    Abstract:

    Objective: To establish a rapid method of classifying marking age and brand of Chinese rice wines, which was detected by gas chromatography-ion mobility spectrometry (GC-IMS). Method: The volatile organic compounds (VOCs) in 5-year marking age and 3 company brands Chinese rice wines samples were detected by GC-IMS method with automatic headspace sampling system and datas were processed with principal component analysis(PCA). Result: The amounts of volatile compounds in Chinese rice wines samples were obviously different, marking age and brand could be distinguished by the VOCs fingerprints, 3-5 years marking age "Guyuelongshan" rice wine samples could be quickly distinguished with 8-20 years marking age by the fingerprints, while it was difficult to distinguish difference between 3-year and 5-year marking age wine, between 8-year and 20-year marking age wine with this method. A improvement method to discriminate difference among all marking age and company brands wines were performed by measuring hue angle from VOCs fingerprints with photoshop software. There were no significant difference of ethyl acetate content among all the samples, and slightly change of dimethyl disulfide content, while remarkable differences were found in benzaldehyde, 3-methylbutyl acetate and 2-butanone among 7 samples, which could be used for distinguishing marking age and brand of the Chinese rice wine. Chinese rice wines could be classified accurately by PCA, and some interesting regularity were shown in the score plots with the help of PCA. Conclusion: GC-IMS combined with PCA was a useful and reliable technology for intuitive discriminating marking age and brand of Chinese rice wine, and it had potential wide application prospect in rice wine quality evaluation.
