Renowned experts give all essential aspects of the techniques and applications of graft copolymers based on polysaccharides. Polysaccharides are the most abundant natural organic materials and polysaccharide based graft copolymers are of great importance and widely used in various fields. Natural polysaccharides have recently received more attention due to their advantages over synthetic polymers by being non-toxic, biodegradable and available at low cost. Modification of polysaccharides through graft copolymerization improves the properties of polysaccharides. Grafting is known to improve the characteristic properties of the backbones. Such properties include water repellency, thermal stability, flame resistance, dye-ability and resistance towards acid-base attack and abrasion. Polysaccharides and their graft copolymers find extensive applications in diversified fields. Applications of modified polysaccharides include drug delivery devices, controlled release of fungicides, selective water absorption from oil-water emulsions, purification of water etc.

Over the past five years, the immense financial pressure on the development and manufacturing of biopharmaceuticals has resulted in the increasing use and acce- ance of disposables, which are discarded after harvest and therefore intended only for single use. In fact, such disposables are implemented in all the main bioprocess production stages today and an even higher growth than those in the biopharmac- tical market is predicted (reaching double figures). Alongside disposable filter capsules, membrane chromatography units, tubing, connectors, flexible containers processing or containing fluids, freezer systems, mixers and pumps, and fully c- trolled disposable bioreactors of up to 2,000 L culture volume are already available on the market. Numerous studies highlight the advantages of disposable bioreactors and reveal their potential for simple, safe and fast seed inoculum production, process devel- ment and small as well as middle volume production (e.g. bioactive substances, viruses for vaccines and gene therapies etc.). They suggest that such disposable bioreactors (typically characterized by the cultivation chamber or bag from plastic materials) may be advantageous for plant, animal and microbial cells. Running industrial activities such as CFD-modelling, development of single-use process monitoring and control technology, and standardized film formulations are attempting to resolve the limitations of the current disposable bioreactors. These achievements, along with substantial improvements in product yield, will reduce the use of stainless steel in the biomanufacturing facilities of the future.

Historically, most of the research into carbohydrates as functional ingredients focused on the improvement of appearance, taste, mouth-feel, and stability. The growing interest in functional foods, however, is demanding a critical look at the beneficial nonnutritive effects of carbohydrates on human health. Furthermore, there is a need to establish definitive relations among the structure, physical property, and physiological function of these bioactive compounds. As more of the benefit and functional versatility of carbohydrates is revealed, it is clear that any future research and recommendation must be based on a solid synthesis of multidisciplinary findings including epidemiological, metabolic, and clinical nutritional data. Through clinical and epidemiological studies, Functional Food Carbohydrates addresses the specific classes of carbohydrates that seem to exert health-enhancing effects. The text begins with in-depth treatments of the chemistry, physical properties, processing technology, safety and health benefits of a variety of carbohydrates including cereal beta-glucans, microbial polysaccharides, chitosan, arabinoxylans, resistant starch, and other polysaccharides of plant origin. The authors then discuss the physiological and metabolic effects that a variety of carbohydrates have on specific chronic diseases such as cancer, diabetes, cardiovascular disease, obesity, and various gastrointestinal disorders. The final chapters discuss the regulatory and technological aspects of using carbohydrates as functional foods. Specifically, the authors consider the safety and efficacy of pre-, pro-, and synbiotics, and the potential use of carbohydrates as delivery vehicles for other bioactive compounds. With contributions from experts specializing in food chemistry and technology, as well as human nutrition and physiology, this text illuminates the link between the behavior of carbohydrate compounds and their beneficial end-result on human health.

Lignin, a plant constituent, is the second most abundant biopolymer on earth. Every year, the pulp and paper industry generates over 45 million metric tons of lignin as a by-product of chemical wood pulps and uses about 10 million metric tons of lignin as a component of mechanical wood pulps. The majority of the by-product lignin is being used internally as a low-grade fuel for the chemical pulping operation, while the lignin-rich mechanical wood pulps are being used mainly to make short-life paper products such as newsprint and telephone directories because of the light-instability of lignin. There is a tremendous economic incentive to find better uses of lignin and to expand the markets of mechanical wood pulps.
In Asia and other areas of the world where forest resources are less abundant, non-wood plant materials such as straw and bamboo have been used to make paper products for many centuries. The effective isolation and product development of lignin from chemical pulping of non-wood materials have become increasingly more important because internal use of the non-wood pulping spent liquors is difficult and the traditional way of discharging them to the environment is no longer acceptable.
This volume covers recent developments in chemical modification and utilization of lignin as a component of polymeric materials such as starch films, conducting polymers, polyurethanes and thermoplastics, and as a key building block to make carbon fibers, soil conditioners, nitrogenous fertilizers, and pulping catalysts. It also describes recent advances in chemical modification of lignin aimed at the photostabilization and upgrading of lignin-rich mechanical wood pulp and paper.

This book is a "world first," since the furfural industry has been traditionally secretive to the point of appearing shrouded in clouds of mystery. Even renowned encyclopedic works have published but scant and often erroneous information on the subject.
Striking a healthy balance between theory and practice, the book leads the reader from reaction mechanisms and kinetics to the technology of making furfural by various old and new processes, using conventional raw materials or sulfite waste liquor. Detailed discussions of means of increasing the yield are of great chemical and technological interest as well as of immense economic importance.
From furfural proper, the treatise shifts to the fascinating field of wanted and unwanted by-products ranging from largely unutilized carboxylic acids to troublesome impurities such as 5-methyl furfural and 2-furyl methyl ketone, and then to extremely valuable serendipitous flavor compounds such as diacetyl and 2,3-pentanedione. A wide variety of derivatives are discussed; considerable space is devoted to polytetrahydrofuran, an important building block of stretchable synthetic fibers, while furan resins from both furfural and furfuryl alcohol are given the attention commensurate with their industrial importance.
Notable supplementary chapters cover the in-line measurement of furfural, the treatment of furfural waste water, and various aspects of corrosion. A chapter on the applications of furfural elaborates not only traditional uses in extracting petroleum and vegetable oils but also the sensational discovery that furfural is a highly effective "indirect nematocide." Without becoming toxic, it changes the microflora of the soil by stimulating bacteria antagonistic to nematodes, thereby reducing the nematode population to zero, at an unprecedented low price. It is believed that this application will be the principal outlet for furfural in the future.
A comprehensive list of physical properties, some never published before, make the book an indispensable companion for producers, users and researchers alike.
