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.
This long awaited second edition of a popular textbook has a simple and direct approach to the diversity and complexity of food processing. It explains the principles of operations and illustrates them by individual processes. The new edition has been enlarged to include sections on freezing, drying, psychrometry, and a completely new section on mechanical refrigeration. All the units have been converted to SI measure. Each chapter contains unworked examples to help the student gain a grasp of the subject, and although primarily intended for the student food technologist or process engineer, this book will also be useful to technical workers in the food industry
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, in
This book and the accompanying CD incorporates educational materials developed from results obtained from 30 years of research on selected computer applications in food processing. The CD contains software to conduct seventeen virtual experiments representing major food processes. The experiments may be used to augment existing laboratory courses, or as contents of a stand-alone virtual laboratory course in the food science curriculum.
Engineering Principles of Unit Operations in Food Processing, volume 1 in the Woodhead Publishing Series, In Unit Operations and Processing Equipment in the Food Industry series, presents basic principles of food engineering with an emphasis on unit operations, such as heat transfer, mass transfer and fluid mechanics. - Brings new opportunities in the optimization of food processing operations - Thoroughly explores applications of food engineering to food processes - Focuses on unit operations from an engineering viewpoint
This is the latest and most authoritative documentation of current scientific knowledge regarding the health effects of thermal food processing. Authors from all over Europe and the USA provide an international perspective, weighing up the risks and benefits. In addition, the contributors outline those areas where further research is necessary.
Thermal processing remains one of the most important processes in the food industry. Now in its second edition, Thermal Food Processing: New Technologies and Quality Issues continues to explore the latest developments in the field. Assembling the work of a worldwide panel of experts, this volume highlights topics vital to the food industry today and pinpoints the trends in future research and development. Topics discussed include: Thermal properties of foods, including heat capacity, conductivity, diffusivity, and density Heat and mass transfer and related engineering principles, mechanisms, and models The development and application of deterministic heat transfer models for predicting internal product temperatures Modeling thermal processing using artificial neural networks (ANN) and computational fluid dynamics (CFD) Thermal processing of meat, poultry, fish, and dairy products; canned foods; ready meals; and vegetables The effect of ultrahigh temperature (UHT) treatment processing on milk, including the impact on nutrient composition, safety, and organoleptic aspects Ohmic, radio frequency (RF) dialectric, infrared, and pressure-assisted heating pH-assisted thermal processing In addition to updating all content, this second edition includes five new chapters: Thermal Effects in Food Microbiology, Modeling Thermal Microbial Inactivation Kinetics, Thermal Processing of Food and Fruit Juices, Aseptic Processing and Packaging, and Microwave Heating. The final chapter of the book examines systems used in the evaluation of thermal processes and the development of time temperature integrators (TTIs) to ensure the safety of thermally processed food. An up-to-date survey of essential techniques and the science behind them, this volume is a critical reference for food industry professionals.
FROM THE PREFACE The purpose of this laboratory manual is to facilitate the understanding of the most relevant unit operations in food engineering. The first chapter presents information on how to approach laboratory experiments; topics covered include safety, preparing for a laboratory exercise, effectively performing an experiment, properly documenting data, and preparation of laboratory reports. The following eleven chapters cover unit operations centered on food applications: dehydration . . . . , thermal processing, friction losses in pipes, freezing, extrusion, evaporation, and physical separations. These chapters are systematically organized to include the most relevant theoretical background pertaining to each unit operation, the objectives of the laboratory exercise, materials and methods . . ., expected results, examples, questions, and references. The experiments presented have been designed for use with generic equipment to facilitate the adoption of this manual . . . .
