Abstract:In order to establish a millet origin of the rapid detection technology， better maintenance of local fa－ mous millet brand benefits， near infrared diffuse reflectance spectroscopy was used to identify the origin of mil－ let in different states. A total of 144 millet samples from the main producing areas of Zhaoyuan and Zhaozhou were selected， and the near infrared diffuse reflectance spectroscopy combined with stoichiometry was used to study the origin of millet in different states. The results showed that the qualitative analysis model established by the factorization method in the whole wavelength range and the quantitative analysis model established by partial least squares（PLS）in the characteristic band range， and the correct identification rate of millet kernel and mil－ let powder in Zhaoyuan and Zhaozhou two millet main producing areas was above 90 %， and the correct predic－ tion rate of millet powder model was higher than that of millet kernel. Therefore， the application of near infrared diffuse reflectance spectroscopy to the different status of millet origin traceability of the rapid identification of a certain feasibility.
