Available in PDF, EPUB and Kindle. Book excerpt: Rheology is fundamentally important in food manufacturing in two major senses. Understanding the way in which a substance moves and behaves is essential in order to be able to transport and mix it during processing. Secondly, the rheology of a product dictates much of the consumer experience, e.g. in relation to texture and mouthfeel. This book doesn’t overwhelm the reader with complex mathematical equations but takes a simple and practically-focused approach, interpreting the implications of rheological data for use in different food systems. Through this approach industry-based food developers / rheologists, students, and academics are given clear, concise interpretation of rheological data which directly relates to actual perceived functionality in the food. The functionality may relate to texture, structure and mouthfeel, and may result as a function of temperature, pH, flocculation, concentration effects, and mixing. The interpretative view is based on the principle that the food rheologist will produce a graph, for example of viscosity or gelation profiling, and then have to extract a practical meaning from it. For example, if viscosity falls with time as a function of pH, this knowledge can be used to tell the customer that the viscosity can be followed with just a pH meter and a stopwatch. Rheological measurements have shown that once the pH has dropped 1 unit after 10 minutes, the viscosity has been halved. This is the type of practical and valuable information for customers of the industrial food rheologist which the book will enable readers to access. Key features: A uniquely practical approach to the often difficult science of food rheology Includes chapters introducing the basics of food rheology before moving on to how data can be usefully and easily interpreted by the food scientist Can be used as a teaching aid on academic or industry-based courses

Download or read book Food Texture and Viscosity: Concept and Measurement written by Malcolm C. Bourne and published by Elsevier. This book was released on 2014-06-28 with total page 340 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Rheology Essentials of Cosmetic and Food Emulsions written by Rüdiger Brummer and published by Springer Science & Business Media. This book was released on 2006-05-27 with total page 191 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cosmetic emulsions exist today in many forms for a wide variety of applications, including face and hand creams for normal, dry or oily skin, body milks and lotions, as well as sun-block products. Keeping track of them and their properties is not always easy despite informative product names or partial names (e.g. hand or face cream) that clearly indicate their use and properties. This practical manual provides a detailed overview that describes the key properties and explains how to measure them using modern techniques. Written by an expert in flows and flow properties, it focuses on the application of rheological (flow) measurements to cosmetic and food emulsions and the correlation of these results with findings from other tests. Beginning with a brief history of rheology and some fundamental principles, the manual describes in detail the use of modern viscometers and rheometers, including concise explanations of the different available instruments. But the focus remains on practical everyday lab procedures: how to characterize cosmetic and food emulsions with different rheological tests such as temperature, time, stress and strain, both static and dynamic. Also the critical topic of how the results correlate with other important product characteristics, for instance, skin sensation, pumping performance, stability etc. is carefully explored. Many pictures, illustrations, graphs and tables help readers new to the measurement of cosmetic emulsions in their daily work as well as to the more experienced who seek additional special tips and tricks.

Download or read book Rheology written by Geoffrey Mitchell and published by Nova Science Publishers. This book was released on 2014 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rheology is the study of the flow of matter, primarily in the liquid state, but also as 'soft solids' or solids under flow conditions in which they respond with plastic flow rather than deforming elastically in response to the applied force. An understanding of the flow of matter underpins a diversity of technologies and industrial processing including polymer and food processing. It applies to substances which have a complex microstructure, such as concentrated solutions, suspensions, polymers and inorganic glass formers as well as biological materials which belong to the class of soft matter. Rheological measurements are seemingly straightforward to make, but require models to interpret the mechanical measurements in terms of the microscopic behaviour of the material. This boo draws these diverse strands of current rheological research in to a single volume which embraces theory, measurement and applications in topics as diverse as theory and electrospinning, coal ash slag and food processing, hydrogels and liquid crystal polymers, reaction injection moulding and microreheology.There is a strong focus on the emerging topics in rheology and its application to complex soft matter especially in the field of food science and technology. The sixteen chapters in the volume present unpublished research work across these topics from leading authorities in the relevant field. The volume has a strong international representation with the selected authors drawn from some ten countries in Europe, South America and the rest of the world. Each chapter contains a comprehensive bibliography of related work. The book provides a fascinating snap shot across the current developments in rheology.
