典型食用油的荧光光谱特性与拉曼光谱特性研究

摘要

A system based on spectrum analysis for cooking oil testing is established by combining laser- induced- fluoresce and laser-Raman technology. Several oil samples were tested by this system. The measurement results showed that there are rich information of fluoresce and Raman spectrum for the oil samples and there are obvious difference betweenthe fluoresce spectrums for these samples. The sysytem can be used as a reference for oil pollution classification and recognition. This technology can be used for in-situ monitoring equipments.%本文结合激光诱导荧光技术和激光拉曼技术,建立了基于光谱分析的食用油快速分析系统,并利用此系统测量了多种油类样品的荧光光谱及拉曼光谱信号,结果表明,油类样品存在极为丰富的荧光信号和拉曼信号,不同种类的油类样品信号存在较大差异。因此,食用油的激光诱导荧光光谱和拉曼光谱可以作为食用油安全快速检测的一种依据,适于发展快速监测仪器。
