摘要
为了分析不同香型白酒的挥发性成分差异,利用气相色谱-离子迁移谱法(GC-IMS)对馥郁香、浓香、酱香、兼香、小曲清香、大曲清香型六种白酒中挥发性成分进行定性和相对定量分析,并结合指纹图谱、主成分分析(PCA)对样品进行鉴别。结果表明,六种白酒共检出73种挥发性风味物质,包括酯类28种、醇类11种、醛类12种、酮类9种、萜稀类6种以及其他类7种;指纹图谱表明,清香和小曲清香型白酒的特征风味物质有2-乙基呋喃、甲酸乙酯,酱香型白酒是3-羟基-2-丁酮、糠醛、二丙基二硫,馥郁香型白酒为丁酸异丁酯、2-已烯醛、柠檬烯、己酸丁酯;主成分分析结果表明,在风味物质种类和含量上馥郁香型和浓香型、兼香型白酒更接近,小曲清香型白酒和大曲清香型白酒归为一类,酱香型独成一类。
To analyze the volatile components of Baijiu with different flavor types,the volatile components in Fuyu-flavor,strong-flavor(Nongxiangxing),sauce-flavor(Jiangxiangxing),Jian-flavor,Xiaoqu light-flavor Baijiu and Daqu light-flavor Baijiu were qualitatively and quantitatively analyzed by gas chromatography-ion mobility spectroscopy(GC-IMS),fingerprint mapping and principal component analysis(PCA).The results showed that a total of 73 volatile substances were detected in the six types of Baijiu,after removing monomers,dimers and some unknown substances,including 28 esters,11 alcohols,12 aldehydes,9 ketones,6 terpenes and 7 other substances.The fingerprint results showed that the characteristic substances of light-flavor and Xiaoqu light-flavor Baijiu were 2-ethylfuran and ethyl formate.The characteristic substances of sauce-flavor Baijiu were 3-hydroxy-2-butanone,furfural,dipropyl disulfide.The characteristic substances of Fuyu-flavor Baijiu were isobutyl butyrate,2-hexenal,limonene and butyl hexanoate.PCA results showed that in terms of flavor types and contents,Fuyu-flavor Baijiu was similar to strong-flavor and Jian-flavor Baijiu,Xiaoqu light-flavor Baijiu and Daqu light flavor Baijiu were classified into one category,the sauce-flavor Baijiu was classified as one category.
