i Separation, extraction and concentration processes in the food, beverage and nutraceutical industries © Woodhead Publishing Limited, 2010 ii Related titles: Separation processes in the food and biotechnology industries (ISBN 978-1-85573-287-2) This book reviews methods and techniques for separating food components and products of the biotechnology industry. The introduction focuses on food composition and some of the conventional separation techniques. Subsequent chapters deal with each specific type or area of application individually and include information on the basic principles, industrial equipment available, commercial applications and an overview of research and development. Novel enzyme technology for food applications (ISBN 978-1-84569-132-5) The food industry is constantly seeking advanced technologies to produce valueadded, nutritionally-balanced products for consumers in a sustainable fashion. Since enzymes are so specific in their action, they are a useful biotechnological processing tool and by controlling the action of enzymes, innovative food ingredients and higher quality food products can be produced. Part one of Novel enzyme technology for food applications covers the principles of industrial enzyme technology, including methods to develop and tailor enzymes for food bioprocessing. Part two introduces the reader to novel applications of enzymes for the production of improved ingredients and food products. Food processing technology (Third edition) (ISBN 978-1-84569-216-2) The first edition of Food processing technology was quickly adopted as the standard text by many food science and technology courses. The publication of a completely revised and updated third edition consolidates the position of this textbook as the best single-volume introduction to food manufacturing technologies available. The third edition has been updated and extended to include the many developments that have taken place since the second edition was published. In particular, advances in microprocessor control of equipment, ‘minimal’ processing technologies, functional foods, developments in ‘active’ or ‘intelligent’ packaging, and storage and distribution logistics are described. Technologies that relate to cost savings, environmental improvement or enhanced product quality are highlighted. Additionally, sections in each chapter on the impact of processing on food-borne micro-organisms are included for the first time.

melting point of the solid decreases as the pressure increases owing to the increasing solubility of gas in the solid The second type of solidSCF phase behaviour (Fig 1.7b) is typical for systems in
