Principle and Applications of Colorimetric Sensor Technology

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 the chemo-responsive dyes, substrate materials, and data processing methods are discussed. In application, any type of food samples including solid, liquid food samples could be directly analyzed using colorimetric sensor array. Additionally, the recent development, and future research trends are also involved. The colorimetric sensor technology offers an exciting method to establish the correlation between the output of a colorimetric sensor technology and the odor components, thereby enabling visual quantification of odors.
