This paper reviewed the applications of the spectral technologies, including the adulteration detection, nutrients detection，antibiotics detection, microbial contamination detection and product types identification in dairy and dairy products. Using Near-infrared spectroscopy, Raman spectroscopy and Hyperspectral imaging technique, the important applications and research advances of the quality detection and safety assessments in dairy and dairy products have been also reviewed. It was pointed out that the joint application of various technologies is the trend of future research.
