Physical Chemistry Of Food Processes Volume I Fundamental Aspects

Volume 1 of a 2 volume set, this book introduces the microscopic and electrical properties and the basic rheological aspects of food dispersions. Elements of thermodynamics and quantum mechanics are presented, with examples relevant to molecular processes and chemical bonding. The hydration of proteins and starches, water sorption isotherms, extrusion cooking of starches and foods, and the chemical structures of water, carbohydrates, proteins, and nucleic acids are covered.

Exploring the structure and physical and chemical properties of solutions, dispersions, soft solids, fats, and cellular systems, Physical Chemistry of Foods describes the physiochemical principles of the reactions and conversions that occur during the manufacture, handling, and storage of foods. Coverage progresses from aspects of thermodynamics, bonds and interaction forces, and reaction kinetics, to transport phenomena, polymers, colloidal interactions, nucleation, glass transitions and freezing, and soft solids. This comprehensive volume effectively clarifies the physicochemical processes encountered in food product development.

In the 21st Century, processing food is no longer a simple or straightforward matter. Ongoing advances in manufacturing have placed new demands on the design and methodology of food processes. A highly interdisciplinary science, food process design draws upon the principles of chemical and mechanical engineering, microbiology, chemistry, nutrition and economics, and is of central importance to the food industry. Process design is the core of food engineering, and is concerned at its root with taking new concepts in food design and developing them through production and eventual consumption. Handbook of Food Process Design is a major new 2-volume work aimed at food engineers and the wider food industry. Comprising 46 original chapters written by a host of leading international food scientists, engineers, academics and systems specialists, the book has been developed to be the most comprehensive guide to food process design ever published. Starting from first principles, the book provides a complete account of food process designs, including heating and cooling, pasteurization, sterilization, refrigeration, drying, crystallization, extrusion, and separation. Mechanical operations including mixing, agitation, size reduction, extraction and leaching processes are fully documented. Novel process designs such as irradiation, high-pressure processing, ultrasound, ohmic heating and pulsed UV-light are also presented. Food packaging processes are considered, and chapters on food quality, safety and commercial imperatives portray the role process design in the broader context of food production and consumption.

Food Engineering is a component of Encyclopedia of Food and Agricultural Sciences, Engineering and Technology Resources in the global Encyclopedia of Life Support Systems (EOLSS), which is an integrated compendium of twenty one Encyclopedias. Food Engineering became an academic discipline in the 1950s. Today it is a professional and scientific multidisciplinary field related to food manufacturing and the practical applications of food science. These volumes cover five main topics: Engineering Properties of Foods; Thermodynamics in Food Engineering; Food Rheology and Texture; Food Process Engineering; Food Plant Design, which are then expanded into multiple subtopics, each as a chapter. These four volumes are aimed at the following five major target audiences: University and College students Educators, Professional practitioners, Research personnel and Policy analysts, managers, and decision makers and NGOs

This book provides a fundamental understanding of physical properties of foods. It is the first textbook in this area and combines engineering concepts and physical chemistry. Basic definitions and principles of physical properties are discussed as well as the importance of physical properties in the food industry and measurement methods. In addition, recent studies in physical properties are summarized. The material presented is helpful for students to understand the relationship between physical and functional properties of raw, semi-finished, and processed food in order to obtain products with desired shelf-life and quality.

Food processing is now the biggest industry in the UK and in many other countries. It is also rapidly changing from what was essentially a craft industry, batch processing relatively small amounts of product, to a very highly automated one with continuously operating high speed production lines. In addition, consumers have developed a greater expectation for consistently high standard products and coupled this with demands for such things as a more natural flavour, lower fat etc. The need for an increased knowledge of the scientific principles behind food processing has never been greater. Within the industry itself, increased automation, company diversification and amalgamations etc. have meant that those working in it have often to change their field of operation. Whereas twenty years ago, someone starting work in one branch of the food industry could expect, if he or she so desired, to work there all their working lives, this is now seldom the case. This means that a basic knowledge of the principles behind food processing is necessary both for the student at university or college, and for those already in the industry. It is hoped, therefore, that this book will appeal to both, and prove to be a useful reference over a wide range of food processing.

This resource provides effective mechanistic methods for analyzing and understanding physical and chemical behaviour in foods, and explains how to manipulate and control such behaviour during food processing, distribution and use.;Written by 23 authorities in the field, Physical Chemistry of Foods: treats factors controlling crystallization, cross-linking reactions, dispersion and surface-adsorption processes in foods and clarifies how to modify crystal size distribution, stabilize dispersions and minimize fouling; explores uptake competition between mineral nutrients - offering guidelines for efficient uptake and absorption; describes kinetic rate-controlling steps in Maillard reactions - examining how to manipulate Maillard browning; discusses how gels form and instrumental methods of following gelling processes and covers how to create gel-based textures and structures in foods; considers factors that control the behaviour of bread during dough development, proofing, and baking - showing how carbon dioxide release affects loaf expansion; and reveals how glass transitions affect rheological and kinetic behaviour and transport processes in foods - detailing how to manipulate glass transitions and product behaviour by changes in composition and water content.;Food scientists and technologists; food, agricultural and bioresource engineers; physical and surface chemists; nutritionists; and upper-level undergraduate and graduate students and industrial trainees in these disciplines will repeatedly find valuable new insights and approaches for dealing with practical and theoretical problems and a wealth of useful information in Physical Chemistry of Foods, with its more than 1380 literature citations.
