摘要
本研究利用高效液相色谱-质谱联用(HPLC-MS)技术及CIELab法,比较了新橡木桶及使用过一年的旧橡木桶陈酿对赤霞珠干红葡萄酒花色苷含量及颜色变化的影响。结果显示:新橡木桶陈酿的红葡萄酒中单体花色苷、酰化花色苷及总花色苷的含量均低于旧橡木桶,其颜色比旧橡木桶深,红色色调较高,而黄色色调较低,但新旧橡木桶陈酿对葡萄酒花色苷及颜色的影响没有统计学上的显著性差异。研究结果为葡萄酒生产中橡木桶的合理应用提供了参考。
Changes in anthocyanin concentrations and color parameters of the red wines aged for one year in the new oak barrels and the old ones were studied using the technique of high performance liquid chromatography coupled with tandem mass spectrometry （HPLC-MS） and the method of CIELab. The result showed that the wines aged in the new oak barrels had lower concentrations of monomeric, acylated and total anthocyanins, and presented deeper red color, higher red hue and lower yellow hue. But no statistically significant difference of the anthocyanins and coloring was observed between the wines aged in new and old oak barrels. This research provided some reference for preferable application of oak barrels in wine industry.
