While continuing the tradition of expansive coverage, Fundamentals of Food Process Engineering, Third Edition, has been fully updated and revised. The new edition of this classic text emphasizes problem solving, including technological principles that form the basis for a process so that the process can be better understood and the selection of processing parameters to maximize product quality and safety can be made more effective. In addition, the book contains new, hard-to-find data needed to conduct food process engineering calculations.

New sections reflecting the current state of technology include:

• enthalpy change calculations in freezing based on the freezing point depression

• evaporative cooling

• interpretation of pump performance curves

• determination of shape factors in heat exchange by radiation

• unsteady state heat transfer, kinetic data for thermal degradation of foods during thermal processing

• pasteurization parameters for shelf-stable high acid foods and long-life refrigerated low acid foods

• high pressure processing of fluid and packaged foods

• concentration of juices

• environmentally friendly refrigerants

• modified atmosphere packaging of produce

• sorption equations for water activity of solid foods

• osmotic pressure and water activity relationships

• vacuum dehydration

• new membranes commercially available for food processing and waste treatment

• supercritical fluid extraction

Written for the upper level undergraduate, Fundamentals of Food Process Engineering, Third Edition, is also a solid reference for the graduate food engineering student and professional.

Zusammenfassung
Since the publication of the ?rst edition in 1981 and the second edition in 2001, this textbook has been widely adopted for Food Engineering courses worldwide. The author expresses his gratitude to colleagues who have adopted this textbook and to those who have made constructive criticisms on the material. This new edition not only incorporates changes suggested by colleagues, but additional material has been added to include facilitated problem solving using a computer, and new food processing and food product technologies. New sections have been added in most of the chapters re?ecting the current state of the technology. The expanded coverage may result in not enough time available in a school term to cover all areas; therefore, instructors are advised to carefully peruse the bookandselectthemostappropriatesectionstocoverinaschoolterm. Theadvantageoftheexpanded coverage is the elimination of the need for a supplementary textbook. The success of this textbook has been attributed to the expansive coverage of subject areas speci?ed intheInstituteofFoodTechnologistsmodelcurriculumforfoodsciencemajorsintheUnitedStatesof Americaandtheuseofexamplesutilizingconditionsencounteredinactualfoodprocessingoperations.
