Natural gums are polysaccharides consisting of multiple sugar units linked together via glycosidic linkages. Most natural gums reveal appropriate safety for oral consumption in the form of food additives or drug carriers. Challenges related to the utilization of natural polysaccharides, however, include uncontrolled rates of hydration, pH dependent solubility, viscosity reduction during storage, and weak interfacial properties. Modification provides an efficient route for not only removing such drawbacks but also improving physicochemical properties, such as solubility, viscosity and swelling index, and introducing new properties for varied applications.This book provides a comprehensive review of the various modifications on gums to make them suitable for food, cosmetic and pharmaceutical industries. The book is divided in four parts: an introduction to natural gums followed by in-depth coverage of chemical modification, physical modification, and enzymatic modification of gums. Each chapter includes reaction mechanisms, physicochemical properties, rheological properties, interfacial properties, applications and future perspectives. Presenting a succinct account on gum modification from a practical point of view, this book is a helpful reference for academic and industrial scientists and engineers in food technology, materials chemistry, pharmaceuticals, chemical, industrial, and applied engineering, biochemistry, and biopolymers.

Natural Gums: Extraction, Properties, and Applications provides thorough, methodical coverage of a range of natural gums. These naturally forming polysaccharides or complex carbohydrates offer advantageous properties and a range of possible applications. The book begins by introducing fundamental knowledge regarding natural gums, including structures and properties, functionalization, gelatin behavior, and characterization techniques. Subsequent sections of the book provide in-depth chapters, each guiding the reader through the extraction, properties and applications of a specific gum type, covering plant-based, animal-based, microbial-based, and marine-based natural gums. Finally, the future potential of natural gums, and their implications in a circular economy approach, are considered. This is an informative resource for researchers and advanced students in bio-based materials, polymer science, chemistry, bioengineering, materials science, and food science, as well as industrial scientists and R&D professionals with an interest in natural gums and bio-based materials for advanced applications. - Explains origin, extraction, processing and structural analysis of natural gums - Offers in-depth information on specific natural gum types, their properties and potential uses - Explores a range of advanced applications across food, biomedicine, pharmaceuticals, and more

Functionality of Food Proteins: Mechanisms, Modifications, Methods of Assessment and Applications provides researchers and users of plant-based proteins with the latest developments on their functionality at the molecular and ingredient level, and in food applications. The book discusses the biological, chemical and physical principles behind the techno-functional and nutritional properties of proteins, existing methods of functionality assessment, and protein modification for functional enhancement. With market demand for protein ingredients, several lesser known sources are being utilized to develop new protein ingredients and products, with some intended to replace, partially or wholly, traditional proteins such as egg, milk, meat, soy and vital gluten. Depending on the source and processing into ingredients, the ability of these proteins to satisfy techno-functional and nutritional requirements in the final food product may differ. Science-based knowledge is needed in the area of protein functionality for making decisions along the value chain, from production on the land to processing and formulation. - Provides fundamentals of the properties that contribute to functionality (nutritional and techno-functional properties) of proteins in food systems and their relationship to protein molecular structure - Describes fundamentals of the assessment of functional properties of protein with existing definitions and food systems - Explores fundamentals of modification strategies employed to alter nutritional and techno-functional properties to enhance value of proteins in food - Includes examples of plant protein-based products (in food systems) in which the role of nutritional and techno-functional properties is described

Lipid Modification by Enzymes and Engineered Microbes covers the state-of-the art use of enzymes as natural biocatalysts to modify oils, also presenting how microorganisms, such as yeast, can be designed. In the past ten years, the field has made enormous progress, not only with respect to the tools developed for the development of designer enzymes, but also in the metabolic engineering of microbes, the discovery of novel enzyme activities, and in reaction engineering/process development. For the first time, these advances are covered in a single-volume that is edited by leading enzymatic scientist Uwe Borchscheuer and authored by an international team of experts. - Identifies how, and when, to use enzymes and microbes for lipid modification - Provides enzymatic, microbial and metabolic techniques for lipid modification - Covers lipases, acyltransferases, phospholipases, lipoxygenases, monooxygenases, isomerases and sophorolipids - Includes lipid modification for use in food, biofuels, oleochemicals and polymer precursors

This book is about the chemical properties of starch. The book is a rich compendium driven by the desire to address the unmet needs of biomedical scientists to respond adequately to the controversy on the chemical properties and attendant reactivity of starch. It is a collective endeavor by a group of editors and authors with a wealth of experience and expertise on starch to aggregate the influence of qualitative and quantitative morphological, chemical, and genetic properties of starch on its functionalities, use, applications, and health benefits. The chemical properties of starch are conferred by the presence, amount and/or quality of amylose and amylopectin molecules, granule structure, and the nature and amounts of the lipid and protein molecules. The implication of this is comprehensively dealt with in this book.

This book provides comprehensive and up-to-date knowledge relating to the morphological, structural, and functional characteristics of tuber starches, particularly in relation to their applications in food and industry. In recent years there has been significant progress and extensive research conducted on tropical root starches and especially on some of the lesser known tuber crop starches. There has also been a shift towards using biomaterials in place of synthetic materials in various applications. As researchers investigate the availability of natural products with similar properties, starch has been identified as a reliable alternative to these synthetic materials. The book is a valuable resource for researchers and students, plant breeders, and commercial producers working with, or considering working with, tropical tuber starches.
