As we move further into the 21st Century, sensory and consumer studies continue to develop, playing an important role in food science and industry. These studies are crucial for understanding the relation between food properties on one side and human liking and buying behaviour on the other. This book by a group of established scientists gives a comprehensive, up-to-date overview of the most common statistical methods for handling data from both trained sensory panels and consumer studies of food. It presents the topic in two distinct sections: problem-orientated (Part I) and method orientated (Part II), making it to appropriate for people at different levels with respect to their statistical skills. This book succesfully: Makes a clear distinction between studies using a trained sensory panel and studies using consumers. Concentrates on experimental studies with focus on how sensory assessors or consumers perceive and assess various product properties. Focuses on relationships between methods and techniques and on considering all of them as special cases of more general statistical methodologies It is assumed that the reader has a basic knowledge of statistics and the most important data collection methods within sensory and consumer science. This text is aimed at food scientists and food engineers working in research and industry, as well as food science students at master and PhD level. In addition, applied statisticians with special interest in food science will also find relevant information within the book.

The state-of-the-art of multivariate analysis in sensory science is described in this volume. Both methods for aggregated and individual sensory profiles are discussed. Processes and results are presented in such a way that they can be understood not only by statisticians but also by experienced sensory panel leaders and users of sensory analysis. The techniques presented are focused on examples and interpretation rather than on the technical aspects, with an emphasis on new and important methods which are possibly not so well known to scientists in the field. Important features of the book are discussions on the relationship among the methods with a strong accent on the connection between problems and methods. All procedures presented are described in relation to sensory data and not as completely general statistical techniques. Sensory scientists, applied statisticians, chemometricians, those working in consumer science, food scientists and agronomers will find this book of value.

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

According to European legislation, extra virgin is the top gradeof olive oils. It has a superior level of health properties andflavour compared to virgin and refined olive oils. Mediterraneancountries still produce more than 85% of olive oil globally, butthe constant increase of demand for extra virgin olive oil has ledto new cultivation and production in other areas of the world,including California, Australia, China, South Africa and SouthAmerica. At the same time, olive oil’s sensory properties andhealth benefits are increasingly attracting the attention andinterest of nutritionists, food processors, manufacturers and foodservices. Progress and innovation in olive cultivation, harvestingand milling technologies as well as in oil handling, storage andselling conditions make it possible to achieve even higher qualitylevels than those stipulated for extra virgin oils. As aconsequence, a new segment – excellent extra virgin oliveoils – is increasingly attracting the attention of the marketand earning consumers’ preference. The Extra-Virgin Olive Oil Handbook provides a completeaccount of olive oil’s composition, health properties,quality, and the legal standards surrounding its production. Thebook is divided into convenient sections focusing on extra virginolive oil as a product, the process by which it is made, and theprocess control system through which its quality is assured. Anappendix presents a series of tables and graphs with useful data,including conversion factors, and the chemical and physicalcharacteristics of olive oil. This book is aimed at people involved in the industrial productionas well as in the marketing and use of extra virgin olive oil whoare looking for practical information, which avoids overly academiclanguage, but which is still scientifically and technically sound.The main purpose of the handbook is to guide operators involved inthe extra virgin olive oil chain in making the most appropriatedecisions about product quality and operating conditions in theproduction and distribution processes. To these groups, the mostimportant questions are practical ones of why, how, how often, howmuch will it cost, and so on. The Extra-Virgin Olive OilHandbook will provide the right answers to these key practicalconsiderations, in a simple, clear yet precise and up-to-dateway.
