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.
The book is designed as a text for undergraduate and graduate courses in sensory evaluation and as a reference for industrial practitioners. It covers all the basic techniques of sensory testing, from simple discrimination tests to home use placements for consumers. It provides a practical guide to how tests are conducted and, for the reader who wishes a deeper understanding, provides the fundamental psychological and statistical theories that form the basis and rationale for sensory test design. Statistics used in sensory evaluation are demonstrated as integrated applications in the context of appropriate sensory methods and are also presented as a stand-alone material in appendixes. Statistical applications are tailored to common and relevance are obvious, and space is not wasted on designs or analyses that are not suitable for data collection from human observers. The text presents divergent philosophies in a balanced manner. Chapters are constructed so that beginning students who want only practical aspects of conducting sensory tests will find clear instructions on how tests should be conducted. Advanced students and practitioners will profit from the detailed section on rationale and sensory evaluation issues. "It covers the entire spectrum of sensory analysis. I have read many books on this intriguing subject, but this is the Rolls-Royce." a?? Aubrey Parsons, governing council member, International Union for Food Science and Technology
This book is a practical guide to sensory evaluation methods and techniques in the food, cosmetic and household product industries. It explains the suitability of different testing methods for different situations and offers step-by-step instructions on how to perform the various types of tests. Covering a broad range of food and non-food product applications, the book is designed to be used as a practical reference in the testing environment; a training manual for new recruits into sensory science, and a course book for students undertaking industrial training or academic study.
Sensory Evaluation of Food: Statistical Methods and Procedure covers all of the basic techniques of sensory testing, from simple discrimination tests to home use placements for consumers. Providing a practical guide to how tests are conducted, the book explores the fundamental psychological and statistical theories that form the basis and rationale for sensory test design. It also demonstrates how statistics used in sensory evaluation can be applied in integrated applications in the context of appropriate sensory methods, as well as in stand-alone material in appendices. Offering a balanced view of diverse approaches, this is an essential guide for industry professionals and students.
Sensory evaluation is a scientific discipline used to evoke,measure, analyse and interpret responses to products perceivedthrough the senses of sight, smell, touch, taste and hearing. It isused to reveal insights into the way in which sensory propertiesdrive consumer acceptance and behaviour, and to design productsthat best deliver what the consumer wants. It is also used ata more fundamental level to provide a wider understanding of themechanisms involved in sensory perception and consumer behaviour. Quantitative Sensory Analysis is an in-depth and uniquetreatment of the quantitative basis of sensory testing, enablingscientists in the food, cosmetics and personal care productindustries to gain objective insights into consumer preference data– vital for informed new product development. Written by a globally-recognised learer in the field, this book issuitable for industrial sensory evaluation practitioners, sensoryscientists, advanced undergraduate and graduate students in sensoryevaluation and sensometricians.
Essentials of Food Science covers the basics of foods, food science, and food technology. The book is meant for the non-major intro course, whether taught in the food science or nutrition/dietetics department. In previous editions the book was organized around the USDA Food Pyramid which has been replaced. The revised pyramid will now be mentioned in appropriate chapters only. Other updates include new photos, website references, and culinary alerts for culinary and food preparation students. Two added topics include RFID (Radio frequency ID) tags, and trans fat disclosures. Includes updates on: food commodities, optimizing quality, laws, and food safety.
Methods to Assess Quality and Stability of Oils and Fat-Containing Foods is a valuable and unique resource for food scientists and oil chemists, a welcome addition to the libraries of scientists working in product development and quality control.
Abstract: Basic information is provided for food technologists, flavor chemists, and other food-related professionals, covering major flavor-allied topics; these include: the flavor industry; the flavor chemist; flavor research; flavor chemistry; food colorants; flavor manufacturing methods; application of flavor quality assurance; flavor legislation in the US and abroad; worldwide labeling regulations; and toxicology and consumer safety. Available data are provided on: natural flavoring materials (e.g., alliaceous and fruit flavors, herbs, spices, essential oils); 325 plant materials, principal essential oils, and organic chemicals used in flavorings; synthetic flavors; aromatics; GRAS flavorings; and 350 flavor formulations. A bibliography on flavoring materials which occur naturally or as a result of processing is included. The legalized exemption of certain food additives (including flavoring additives) from US tolerance requirements is highlighted separately. Over 3000 literaturereferences are provided throughout the material. (wz).
The recording and analysis of food data are becoming increasingly sophisticated. Consequently, the food scientist in industry or at study faces the task of using and understanding statistical methods. Statistics is often viewed as a difficult subject and is often avoided because of its complexity and a lack of specific application to the requirements of food science. This situation is changing – there is now much material on multivariate applications for the more advanced reader, but a case exists for a univariate approach aimed at the non-statistician. This book provides a source text on accessible statistical procedures for the food scientist, and is aimed at professionals and students in food laboratories where analytical, instrumental and sensory data are gathered and require some form of summary and analysis before interpretation. It is suitable for the food analyst, the sensory scientist and the product developer, and others who work in food-related disciplines involving consumer survey investigations will also find many sections of use. There is an emphasis on a ‘hands on’ approach, and worked examples using computer software packages and the minimum of mathematical formulae are included. The book is based on the experience and practice of a scientist engaged for many years in research and teaching of analytical and sensory food science at undergraduate and post-graduate level.
