The third part includes six chapters treating subjects related with pressure in containers, simultaneous sterilization and thermal food processing equipment. The fourth part includes four chapters including computational fluid dynamics and multi-objective optimization. The fifth part, entitled Innovative Thermal Food Processing, includes a chapter focused on two innovative processes used for food sterilization such high pressure with thermal sterilization and ohmic heating. Thermal Processing of Pa ckaged Foods, Third Edition is intended for a broad audience, from undergraduate to post graduate students, scientists, engineers and professionals working for the food industry.

This is the second edition of Holdsworth and Simpson’s highly practical work on a subject of growing importance in this age of convenience foods. As before, it discusses the physical and engineering aspects of the thermal processing of packaged foods, and examines the methods which have been used to establish the time and temperature of processes to sterilize or pasteurize the food. However, there is lots of new material too. Unlike other texts on thermal processing, which cover very adequately the technology of the subject, the unique emphasis of this text is on processing engineering and its relation to the safety of processed foods products.

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 an

The newly revised Second Edition of Essentials of Thermal Processing delivers a thorough reference on the science and applications of the thermal processing of a wide variety of food products. The book offers readers essential information on the preservation of food products by heat, including high-acid foods and low-acid sterilized foods requiring a full botulinum cook. The accomplished authors—noted experts in their field—discuss all relevant manufacturing steps, from raw material microbiology through the various processing regimes, validation methods, packaging, incubation testing, and spoilage incidents. Two new chapters on temperature and heat distribution, as well as heat penetration of foods, are included. More worked and practical examples are found throughout the book as well. Readers will also benefit from the inclusion of: A thorough introduction to the microbiology of heat processed foods, food preservation techniques, low acid canned foods, and high acid foods An exploration of acidified products, heat extended shelf-life chilled foods, and processing methods Discussions of cooking and process optimization, process validation, and heat penetration and process calculations An examination of cooling and water treatment, how to handle process deviations, and packaging options for heat preserved foods Perfect for professionals working in the food processing and preservation industries, Essentials of Thermal Processing will also earn a place in the libraries of anyone seeking a one-stop reference on the subject of thermal processing for food products.

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.

The application of heat is both an important method of preserving foods and a means of developing texture, flavour and colour. It has long been recognised that thermal technologies must ensure the safety of food without compromising food quality. Improving the thermal processing of foods summarises key research both on improving particular thermal processing techniques and measuring their effectiveness. Part one examines how best to optimise thermal processes, with chapters addressing safety and quality, efficiency and productivity and the application of computational fluid dynamics. Part two focuses on developments in technologies for sterilisation and pasteurisation with chapters on modelling retort temperature control and developments in packaging, sous-vide and cook-chill processing. There are chapters covering continuous heat processing, including developments in tubular heat exchangers, aseptic processing and ohmic and air impingement heating. The fourth part considers the validation of thermal processes, modelling heat penetration curves, using data loggers and time-temperature integrators and other new measuring techniques. The final group of chapters detail methods of analysing microbial inactivation in thermal processing and identifying and dealing with heat-resistant bacteria. Improving the thermal processing of foods is a standard reference book for those working in the food processing industry. Concisely explores prevailing developments in thermal technologies Summarises key research for improving food preservation techniques Analyses the effectiveness of methods used to enhance the quality of food

Publications concerned with the heat processing of foods stress the importance of factory management and operatives strictly complying with scheduled heat processes, but there is limited coverage in technical publications of the details of procedures for monitoring heat transfer in products and the many considerations which must be taken into account to avoid errors. The personnel required to carry out heat penetration trials often do not have access to practical information on this subject.Decisions on heat processing regimes are required for all new products, as well those in which there has been a change in formulation, manufacturing procedures or packaging type or shape. Routine checks on established lines are also good practice. This guideline addresses these issues, by focusing on the selection of heat process values, heat transfer characteristics, methods of evaluating processes and critical factors to consider when developing a heat processing regime. It is primarily aimed at in-pack (metal, glass or plastic) sterilised foods and drinks (both high- and low-acid), but many aspects can also be applied to pasteurised products. It will serve as a vital source of information for staff with limited experience of this type of work, and as a useful reference document for more experienced operatives.

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.
