The peroxides is an important indicator of the edible oil.A method for the determination of peroxides in peanut oil by the near-infrared spectroscopy was presented.The PLS was used to establish a mathematical model in the spectral region of 9 214~4 559 cm^-1 by using Fourier transform near-infrared spectroscopy.The main factorial number found by cross-validation was 9.The root mean square error of cross-validation(RMSECV) was 6.88×10^-4 g/mL.In this model,the correlation coefficient was 0.991.The standard deviation was 1.10×10^-4 g/mL.The inverse relative error determined by the mathematical model and the GB standard method is 1.77%.
