Abstract :Osmancık-97 is an important Turkish rice cultivar with high quality and it is often targeted for theadulteration with imported varieties. Multiple elements and stable isotope profile were investigated fortheir use to trace geographical origin of Turkish rice insert ignore into journalissuearticles values(Oryza sativa L.); samples. Fourteen key variablesCopper insert ignore into journalissuearticles values(Cu);, Zinc insert ignore into journalissuearticles values(Zn);, Iron insert ignore into journalissuearticles values(Fe);, Nickel insert ignore into journalissuearticles values(Ni);, Chromiuminsert ignore into journalissuearticles values(Cr);, Aluminium insert ignore into journalissuearticles values(Al);, Strontium insert ignore into journalissuearticles values(Sr);, Carboninsert ignore into journalissuearticles values(C);, Nitrogen insert ignore into journalissuearticles values(N);, Oxygen insert ignore into journalissuearticles values(O); and Hydrogen insert ignore into journalissuearticles values(H); contents and stable isotopes insert ignore into journalissuearticles values(carbon, nitrogen, andoxygen isotopic compositions); were identified by `stepwise` canonical discriminate analysis insert ignore into journalissuearticles values(CDA); ofTurkish rice. For all samples δ13C, δ15N, and δ18O values are contributed from -25.99 to -28.15‰, +3.27to +7.71‰ and +22.32 to 27.08‰, respectively. Thus, the comparison of isotope profile and multipleelement contents of the rice is a good tool for rice authentication
