Food Protein Based Colloids Structure Digestion And Nutrients Delivery

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.

Food Colloids: Interactions, Microstructure and Processing describes the principles and practice underlying the formulation of food emulsions, dispersions, gels, and foams. Emphasis is on understanding how the functional properties of biopolymers and surfactants determine the texture and shelf-life of multiphase food materials. This book provides essential new findings by experts in the field on specific topics including: the interfacial rheological properties of proteins; the use of microscopy and image analysis to probe structure and phase transitions; the control of colloidal stability during thermal and mechanical processing; the interactions of proteins with polysaccharides and emulsifiers; the incorporation of neutraceuticals into food colloids; and the consumer perception of taste and texture. Food Colloids: Interactions, Microstructure and Processing provides a link between current research on the fundamental physical chemistry of colloidal systems and the requirements of the food technologist to use modern colloid science in new product formulation. It is suitable for postgraduates and researchers, both in industry and academia.

Food structure at the molecular level and how it impacts on health, taste, texture and shelf life is becoming an increasingly important area of science. Food Colloids: Self-Assembly and Material Science describes new developments in the theory and practice of the formulation of food emulsions, dispersions, gels and foams. Particular emphasis is placed on the self-assembly of surfactants and biopolymers in food. Topics include: colloid science in food nutrition and the relationship of texture to sensory perception of food materials. It also discusses the exploitation of surfactant mesophases for nanoscale encapsulation, the interfacial rheological properties of mixed interfaces, the dynamics and microrheology of gels and emulsions, the stability of droplets and bubbles, the effects of thermal and mechanical processing on food colloid stability and the electrostatic interactions of proteins with polysaccharides. This authoritative book will serve as a guide and reference to researchers in the field of food colloids.

Food Colloids: Fundamentals of Formulation describes the physico-chemical principles underlying the formulation of multi-component, multi-phase food systems. Emphasis is placed on the interfacial properties of proteins and the role of protein interactions in determining the properties of emulsions, dispersions, gels and foams. The coverage includes authoritative overviews of conceptual issues as well as descriptions of new experimental techniques and recent food colloids research findings. Specific topics include atomic force microscopy, aggregation phenomena, coalescence mechanisms, crystallization processes, surface rheology, protein-lipid interactions and mixed biopolymer systems. This book provides essential new material for those active in the field and is suitable for postgraduates and researchers, both in industry and academia.

Some New Aspects of Colloidal Systems in Foods is a new book on food emulsions, which provides in-depth coverage of some new aspects of food colloids. The coverage includes confident overviews of theoretical issues as well as descriptions of new techniques and recent colloid research findings. Specific topics include the role of electrostatic and steric forces in the stabilization of food colloids, antioxidants in food emulsions, nanoemulsions, and nanostructured colloids in food science. This book can be used as a specialized text for graduate students and researchers in food science and technology. In addition, it will serve as a reference text for advanced students in chemistry, engineers, biochemists, nutritionists, and analytical chemists in the food industry and research.

Food scientists aim to control the taste and texture of existing food products and to formulate new structures of high quality using novel combinations of ingredients and processing methods. Food Colloids, Biopolymers and Materials describes the physical chemistry and material science underlying the formulation and behaviour of multi-phase food systems and includes: * descriptions of new experimental techniques * recent food colloids research findings * authoritative overviews of conceptual issues Essential new findings are presented and emphasis is placed on the interfacial and gelation properties of food proteins, and the role of colloidal and biopolymer interactions in determining the properties of emulsions, dispersions, gels and foams. Specific topics include: confocal microscopy; diffusing wave spectroscopy; protein-polysaccharide interactions; biopolymer phase separation; fat crystallization; bubble/droplet coalescence; and bulk and surface rheology. This book is the latest addition to the highly regarded food colloid series published by the Royal Society of Chemistry and is of relevance to those working and researching in food science and surface and colloid science.

For the first time, this singular and comprehensive text presents a focus on quantitative studies aiming to describe food digestion and the tools that are available for quantification. A case study relevant to real-world applications places this theoretical knowledge in context and demonstrates the different ways digestion studies can be used to develop food products. Interdisciplinary Approaches to Food Digestion undertakes a multidisciplinary approach to food digestion studies, placing them in context and presenting relevant phenomena plus the challenges and limitations of different approaches. This book presents a unique, useful reference work to scientists, students, and researchers in the area of food science, engineering, and nutrition. Over the last two decades there has been an increasing demand for foods that deliver specific nutritional values. In addition, the dramatic increase of food related diseases such as obesity requires the development of novel food products that control satiety and glycemic response. Overall, digestion studies are gaining increasing attention in recent years, especially as the link between diet and health/well-being becomes more evident. However, digestion is a complex process involving a wide range of disciplines such as medicine, nutrition, chemistry, materials science, and engineering. While a significant body of work exists within each discipline, there is a lack of a multidisciplinary approach on the topic which will provide a holistic view of the process. With Interdisciplinary Approaches to Food Digestion, researchers are finally presented with this much needed approach.

Focusing on the complexity of the food digestion process from oral cavity to intestine, this book looks at the digestive system, techniques used to study food digestibility, the glycemic index and bioavailability of food components for readers from the field of medicine, food scientists, nutritionists and food physicists.

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.
