The field of food colloids is concerned with the physical chemistry of food systems viewed as assemblies of particles and macromolecules in various stages of supramolecular and microscopic organization. Butter, cheese, ice cream, margarine mayonnaise and yogurt are all examples of food colloids. This book describes experimental and theoretical developments in the field over the past 10-15 years. The authors have tried to strike a reasonable balance between theory and experiment, between principles and applications, and between molecular and physical approaches to the subject.
The field of food colloids is concerned with the physical chemistry of food systems viewed as assemblies of particles and macromolecules in various states of supramolecular and microscopic organization. The objective is to relate the equilibrium and dynamic properties of the system to the inter actions amongst the constituent molecular and particulate entities. The emphasis is on structure and kinetics at the colloidal scale, and with the distribution of molecular food components (proteins, lipids, poly saccharides, etc.) between dispersed and continuous bulk phases (water, fat, air, etc.) and various kinds of interfaces (oil-water, air-water, etc.). Food products such as butter, cheese, ice-cream, margarine, mayonnaise of food colloids. and yoghurt are all examples This book describes some recent experimental and theoretical develop ments in the field of food colloids. By way of background, we start with a brief survey of the current consumer trends which may point the way towards future research opportunities in the field. Chapter 1 also attempts to illustrate the way in which advances in instrumental methods and experimental investigations of well-defined mixed protein-surfactant systems are offering new insights into the structure of protein adsorbed layers and the competitive adsorption of proteins in oil-in-water emulsion systems.
The field of food colloids is concerned with the structural and dynamic aspects of multi-phase food systems - dispersions, emulsions, foams, gels - viewed from a physical chemistry perspective as assemblies of molecules and particles in various states of organisation. The main molecular components of food colloids are proteins, lipids and polysaccharides. The primary objective of the field is to relate the structural, stability and rheological properties of such systems to the interactions between constituent components and to their distribution between the bulk phases and various kinds of interfaces. This volume records most of the lecture programme at the international conference on "Food Colloids - Proteins, Lipids and Polysaccharides" held in Sweden on 24-26th April 1996.
Manufactured foodstuffs typically exist in the form of complex, multi-phase, multi-component, colloidal systems. One way to try to make sense of their chemical and structural complexity is to study simple model systems in which the nature and properties of the polymer molecules and dispersed particles are relatively well known. This volume consists of a collection of papers delivered at a conference on food colloids, the main theme of which was the role of food macromolecules in determining the stability, structure, texture and rheology of food colloids, with particular reference to gelling behaviour and interactions between macromolecules and interfaces. A feature of the collection is the wide range of physico-chemical techniques now being used to address problems in this field.
Advances in Food Rheology and Its Applications presents the latest advances in the measurement and application of food rheology, one of the most important tools for food companies when characterizing ingredients and final products, and a predictor of product performance and consumer acceptance. Split into two main focuses, the book gives in-depth analysis of the general advances in the field, with coverage of the relationship between food microstructure and rheology, the use of tribology in the study of oral processing, the use of large amplitude oscillatory shear (LAOS) measurement and Fourier-transform rheology in food, and the influence of fibers and particle size distribution on food rheology, as well as many other advances. Written by a leading international team of authors, the book provides an in-depth and state-of-the-art coverage of this essential topic on the consumer acceptance of food. - Brings together top researchers in the field of rheology, providing in-depth and state-of-the-art coverage on an area of study essential for managing the quality of foods and gaining consumer acceptance - Presents in-depth coverage of advances in rheology, many of which have never been featured before, including tribology, large amplitude oscillatory shear measurement, and the influence of fibers and particle size distribution on food rheology - Contains information that is highly relevant to the industrialist who wants to improve the rheological properties of the foods with which they are working
Still the most up-to-date, comprehensive, and authoritative book on food diagnostics available Featuring seven entirely new chapters, the second edition of this critically acclaimed guide has been extensively revised and updated. Once again delivering food professionals the latest advances in food diagnostics and analysis, the book approaches the topic in several different ways: reviewing novel technologies to evaluate fresh products; describing and analysing in depth specific modern diagnostics; providing analyses of data processing; and discussing global marketing, with insights into future trends. Written by an international team of experts, this volume not only covers most conventional lab-based analytical methods, but also focuses on leading-edge technologies which are being or are about to be introduced. Advances in Food Diagnostics, Second Edition: Covers ultrasound, RMN, chromatography, electronic noses, immunology, GMO detection and microbiological and molecular methodologies for rapid detection of pathogens Explores the principles and applications of immunodiagnostics in food safety and the use of molecular biology to detect and characterize foodborne pathogens Includes DNA-based and protein-based technologies to detect and identify genetically-modified food or food components Focuses on the translation of diagnostics tests from bench to the market in order to illustrate the benefits to the food industry Provides an overview of the business end of food diagnostics; identifying the markets, delineating the sellers and the buyers, comparing current technology with traditional methods, certifying operations and procedures, and analysing diagnostic devices within the food and related industries This is an indispensable resource for food scientists, food quality analysts, food microbiologists and food safety professionals. It also belongs on the reference shelves of labs conducting food diagnostics for the analysis of the sensory, quality and safety aspects of food.
Understanding the biochemistry of food is basic to all other research and development in the fields of food science, technology, and nutrition, and the past decade has seen accelerated progress in these areas. Advances in Food Biochemistry provides a unified exploration of foods from a biochemical perspective. Featuring illustrations to elucidate m
This book presents a comprehensive overview of the freezing of colloidal suspensions and explores cutting-edge research in the field. It is the first book to deal with this phenomenon from a multidisciplinary perspective, and examines the various occurrences, their technological uses, the fundamental phenomena, and the different modeling approaches. Its chapters integrate input from fields as diverse as materials science, physics, biology, mathematics, geophysics, and food science, and therefore provide an excellent point of departure for anyone interested in the topic. The main content is supplemented by a wealth of figures and illustrations to elucidate the concepts presented, and includes a final chapter providing advice for those starting out in the field. As such, the book provides an invaluable resource for materials scientists, physicists, biologists, and mathematicians, and will also benefit food engineers, civil engineers, and materials processing professionals.
