摘要
根据Villavecehia试验原理,研究建立了1种简便、灵敏、快速、准确的分光光度定量测定芝麻油纯度方法.方法线性范围0～0.040 g芝麻油,r＞0.999,最小检出量0.0006 g芝麻油;精密度0.54～1.58,变异系数0.73%～3.32%.菜籽油、大豆油、玉米油、油菜籽油、精炼棉籽油、花生油等6种食用油和样品芝麻油加标回收率99.1%～104.6%.
A simple, sensitive, rapid and accurate procedure for quantitative determination of the purity of sesame oil has been established using spectrometry and based on the principles of Villavecehia. Its linear inspection range is from 0 to 0.40 g with a minimum value of 0. 000 6 g, and its precision is in the range of 0.54 to 1.58, with a coefficient of variation of 0.73% to 3.32%. When this procedure was used to make setting level test for sampled sesame oil and other six kinds of oil （ rapeseed oil, soybean oil, maize oil, oil - tea camel- lia seed oil, refined cotton seed oil and peanut oil）, the recovery rate was up to 99.1% to 104.6%.
