Woody edible oil has become one of the most popular and expensive edible oils in the market due to its high quality and healthful properties. However, it is prone to adulteration with cheaper oils by unscrupulous traders. Therefore, there is a need for the development of a rapid, intuitive, and non-destructive technique for authenticating woody edible oil. This review highlights the use of fluorescence spectroscopy as a non-destructive method for analyzing the quality of woody edible oil. Additionally, the review discusses the influencing factors of fluorescence in woody edible oil and its applications in quality control and geographical origin traceability.
Woody edible oil plays an increasingly important role in people's lives to become one of the most popular and expensive edible oil in the market to because of its high quality and healthful properties. It's more susceptible to adulteration with other cheaper oil by theses unscrupulous traders for high profits. Therefore, a rapid, intuition, and non-destructive techniques for woody edible oil authentication should be developed. The current traditional determination methods are tedious and destructive to detect woody edible oil. Fluorescence spectroscopy possesses the advantages of rapid, green, multi-mode, and low-cost analysis as soon as a non-destructive method can be used to analyze the quality of woody edible oil in agricultural sciences. It can be used to detect authentication of woody edible oil by combining fluorescence spectroscopy and chemometrics. However, to the best of our knowledge, a comprehensive review on fluorescence spectroscopy for the quality of woody edible oil remains to be published. In this review, the fluorescence influencing factors of woody edible oil, included the cultivars, extraction technologies and geographical origin have been emphasized and highlighted the applications of fluorescence spectroscopy in quality control and geographical origin traceability of woody edible oil. In addition, the application of fluorescence-transmittance imaging technology in woody edible oil has been addressed. In the future, fluorescence spectroscopy could be applied in the rapid detection and online detection of hazardous substances in woody edible oil by developing portable devices.
