利用全二维气质联用技术和吸附搅拌萃取技术对中国名酒剑南春酒体风味质量特色的研究

Analyze Trace Aroma Substances of Chinese Famous Distillery Jian'nanchun by SBSE Absorption Technology and GCxGC/TOFMS Technology

白酒是中国特有的一种蒸馏酒,其独特的生产工艺赋予了它独特的滋味特色,其中包括了数量众多的微量香味成分。随着科技的进步,研究人员对传统固态白酒的风味成分分析越来越深入透彻。而针对白酒这类复杂体系的分离分析需要,多维联用技术已经成为近年来国际上研究的热点。其中全二维气相色谱(GC×GC)及其与飞行时间质谱(TOFMS)联用即是新近发展起来的一种高分辨、高灵敏度的分离鉴定技术。剑南春科技人员创造性地将搅拌吸附萃取(SBSE)和全二维气相色谱/飞行时间质谱联用技术(GC×GC/TOFMS)联合应用,对剑南春等其他中国名酒展开了全面细致的研究,并且在中国名酒剑南春中分析检测出上千种微量成分,远远多于利用其他分析技术所检测到的组分。将全二维气相色谱/飞行时间质谱和SBSE技术联合应用到白酒行业中,将对白酒产品的质量控制、酒体设计、新产品开发等研究项目有重要的指导和促进作用,非常有利于提高白酒的品质和中国白酒的风味研究。

The Chinese distillery is a typical and unique distillery product in China.This typical spirit contains numerous trace fragrant ingredients because if its special operating procedure.As the development of analytical technology,researchers could study the taste and aroma substances in Chinese spirit more and more thoroughly.Comprehensive two-dimensional gas chromatography plus TOFMS(GC×GC/TOFMS) is a newly developed analytical technology which has ultra high resolution and sensitivity.Researchers in Jian'nanchun Corporation creatively used SBSE absorption technology and GC×GC/TOFMS to do comprehensive and delicate research about trace aroma ingredients in Jian'nanchun and other Chinese famous distilleris.We found more than 1000 trace compounds in Chinese famous distillery Jian'nanchun,which are much more than the compounds found by other analytical means. The thoroughly analysis of aroma substances in spirit by using SBSE absorption technology and GC×GC/TOFMS technology will be a great improvement and give important guidance to the quality control of liquor production,the design of spirit body,the development of new products and other researching projects.and it could also be very useful to improve the quality of spirit and the ability of research about the Chinese distillery.
