ABSTRACT Background: Chinese spirit Moutai is the typical representative of Chinese liquor and has a huge market value. But in order to pursue economic interests, the counterfeit Moutai spirit often appears in the market. Thus, there is an urgent demand for rapid and effective development of identification technology to discriminate the genuine and counterfeit Moutai spirit. Objectives: The aim of the study is to establish a simple and new strategy for discriminating the genuine and counterfeit Moutai spirit. Methods: In the research, the conventional ion mobility spectroscopy (IMS) and two-dimensional correlation IMS techniques are used to identify the genuine and counterfeit Moutai spirit, respectively. Results: The corresponding results show that the IMS of genuine and counterfeit Moutai spirit have some similarities and it is so difficult to distinguish between both of them. After using two-dimensional correlation IMS analysis, it can be extremely intuitive to distinguish the genuine and counterfeit Moutai spirit. Furthermore, compared with the conventional technique, namely the method relying on the oenophile’s sense of taste and of smell, to identify their differences and control integral quality. The novel discrimination strategy is simple, fast, and intuitive, and avoids the might hurt of counterfeit liquor to the tasting oenophile. Conclusions: This method could be used to discinminate the genuine and counterfeit Moutai spirit and has a great potential application in the quality and safely management of Moutai spirit.
