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
Many novel technologies have been proposed in the attempt to improve existing food processing methods. Among emerging nonthermal technologies, high intensity pulsed electric fields (PEF) is appealing due to its short treatment times and reduced heating effects. This book presents information accumulated on PEF during the last 15 years by experienced microbiologists, biochemists, food technologists, and electrical and food engineers.
Pulsed Electric Fields (PEF) is a method used in non-thermal food preservation. Chapter One of this book provides inactivation kinetic models for PEF treatment. Chapter Two discusses PEF in the winemaking process. Chapter Three reviews fruit juice preservation. Chapter Four investigates the effect of amplitude and treatment time of PEF on E. coli in carrot juice. Chapter Five analyzes the contribution of major electrical parameters on PEF treatment of Salmonella typhimurium in grape juice. Chapter Six reviews the effect of PEF on the quality of fresh apple fruits. Chapter Seven examines further potential of PEF treatments for the food industry. Chapter Eight discusses network simulation of the electrical response to PEF of ion-exchange membranes in electrodialysis.
Pulsed Electric Fields (PEF) is one of the nonthermal processing approaches that is receiving considerable attention by scientists, government and the food industry as a potential technique to be fully adopted to process foods at the industrial level. PEF presents a number of advantages including minimal changes to fresh foods, inactivation of a wi
Pulsed electric field (PEF) food processing is a novel, non-thermal preservation method that has the potential to produce foods with excellent sensory and nutritional quality and shelf-life. This important book reviews the current status of the technology, from research into product safety and technology development to issues associated with its commercial implementation.Introductory chapters provide an overview of the process and its history. Part one then discusses the technology of PEF food preservation, with chapters on circuitry and pulse shapes, chamber design and technical and safety requirements. The second part of the book focuses on important product safety and quality issues such as probable mechanisms of microbial inactivation by PEF, adaptation potential of microorganisms treated by this method, toxicological aspects, the impact on food enzymes and shelf life. Chapters in the final part of the book cover topics relating to the commercialisation of the technology, including current and future applications, pitfalls, economic issues and scaling up, and public and regulatory acceptance.Food preservation by pulsed electric fields is a standard reference for all those involved in research into PEF food processing and its commercialisation. - Reviews the current status of PEF technology with an overview of the process and its history - Discusses the technology involved in PEF food preservation - Focuses on important product safety and quality issues such as the impact on food enzymes and shelf life
This book conveys many significant messages for the food engineering and allied professions: the importance of working in multidisciplinary teams, the relevance of developing food engineering based on well-established principles, the benefits of developing the field by bringing together experts from industry, academia and government, and the unparalleled advantage of working as globally as possible in the understanding, development, and applications of food engineering principles. I am delighted to welcome this book to the Series and I am convinced colleagues from all parts of the world will gain great value from it.
Food processing technologies are an essential link in the food chain. These technologies are many and varied, changing in popularity with changing consumption patterns and product popularity. Newer process technologies are also being evolved to provide the added advantages. Conventional and Advanced Food Processing Technologies fuses the practical (application, machinery), theoretical (model, equation) and cutting-edge (recent trends), making it ideal for industrial, academic and reference use. It consists of two sections, one covering conventional or well-established existing processes and the other covering emerging or novel process technologies that are expected to be employed in the near future for the processing of foods in the commercial sector. All are examined in great detail, considering their current and future applications with added examples and the very latest data. Conventional and Advanced Food Processing Technologies is a comprehensive treatment of the current state of knowledge on food processing technology. In its extensive coverage, and the selection of reputed research scientists who have contributed to each topic, this book will be a definitive text in this field for students, food professionals and researchers.
The Handbook of Research on Food Processing and Preservation Technologies is a 5-volume collection that highlights various design, development, and applications of novel and innovative strategies for food processing and preservation. Together, the 5 volumes will prove to be valuable resource for researchers, scientists, students, growers, traders, processors, and others in the food processing industry.
"Written by four experts actively researching alternatives to conventional thermal methods in food preservation. Presents information on traditional and emerging nonthermal food processing technologies in a convenient, single-source volume--offering an incisive view of the latest experimental results, state-of-the-art applications, and new developments in food preservation technology. Furnishes a thorough review of nonthermal techniques such as high hydrostatic pressure, pulsed electric fields, oscillating magnetic fields, light pulses, ionizing irradiation, the use of chemicals and bacteriocins as preservation aids, and combined methods/hurdle technology."
Pulsed Electric Fields to Obtain Healthier and Sustainable Food for Tomorrow illustrates innovative applications derived from the use of pulsed electric fields beyond microbial inactivation. The book begins with an introduction on how pulsed electric fields work and then addresses the impact of pulsed electric fields on bioaccessability/bioavailability and the development of nutraceuticals and food additives. Other sections explore the reduction of contaminants and assess the improvement of industrial process efficiency. A final section explores patents and commercial applications. This book will be a welcomed resource for anyone interested in the technological, physiochemical and nutritional perspectives of product development and the reduction of food toxins and contaminants. The concepts explored in this book could have a profound impact on addressing the concept of "food on demand," a concept that is a top priority in industry.
