荔枝产香内生菌的挥发性成分分析及其在卷烟中的应用研究

Analysis and Study of Volatile Components and Its Cigarette Utilization from Lichee Endophyte

摘要:

对新鲜荔枝内生菌进行分离纯化，共获得5株纯系微生物。通过筛选获得一株代谢产物香气优雅、甜润、生长迅速的菌株。利用GC-MS对其发酵产物进行分析，结果表明该微生物代谢产物的香气成分主要为-苯乙醇，2,3-丁二醇，糠醛及十六酸。利用该菌株发酵制备得到的发酵型烟用香料产品Lizhi-A具有使烟香柔和、细腻、饱满的作用。

Abstract:

Five strains of Endophyte were purified from the endophyte in fresh lichees, One of them was selected as a sample because of its fragrant metabolite and speedy growth. The metabolite which was analyzed by GC-MS showed that the fragrance components were mainly from β-phenylethyl alcohol, 2,3-butanediol, furfural and n-hexadecanoic acid. The product of fermented tobacco flavor Lizhi-A from this kind of the sample strain had ability to make smoke more gentle, smooth and tobacco tasted gently, tenderly and rich.
