Application of Spectral Techniques in Quality Detection of Vegetable Oils

Many methods have been used widely in quality detection of vegetable oils,including sensory evaluation,physical and chemical analysis,mass spectrometry,chromatography,chromatography mass spectrometry,etc.However,performing these traditional methods usually requires time consuming sample preparation and other complex processes.To meet the demands for developing industries and growing markets,a detection technique with simpler process and lower cost is needed in food quality detection.With the reduction of manufacturing cost and the improvement of performance,spectroscopy has been developing rapidly in the last decade for its rapidness,accuracy and non destructive application.The spectral detection of vegetable oil quality has become a hot research topic,and a vast application of spectral techniques could be expected in food detection.The recent research progresses of vegetable oil quality detection is updated in this review based on spectral techniques.Indicators for evaluating the quality of vegetable oils are introduced in the beginning.Applications of different spectral techniques in vegetable oil quality detection,such as infrared spectroscopy,Raman spectroscopy,fluorescence spectroscopy,ultraviolet spectroscopy,etc were highlighted afterwards.Furthermore,the current bottlenecks as well as the application prospects of spectral techniques in vegetable oil quality detection are predicted.
