"From the co-author of Sensory Evaluation of Foods, Principles and Practices, this lab manual is a fitting accompaniment to that text in an undergraduate or graduate course in sensory evaluation of foods. The manual includes introductory information, such as report formats (both academic and industrial), as well as a series of eleven full-length lab exercises suitable for a three-hour laboratory period. There are also four shorter exercises suitable for a traditional class period, and one group exercise suitable for a semester project in descriptive analysis and terminology building. Correct use of graphs, tables and statistics is emphasized in several sections. Each exercise includes both a student section and one for instructors and teaching assistants, which features detailed instructions with supplies, equipment, preparation procedures, ballots and data sheets. Each instructor section also includes "key to successful execution", which cover common mistakes and important details, designed to give the students the maximum opportunity for a rich learning experience. A group of statistical problem sets is included to reinforce common statistical analyses used with sensory data. Methods encountered include discrimination, descriptive, affective/hedonic, scaling, thresholds, panelist screening, shelf life and consumer questionnaires. Critical thinking and discussion questions are emphasized above and beyond the rote learning of a specific procedure. For classes that may be offered to less advanced students, suggestions are made in the instructor sections on how the exercise or report can be simplified. The exercises were compiled and refined over two decades and used in an upper level course in sensory testing at Cornell University."--

Laboratory exercises are a necessary part of science education. They enable students to better understand the principles discussed in lectures, and provide them with hands-on experience of the practical aspects of scientific research. The purpose of this book is to provide students and instructors with a time-tested set of lab exercises that illustrate the common sensory tests and/or sensory principles used in evaluation of foods, beverages and consumer products. The appendices will also include a set of simple problem sets that can be used to teach and reinforce basic statistical tests. Approximately twenty years ago the Sensory Evaluation Division of the Institute of Food Technologists sponsored the preparation of a set of exercises titled “Guidelines for Laboratory Exercises for a Course in Sensory Evaluation of Foods,” edited by one of the co-authors (Heymann). This book will provide additional materials from the second author (Lawless), as well as other instructors, in a uniform format that can be easily adopted for course use. Most importantly, the lab exercises will complement the flagship textbook in the field, Sensory Evaluation of Foods: Principles and Practices, 2E, also by Lawless and Heymann and published by Springer. Possible course adoption of the main text along with the lab manual should enhance the sales of these materials.

The ?eld of sensory science has grown exponentially since the publication of the p- vious version of this work. Fifteen years ago the journal Food Quality and Preference was fairly new. Now it holds an eminent position as a venue for research on sensory test methods (among many other topics). Hundreds of articles relevant to sensory testing have appeared in that and in other journals such as the Journal of Sensory Studies. Knowledge of the intricate cellular processes in chemoreception, as well as their genetic basis, has undergone nothing less than a revolution, culminating in the award of the Nobel Prize to Buck and Axel in 2004 for their discovery of the olfactory receptor gene super family. Advances in statistical methodology have accelerated as well. Sensometrics meetings are now vigorous and well-attended annual events. Ideas like Thurstonian modeling were not widely embraced 15 years ago, but now seem to be part of the everyday thought process of many sensory scientists. And yet, some things stay the same. Sensory testing will always involve human participants. Humans are tough measuring instruments to work with. They come with varying degrees of acumen, training, experiences, differing genetic equipment, sensory capabilities, and of course, different preferences. Human foibles and their associated error variance will continue to place a limitation on sensory tests and actionable results. Reducing, controlling, partitioning, and explaining error variance are all at the heart of good test methods and practices.

First published in 1999. This book is written in four parts. Part I 'Foundations', starts with Chapter 1 'What is a multisensory environment?' and provides a general introduction to the field. The MSE can be different things to different people. It can describe an actual space, or the impact that space has on an individual. Furthermore, it can be for adults or children, for recreation, leisure, therapy or education. Part II 'Design and construction' explores the what, who, why and how of the open-minded, Part III 'Curriculum development' begins with Chapter 8 'Curriculum development in the MSE. The final section, Part IV 'Future developments', consists of two chapters. The goal of Chapter 11 'Conducting research in the MSE' is to demystify research and thereby encourage all members of the transdisciplinary team to become actively involved in MSE related research; Chapter 12 'Where are we going?', the MSE is re-examined to identify possible ways this development could contribute to the increased pluralities that will constitute education in the twenty-first century.
