In recent years,people pay more and more attention to food safety. Flavors are closely related to our daily lives,and effective market regulation to ensure the authentication and safety is urgent. Stable isotope ratio mass spectrometry（ IRMS）,as one of the efficient methods to determine traceability of origin and authenticity,has been widely applied to food research in recent years. In this review,the basic principles of IRMS and mechanisms of stable isotope fractionation were briefly introduced. The research progress in flavors identification was summarized and a perspective of this technology has been discussed. The purpose of this paper is to promote the application of stable isotope mass spectrometry in flavors identification,and to promote the establishment and improvement of stable isotopic database and the identification system of flavors authenticity.
