In order to successfully produce food products with maximum quality, each stage of processing must be well-designed. Unit Operations in Food Engineering systematically presents the basic information necessary to design food processes and the equipment needed to carry them out. It covers the most common food engineering unit operations in detail, including guidance for carrying out specific design calculations. Initial chapters present transport phenomena basics for momentum, mass, and energy transfer in different unit operations. Later chapters present detailed unit operation descriptions based on fluid transport and heat and mass transfer. Every chapter concludes with a series of solved problems as examples of applied theory.

Packed with case studies and problem calculations, Handbook of Food Processing: Food Preservation presents the information necessary to design food processing operations and goes on to describe the equipment needed to carry them out in detail. The book covers every step in the sequence of converting raw material to the final product. It also discusses the most common food engineering unit operations and food preservation processes, such as blanching, pasteurization, chilling, and freezing to aseptic packaging, non-thermal food processing, and the use of biosensors. Highlights Include Case study on the effect of blanching conditions on sulforaphane content in purple and roman cauliflower (brassica oleracea l. Var. Botrytis) Principles of thermal processing described along with thermal process calculations Case study on microwave preservation of fruit-based products: application to kiwifruit puree Principles and applications of Ohmic heating Advances in food additives and contaminants Use of edible films and coatings in fresh fruits and vegetables preservation The book provides information regarding the common food preservation methods such as blanching, thermal processing of foods, canning, extrusion-cooking, drying or dehydration of foods, chilling, and freezing. It also describes the principles and applications of new thermal and non-thermal food processing technologies, i.e., microwave heating, ohmic heating, high pressure (HP) processing, pulsed electric field (PEF) processing, magnetic fields, ultrasound, use of edible films and coatings, food packaging-aseptic packaging, and modified atmosphere, biosensor and ozone applications. The book helps you keep up with diverse consumer demands and rapidly developing markets.

In chemical engineering and related fields, a unit operation is a basic step in a process. For example in milk processing, homogenization, pasteurization, chilling, and packaging are each unit operations which are connected to create the overall process. A process may have many unit operations to obtain the desired product. The book will cover many different unit operations as they apply to food processing.

The first edition of Food Processing Technology was quickly adopted as the standard text by many food science and technology courses. While keeping with the practice of covering the wide range of food processing techniques, this new edition has been substantially expanded to take account of the advances in technology that have taken place since the publication of the first edition. The Second Edition includes new chapters on computer control of processing, novel 'minimal' technologies, and Ohmic heating, and an extended chapter on modified atmosphere packaging. It is a comprehensive - yet basic - text that offers an overview of most unit operations, while at the same time providing details of the processing equipment, operating conditions and the effects of processing on the biochemistry of foods. The book is divided into five parts, in which unit operations are grouped according to the nature of the heat transfer that takes place. Each chapter describes the formulae required for calculation of processing parameters, sample problems, and the effects on sensory characteristics and nutritional properties of selected foods. By combining food processing theory and calculations with descriptions of commercial practice and results of scientific studies, Food Processing Technology: Principles and Practice, Second Edition helps readers make attractive saleable products and extend the shelf-life of foods.

Consumer expectations are systematically growing, with demands for foods with a number of attributes, which are sometimes difficult for manufacturers to meet. The engineering processes that are needed to obtain top-quality foods are a major challenge due to the diversity of raw materials, intermediates, and final products. As in any other enterprise, the food industry must optimize each of the steps in the production chain to attain the best possible results. There is no question that a very important aspect to take into consideration when developing a process, designing a food factory, or modifying existing facilities is the in-depth knowledge of the basic engineering aspects involved in a given project. Introduction to Food Process Engineering covers the fundamental principles necessary to study, understand, and analyze most unit operations in the food engineering domain. It was conceived with two clear objectives in mind: 1) to present all of the subjects in a systematic, coherent, and sequential fashion in order to provide an excellent knowledge base for a number of conventional and unconventional processes encountered in food industry processing lines, as well as novel processes at the research and development stages; 2) to be the best grounding possible for another CRC Press publication, Unit Operations in Food Engineering, Second Edition, by the same authors. These two books can be consulted independently, but at the same time, there is a significant and welcomed match between the two in terms of terminology, definitions, units, symbols, and nomenclature. Highlights of the book include: Dimensional analysis and similarities Physicochemistry of food systems Heat and mass transfer in food Food rheology Physical properties Water activity Thermal processing Chilling and freezing Evaporation Dehydration Extensive examples, problems, and solutions

A unique and interdisciplinary field, food processing must meet basic process engineering considerations such as material and energy balances, as well as the more specialized requirements of food acceptance, human nutrition, and food safety. Food engineering, therefore, is a field of major concern to university departments of food science, and chemical and biological engineering as well as engineers and scientists working in various food processing industries. Part of the notable CRC Press Contemporary Food Engineering series, Food Process Engineering Operations focuses on the application of chemical engineering unit operations to the handling, processing, packaging, and distribution of food products. Chapters 1 through 5 open the text with a review of the fundamentals of process engineering and food processing technology, with typical examples of food process applications. The body of the book then covers food process engineering operations in detail, including theory, process equipment, engineering operations, and application examples and problems. Based on the authors’ long teaching and research experience both in the US and Greece, this highly accessible textbook employs simple diagrams to illustrate the mechanism of each operation and the main components of the process equipment. It uses simplified calculations requiring only elementary calculus and offers realistic values of food engineering properties taken from the published literature and the authors’ experience. The appendix contains useful engineering data for process calculations, such as steam tables, engineering properties, engineering diagrams, and suppliers of process equipment. Designed as a one or two semester textbook for food science students, Food Process Engineering Operations examines the applications of process engineering fundamentals to food processing technology making it an important reference for students of chemical and biological engineering interested in food engineering, and for scientists, engineers, and technologists working in food processing industries.
