The effect of two anti-fungal treatments (metrafenone and boscalid + kresoxim-methyl) on the color and phenolic profile of Tempranillo and Graciano red wines has been studied. To evaluate possible modifications in color and phenolic composition of wines, control and wines elaborated with treated grapes under good agricultural practices were analyzed. Color was assessed by Glories and CIELab parameters. Color changes were observed for treated wines with boscalid + kresoxim-methyl, leading to the production of wines with less color vividness. Phenolic profile was characterized by HPLC analysis. Boscalid + kresoxim-methyl treatment promoted the greatest decrease on the phenolic content in wines.
本研究考察了两种抗真菌处理（甲氧基呋菌酮和唑菌酯+克菌丹）对添普兰尼洛和格雷拉乔红葡萄酒颜色和酚类物质组成的影响。为了评估葡萄酒颜色和酚类物质组成可能发生的变化，分析了采用经过良好农业规范处理的葡萄酿造的控制酒样和处理酒样。通过 Glories 和 CIELab 参数评估颜色。结果表明，唑菌酯+克菌丹处理的葡萄酒颜色发生了变化，导致葡萄酒的颜色鲜艳度降低。采用高效液相色谱法分析了酚类物质组成。唑菌酯+克菌丹处理使葡萄酒中的酚类物质含量下降幅度最大。
