Food processing technology : principles and practice / P.J. Fellows

館藏資訊

Widely regarded as a standard work in its field, this book introduces the range of processing techniques that are used in food manufacturing. It explains the principles of each process, the processing equipment used, operating conditions and the effects of processing on micro-organisms that contaminate foods, the biochemical properties of foods and their sensory and nutritional qualities. The third edition is divided into five parts. Part one describes some important basic concepts. Part two describes unit operations that take place at ambient temperature or involve minimum heating of foods. Part three includes operations that heat foods to preserve them or to alter their eating quality. Part four describes operations that remove heat from foods to extend their shelf life with minimal changes in nutritional quality or sensory characteristics. Part five describes post-processing operations, including packaging and distribution logistics. The third edition has been substantially rewritten, updated and extended to include the many developments in food technology that have taken place since the second edition was published in 2000. Nearly all unit operations have undergone significant developments, and these are reflected in the large amount of additional material in each chapter. In particular, advances in microprocessor control of equipment, "minimal" processing technologies, genetic modification of foods, functional foods, developments in "active" or "intelligent" packaging, and storage and distribution logistics are described. Developments in technologies that relate to cost savings, environmental improvement or enhanced product quality are highlighted. Additionally, sections in each chapter on the impact of processing on food-borne micro-organisms are included for the first time.
