An Intellectual Electronic Nose System for Distinguishing Beer Brands

doi:10.7506/spkx1002-6630-201122037

Abstract

Abstract: In this paper, an intellectual electronic nose system that can rapidly distinguish beer brands is described. The system mainly consisted of data acquisition, modification and transmission unit, sensor array and gas chamber, and power and gas supply unit. Five different brands of beer were distinguished by the system in combination with the stochastic resonance data processing method with considerable avoidance of the negative effect of sensor baseline drift. Our results demonstrate that the system allows rapid and effective distinguishing of beer brands with good reproducibility and will therefore have a promising prospect for practical applications.

Key words: beer, electronic nose, stochastic resonance, correlation coefficient
