Abstract

The Ramer reasons for development of new in-line sensors for food quality, and includes examples of optical sensors for in-line measurement and automatic control. The development is described of a colour sensor, the Qual-Probe, in which illumination from modulated single wavelength sources (LEDs and IREDs) is projected towards a small region of food material while it is in motion during the manufacturing process. One or more detectors are used to collect the diffusely reflected light from the controlled sources, by methods which are self-compensating for changes in source power or ambient radiation.
