Description
Summary:Spectroscopic methods are efficient tools for food authentication due to the advantages of high sensitivity, rapidness, simplicity and their convenience. The combined used of spectroscopic methods and linear discriminant analysis has provided powerful tools for detecting food fraud. This review discusses their operational details, advantages and disadvantages. •Food authentication deals with fraud or verification of its geographic and biological origin.•Analytical tools must be available throughout the food chain to verify the nature of food.•Chemometrics provides powerful tools in the analysis of spectroscopic data.•There are mainly targeted (metabolomics) and non-targeted (profiling) approaches.•There is a need for tailored strategies to solve a large number of food authentication issues.
