Available in PDF, EPUB and Kindle. Book excerpt: Sensory evaluation is the perception science of the food industry. Sensory data can be costly to obtain and so gleaning the most information possible from the data is key. Increasingly, value is added to sensory evaluation by the use of statistics, especially to improve the quality of product development and to make the most of market research. Nonparametrics for Sensory Science is written to complement existing parametric methodology. Nonparametric methods are appropriate when facts are only available in nominal or ordinal form, and when the model assumptions necessary for parametric procedures do not hold. Author Rayner and his colleagues consider problems including the most commonly occurring and important experimental designs: the one-sample, k-sample, blocked samples, samples with factorial structure and samples with correlation structure. Innovative new techniques are outlined and complemented with real examples. Techniques described may be applied to data where the traditional, most frequently applied nonparametric tests, such as the Kruskal-Wallis, the Friedman and the Spearman tests, are applied. Those familiar with traditional nonparametric testing will be able to update their knowledge, acquiring powerful new methods. Those without prior knowledge of nonparametric testing will be able to acquire that knowledge through this book. Aimed at sensory scientists and statisticians interested in nonparametrics, the techniques of Nonparametrics for Sensory Science are of broad general interest, but are of particular interest in sensory evaluation applications.

Download or read book Multivariate Analysis of Data in Sensory Science written by T. Naes and published by Elsevier. This book was released on 1996-02-01 with total page 365 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Sensory Evaluation of Food written by Harry T. Lawless and published by Springer Science & Business Media. This book was released on 2010-09-27 with total page 603 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Nonfood Sensory Practices written by Anne-Marie Pense-Lheritier and published by Woodhead Publishing. This book was released on 2021-08-28 with total page 392 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sensory evaluation is applied in very diverse and sometimes unexpected sectors. Nonfood Sensory Practices aims to show how sensory professionals from sectors other than food have embraced sensory evaluation methods for product development and communication of their products’ sensory properties. This book is thus intended as a first assessment of what is happening in nonfood sectors. It will open perspectives to those sensory professionals who wish to apply and adapt their expertise in food sensory science to other types of products, as well as to those working in nonfood sectors but with lesser background in sensory evaluation. Many nonfood products are intrinsically complex. They can be used in diverse ways, often in strong interaction with context and – unlike food – over several hours, days or months. This book shows how sensory professionals have adapted to these specificities, not to mention specific needs in terms of panel management and different ways to deal with consumers, users, customers or even sometimes with patients. First chapters present general methodological principles that will allow readers to fully apprehend the use of sensory practices. Then, contributions from many professionals in nonfood sectors will help to realize and promote the potential added value of sensory evaluation to their own field of application. Presents methodological specificities and solutions for the sensory evaluation of non-food products Includes case studies that help readers understand how to adapt food-centric sensory methods developed for non-food applications Triggers new ideas and further useful developments for the sensory evaluation of food products and the study of food-related consumer behaviors

Download or read book Food Biodeterioration and Preservation written by Gary S. Tucker and published by John Wiley & Sons. This book was released on 2008-04-30 with total page 264 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biodeterioration can be defined as the breakdown of food by agents of microbiological origin, either directly or from products of their metabolism. Microbiological sources can be present in foods prior to packaging or on the surfaces of packaging materials. The shelf life and safety of the food will depend on the type and quantity of microorganism, as well as the hurdles to their growth offered by various preservation techniques. This book discusses how the agents of food biodeterioration operate, and examines the commercially-used industrial methods available to control them, allowing the production of safe and wholesome foods. There is an emphasis on the equipment employed to carry out the various methods of preservation. The introductory chapter describes in detail the microorganisms and mechanisms of food breakdown intrinsic to various key food types; dairy, meat and fish, fruit, and vegetables. Direct microorganism action will be covered in addition to enzymatic breakdown. The second chapter addresses HACCP, including food safety legislation. Subsequent chapters outline the principal, commercially-used methods of preserving foods. These chapters follow a common structure: theoretical background; flow sheets of operations; food preparation/processing equipment; special features of hygiene; packaging; shelf life; and product safety. Food Biodeterioration and Preservation is directed at food scientists and technologists in industry and academia. Since it covers all the commonly-used methods of food preservation, it will be relevant across the entire food manufacturing industry.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book The BRC Global Standard for Food Safety written by Ron Kill and published by John Wiley & Sons. This book was released on 2011-08-24 with total page 299 pages. Available in PDF, EPUB and Kindle. Book excerpt: "This book offers companies in the food industry the first comprehensive guide to preparing for the Global Standard Audit." Beverage and Food World, May 2009 BASED ON ISSUE 5 OF THE BRC STANDARD The British Retail Consortium Global Standard for Food Safety was originally conceived to meet an increasing demand for a unified standard to be used by the major retailers in the UK for their suppliers of "own label" food products. The system has proved so successful that it is now used throughout the food industry, and over 7000 food manufacturers worldwide already have the Standard. Companies are often unsure about how to approach attaining certification—often a demanding process, especially at the first attempt. Not only are there over 300 clauses to satisfy, there are also general concerns such as how to correct non-conformities within very specific deadlines. Even when their operations are actually quite satisfactory, many suppliers find themselves poorly prepared for the audit and do not perform as well as they might. This book offers companies in the food industry the first comprehensive guide to preparing for the Global Standard audit. Using over 600 real life examples, it enables manufacturers to ensure that the correct systems are in place to achieve the Standard and present themselves in the best way during the audit process. It also recommends the steps to take following the audit and how to correct non-conformities. The book is an essential resource for suppliers wishing to attain certification for the first time and those already in the scheme seeking to improve their grades. It is also of interest to certification bodies and consultants to the food industry.
