摘　　要：建立测定糯米酒中主要杂醇油异丁醇、异戊醇、β-苯乙醇含量的气相色谱法（GC）.糯米酒预处理后,经毛细管色谱柱分离,采用峰面积外标法定量测定糯米酒中的主要杂醇油含量.方法保留时间的RSD值为0.181%-0.699%,峰面积的RSD值为3.37%-4.36%,方法回收率为90.7%-98.5%.本方法具有准确度高、重现性好且分析时间短的优点.In this paper, the determination method was studied to determine the wine by gas chromatography. After pre-treatment, the fusel oil in glutinous rice content of fusel oil in glutinous rice wine was separated by capillary gas chromatography column, and determined with the peak area external standard method. The results show that the RSD value for retention time is 0.181%-0.699%, the RSD value for area is 3.37%-4.36% and the recovery rate of the method is 90.7%-98.5%. It shows that the degree of precision and veracity of the method is higher, analysis time is short.
