Osmanc›k-97 is an important Turkish rice cultivar with high quality and it is often targeted for the adulteration with imported varieties. Multiple elements and stable isotope profile were investigated for their use to trace geographical origin of Turkish rice (Oryza sativa L.) samples. Fourteen key variables Copper (Cu), Zinc (Zn), Iron (Fe), Nickel (Ni), Chromium(Cr), Aluminium (Al), Strontium (Sr), Carbon (C), Nitrogen (N), Oxygen (O) and Hydrogen (H) contents and stable isotopes (carbon, nitrogen, and oxygen isotopic compositions) were identified by "stepwise" canonical discriminate analysis (CDA) of Turkish rice. For all samples δC, δN, and δO values are contributed from -25.99 to -28.15‰, +3.27 to +7.71‰ and +22.32 to 27.08‰, respectively. Thus, the comparison of isotope profile and multiple element contents of the rice is a good tool for rice authentication.
