建立了椰汁中4种香精的气相色谱检测方法。椰汁样品经硅藻土固相萃取柱净化后检测,4种香精在(1~100)μg/m L浓度范围内有较好的线性关系;该方法回收率为95.3%~110.5%,相对标准偏差为1.2%~2.5%,检出限为(0.2~0.5)mg/kg。此方法准确、可靠、灵敏度高,可以满足椰汁的日常检测。 A gas chromatographic method for the determination of four flavors in coconut milk was established. Coconut juice samples were purified by diatomaceous earth solid phase extraction column and tested. The four flavors had a good linear relationship in the concentration range of (1 ~ 100) μg / mL. The recoveries were 95.3% ~ 110.5% The standard deviation was 1.2% ~ 2.5%, the detection limit was (0.2 ~ 0.5) mg / kg. This method is accurate, reliable, high sensitivity, coconut juice can meet the daily test.
