Quality assessment of Chinese liquor with different ages and prediction analysis based on gas chromatography and electronic nose

Abstract The economic value of Chinese liquor is closely related with its age. Results from gas chromatograph (GC) analysis indicated that 8 dominant compounds were decreased with the increase of liquor age (0 to 5 years) while ethyl lactate was found to be the most stable dominant compound as no si...
