中文摘要:

      目的 基于非靶向代谢组学技术, 解析五粮液系列白酒的挥发性组分特征及差异。方法 利用非靶向代谢组学技术研究五粮液、五粮醇、五粮春、五粮特曲和五粮头曲5个系列白酒中挥发性组分特征及差异。结果 5个系列白酒中共检出900种化合物, 其中胺类26种、醇类86种、芳烃类51种、酚类18种、含氮化合物类11种、含硫化合物类11种、卤代烃类3种、醚类4种、醛类47种、酸类28种、萜类143种、烃类78种、酮类79种、杂环化合物139种、酯类172种、其他类4种。不同五粮液白酒检出化合物的数量和组成存在差别, 五粮液中差异显著化合物数目显著高于五粮醇、五粮春、五粮特曲和五粮头曲。结论 不同五粮液系列白酒中组成和含量的差异是反映白酒品质的重要因素, 非靶向代谢组学技术在白酒特征成分的分析鉴定中具有良好的应用性, 为科学区分五粮液系列白酒提供可靠的数据支持。

英文摘要:

      Objective To analyze the characteristics and differences of volatile components in Wuliangye liquor based on non targeted metabonomics technology. Methods The characteristics and differences of volatile components of 5 series of liquor including Wuliangye, Wuliangye alcohol, Wuliangchun, Wuliangtequ and Wuliangtouqu liquor was analyzed by non targeted metabonomics technology. Results A total of 900 kinds of compounds were detected in 5 series of liquor, including 26 kinds of amines, 86 kinds of alcohols, 51 kinds of aromatics, 18 kinds of phenols, 11 kinds of nitrogenous compounds, 11 kinds of sulfur compounds, 3 kinds of halogenated hydrocarbons, 4 kinds of ethers, 47 kinds of aldehydes, 28 kinds of acids, 143 kinds of terpenes, 78 kinds of hydrocarbons, 79 kinds of ketones, 139 kinds of heterocyclic compounds, 172 kinds of esters, and 4 kinds of others. The number and composition of compounds detected in different Wuliangye liquor were different. The number of compounds with significant differences in Wuliangye was significantly higher than that in Wuliangye alcohol, Wuliangchun, Wuliangtequ and Wuliangtouqu. Conclusion The difference of composition and content in different Wuliangye series liquor is an important factor reflecting the quality of liquor. Non targeted metabonomics technology has good application in the analysis and identification of liquor characteristic components, providing reliable data support for scientific differentiation of Wuliangye series liquor.
