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.

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.

This selection of key presentations from the Food Structures, Digestion and Health conference is devoted to the unique and challenging interface between food science and nutrition, and brings together scientists across several disciplines to address cutting-edge research issues. Topics include modeling of the gastrointestinal tract, effect of structures on digestion, and design for healthy foods. New knowledge in this area is vital to enable the international food industry to design of a new generation of foods with enhanced health and sensory attributes. The multidisciplinary approach includes research findings by internationally renowned scientists, and presents new research findings important and pertinent to professionals in both the food science and nutrition fields.

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.

Nutrient Delivery: Nanotechnology in the Agri-Food Industry, Volume Five, discusses the fabrication, merits, demerits, applications, and bioavailability enhancement mechanisms of various nanodelivery systems. Recent developments in various nanodelivery systems are also highlighted. Volume 5 contains twenty chapters, prepared by outstanding international researchers from Argentina, Brazil, Canada, China, Croatia, India, Iran, Ireland, México, Pakistan, Portugal, Serbia, Sri Lanka, and the United States. In recent years, the delivery of micronutrients at nanoscale has been widely studied as these systems have the potential to improve bioavailability, enable controlled release and enhance stability of food bioactives to a greater extent. The nanodelivery systems typically consist of the food bioactive compound encapsulated and stabilized in food grade ingredients such as lipids, proteins or polysaccharides with diameters ranging from 10 nm to 1000 nm. Among these, the lipid based delivery systems such as nanoemulsions, solid lipid nanoparticles, nanoliposomes and micelles are widely studied for the delivery of lipophilic bioactive compounds. These delivery vehicles improve the solubility, permeability, stability and bioavailability of the lipophilic compounds thereby enhancing their potential for oral delivery and functional food development. On the other hand, the hydrophilic bioactives are delivered through protein, polysaccharide or biopolymer based colloidal nanosystems such as hydrogels, nanogels and polymer nanoparticles. The major concern other than solubility is the intestinal permeability of the micronutrients. For instance, the delivery system for compounds with poor intestinal permeability and low solubility need to be carefully designed using suitable lipids and surfactants. Offers updated material for undergraduate and postgraduate students in food science, biotechnology, and related engineering fields Provides a valuable resource of recent scientific progress, along with most known applications of nanomaterials in the food industry for researchers, engineers, and academics Includes novel opportunities and ideas for developing or improving technologies in the food industry

The breakdown of food structures in the gastrointestinal tract has a major impact on the sensory properties and nutritional quality of foods. Advances in understanding the relationship between food structure and the breakdown, digestion and transport of food components within the GI tract facilitate the successful design of health-promoting foods. This important collection reviews key issues in these areas. Opening chapters in Part one examine oral physiology and gut microbial ecology. Subsequent chapters focus on the digestion, absorption and physiological effects of significant food components, such as lipids, proteins and vitamins. Part two then reviews advances in methods to study food sensory perception, digestion and absorption, including in vitro simulation of the stomach and intestines and the use of stable isotopes to determine mineral bioavailability. The implications for the design of functional foods are considered in Part three. Controlling lipid bioavailability using emulsion-based delivery systems, designing foods to induce satiation and self-assembling structures in the GI tract are among the topics covered. With contributions from leading figures in industry and academia, Designing functional foods provides those developing health-promoting products with a broad overview of the wealth of current knowledge in this area and its present and future applications. Reviews digestion and absorption of food components including oral physiology and gut microbial ecology Evaluates advances in methods to study food sensory perception assessing criteria such as simulation of flavour released from foods Investigates the implications for the design of functional foods including optimising the flavour of low-fat foods and controlling the release of glucose
