摘    要:建立一种测定苹果汁中芳香成分的气相色谱方法。该法采用毛细管柱(SE-54 50m×0.32mm×0.25μm)测定,采用正戊烷提取,在Likens-Nickerson装置中萃取的方法处理样品。方法的线性范围为0.06-1.0μg/L,相关系数r在0.99以上,相对标准偏差均小于10%,加标回收率在90%以上,方法最低检出限0.06μg/L(S/N=3),结果表明,该法在相同的线性浓度范围有很好的线性关系,分离良好。

关 键 词:芳香成分  苹果汁  气相色谱  分析

Abstract:The method of gas chromatography for the determination of aromas in apple juice was established. The method for the determination of aromas with a (50 m×0.32 mm×0.25 μm)SE-54 quartz capillary column was established. The apple juice were extracted with n-pentane. It was purified by Likens-Nickorson. The liner range was between 0.06 ~ 1.0 μg/L ; correlation coefficient was above 0.99; the relative standard deviations(RSD) was below 10 %; the labeled recovery rates were above 90 %; the limit of determination(LOD) was 0.06 μg/L(S/N=3). The results showed that the method had higher linearity in the examined concentration range with correlation coefficients, the separation was fine.
Keywords:aromas  apple juice  GC  analysis
