Food Science and Technology: A Series of Monographs: Food Texture and Viscosity: Concept and Measurement focuses on the texture and viscosity of food and how these properties are measured. The publication first elaborates on texture, viscosity, and food, body-texture interactions, and principles of objective texture measurement. Topics include area and volume measuring instruments, chemical analysis, multiple variable instruments, soothing effect of mastication, reasons for masticating food, rheology and texture, and the rate of compression between the teeth. The book then examines the practice of objective texture measurement and viscosity and consistency, including the general equation for viscosity, methods for measuring viscosity, factors affecting viscosity, tensile testers, distance measuring measurements, and shear testing. The manuscript takes a look at the selection of a suitable test procedure and sensory methods of texture and viscosity measurement. Discussions focus on nonoral methods of sensory measurement; correlations between subjective and objective measurements; variations on the texture profile technique; and importance of sensory evaluation. The publication is a vital source of information for food experts and researchers interested in food texture and viscosity.

Drawing together literature from a myriad of sources, this book focuses on the texture and viscosity of food as well as the techniques for measuring these properties. Food Texture and Viscosity: Concept and Measurement includes a brief history of the field and its basic principles and then goes on to provide a detailed discussion of the physical interactions between the human body and food, objective methods of texture measurements, commercially available instruments and their uses, various types of viscous flow, and sensory methods for measuring texture and viscosity. An appendix lists names and addresses of suppliers for anyone interested in purchasing equipment. Incorporating material from numerous sources across a wide range of disciplines, this book will prove valuable to students, faculty, researchers, and anyone working in food technology and sensory evaluation.

The concept behind this book is to take a holistic view of food texture, starting with the determination of food texture, its perception in the mouth, and its measurement by both sensory and instrumental methods, and to examine the relation between those methods. The book has been divided into two sections. The first deals with perception of food texture and techniques for its measurement. The second focuses on individual groups of food commodities. The first section is interlaced with appropriate food-related examples to reinforce the applied nature of the subject.

A complete guide to the textural characteristics of an international array of traditional and special foods It is widely recognized that texture has an intrinsic relationship to food preference. A full understanding of its functions and qualities is, therefore, of crucial importance to food technologists and product developers, as well as those working towards the treatment of dysphagia. Textural Characteristics of World Foods is the first book to apply a detailed set of criteria and characteristics to the textures of traditional and popular foods from across the globe. Structuring chapters by region, its authors chart a journey through the textural landscapes of each continent’s cuisines, exploring the complex and symbiotic relationships that exist between texture, aroma, and taste. This innovative text: Provides an overview of the textural characteristics of a wide range of foods Includes descriptions of textures and key points of flavor release Examines the relationships between the texture, taste, and aroma of each food presented Is structured by geographic region Rich with essential insights and important research, Textural Characteristics of World Foods offers all those working in food science and development a better picture of texture and the multifaceted role it can play.

This volume provides an overview of the latest research findings on the physics, physiology, and psychology of food oral consumption, as well as the experimental techniques available for food oral studies. Coverage includes the main physical and physiological functionalities of the mouth; the location and functionalities of various oral receptors; the main sequences of eating and drinking, and the concomitant food disintegration and destabilisation. Chapters also explain oral processing and its relation to flavour release and texture perception, and there is an introduction to the principles of food rheology as they relate to eating. Food Oral Processing is directed at food scientists and technologists in industry and academia, especially those involved in sensory science and new product development. It will also be of interest to oral physiologists, oral biologists and dentists. The book will be a useful reference for undergraduate and postgraduate students of these disciplines.

Cereal chemists are interested in rheology because the dough undergoes some type of deformation in every phase of the conversion of flour into baked products. During mixing, dough is subjected to extreme deformations, many that exceed the rupture limit; during fermentation, the deformations are much smaller and therefore exhibit a different set of rheological properties; during sheeting and molding, deformations are at an intermediate level; and, finally, during proofing and baking, the dough is subjected to a range of deformations at varying temperatures. Accordingly, the application of rheological concepts to explain the behavior of dough seems a natural requirement of research on the interrelationships among flour constituents, added ingredients, process parameters, and the required characteristics of the final baked product. At any moment in the baking process, the rheological behavior, that is, the nature of the deformation, exhibited by a specific dough derives from the applied stress and how long the stress is maintained. The resulting deformation may be simple, such as pure viscous flow or elastic deformation, and therefore easy to define precisely. Moreover, under some conditions of stress and time (i. e. , shear rate), doughs behave as ideal materials and their behavior follows theory derived from fundamental concepts. Under usual conditions encountered in baking, however, the rheological behavior is far from ideal; shear rates vary widely and sample size and dimensions are ill-defined.

Abstract: A novel reference text for food scientists and technologists, nutritionists, analytical chemists, and microbiologists concerned with sensory evaluation provides a broad overview of food texture measurement that covers both subjective (sensory evaluation) and objective (instrumental analysis) aspects of food texture asessments. Included are discussions and information concerning rheology and microstructure analysis, psychophysics, and product testing and product optimization. Numerous illustrations, graphs, and tables are presented throughout the text, and literature citations are appended to each of the 12 text chapters. Each of the chapters was prepared by experts in their respective areas of study.

The first edition of Food processing technology was quickly adopted as the standard text by many food science and technology courses. This completely revised and updated third edition consolidates the position of this textbook as the best single-volume introduction to food manufacturing technologies available. This edition has been updated and extended to include the many developments that have taken place since the second edition was published. In particular, advances in microprocessor control of equipment, 'minimal' processing technologies, functional foods, developments in 'active' or 'intelligent' packaging, and storage and distribution logistics are described. Technologies that relate to cost savings, environmental improvement or enhanced product quality are highlighted. Additionally, sections in each chapter on the impact of processing on food-borne micro-organisms are included for the first time. - Introduces a range of processing techniques that are used in food manufacturing - Explains the key principles of each process, including the equipment used and the effects of processing on micro-organisms that contaminate foods - Describes post-processing operations, including packaging and distribution logistics

The theme for this volume was chosen because no previous book has discussed the quality attributes of meat, poultry and fish and the methods that can be utilized for their measurement. The topics are not only timely but of great importance. Chapter I provides an introduction to the topic and presents a brief overview of the subject to be discussed. The next two chapters review information on the importance of color and some color problems in muscle foods, and explains the basis of color vision and perception of color before describing the methods that may be used for its measure ment. The following chapter discusses water binding and juiciness and their importance, while Chapter 5 provides the first intensive modern review on measurement of juiciness that has been published (to the knowledge of the author and editors). Chapter 6 reviews the physiology and psychology of flavor and aroma, which serves as a background for further discussion on the flavor and aroma of foods. The next chapter discusses the chemistry of flavor and aroma in muscle foods, while measurement of flavor and aroma are covered in Chapter 8. Chapter 9 reviews the species-specific meat flavors and aromas. Chapter 10 reviews some flavor and aroma problems in muscle foods and their measurement.
