掺伪芝麻油快速检测方法的研究

Study on Rapid Detection Method of Adulterated Sesame Oil

通过单因素及正交试验确定了掺伪芝麻油快速检测的最佳试验条件并制出标准比色卡。结果显示,在盐酸浓度为37%,用量450μL,显色剂用量350μL,反应时间30 s条件下,对待测样品进行检测,颜色鲜艳,梯度明显,可以快速对芝麻油的纯度进行判断。该方法试验操作较为简单,携带方便,适合广泛应用。

Through single factor and orthogonal experiment, determine the best experimental conditions for spurious sesame oil rapid test kit and produce a standard colorimetric card. The results showed that the sample to be measured under the condition of hydrochloric acid concentration of 37%, the amount of 450 μL, the amount of color developer 350 μL, reaction time 30 s, the color was bright and the gradient was obvious. The experimental operation was relatively simple, portable and suitable for a wide range of applications.
