The enzymatic polymerization of phenolic compounds has been generating interest in several fields such as food, cosmetics, and pharmaceuticals. These compounds are employed for their antioxidant properties; however, their use is limited by their low solubility and thermal stability. Polymerization can improve their solubility and their thermal stability though and create new properties which are dependent on the molecular mass and the structure of polymers. The reaction yield, the polydispersity, the molecular mass, the structure and the properties of synthesized polymers can be controlled by the mode of control of the reaction and by the reaction conditions. Enzymatic polymerization of phenolic compounds by oxidoreductases analyze the processes used and the key factors (temperature, solvent, origin of the enzyme, structure of the substrate, reactor design, ...) which control the polymerization of phenolic species by these oxidoreductase enzymes in order to obtain polymers with desired characteristics and properties.

Enzyme Chemistry of Phenolic Compounds documents the proceedings of the Plant Phenolics Group Symposium held at Liverpool on April 11-12 1962. This book focuses on the interaction of enzymes and phenolic compounds, oxidation-reduction systems in plants and microorganisms, and phenolase complex. Other topics discussed include purification of phenol oxidases; enzyme-substrate specificity in potato polyphenol oxidase; tocopherols; and role of ubiquinone and plastoquinone in plant metabolism. Hydrolytic enzymes; enzyme inhibition by phenolic compounds; tannin inhibition of plant mitochondria; and aromatic acid-reducing systems in fungi are also deliberated in this selection. This publication is beneficial to students and biochemists researching on enzyme and phenolic compounds.

The sheer volume of topics which could have been included under our general title prompted us to make some rather arbitrary decisions about content. Modification by irradiation is not included because the activity in this area is being treated elsewhere. We have chosen to emphasize chemical routes to modification and have striven to pre sent as balanced a representation of current activity as time and page count permit. Industrial applications, both real and potential, are included. Where appropriate, we have encouraged the contributors to include review material to help provide the reader with adequate context. The initial chapter is a review from a historical perspective of polymer modification and contains an extensive bibliography. The remainder of the book is divided into four general areas: Reactions and Preparation of Copolymers Reactions and Preparation of Block and Graft Copolymers Modification Through Condensation Reactions Applications The chemical modification of homopolymers such as polyvinylchlo ride, polyethylene, poly(chloroalkylene sulfides), polysulfones, poly chloromethylstyrene, polyisobutylene, polysodium acrylate, polyvinyl alcohol, polyvinyl chloroformate, sulfonated polystyrene; block and graft copolymers such as poly(styrene-block-ethylene-co-butylene block-styrene), poly(I,4-polybutadiene-block ethylene oxide), star chlorine-telechelic polyisobutylene, poly(isobutylene-co-2,3-dimethyl- 1,3-butadiene), poly(styrene-co-N-butylmethacrylate); cellulose, dex tran and inulin, is described.

The integration of enzymes in food processing is well known, and dedicated research is continually being pursued to address the global food crisis. This book provides a broad, up-to-date overview of the enzymes used in food technology. It discusses microbial, plant and animal enzymes in the context of their applications in the food sector; process of immobilization; thermal and operational stability; increased product specificity and specific activity; enzyme engineering; implementation of high-throughput techniques; screening of relatively unexplored environments; and development of more efficient enzymes. Offering a comprehensive reference resource on the most progressive field of food technology, this book is of interest to professionals, scientists and academics in the food and biotech industries.
