全二维气相色谱技术在酒类挥发性化学成分检测中的应用

酒的风味是评价酒质量品质的重要指标，其中的挥发性化学成分是影响风味的关键因素。在酒类挥发性化学成分检测中，与 常用的一维气相色谱相比，全二维气相色谱技术极大地提高了色谱的分离能力和分析速度，具有广泛用途。 该文综述了全二维气相 色谱在中国白酒、葡萄酒、啤酒等不同酒类挥发性物质检测中的应用，为解析不同酒的风味特征提供物质基础和方法参考。

Application of comprehensive two-dimensional gas chromatography in the analysis of flavor chemical components for alcoholic drink

The flavor of alcoholic drink is an important indicator for evaluating the quality. The volatile chemical components are the key factors af- fecting the flavor. Compared with conventional one-dimensional gas chromatography (1D-GC), comprehensive two-dimensional gas chromatography (GC×GC) can realize better separation and analysis speed, and had a wide range of uses in the detection of volatile chemical constituents of alcoholic drink. The application of GC×GC in the determination of flavor components in Baijiu (Chinese liquor), wine and beer, etc. was reviewed, which pro- vided material basis and method reference for analyzing the flavor characteristics of alcoholic drink.
