Measurement of Appearance Properties Other Than Colour

Abstract

This chapter is devoted to the specification and measurement of object properties other than colour. The properties are grouped under the headings of physical form, translucency, gloss, uniformity and pattern, temporal properties, and analysis of complex scenes. The principles of established techniques, together with relevant examples and applications are included. Suggestions for possible approaches have been made for those areas in which techniques are presently lacking. The examples quoted inevitably apply to specific foods or systems, but the methodology is widely applicable within (as well as outside) the industry.
