Near infrared spectroscopy has been widely used as an analytical tool in the dairy industry since the 1980s. NIR use has progressed as instruments have evolved over time. Today there are fleets of networked instruments using generic calibrations across broad product classes for at- and in-line applications. More recently NIR has found application for food safety applications as well, increasingly using non-targeted approaches. However the relevant strengths and weaknesses of NIR must be thoroughly understood in these challenging applications.
