芝麻油掺伪后定性与定量的研究

Qualitative and Quantitative Identification of Sesame Oil

目的意义:近年来,芝麻油掺假现象常见,对芝麻油掺假鉴别的研究就显得尤为重要。下文对芝麻油的检测进行验证。方法:硫酸氯仿显色定性鉴别、甲醇提取法定量鉴别。结果:发现芝麻油掺伪后定性分析中硫酸氯仿显色结果明显;定量分析中甲醇提取法可明确得出油样含油量。二者结合期望得到较好结果。结论:芝麻油的定性和定量实验具有一定参考价值。

Purpose and Significance: In recent years, sesame oil adulteration has become common, and the research on the identification of sesame oil adulteration is particularly important. The following verifies the detection of sesame oil. by methods: qualitative identification by chloroform sulfate color development, quantitative identification by methanol extraction method. Results: It was found that the color of chloroform sulfate was obvious in the qualitative analysis after adulteration of sesame oil;the methanol extraction method in the quantitative analysis can clearly determine the oil content of the oil sample. The combination of the two is expected to get better results. Conclusion: The qualitative and quantitative experiments of sesame oil have certain reference value.
