This guide explains how to plan, execute, complete, analyze, interpret, and report sensory evaluation studies. Chapters outline the steps in a sensory evaluation project; the human senses and sensory attributes like appearance, odor, and flavor; equipment, tasters, and samples; psychological pitfalls that invalidate studies; how sensory responses can be measured in quantitative terms; guidelines for selecting an approach; common sensory tests for difference; attribute tests; thresholds and just-noticeable differences; the selection and training of panelists; descriptive testing; affective tests; classic qualitative and quantitative methods for testing with consumers; and the latest methods used by sensory researchers in consumer products companies. This edition has been revised and updated with a more intuitive organization, adapted statistical methods to connect with more basic consumer methodology, and rearranged material to reflect advances in internet testing. It has new time-intensity testing methods; new problems; new chapters on tetrad testing, advanced sensory processes, quality control testing, advertising claims, and business challenges; new material on mapping and sorting, graph theory, multidimensional scaling, and flash profiling techniques; explanations of theories of integrity, amplitude, and balance and blend; an expanded chapter on the Spectrum method of descriptive sensory analysis; and updated appendices for Spectrum method scales.
