There is a growing interest in industry in process control systems employing infrared methods. In the food sector, this interest has primarily been associated with near infrared (NIR) systems which have gradually moved from the laboratory environment to the factory floor. Mid infrared (MIR) methods are now becoming increasingly used and in the future may become extremely important as process control devices. The object of this chapter is to describe the current status of NIR and MIR process control technology, with special emphasis on developments that have affected the MIR region particularly. The future potential of infrared methods will also be considered.
