摘要
利用自动质谱图解卷积和鉴定系统并结合标样和保留指数定性在蛇龙珠和卡曼娜葡萄酒中鉴定出116种挥发性风味物质,并根据定量结果和各物质的感官阈值对每种物质的香气活性值(OAV)进行计算,寻找出2种葡萄酒中的主要呈香物质并根据OAV值对这2种葡萄酒的香气轮廓进行了模拟计算。研究发现我国河西走廊的蛇龙珠葡萄酒和智利莫莱山谷的卡曼娜葡萄酒总体香气轮廓较为相似,蛇龙珠中的C6醇类、脂肪酸乙酯、脂肪酸、醛、萜烯、降异戊二烯和内酯类物质含量较高,而卡曼娜中的乙酸酯、高级醇和酮类物质含量较高。蛇龙珠的花香、焦糖味和橡木味相对较强,β-大马士酮、左旋-2,3-丁二醇、苯乙醛和己酸乙酯、己酸、异丁醇、异戊醇7种物质是2种葡萄酒共同的主要呈香物质。
A total of 116 volatile compounds Carmenere red wines from China and Chile were identified by automatic mass spectral deconvolution and identification system combining with standard sample and retention index qualitative method. Odor activity values （OAV） were calculated according to the quantitative result and sensory threshold. Two main aroma substances were found and the aroma profile was calculated based on OAV. Results showed that the aroma profile of Chinese Carmenere （also called SheLongZhu） in Hexi corridor was similar to Chilean Cannenere. Chinese Carmenere contained more C6 alcohols, ethyl esters, fatty acids, aldehydes, terpenes, norisoprenoids and lactones, while Chilean Carmenere contained more acetic acid ester, higher alcohols and ketones. The flower flavor, caramel flavor and oak flavor in Chinese Carmenere were relatively stronger than Chilean Carmenere. The common main aroma substances in two Carmenere were beta-damascenone, L-2,3-butanediol, phenylacetaldehyde, ethyl caproate, hexanoic acid, isobutyl alcohol and isoamyl alcohol.
