Abstract: Tracing the geographical origin of cereal grains is an important part of identifying their authenticity. Stable isotope and mineral element analysis have the advantages of high sensitivity and reliability, and the association of the information obtained with growing environmental conditions and planting methods followed by chemometric classification, discrimination and modelling allows to trace the geographical origin of cereal grains. In this article, we provide a systematic review of the recent advances over the past more than one decade in the application of stable isotope and mineral element analysis in tracing the geographical origin of cereal grains. Meanwhile, we discuss the problems existing in tracing the geographical origin of cereal grains, and propose the future prospects and research priorities for the application of stable isotope and mineral element analysis in this field.

Key words: cereal grains, geographic origin, stable isotope, mineral element
