Abstract Authentication of geographical origin of food has become indispensable because of the increased awareness of consumers and globalization of food market. A preliminary study was done to establish correlation between isotopic composition (δ13C, δ15N) and geographical origin of the wheat samples obtained from different regions of cultivation. Twenty samples of wheat were collected from adjoining states of India and their δ13C as well as δ15N values were determined using isotopic ratio mass spectrometry (IRMS). The mean δ13C values for different states ranged from −24.62% to −27.84% and were significantly different among the states at p
