role in maintaining profitability Traditional thermal processing techniques have been effective in maintaining a safe food supply that is acceptable to consumers However, increasing energy costs and the desire to purchase ‘green’ environmentally responsible products have been a stimulus for the development of alternative technologies Furthermore, some products may undergo quality loss at high temperatures, which can be avoided by many alternative processing methods This book is intended to provide food industrialists, professional academics and graduate students with a review of the major alternative technologies that could be used to reduce energy costs while maintaining safety and quality The introductory chapters provide the reader with an important discussion of the general principles of green technology underpinning the new technologies and the legal developments that are influenced by emerging new processing methods The authors have all made significant contributions to their field and are well qualified to comment on the value and future significance of green food processing methods It is hoped that this book will serve as an introduction for those interested in gaining an understanding of various ‘green’ alternative food processing technologies and the their role in the future of the food industry Andrew Proctor University of Arkansas RSC Green Chemistry No
