Geographically shaped products are more preferred amongst the customers. The food authentication has gained more interest because this authenticity gives the high quality and high value properties to the products. The geographic origin of cheese is an important criterion in many consumers’ decisions concerning their choices. According to authorities, products bearing the name of origin cannot be produced outside the geographical region to which they belong. Determination of authenticity of the products is very critical to protect the products uniqueness. Ezine cheese is one of the most popular and most delicious cheese in Turkey and therefore, it is legally mandatory that Ezine cheeses must be labelled with the geographic origin. The most important difference of Ezine cheese from other white cheeses is that the milk used in the production of this cheese is supplied from a specific region. The definition of Ezine cheese in the registration document is as follows: “Ezine cheese is produced in Ezine, Bayramic and Ayvacik districts of Çanakkale City, located in the northern and western parts of the Kaz Mountains, and some villages of the central district and Çan district. Ezine cheese is produced by mixing the milk samples at a certain rates which are obtained from goats, sheep and cows fed with the natural vegetation and water sources of the specified geography. This rate must be at least 40% for goat milk, 45–55% for sheep milk and 15% for cow's milk.” There is an increasing interest to develop new techniques which provide more reliable results with a shorter time so multi-elemental fingerprinting could be a useful tool in determining the geographic origins of produced the Ezine cheese. The elemental content of the cheese samples is a clue for indicating elemental composition of milk samples from where the they were obtained and which kind of milk(s) were (goat, cow, sheep) used for cheese production. After analyses, obtained results were statistically processed to check the geographic origins of cheeses. On the other hand, the multi-elemental profiling of an Ezine cheese sample after ICP-MS analysis is very important especially for deciding whether a sample is original product or not. In this study, we aimed to determine the geographic origins of cheese samples produced in different regions in Turkey. Thus, the multi-elemental profiles of the samples were evaluated after analyzing by Inductively Coupled Plasma-Mass Spectrometry (ICPMS). The target elements were K, Ca, Ti, Mn, Si, P, S, Cl, Fe, Zn, Br, Rb, and Sr for analyses.
