目的：开发一种能对回收油脂进行有效鉴别的简便、快捷新方法。方法采用马尔文激光粒度仪对27种未经使用食用油以及5种回收油脂中颗粒物粒度大小进行测定,并对此32种油中颗粒物的粒度大小及其分布范围进行比较。结果未经使用的27种食用油中颗粒物粒度平均峰值均小于10 nm,而5种回收油脂中颗粒物粒度平均峰值均大于300 nm。结论回收油脂中颗粒物粒度要大于食用油的颗粒物粒度,通过2类油脂中颗粒物粒度峰值的差异可以进行回收油脂鉴别。本文采用激光粒度仪鉴别回收油脂,无需对样品进行任何前处理,测试过程简便、快捷。

Objective To develop a new method for identification of waste oil by Zetasizer. Methods Marvel Zetasizer was explored to measure the mean diameter of the particles in 27 kinds of edible oil and 5 kinds of waste oil, and the particle size and the distribution of edible oil and waste oil were compared. Results It was found out that the mean diameter of edible oil was smaller than 10 nm, the particle size of waste oil was larger than 300 nm. Conclusion The results show that the mean diameter of waste oil is much larger than that of edible oil. According to difference of particle size of 2 kinds of oils, waste oil and edible oil could be distinguished by Zetasizer. This method of identifying waste oil by Zetasizer was non-pretreatment, rapid and convenient.
