Application of Olfactory Visualization Technology in Food Quality Analysis

Olfactory visualization technology is a new sensing technology established by imitating the mammalian olfactory system, including colorimetric sensing array, reaction chamber, image acquisition and data processing systems. This technology realizes the detection and discrimination of analytes by monitoring the reactions of volatiles of sample with the gas-sensitive colorimetric dyes array. The technology possesses high sensitivity and has great application potential in food quality analysis. This article summarized and reviewed the application of olfactory visualization techniques in food quality analysis, discussed the current status and prospected the future trend of this technology.
