There have been an increasing number of cases of substitution of organic produce by conventially grown produce driving the need for robust methods to authenticate organically grown produce. Metabolomics to distringuish organic produce from conventially grown produce has been used for some time. This review examines the latest applications, advantages, challenges and future perspectives of HRMS based targeted and untargeted metabolomics for discrimination between organic and conventional crops. It concludes that data from combined techniques, such as untargeted and targeted metabolomics or metabolomics and stable isotope analysis, can improve the robustness of discriminative models, but they require further validation.

The main authenticity issues associated with EVOO’s quality involve the organoleptic properties (EVOO or defective), mislabelling of production type (organic or conventional), variety and geographical origin, and adulteration. Greek researchers have reviewed the various "omics" (mainly genomics and metabolomics) using HRMS with various chemometric tools presenting the various workflows to verify critical aspects of olive oil authenticity.
