This book is a practical guide to sensory evaluation methods and techniques, explaining the suitability of different testing methods for different situations and offering step-by-step instructions on how to perform the various types of test. Covering a broad range of product applications including food, beverages, personal care and household products, the book is spiral bound to allow for easy reference in the testing environment.
The objectives of the book are
* to provide a practical guide and laboratory manual on how to carry out sensory evaluation techniques
* to reach sensory practitioners, as well as sensory scientists, by using a simple, easy-to-read, easy-to-use format
* to be affordable to a wide audience who would not ordinarily be able to afford to purchase standard sensory text books, including students, technicians and practitioners in developing countries
* to cover the IFST PFSG accreditation scheme at foundation and intermediate levels
The book is suitable as a training manual, reference text, teaching aid and course book. Key audiences include sensory practitioners, junior sensory staff, sensory students and sensory trainers.
