The fourth edition of this leading textbook presents the engineering concepts and unit operations used in food processing in a classroom-proven and unique blend of principles with applications. Describing the application of a particular principle followed by the quantitative relationships that define the related processes, each chapter also includes solved examples and problems to evaluate reader comprehension. Authors Singh and Heldman use their many years of teaching to present food engineering concepts in a logical progression that covers the standard course curriculum making it easily adaptable for each classroom. WHY ADOPT THIS NEW EDITION? * NEW CHAPTERS ON: - Supplemental Processes - Filtration - Sedimentation - Centrifugation - Mixing - Extrusion Processes for Foods - Packaging Concepts - Shelf Life of Foods * EXPANDED INFORMATION ON: - Transport of granular foods and powders - Process controls and measurements - Emerging technologies such as high pressure and pulsed - Electric field Design of plate heat exchangers - Impact of fouling in heat transfer processes - Use of dimensional analysis in solving problems * Author Web site with animated versions of figures * Examples throughout each chapter, presented in "Given - Approach - Solution" format for clear presentation of key concepts * End of Chapter Problems to assess comprehension * List of Symbols * "Advanced" level questions called out in a separate section Key equations highlighted * Written to follow the typical Food Engineering course, making it easily adaptable for each classroom

Introduction to food engineering

Cereals, legumes, oilseeds, fruits, and vegetables are the most important food crops in the world, with cereal grains contributing the bulk of food calories and proteins worldwide. Generally, the supply of grains and other food can be enhanced by increasing production and by reducing postharvest losses. While food production has increased significantly over the last few decades, minimizing huge postharvest losses as well as utilizing their by-products/wastes is the optimal way for a country to become self-sufficient in food. Postharvest Technology and Food Process Engineering combines these two subject areas as it covers both the primary processing of cereals, pulses, fruits, and vegetables and utilization of by-products/biomass. This book covers postharvest food preservation and processing methods, with an emphasis on grains. It is divided into five parts: Grain-Properties, Drying and Dryers Grain Storage Parboiling and Milling By-Products/Biomass Utilization Food Process Engineering The text covers grain structure and composition, psychrometry, the theory and methods of grain drying, and design, testing, specification and selection of grain dryers. It describes processes such as parboiling of grain, hydrothermal treatment of grain, and milling of rice and other grains and pulses. The text also addresses biomass utilization and conversion technologies for energy, chemicals, food, and feed. The final section on food process engineering examines postharvest management including cooling, and packaging, and discusses preservation and processing, factors that affect deterioration, and various industrial preservation methods of fruits and vegetables. It also provides an overview of food chemistry and covers food engineering operations, including fluid mechanics and heat transfer.
