Abstract: Waste oil is one of the food safety problem which people pay more attentiorto the complexity and non-quantification of waste oil brings great difficulties to its detection. This article introduced the physical and chemical properties of the waste oil, introduced the detection technology based on different physical or chemical properties of the waste oil, and then compared and summarized the advantages and disadvantages of several typical waste oil detection technologies. The spectrum technology has high sensitivity and accuracy, so the spectrum detection technology was mainly introduced from fluorescence spectrum, Raman spectrum, Fourier transform infrared spectrum and terahertz spectrum. By comparing various detection technologies, it concluded that the fluorescence spectrum will have great potential in the detection of waste oil in the future.

Key words: waste oil, detection, spectral characteristics
