摘要
为探索不同发酵期对不同糟层浓香型基酒风味成分的影响,采用高效液相色谱法、气相色谱法-氢火焰离子化检测器和顶空固相微萃取结合气相色谱-质谱联用法对不同发酵期、上中下3层糟醅所产基酒中的风味物质进行解析。结果表明,乙酸、丁酸、己酸、庚酸乙酯、丁酸乙酯、己酸乙酯、戊酸乙酯、己酸丁酯、己酸异戊酯、苯乙酸乙酯、己酸己酯、己酸丁酯和乙酸苯乙酯的含量,随着发酵时间的延长呈增加趋势;乳酸、乙醛、葵酸乙酯、异戊酸乙酯、月桂酸乙酯、苯乙醛、乙缩醛、正丁醇、异戊醛、乙酸乙酯、乳酸乙酯、3-苯丙酸乙酯、壬醛、棕榈酸乙酯和萘这15种风味物质在各层的含量随发酵时间的延长出现下降趋势。该实验通过对不同发酵期浓香型基酒在不同糟层的风味成分对比分析,对浓香型白酒生产、勾调、提升成品酒品质具有一定的指导意义。
To explore the influence of different fermentation cycles on the flavor components of Nongxiangxing crude Baijiu with different layers,high-performance liquid chromatography,gas chromatography-hydrogen flame ionization detector,and headspace solid-phase microextraction combined with gas chromatography-mass spectrometry were used to analyze the flavor substances in the crude Baijiu produced in different fermentation cycles,upper,middle,and lower layers of mash.The results showed that the contents of acetic acid,butyric acid,hexanoic acid,ethyl heptanate,ethyl butyrate,ethyl hexanoate,ethyl valerate,butyl hexanoate,isoamyl hexanoate,ethyl phenylacetate,hexyl hexanoate,butyl hexanoate,and ethyl phenylacetate in each layer gradually increased with the extension of fermentation time;Lactic acid,acetaldehyde,ethyl sunflower acid,ethyl isovalerate,ethyl laurate,phenylacetaldehyde,acetaldehyde,n-butanol,isovaleraldehyde,ethyl acetate,ethyl lactate,ethyl 3-phenylpropionate,nonanal,ethyl palmitate,and naphthalene,these 15 flavor substances,showed a downward trend in each layer with the extension of fermentation time.Through the comparative analysis of flavor components of Nongxiangxing crude Baijiu at different fermentation cycles in different lees,this experiment has a certain guiding significance for the production,blending,and upgrading of Nongxiangxing Baijiu.
