DYNAMIC LIGHT-SCATTERING - APPLICATIONS TO FOOD SYSTEMS

The development of the laser in the 1960s has encouraged a remarkable proliferation in light scattering experiments. Coupled with the rapid advances in photon counting equipment and fast, on-line, computer proc essing, new spectroscopies such as dynamic light scattering (DLS) have become common tools in science laboratories. In this chapter, a brief overview of dynamic light scattering is first provided. This will be followed by a review of the basic concepts underlying the technique, t he technical aspects that are of particular concern and, finally, appl ications of DLS to scientific problems in food science.
