Food and Feed Extrusion Technology: An Applied Approach to Extrusion Theory

Angebote / Angebote:

This book presents the theory behind extrusion technology, as used for food and feed products, in a way which can be readily applied in practice. It provides good fundamental understanding, but presented in the context of practical application, so that readers can understand how it applies in a real manufacturing situation.This book is relevant to all types of extruded human foods and animal feeds, and all types of equipment used to produce them: single- and twin-screw extruders, and specialised snack food machines. It considers how the equipment and processes operate, and how the process conditions interact with the ingredients used.Understanding the theory behind the process - and how it applies in practice - means that formulations and processes can be designed to be more robust, appropriate equipment can be selected for the required duty, and effective operating procedures and guidelines can be developed - leading to reliable processes and consistent product.The authors bring decades of industry and research experience to this book. Dennis Forte is a chemical engineer by training, who has spent his career in extrusion and related processes in areas of human food (breakfast cereals, snacks, pasta, confectionary, texturised vegetable protein), pet foods (dry, semi-moisture, wet texturised) and aquafeeds. He has worked in these areas with both multinational corporations and small manufacturers. Gordon Young entered the field of extrusion through research and teaching at the University of Queensland in Australia, gaining practical experience through industry project work and training.
