Physicochemical And Enzymatic Modification Of Gums

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.

Industrial Gums: Polysaccharides and their Derivatives, Second Edition covers the biochemical approaches to the modification and production of natural synthetic gums. This book is organized into two main parts encompassing 31 chapters. The first part deals with natural gums, including seaweed extracts, plant exudates and extracts, seed gums, and animal extracts. Considerable chapters in this part discuss the preparation, structure, derivatives, biosynthesis, and economics of these natural gums. The second part explores the industrial production, structure, and properties of synthetic gums, such as scleroglucan, dextrans, and starch and cellulose derivatives. Scientists, research workers, and manufacturers of both natural and synthetically prepared gums will find this book invaluable.

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.

Enzyme inactivation in fruits and vegetables is of utmost importance regarding food quality during storage. This new volume explores important emerging technologies for the inactivation of enzymes in the design and preservation of food. The book covers the basic concepts and chemical methods and then introduces novel processing technologies for inactivating food enzymes. The new technologies are many: pulsed electric field, ultraviolet and light-emitting diodes, ohmic heating, dense-phased carbon dioxide, cold plasma, ultrasonication, microwave processing, radiofrequency, extraction, and others. The volume also looks at the design of nutraceutical-based functional foods, specific foods for gut-microbiodata, the use of omega-3 fatty acids to fortify food products, and the characteristics of dairy-based dry powders, and characteristics of millet starches. It also considers the role of the bioactive compounds and metal ions for catalases secreted by medicinal plants and mushrooms for enzyme inactivation and biosensing, along with the role of bionanomaterials in nanoencapsulation and catalysis.
