Scaling Sensory Evaluation of Food

Abstract

Scaling describes the application of numbers, or judgments that are converted to numerical values, to describe the perceived intensity of a sensory experience or the degree of liking or disliking for some experience or product. Scaling forms the basis for the sensory method of descriptive analysis. A variety of methods have been used for this purpose and with some caution, all work well in differentiating products. This chapter discusses theoretical issues as well as practical considerations in scaling.
