A new volatiles-based differentiation method of Chinese spirits using longpath gas-phase infrared spectroscopy.

Highlights: [•] The volatile compounds of different brands of Chinese spirits differ with respect to their composition and concentration. [•] The results of the first study on Chinese spirits volatiles analysis using gas-phase infrared spectroscopy were reported. [•] This study demonstrated that different brands of Chinese spirits with the same flavour from the same origin can be differentiated. [Copyright &y& Elsevier]
