Book Description
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.

Book Description
Naturally occurring polysaccharides from plant exudates have been in use from many decades in immense quantities. Natural gums are natural polymers, which mainly consists of carbohydrates sometimes with small amounts of proteins and minerals. Gum and its derivatives are widely used in various industries as per its needs. The appearance and properties of natural gums determine their commercial value and end use. Due to their extraordinary, unrivalled technological & functional properties gum is used in many industries. Gums not only modify viscosity and consistency, they also often attenuate odour, taste and flavour intensity. Adhesive or sealant is a mixture in a liquid or semi-liquid state that is capable of holding materials together by surface attachment. Adhesives and sealants are used as a raw material for the manufacturing industry or for the service of different processing industries. Adhesives and sealants virtually touch every part of our lives. The adhesives and sealants are two chemically similar but functionally different groups of formulated products. There is no end in sight to the new materials, new formulation, and new uses to which adhesives and sealants will be put in the future. Some of the fundamentals of the book are advantages of adhesive bonding, hybrids and coupling agents, adhesive films, designing polymers for adhesives, fundamentals of adhesion, designing polymers for adhesives, thermodynamics of adhesion, casein and mixed protein adhesives, lime-free casein adhesives, foil to paper laminating adhesives, casein and protein blend glues as wood adhesives, chemistry of protein blend glues, natural rubber adhesives, vulcanizing latex adhesives, solution adhesives from natural rubber, halogenated butyl rubber, butyl rubber and poly isobutylene lattices, polysulfide sealants and adhesives etc. This book covers a wide range of polymeric adhesives and sealants, gums along with their essential formularies, distinguished by applications and based on technology. The main areas covered in details are the basic fundamentals, properties, uses and applications, formulations and chemistry, methods of manufacturing and lastly testing methods. This book will be very resourceful to its readers who are just beginners in this field and also to upcoming entrepreneurs, engineers, existing industries, technologist, technical institution etc.

Book Description
A 3-volume reference set you'll use every day. • Suppose you are the regulatory affairs manager for a food company, and your boss calls about "beet red", a coloring agent touted by a salesman as "natural". Your boss needs to know if this claim is true. How do you find out? • Perhaps you are an attorney for a company manufacturing ethnic marinade mixes and a customer charges that the chemical cinnamaldehyde, which the mixes contain, is being tested for carcinogenicity by the National Toxicology Program. Is your company manufacturing food that is potentially toxic? With the Encyclopedia of Food and Color Additives, the answers are at your fingertips: You quickly look up "Beet Red" and find it is indeed natural, a product of edible beets.
