This second edition of Water Activity in Foods furnishes those working within food manufacturing, quality control, and safety with a newly revised guide to water activity and its role in the preservation and processing of food items. With clear, instructional prose and illustrations, the book’s international team of contributors break down the essential principles of water activity and water–food interactions, delineating water’s crucial impact upon attributes such as flavor, appearance, texture, and shelf life. The updated and expanded second edition continues to offer an authoritative overview of the subject, while also broadening its scope to include six newly written chapters covering the latest developments in water activity research. Exploring topics ranging from deliquescence to crispness, these insightful new inclusions complement existing content that has been refreshed and reconfigured to support the food industry of today.
Although chemical engineering and food technology are subject areas closely related to food processing systems and food plant design, coverage of the design of food plants is often sporadic and inadequately addressed in food technology and engineering books. Some books have attempted to treat food engineering from this dual point of view but, most
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
Reflecting current trends in alternative food processing and preservation, this reference explores the most recent applications in pulsed electric field (PEF) and high-pressure technologies, food microbiology, and modern thermal and nonthermal operations to prevent the occurrence of food-borne pathogens, extend the shelf-life of foods, and improve
A selected compilation of writings by IUFoST organization supporters, Global Themes in Food Science and Technology were those identified as representing the most important and relevant subjects facing food scientists and technologists today. Chosen by an international editorial board, these subjects offer insights into current research and developments and were selected to stimulate additional interest and work in these key areas.The International Union of Food Science and Technology (IUFoST) is a country-membership organization is the sole global food science and technology organization. It is a voluntary, non-profit association of national food science organizations linking the world's bes...
Completely up-to-date and organized for easy use, this one-of-a-kind reference integrates basic concepts with hands-on techniques for food dehydration. It discusses a wide range of scientific and technical information, from the physical, chemical, and microbiological changes in food dehydration to its packaging aspects.
Nonthermal Processing Technologies for Food offers a comprehensive review of nonthermal processing technologies that are commercial, emerging or over the horizon. In addition to the broad coverage, leading experts in each technology serve as chapter authors to provide depth of coverage. Technologies covered include: physical processes, such as high pressure processing (HPP); electromagnetic processes, such as pulsed electric field (PEF), irradiation, and UV treatment; other nonthermal processes, such as ozone and chlorine dioxide gas phase treatment; and combination processes. Of special interest are chapters that focus on the "pathway to commercialization" for selected emerging technologies where a pathway exists or is clearly identified. These chapters provide examples and case studies of how new and nonthermal processing technologies may be commercialized. Overall, the book provides systematic knowledge to industrial readers, with numerous examples of process design to serve as a reference book. Researchers, professors and upper level students will also find the book a valuable text on the subject.
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 . . . .
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 ...
Preservation of Foods with Pulsed Electric Fields discusses the basics of high voltage PEF as a low temperature food processing method, and the application of this technology in food preservation. This technology is attracting a great deal of interest around the world because it is more cost effective than conventional systems due to the conservative nature of PEF. This book thoroughly covers the electrical and food engineering aspects, as well as the food science components (i.e. food microbiology, enzyme inactivation kinetics, and sensory evaluation). - Fundamentals of high intensity pulsed electric fields - Design of PEF processing equipment - Biological principles for microbial inactivation in electric fields - PEF-induced biological changes - PEF inactivation of vegetable cells, spores, and enzymes in foods - Food processing by PEF - HACCP in PEF processing - PEF in the food industry for the new millennium
