A Fourier transformed near-infrared (FT-NIR) method for rapid determination of cholesterol in dairy products was demonstrated. FT-NIR spectrum of pure cholesterol was characterized and the region between 3550 and 3650 cm-1 was found to be the most significant in cholesterol content determination. The FT-NIR method was found to accurately predict the cholesterol content in a variety of dairy products with r2 value greater than 0.98 and SEP estimates of less than 1.70. The FT-NIR procedure with suitable multivariate statistical model was further validated by recovery studies and compared with a conventional method. Results indicate that FT-NIR has the potential for rapid estimation of cholesterol.
