Food Processing Technology: Principles and Practice, Fifth Edition includes emerging trends and developments in food processing. The book has been fully updated to provide comprehensive, up-to-date technical information. For each food processing unit operation, theory and principles are first described, followed by equipment used commercially and its operating conditions, the effects of the operation on micro-organisms, and the nutritional and sensory qualities of the foods concerned. Part I describes basic concepts; Part II describes operations that take place at ambient temperature; Part III describes processing using heat; Part IV describes processing by removing heat; and Part V describes post-processing operations.

This book continues to be the most comprehensive reference in the field, covering all processing unit operations in a single volume. The title brings key terms and definitions, sample problems, recommended further readings and illustrated processes.

Key Features

Presents current trends on food sustainability, environmental considerations, changing consumer choices, reduced packaging and energy use, and functional and healthy/plant-based foods
Includes highly illustrated line drawings and/or photographs to show the principles of equipment operation and/or examples of equipment that is used commercially
Contains worked examples of common calculations
