From the reviews of the second edition: "This volume is an academic text, bringing together theory, methodologies and analysis techniques of sensory evaluation and references to thousands of research articles on sensory science in a logical and practical manner. ... its primary aim is as a textbook for university-level sensory science modules. ... also serves as an over-arching technical manual and resource for practicing food and drink technologists and sensory scientists. ... The book is essential reading for those in the sensory evaluation sphere and serves as an excellent and practical reference." (Patricia Stefanowicz, Journal of Wine Research, Vol. 24 (1), 2013)
