This book describes green alternatives to conventional food processing and their effect on food quality. It starts by outlining the principles of green chemistry which provide a basis for the processing methods described in later chapters. This is followed by a discussion of legal and policy issues which further justify the use of such technologies and the constraints and benefits of current regulations. The book then goes on to describe the principles and applications of the major green technologies available to the food industry. The degree to which they are already in commercial use and developments needed to extend their use in the future are addressed.
