The purpose of this book is to provide an advanced and quantitative approach to sensory science problems.? Too often mainstream sensory evaluation, as practiced in the foods and consumer products industries, is primarily concerned with day-to-day tests of pairs of products.? Although such testing is often necessary, one can lose sight of the underlying models and theory for product discrimination and quantitative description upon which our test designs and statistical methods are based.? Sensory evaluation procedures have their roots in classical psychophysics and statistical methods.? This book will provide a quantitative basis for models underpinning sensory testing for the advanced student and sensory scientist.? Topics that lend themselves to quantitative analysis such as the study of mixture interactions, shelf life modeling and threshold estimation are treated.?? This book is not intended as a guide to data analysis and sensory statistics alone, but treats quantitative modeling in a broader view.? Methods that are primarily qualitative, such as focus groups, fuzzy-front end methods and other consumer-driven idea discovery techniques are not within the scope of this book. Several texts exist on sensory evaluation.? These are primarily aimed at the introductory student level.? Several statistical texts for sensory data also exist.? These do not deal with quantitative modeling issues such as Thurstonian scaling.? This book will attempt to place all the quantitative models for sensory phenomena and sensory data in one work.? Rather than focus simply on data handling issues, the book will have a psychological emphasis, for example, why experimental designs that use panelists as their own controls are often more powerful for finding product differences.
