The colorimetric sensor technology simulates human olfaction to analyze, identify and examine complex gas and volatility based on chem-responsive dyes. Unlike human olfaction and electronic noses, colorimetric sensor technology is more objective and not susceptible to interference. In additional, with the visualization, rapidity and non-destruction of analysis, colorimetric sensor technology has been increasingly applied in food science and industry. This book focuses on the colorimetric sensor technology and its major applications in food industry. Technical considerations associated with...
