This book offers a combination of theoretical support, practical examples, process applications, and recent findings on diverse aspects of food science and engineering, such as rheology, heat transfer, evaporation, osmotic dehydration, air drying, ultrasound and deep-fat frying. Topics upon selected fluids, powders, cheese, concentrated foods, and frozen dough are also included. Presenting an interesting, complete and current vision of important food processing and food engineering, food products and food technologies, the manuscript is a useful tool for teaching, processing and researching. The book could be used as a textbook by students, finding in it some academic themes such as: rheological applications an its relation with moment transport and flow, measure of textural attributes for cheese, particle size distributions for food powders; also, the fundamentals of heat transfer focused to explain the convective heat transfer evaluation, the heat transfer complications due to the fouling formation, and the evaporation of food liquids; mass transfer principles and applications on osmotic concentration, air drying, and frying; and finally some innovative and practical applications of ultrasound, baking and frying will complete the panorama. Industrial people could use this work as a tool for specific food items or problems, like rheology of some liquid foods, particle distributions of food powders, measurement of cheese texture, approaches for analysis of fouling of heat transfer exchangers, effect of evaporation on food properties; furthermore, they will find recent information and applications of osmotic and air dehydration, combined treatments on fried foods, ultrasound and baking in food processing. Researchers may compare their results with some data presented in tables and graphics included in each chapter.
