摘要
保健酒是以白酒或其他酒类为基酒,佐以中药材,对人体具有保健功效的酒饮料。中国劲酒是保健酒的代表产品之一,通常以清香型小曲酒为基酒,加入淮山药、仙茅、当归、肉苁蓉、枸杞子、黄芪、淫羊藿等药材经过现代提取与分离技术调配制成。采用液-液萃取结合全二维气相色谱-飞行时间质谱联用仪(comprehensive two-dimensional gas chromatography-time-of-flight mass spectrometry,GC×GC-TOF MS)对2种中国劲酒基酒的挥发性成分进行分析,测定其化合物的种类和含量。结果表明:2种中国劲酒基酒中初步定性出挥发性化合物175种,标准品定性化合物40种,其中醇类化合物41种、酯类化合物53种、醛酮类化合物24种、缩醛类化合物2种、酸类化合物24种、呋喃类化合物8种、酚类化合物3种、内酯类化合物8种、含氮化合物8种、含硫化合物1种和酸酐类化合物2种;含氮和含硫化合物在中国劲酒中为首次发现。液-液萃取结合GC×GC-TOF MS技术的分析方法可快速、准确分析鉴定出中国劲酒基酒中挥发性成分,结果旨在为中国劲酒的重要风味物质研究提供参考。
Health-care liquor is a kind of alcoholic beverage with health properties,which is based on Baijiu or other alcoholic drinks,and supplemented with traditional Chinese medicines.Chinese Jingjiu is one of the representative products of health-care liquor,which is usually made based on light-aroma flavor Xiaoqu Baijiu and supplying with dioscoreae rhizoma,curculiginis rhizoma,angelicae sinensis radix,cistanches herba,lycii fructus,astragali radix,epimedii folium and other medicinal materials through modern extraction and separation technology.In this study,the kinds and contents of the volatile compounds of two base distillate of Chinese Jingjiu were qualitatively analyzed by liquid-liquid extraction combined with comprehensive two-dimensional gas chromatography-time-of-flight mass spectrometry(GC×GC-TOF MS).The results indicated that a total of 175 volatile compounds were identified in two base distillate of Chines Jingjiu,and 40 compounds were identified by standard compounds,including 41 alcohols,53 esters,25 aldehydes and ketones,2 acetals,24 acids,8 furans,3 phenolic compounds,8 lactones,8 nitrogen-containing compounds,1 sulfur-containing compound and 2 acid anhydride compounds.Notably,nitrogen-containing and sulfur-containing compounds were firstly identified in Chinese Jingjiu.In conclusion,the combination of liquid-liquid extraction and GC×GC-TOF MS can rapidly and accurately characterize the volatile compounds in base distillate of Chinese Jingjiu.The results could provide reference for the study of important aroma compounds of Chinses Jingjiu.
