Combing machine learning and elemental profiling for geographical authentication of Chinese Geographical Indication (GI) rice

Abstract Identification of geographical origin is of great importance for protecting the authenticity of valuable agri-food products with designated origins. In this study, a robust and accurate analytical method that could authenticate the geographical origin of Geographical Indication (GI) product...
