Abstract：A new strategy was proposed in this work to meet the urgent needs of the rapid discrimination technology of Chinese liquor brands. The ultraviolet spectra were used as the inputs, the moving window correlation coefficient was applied as the analytical method, and the Haizhilan spirit was used as the research object. The results showed that the quality of different batches of Haizhilan spirit was consistent in the experimental wavelength interval. The correlation coefficient of ultraviolet spectral original data and the moving window correlation coefficient spectral were all above 0.99. The processing techniques and raw materials of Haizhilan spirit and the other series of Yanghe spirits belonging to the same company had a higher similarity. It was difficult to quantitatively discriminate their brands only by using the ultraviolet spectral original data with correlation coefficient method. The moving window method could effectively improve the spectral detail differences, highlight the shape, intensity and trend differences of the spectral feature bands, so it could enhance the ability of the experimental spectra to identify and analyze the fine structure. After an overall investigation, the moving window correlation coefficient combined with ultraviolet feature spectra (270~295 nm) improved the differences among Yanghe spirits, and then Haizhilan spirit could be discriminated from the other Yanghe spirits with high similarities. Six brands of Chinese liquor and ethanol as the control groups were used to further demonstrate the feasibility of this approach. The innovation of this work is to propose a novel analytical idea for rapid identification of the Chinese liquor brands based on the moving window correlation coefficient spectral method. This method also has the advantages of rapidity, simplicity, and has a great potential in the quality and safety discrimination of other foods.
