Hydrocolloids

Hydrocolloids are among the most widely used ingredients in the food industry. They function as thickening and gelling agents, texturizers, stabilisers and emulsifiers and in addition have application in areas such as edible coatings and flavour release. Products reformulated for fat reduction are particularly dependent on hydrocolloids for satisfactory sensory quality. They now also find increasing applications in the health area as dietary fibre of low calorific value. The first edition of Handbook of Hydrocolloids provided professionals in the food industry with relevant practical information about the range of hydrocolloid ingredients readily and at the same time authoritatively. It was exceptionally well received and has subsequently been used as the substantive reference on these food ingredients. Extensively revised and expanded and containing eight new chapters, this major new edition strengthens that reputation. Edited by two leading international authorities in the field, the second edition reviews over twenty-five hydrocolloids, covering structure and properties, processing, functionality, applications and regulatory status. Since there is now greater emphasis on the protein hydrocolloids, new chapters on vegetable proteins and egg protein have been added. Coverage of microbial polysaccharides has also been increased and the developing role of the exudate gums recognised, with a new chapter on Gum Ghatti. Protein-polysaccharide complexes are finding increased application in food products and a new chapter on this topic as been added. Two additional chapters reviewing the role of hydrocolloids in emulsification and their role as dietary fibre and subsequent health benefits are also included. The second edition of Handbook of hydrocolloids is an essential reference for post-graduate students, research scientists and food manufacturers. Extensively revised and expanded second edition edited by two leading international authorities Provides an introduction to food hydrocolliods considering regulatory aspects and thickening characteristics Comprehensively examines the manufacture, structure, function and applications of over twenty five hydrocolloids

About 70 papers from an international conference in Tsukuba, Japan, in November 1992, discuss the various hydrocolloids that are widely used to control the viscoelasticity, emulsification, gelation, dispersion, thickening, and other textural qualities of food products. They consider the recent devel

First Published in 1982, this three-volume set explores the value of hydrocolloids in food. Carefully compiled and filled with a vast repertoire of notes, diagrams, and references this book serves as a useful reference for dieticians and other practitioners in their respective fields.

In Hydrocolloids in Food Processing, a group of the most experienced and impartial experts explains what stabilizers should be used and how they should be used, food product by food product. Numerous actual product formulations are packed into each chapter and the processing procedures to make these formulations are clearly described. Food manufacturers are shown how to accurately use food stabilizers to make the highest quality food products. Coverage includes all the practical details needed to ensure the most accurate QA standards and testing procedures for each hydrocolloid. Finally, Hydrocolloids in Food Processing explains how to navigate the often tricky area of dealing with hydrocolloid suppliers. An informative discussion of how hydrocolloid companies think and operate today is followed by precise strategies to ensure that the most mutually beneficial relationships can be obtained between specific customer types and appropriate types of suppliers.

The first guide devoted to the functions, structures, and applications of natural hydrocolloids In today’s health-conscious climate, the demand for natural food products is growing all the time. Natural hydrocolloids, therefore, have never been more popular. With their thickening, stabilizing, gelling, fat replacing, and binding qualities, these naturally occurring, plant-based polymers can fulfil many of the same functions as commercial ingredients like xanthan, guar, gum Arabic, pectin, and starch. Moreover, certain health benefits have been linked with their often biological active compounds and high-fiber compositions, including potential prebiotic effects and the reduction of blood cholesterol levels. Application of these novel hydrocolloids is, however, still underexplored. Emerging Natural Hydrocolloids aims to remedy this by providing a thorough overview of their structure–function relationships, rheological aspects, and potential utility in mainly the food and pharmaceutical industries. This accessible, quick-reference guide features: A comprehensive and up-to-date survey of the most significant research currently available on natural hydrocolloids Examinations of the major functions and rheological aspects of novel hydrocolloids Information on the potential applications of biopolymers within both foods and pharmaceutical systems Collaborations from an international team of food scientists Emerging Natural Hydrocolloids: Rheology and Functions offers scientists, engineers, technologists, and researchers alike a unique and in-depth account of the uncharted world of novel hydrocolloids, their uses, properties, and potential benefits.

Handbook of Hydrocolloids, Third Edition is a must-have substantive reference on hydrocolloids, helping food industry scientists ever since its first edition was published and well received. This thoroughly updated and expanded edition reviews the structure, function, properties, and applications of a broad range of hydrocolloids used in food and related industries. The third edition updates existing chapters on developments and theories on the structure and functional characteristics of individual hydrocolloids. The book provides additional chapters on new techniques for the chemical and physicochemical characterization of hydrocolloids, and applications technologies for encapsulation and controlled release of active compounds. Edited by two leading international authorities in the field, this third edition continues to be relevant to food industry researchers, food manufacturers, graduate and postgraduate students, particularly in food, pharmaceutical, and cosmetic sciences. Introduces to food hydrocolloids considering regulatory aspects and functional characteristics Examines the manufacture, structure, function, and applications of over twenty-five hydrocolloids Brings a detailed overview of the function of hydrocolloids as emulsifiers, rheological modifiers, film formers, and encapsulation agents

The aim of this book is to show the potential of natural hydrocolloids and active agents to develop sustainable edible packaging materials for food preservation. For this, the current and future sources of natural hydrocolloids have been reviewed along with their extraction methods, impact on health and ability to form different packaging such as film, casing, coating, mat, pad, etc. Similarly, natural active compounds were evaluated carefully considering their sources, extraction methods, regulatory status, and compatibility with edible packaging. The book emphasizes the recent developments in methods, strategies and technologies employed to enhance the performance of antimicrobial, antioxidant and bioactive packaging. The basic testing methods used to evaluate antimicrobial and antioxidant activity of edible packaging in model media and food were discussed, and carefully selected example active edible packaging applications for different food categories were provided with critical details such as the thin balance between effectiveness of packaging and sensory properties of food. As such, it helps in understanding necessary parameters in designing an effective active edible packaging that is applicable to the target food category. Moreover, readers are primed for the first time on how to develop a fully natural antimicrobial, antioxidant or bioactive edible food packaging. This book is different from most of the similar books' avail as it provides neither methodologies about classical active packaging based on chemicals and fossil polymeric films nor is it a thorough collection of different food packaging applications. It is also not a book that concentrates on physicochemical characterization methods and engineering aspects of packaging. Instead, this is a book that provides systematic knowledge about key methods of evaluating natural resources, agro-industrial wastes and by-products for development of edible packaging, and concentrates on concepts, strategies, technologies, and applications of active edible packaging based solely on natural components. It is designed to share both positive and negative experiences in an emerging field that is expected to play a central role in improving food safety and quality, human health and environmentally friendly practices.

This book is an essential manual for professionals and students who wish to deepen their knowledge of food additives that modify the texture of food, thickeners and gelling agents. When it comes to food technology, hydrocolloids are generally introduced as additives. Other ingredients, not considered additives, are also hydrocolloids, for example proteins and starches. This manual only focuses on those considered additives, except modified starches. Newly translated from Spanish to English, Hydrocolloids in Food Product Development is written by four experts in their field who are familiar with offering technical advice to companies related to the manufacturing of food. After an introductory chapter that reviews chemical characteristics, the hydration and solubilization of hydrocolloids, the preparation of hydrocolloids solutions, and technological functions, subsequent chapters present different hydrocolloids used in food technology and describe its technical features and its most common uses. Key Features: Describes technical and utilization characteristics of thickeners and gelling agents Details the origin, physical-chemical characteristics, form of use, function, synergies, incompatibilities and examples of use Graphs, tables, photographs and diagrams provided in full color for easy reading comprehension This practical manual is designed so that food industry technicians and chefs may easily consult while doing their daily work, or so that students of degrees related to food technology may use it as a reference book.
