摘要
该研究利用非靶向代谢组学方法研究五粮液、五粮醇、五粮春、五粮特曲和五粮头曲5个系列白酒的非挥发性组分,并解析其组分特征及差异。结果表明,通过液相色谱-质谱联用法,5个系列白酒共检出317种非挥发性化合物,其中五粮液白酒中检出296种,五粮醇白酒中检出275种,五粮春白酒中检出293种,五粮特曲白酒中检出269种,五粮头曲白酒中检出282种,不同五粮液白酒检出非挥发性化合物的数量和组成存在差别,五粮液白酒含有的化合物类别最丰富,其次是五粮春白酒。主成分分析(PCA)结果表明,五粮液和五粮春两款白酒在第一主成分上明显区别于五粮醇、五粮特曲和五粮头曲三款白酒。由聚类分析(CA)可知,五粮液和五粮春聚为一类,五粮醇、五粮特曲和五粮头曲聚为一类。不同五粮液白酒中非挥发性风味化合物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。
The non-volatile components of five series of Baijiu(Wuliangye,Wuliang Chun(mellow),Wuliang Chun(spring),Wuliangtequ and Wu-liangtouqu)were studied by non-targeted metabonomics,and their component characteristics and differences were analyzed.The results showed that 317 kinds of non-volatile compounds were detected in five series of Bajiu by liquid chromatography-mass spectrometry,including 296 kinds in Wu-liangye,275 kinds in Wuliang Chun(mellow),293 kinds in Wuliang Chun(spring),269 kinds in Wuliangtequ and 282 kinds in Wuliangtouqu.The number and composition of non-volatile compounds were different in the series of Wuliangye Baijiu.Wuliangye contains the most abundant non-volatile compounds,followed by Wuliangchun.The results of principal component analysis(PCA)results showed that Wuliangye and Wuliang Chun(spring)were significantly different from Wuliang Chun(mellow),Wuliangtequ and Wuliangtouqu in the first principal component.According to cluster analysis(CA),Wuliangye and Wuliang Chun(spring)were grouped together,while Wuliang Chun(mellow),Wuliangtequ,and Wuliangtouqu were grouped together.The difference of composition and contents of non-volatile component in different Wuliangye Baju was an important factor reflecting the quality of Baijiu,non-targeted metabonomics technology had good application in the analysis and identification of Bajiu characteristic components.
