e aminas bioativas em vinhos da cv. Syrah I: efeito do ciclo de produção

Abstract: Na maioria das regiões vitícolas brasileiras o período de colheita das uvas coincide com a época de maior intensidade pluviométrica, condição que afeta negativamente a qualidade dos vinhos obtidos, em especial a dos vinhos tintos. A ocorrência sistemática de dias chuvosos ou com alta nebulosidade, aliada às temperaturas ambientais elevadas prejudica não só a maturação das uvas, mas também a sua sanidade devido à ocorrência de inúmeras podridões dos cachos. Nessas condições, os viticultores são levados a anteci… Show more

“…Wine composition of Syrah grapes from Pirapora presented higher alcohol content and anthocyanins concentration but lower color intensity and color shade when compared to Syrah wine from grapes harvested in the winter at Três Corações vineyards, in the southern region of Minas Gerais (MOTA et al, 2009). Total phenolic index and color intensity were significantly higher than the average 31.16 and 7.0, respectively, observed by Santos and Kaye (2009) in Syrah wine in California.…”

“…Putrescine is a catabolic product of the ornithine or arginine pathways, which can be converted to spermidine and form spermine, these three are interconversible molecules (Russo et al, 2010). Mota, Amorim, Fávero, Gloria, and Regina (2009) studied wines and reported high putrescine levels in the winter in two harvests. For the authors, one of the reasons for putrescine accumulation in the grape occurred because the grapes were cultivated during the dry season and underwent water stress or because there was potassium deficiency, evidencing that this amine may be related those factors other than the hygienic conditions.…”

“…Spermidine was detected in all samples analyzed, whereas spermine was detected only in Control/Apis [T120], Banana/Apis [T0] and [T120], Control/Melipona [T120], Passionflower/Melipona [T120]. Spermidine and spermine are associated with plant morphogenesis, acting as growth regulators and as response to environmental conditions (Mota et al, 2009).…”

“…Vitis vinifera produzidos no Vale do São Francisco, os quais variaram entre 1992 e 2645 mg/L e mais próximos aos encontrados por Mota et al (2009) Os resultados encontrados para a intensidade de cor obtiveram grande heterogeneidade, o que pode atestar a variabilidade das uvas utilizadas para os vinhos, uma vez que esse parâmetro reflete a característica de cada variedade (Ribéreau-Gayon et al, 2002). encontraram valores entre 7,78 a 11 para vinhos italianos envelhecidos em garrafas.…”
