sensory evaluation of food statistical methods and procedures: Sensory Evaluation of Food Harry T. Lawless, Hildegarde Heymann, 2010-09-27 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. |
sensory evaluation of food statistical methods and procedures: Statistical Methods for Food Science John A. Bower, 2013-09-23 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 second edition of Statistical Methods for Food Science 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. This revised and updated second edition is accompanied by a new companion website giving the reader access to the datasets and Excel spreadsheets featured in the book.

sensory evaluation of food statistical methods and procedures: Guidelines for Sensory Analysis in Food Product Development and Quality Control Roland P. Carpenter, David H. Lyon, Terry A. Hasdell, 2012-12-06 Sensory testing has been in existence ever since man started to use his senses to judge the quality and safety of drinking water and foodstuffs. With the onset of trading, there were several developments that led to more formalized testing, involving professional tasters and grading systems. Many of these grading systems are still in existence today and continue to serve a useful purpose, for example in assessing tea, coffee, and wines. However, there has also been a growing need for methods for well-repli cated, objective, unbiased sensory assessment, which can be applied rou tinely across a wide range of foods. Sensory analysis seeks to satisfy this need. Sensory analysis is not new to the food industry, but its application as a basic tool in food product development and quality control has not always been given the recognition and acceptance it deserves. This, we believe, is largely due to the lack of understanding about what sensory analysis can offer in product research, development, and marketing and a fear that the discipline is too scientific to be practical. To some extent, sensory scien tists have perpetuated this fear by failing to recognize the industrial con straints to implementing sensory testing procedures. These Guidelines are an attempt to redress the balance. |

sensory evaluation of food statistical methods and procedures: Guidelines for Sensory Analysis in Food Product Development and Quality Control David H. Lyon, Mariko A. Francombe, Terry A. Hasdell, 2012-12-06 Sensory analysis is not new to the food industry, but its application as a basic tool in food product development and quality control has not been given the recognition and acceptance it deserves. This, we believe, is largely due to the lack of understanding about what sensory analysis can offer in product research, development and marketing, and a fear that the discipline is 'too scientific' to be practical. To some extent, sensory scientists have perpetuated this fear with a failure to recognize the constraints of industry in implementing sensory testing procedures. These guidelines are an attempt to redress the balance. Of course, product 'tasting' is carried out in every food company: it may be the morning tasting session by the managing director, competitor comparisons by the marketeers, tasting by a product 'expert' giving a quality opinion, comparison of new recipes from the product development kitchen, or on-line checking during pro duction. Most relevant, though, is that the people respon sible for the tasting session should know why the work is being done, and fully realize that if it is not done well, then the results and conclusions drawn, and their implications, are likely to be misleading. If, through the production of these guidelines, we have influenced some people suffi ciently for them to re-evaluate what they are doing, and why, we believe our efforts have been worthwhile. |
sensory evaluation of food statistical methods and procedures: Statistics for Sensory and Consumer Science Tormod Næs, Per Bruun Brockhoff, Oliver Tomic, 2011-06-20 As we move further into the 21st Century, sensory and consumer studies continue to develop, playing an important role in food science and industry.

sensory evaluation of food statistical methods and procedures: Sensory Evaluation in Quality Control Alejandra M. Munoz, 2013-11-11 This book addresses an important, but so far neglected, topic: the application of sensory evaluation to quality control. Although several articles have been pub lished that have discussed concepts of quality control/sensory evaluation (QC/sen sory) programs, Sensory Evaluation in Quality Control is the first publication that addresses this topic in a comprehensive and practical way. This book is com prehensive, in that it presents the sensory and statistical information that is needed to design and implement several types of QCfsensory programs at the plant level. The book is practical, in that it provides a step-by-step description of the complete process to implement such programs, and it illustrates this process through real examples encountered by various consumer products companies (e. g. , foods, personal care products, paper products). With this practical information, sensory and quality professionals can design and implement sound QC/sensory programs at the plant level. This book was developed to provide the sensory and quality professional with an overview and guide to apply, in a production facility, the unique techniques that are used to measure sensory responses. Therefore, the book is intended for QC and/or R&D personnel (e. g. , sensory managers and analysts, and quality profes sionals) in charge of implementing an in-plant program, as well as for the plant management and plant technical personnel (sensory coordinator and quality pro fessionals) who are ultimately responsible for the routine operation of the estab lished program. |

sensory evaluation of food statistical methods and procedures: Time-Dependent Measures of Perception in Sensory Evaluation Joanne Hort, Sarah E. Kemp, Tracey Hollowood, 2017-03-20 Sensory evaluation is a scientific discipline used to evoke, measure, analyse and interpret responses to products perceived through the senses of sight, smell, touch, taste and hearing. It is used to reveal insights into the way in which sensory properties drive consumer acceptance and behaviour, and to design products that best deliver what the consumer wants. It is also used at a more fundamental level to provide a wider understanding of the mechanisms involved in sensory perception and consumer behaviour. Sensory perception of products alters considerably during the course of consumption/use. Special techniques are used in product development to measure these changes in order to optimise product delivery to consumers. Time-Dependent Measures of Perception in Sensory Evaluation explores the many facets of time-dependent perception including mastication and food breakdown, sensory-specific satiety and sensory memory. Both traditional and cutting-edge techniques and applications used to measure temporal changes in sensory perception over time are reviewed, and insights into the way in which sensory properties drive consumer acceptance and behaviour are provided. This book will be a valuable resource for sensory professionals working in academia and industry, including sensory scientists, practitioners, trainers and students; and industry-based researchers in QA/QC, R&D and marketing. |

sensory evaluation of food statistical methods and procedures: Food Taints and Off-Flavours M.J. Saxby, 2012-12-06 Contamination of food with extremely low levels of certain compounds can cause an unpleasant taste. This can result in the destruction of vast stocks of product, and very substantial financial losses to food companies. The concentration of the alien compound in the food can be so low that very sophisticated equipment is needed to identify the components and to determine its source. It is vital that every company involved in the production, distribution and sale of foodstuffs are fully aware of the ways in which contamination can accrue, how it can be avoided, and what steps need to be taken in the event that a problem does arise. This book provides the background information needed to recognize how food can become tainted, to draw up guidelines to prevent this contamination, and to plan the steps that should be taken in the event of an outbreak. The new edition has been extensively revised and updated and includes substantial new material on the formation of off flavors due to microbiological and enzymic action, and on sensory evaluation of taints and off flavors A new chapter on off flavors in alcoholic beverages has been added.

sensory evaluation of food statistical methods and procedures: Fennema's Food Chemistry Srinivasan Damodaran, Kirk L. Parkin, Owen R. Fennema, 2007-09-18 This latest edition of the most internationally respected reference in food chemistry for more than 30 years, Fennema’s Food Chemistry once again meets and surpasses the standards of quality, comprehensive information set by its predecessors. This edition introduces new editors and contributors, who are recognized experts in their fields. All chapters reflect recent scientific advances and, where appropriate, have expanded and evolved their focus to provide readers with the current state-of-the-science of chemistry for the food industry. The fourth edition presents an entirely new chapter, Impact of Biotechnology on Food Supply and Quality, which examines the latest research in biotechnology and molecular interactions. Two former chapters receive extensive attention in the new edition including Physical and Chemical Interactions of Components in Food Systems (formerly “Summary: Integrative Concepts”) and Bioactive Substances: Nutraceuticals and Toxicants (formerly “Toxic Substances”), which highlights bioactive agents and their role in human health and represents the feverish study of the connection between food and health undertaken over the last decade. It discusses bioactive substances from both a regulatory and health standpoint. Retaining the straightforward organization and detailed, accessible style of the original, this edition begins with an examination of major food components such as water, carbohydrates, lipids, proteins, and enzymes. The second section looks at minor food components including vitamins and minerals, colorants, flavor, and additives. The final section considers food systems by reviewing basic considerations as well as specific information on the characteristics of milk and the postmortem physiology of edible muscle and postharvest physiology of plant tissues. Useful appendices provide keys to the international system of units, conversion factors, log P values calculation, and the Greek alphabet. |
