The safety and efficacy of minimal food processing depends on the use of novel preservation technologies. This book first examines what is meant by minimally processed foods, including fresh-cut, cooked-chilled, and part-baked products. Next explored are the technologies or methods to produce quality products in terms of safety and nutrition, including: edible coating, natural preservatives (i.e., antimicrobial, flavour enhancer, anti-browning), advanced packaging (active, antimicrobial, and modified or controlled atmosphere), and selected non-thermal techniques (high pressure, pulsed electric field, ultrasound, light). Preservation of food is crucial to achieving a secure and safe global food supply with the desired sensory quality. In addition, the increasing consumer demand for safe, ready-to-serve, ready-to-eat-and-cook products with minimal chemical preservatives has raised expectations. However, foods deemed minimally processed, such as fresh-cut fruits and vegetables, cooked-chilled, and half-baked foods, are delicate products that need special care in preparation, processing, storage, and handling. As a result, new technologies to develop minimally processed foods have aggressively advanced. Minimally Processed Foods: Technologies for Safety, Quality, and Convenience explores both the definition of minimally processed foods and the methods and technologies used to achieve the safety and nutritional value consumers demand.

A comprehensive review of the many new developments in the growing food processing and packaging field Revised and updated for the first time in a decade, this book discusses packaging implications for recent nonthermal processing technologies and mild food preservation such as high pressure processing, irradiation, pulsed electric fields, microwave sterilization, and other hurdle technologies. It reviews typical nonthermal processes, the characteristics of food products after nonthermal treatments, and packaging parameters to preserve the quality and enhance the safety of the products. In addition, the critical role played by packaging materials during the development of a new nonthermal processed product, and how the package is used to make the product attractive to consumers, is discussed. Packaging for Nonthermal Processing of Food, Second Edition provides up to date assessments of consumer attitudes to nonthermal processes and novel packaging (both in the U.S. and Europe). It offers a brand new chapter covering smart packaging, including thermal, microbial, chemical, and light sensing biosensors, radio frequency identification systems, and self-heating and cooling packaging. There is also a new chapter providing an overview of packaging laws and regulations in the United States and Europe. Covers the packaging types required for all major nonthermal technologies, including high pressure processing, pulsed electric field, irradiation, ohmic heating, and others Features a brand new chapter on smart packaging, including biosensors (thermal-, microbial-, chemical- and light-sensing), radio frequency identification systems, and self-heating and cooling packaging Additional chapters look at the current regulatory scene in the U.S. and Europe, as well as consumer attitudes to these novel technologies Editors and contributors bring a valuable mix of industry and research experience Packaging for Nonthermal Processing of Food, Second Edition offers many benefits to the food industry by providing practical information on the relationship between new processes and packaging materials, to academia as a source of fundamental knowledge about packaging science, and to regulatory agencies as an avenue for acquiring a deeper understanding of the packaging requirements for new processes.
The progress that has been made over the last decade in the preparation, development, processing, and marketing of food has to a large extent been made possible by innovations and developments in the ways that thermo plastics, in conjunction with paper, metal foils, adhesives and other materials, have been combined and formed into the appropriate configurations to provide the properties required. Much has been said, written and published about retort pouches, modified atmosphere packaging and aseptic preservation processes, and even more about the newer methods of distribution and retailing of all kinds of food. However, all of this material needed to be digested, condensed into a logical framework and appraised, and possible further developments considered. In many instances, the original research and development was carried out in conjunction with one or more of the research organisations in membership with IAPRI, the International Association of Packaging Research Institutes, and it was felt that a book which attempted to provide a review of the more important developments would be useful to practitioner and student alike.
Publications in food technology proliferate; however, noticeable by its absence of coverage is the subject of processing and packaging of particulates in foods. Recent years have seen significant advances which will almost certainly result in substitution of existing and conventional retorting. In addition, when com bined with high temperature/short time (HTST) processing, we can expect substantial further growth, reflecting quality and convenience advantages over products processed from yesterday's technologies. The anticipated growth in particulates is driven by both materials and packaging advances and only requires modest marketing of the organoleptic advantages to establish their place on menu options. The directions taken in packaging developments, especially those interfacing with the latest and established methods of processing, are increasingly influ enced by the need to design packaging on a cradle-to-grave basis. Time was when multi-laminated films on board satisfied the total needs of consumers of aseptic products. The problems of recycling combustible, i.e. energy generating mate rials laminated with aluminium foil, are becoming sensitive issues in a world preoccupied with recycling, and are creating openings for alternative and envi ronmentally friendly material combinations. This book brings together advanced technologies in the field, to provide information for professionals with interests in aseptic processing on how to go about selecting a system appropriate to their commercial needs and constraints.
It has become popular to blame the American obesity epidemic and many other health-related problems on processed food. Many of these criticisms are valid for some processed-food items, but many statements are overgeneralizations that unfairly target a wide range products that contribute to our health and well-being. In addition, many of the proposed dangers allegedly posed by eating processed food are exaggerations based on highly selective views of experimental studies. We crave simple answers to our questions about food, but the science behind the proclamations of food pundits is not nearly as clear as they would have you believe. This book presents a more nuanced view of the benefits and limitations of food processing and exposes some of the tricks both Big Food and its critics use to manipulate us to adopt their point of view. Food is a source of enjoyment, a part of our cultural heritage, a vital ingredient in maintaining health, and an expression of personal choice. We need to make those choices based on credible information and not be beguiled by the sophisticated marketing tools of Big Food nor the ideological appeals and gut feelings of self-appointed food gurus who have little or no background in nutrition.
