Considered magicians of the ingredient world, gums (hydrocolloids) are used in a variety of food applications. They possess excellent thickening, binding, emulsifying, suspension, and viscosity properties. The first comprehensive reference produced on gums in 60 years, this work is organized by taxonomy. Each entry contains the botanical name and synonyms of the tree from which it is exuded, common names, geographic distribution, chemical characteristics and structural features, physical properties, and industrial and food applications. The uses of other parts of the trees from which the gums originate are also detailed. Entries are illustrated with color photos and line drawings.

Forest trees cover 30% of the earth's land surface, providing renewable fuel, wood, timber, shelter, fruits, leaves, bark, roots, and are source of medicinal products in addition to benefits such as carbon sequestration, water shed protection, and habitat for 1/3 of terrestrial species. However, the genetic analysis and breeding of trees has lagged behind that of crop plants. Therefore, systematic conservation, sustainable improvement and pragmatic utilization of trees are global priorities. This book provides comprehensive and up to date information about tree characterization, biological understanding, and improvement through biotechnological and molecular tools.

This book provides the whole spectrum of polysaccharides from basic concepts to commercial market applications. Chapters cover various types of sources, classification, properties, characterization, processing, rheology and fabrication of polysaccharide-based materials and their composites and gels. The applications of polysaccharides include in cosmetics, food science, drug delivery, biomedicine, biofuel production, marine, packaging, chromatography and environmental remediation. It also reviews the fabrication of inorganic and carbon nanomaterials from polysaccharides. The book incorporates industrial applications and will fill the gap between the exploration works in the laboratory and viable applications in related ventures.

This reference book provides a comprehensive overview of natural gums, resins, and latexes of plants with a focus on their chemistry, biological activities, and practical uses. The content is divided into five main sections each of which contains chapters contributed from valuable experts in their field. Naturally occuring plant products have quite diverse applications in many different industries. The book aims to highlight the important aspects of plant-based gums, resins and latexes as well as provide a strategic framework for further research and development activities on these bioproducts. It will appeal to a broad audience such as biologists, pharmacologists, pharmacists, food technologists and medical practitioners. It is also a useful resource for research investigators of the healthcare industry, academia and students of biomedical sciences.

fudustrial uses of polysaccharides centre on their ability to thicken or structure many times their own weight of water, or in other words to control the rheology of hydrated systems. Until comparatively recently, however, objective characterisation of polysaccharide rheology, except in a few specialist research laboratories, was largely confined to compression of gels, simple measurements of solution viscosity, often in ill-defined geometries, and imitative tests intended to reflectproductperformance in specific areas ofend-use. Several factors have combined to bring a wider range of rheological techniques into common use. One is the increasing practical importance of systems that cannot adequately be described as solids or liquids, such as 'weak gels' and spreadable pastes. fu parallel, routine characterisation of such systems has become economically feasible with the development of a new generation of comparatively inexpensive computer-controlled instruments. There has also been a change ofemphasis from phenomenologicaldescription ofproduct texture towards the use of rheological measurements to probe the underlying molecular and supramolecular structures and the processes by which they are formed. As a result, even the most pragmatic producers and users of industrial polysaccharides are probably now familiar with terms such as creep compliance, stress overshoot and the ubiquitous G' and G", although perhaps not fully understanding their precise meaning or practical significance. A definitive text giving a rigorous description of the rheological approaches relevant to polysaccharide systems is therefore appropriate and timely. Romano Lapasin and Sabrina Priel are to be congratulated for tackling the daunting but worthwhile taskofproducing such avolume.

Polysaccharide gums have a wide range of applications due to their hydrophilic properties. They have been used as a gelling agent, encapsulating agent, thickener, emulsifier, and stabilizer. Sourcing natural gums from botanical and plant sources has become an important focus in producing acceptable food ingredients in liquids and semi-solid forms. This is mainly because of the positive attitude of consumers toward plant-based gums rather than other gums from animal and microbial sources. Gum karaya, also known as Indian tragacanth, is a vegetable gum produced as an exudate by trees of the genus Sterculia. Gum karaya has very strong swelling properties, high viscosity, and very poor solubility because of its acetyl groups. Therefore, it is mainly used in cosmetics and pharmaceuticals. Gum karaya is one of the least-soluble gums used for many industries, such as petroleum and gas, textile, paper and pulp, leather and allied products, ammunition and explosives, electrical appliances, adhesives, confectionery, medicine, pharmaceuticals, and cosmetics. Because of the crude tapping method and overexploitation, the population of karaya trees has markedly declined. In the absence of cultivation of this tree on the regular plantation, there is grave concern about the loss of wild germplasm of S. aurens. As gum karaya is vital for the tribal economy and its trade value is substantial, there is a pressing need to develop a scientific and sustainable tapping method to increase the yield and ensure the survival of the tapped trees. There is also a need for a large-scale plantation of gum karaya. People are becoming health-conscious and are taking natural products as food ingredients. This book will be useful to all the people interested in natural food additives. This book gives the details of gum karaya–yielding species and their distribution. Scientific methods of gum tapping are given for sustainable gum production. Propagation methods, both field and in vitro, are given. Uses of gum karaya, in cosmetics, pharmaceuticals, and food, are given. Genetic diversity and biotechnological intervention for the improvement of gum karaya–yielding species are included. Threats and conservation of gum karaya–yielding species are given.
