Now in a fully revised and updated second edition, this volume provides a contemporary overview of food processing/packaging technologies. It acquaints the reader with food preservation processes, shelf life and logistical considerations, as well as packaging materials, machines and processes necessary for a wide range of packaging presentations. The new edition addresses environmental and sustainability concerns, and also examines applications of emerging technologies such as RFID and nanotechnology. It is directed at packaging technologists, those involved in the design and development of packaging, users of packaging in food companies and those who specify or purchase packaging. Key Features: • An up-to-date and comprehensive handbook on the most important sector of packaging technology • Links methods of food preservation to the packaging requirements of the common types of food and the available food packages • Covers all the key packaging materials - glass, plastics and paperboard • Fully revised second edition now covers sustainability, nanotechnology and RFID
