Various samples of coriander power (CS1, CS2, CS3, CS4 and CS5) were collected from local market in Kanpur city, Uttar Pradesh. The identification of adulterant in coriander powder samples using chemical methods and Fourier-transform infrared (FTIR) spectroscopy technique was used. The results revealed that the adulteration in most of the coriander powder under investigation.
