Laboratory Exercises For Sensory Evaluation

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.

Sensory Evaluation Practices, Fifth Edition, presents the latest developments and methods of sensory evaluation, including those on the front end of innovation, consumer acceptance/preference, multivariate statistical analysis, discrimination testing, descriptive analysis, sensory claims substantiation for advertising, and information management. Additionally, related social psychological methods, such as laddering, design thinking, emotional profiling, and applications of qualitative and consumer co-creation and immersive techniques are explored. This book will be an ideal reference for sensory professionals, technical managers, product specialists and research directors in the food, beverage, cosmetics, and other consumer products industries of all sizes. Emphasizes the importance of scientific sensory methodology used to measure and understand consumer perception Illustrates the importance of planning, managing and communicating product sensory information in a way that is actionable to developers, marketers and legal counsel Presents how sensory science is becoming more influential at the front end of innovation Discusses measurement, the design of experiments, and how to understand key sensory drivers that most influence consumers Explores the global nature of products and how companies can benefit by having fundamental training programs in sensory and consumer science Contains demonstrated methods for test selection, application and measurement, and testing with the right consumer, including more typical usage environments Includes worked examples for interpreting and displaying results Features a new chapter on how to get your research published

A popular book in its first edition, The Food Chemistry Laboratory: A Manual for Experimental Foods, Dietetics, and Food Scientists, Second Edition continues to provide students with practical knowledge of the fundamentals of designing, executing, and reporting the results of a research project. Presenting experiments that can be completed, in many cases, without requiring extensive student laboratory facilities, the authors include new exercises in the areas of physical properties, lipids, proteins, and gelatin. Also new in this edition are a brief introduction to each laboratory exercise and a listing of materials needed, approximate time needed for completion, and possible complications and/or pitfalls. Tested and refined for over 20 years, and performed by thousands of students, experiments are presented within 12 planned laboratory sessions. This flexible format allows you to create your own laboratory sessions by choosing the number and order of sessions and experiments to be performed. In addition to the well-tested experiments, The Food Chemistry Laboratory, Second Edition provides students with information on accessing food chemistry literature, research proposal preparation, preparing oral and written technical reports, and an evaluation score sheet. Guidelines for preparing laboratory notebooks are also included and a handy appendix allows rapid access to directions for setting up a difference testing experiment.

Manual describing the factors influencing sensory measurements; physical facilities needed; sample preparation; selection and training of panellists; experimental design; statistical tests; sensory analysis test methods; discriminative tests, descriptive tests, affective tests, and the production of a sensory analysis report.

This second edition laboratory manual was written to accompany Food Analysis, Fourth Edition, ISBN 978-1-4419-1477-4, by the same author. The 21 laboratory exercises in the manual cover 20 of the 32 chapters in the textbook. Many of the laboratory exercises have multiple sections to cover several methods of analysis for a particular food component of characteristic. Most of the laboratory exercises include the following: introduction, reading assignment, objective, principle of method, chemicals, reagents, precautions and waste disposal, supplies, equipment, procedure, data and calculations, questions, and references. This laboratory manual is ideal for the laboratory portion of undergraduate courses in food analysis.

The quality and safety of the food we eat deserves the utmost attention and is a priority for producers and consumers alike. Shelf life studies provide important information to manufacturers and consumers to ensure a high-quality food product. Various evaluation methods are used for shelf life determination and they are usually performed at the manufacturer level. Moreover, various techniques are utilized throughout the food chain that enhance the shelf life of food products. This sensitive issue is reviewed in Shelf Life and Food Safety, which brings together a group of subject experts to present up-to-date and objective discussions on a broad range of topics including food spoilage and safe preservation, packaging, and sensory aspects. The book presents both traditional and innovative technologies for enhancing food safety and increasing shelf life, along with methods for the assessment and prediction of food safety and shelf life. Key Features Overviews the issues associated with shelf life enhancement and shelf life evaluation of various food products Addresses issues important to maintaining food safety Explains how shelf life depends on factors, including ingredients for formulation, processing techniques, packaging, and storage conditions Covers shelf life evaluation methods, determinants for shelf life, food quality assessment, and basic and innovative technologies that will improve the shelf life of food products This book is the first of its kind focusing on issues related to evaluation techniques for shelf life determinants, and techniques for shelf life enhancement. It is appropriate for students, researchers, scientists, and professionals in food science and technology. It is also a helpful source of information for people involved in the food industry, food processing sector, product development, marketing, and other associated fields.

Evaluation Technologies for Food Quality summarizes food quality evaluation technologies, which include sensory evaluation techniques and chemical and physical analysis. In particular, the book introduces many novel micro and nano evaluation techniques, such as atomic force microscopy, scanning electron microscopy, and other nanomaterial-based methods. All topics cover basic principles, procedures, advantages, limitations, recent technology development, and application progress in different types of foods. This book is a valuable resource for scientists in the field of food science, engineering, and professionals in the food industry, as well as for undergraduate and postgraduate students studying food quality evaluation technology. Explains basic principles, procedures, advantages, limitations, and current applications of recent food quality technologies Provides guidance on the understanding and application of food quality evaluation technology in the field of food research and food industry Introduces many novel micro/nano evaluation techniques, such as atomic force and scanning electron microscopies and other nanomaterial-based methods
