This book concentrates on the more recent methods and techniques for separating food components and products of the biotechnology industry. Each chapter deals with a specific type or area of application and includes information on the basic principles, industrial equipment available, commercial applications and an overview of current research and development and some of the heat and mass transfer considerations in batch and continuous processes Separations from solids, liquids and gases are briefly discussed. A summary is provided of the more conventional separation techniques such as screening, filtration and centrifugation, and techniques for

Chapter 2 Supercritical fluid extraction and its application in the food industry DAVID STEYTLER, School of Chemical Sciences, University of East Anglia, Norwich NR4 7TJ 2.1 INTRODUCTION Solvent extraction is one of the oldest methods of separation known and certainly dates back to prehistory. The science of solvent extraction has evolved accordingly over a long period of time and much progress has been made in the understanding of solvation and

Chapter 6 Ion-exchange and electrodialysis ALISTAIR S. GRANDISON, Department of Food Science and Technology, The University of Reading, Reading RG6 6AP, UK Ion-exchange and electrodialysis are distinct methods of separation, but can conveniently be treated together, as the basic criterion for separation in both cases is the molecular

Chapter 3 Pressure-activated membrane processes M. J. LEWIS, Department of Food Science and Technology, The University of Reading, Reading RG6 6AP 3.1 INTRODUCTION Over the last 30 years, a number of membrane processes have evolved, which make use of a pressure driving force and a semi-permeable membrane in order to effect a separa- tion of components in a solution or colloidal dispersion. The separation is based mainly on molecular size, but to a lesser extent on shape and charge. The three main processes
