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 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 5 Microfiltration A. S. GRANDISON, Department of Food Science and Technology, The University of Reading, Reading RG6 6AP and T.J. A FINNIGAN, Marlow Foods, Middlesbrough. 5.1 INTRODUCTION Microfiltration (MF) is the oldest membrane technology, having been used several

Chapter 4 Ultrafiltration M.J. LEWIS, Department of Food Science and Technology, The University of Reading RG6 6AP 4.1 INTRODUCTION Ultrafiltration offers the opportunity to concentrate large molecular weight components without the application of heat or a change of phase. Such components are rejected
