Hurdle Technologies: Combination Treatments for Food Stability, Safety and Quality is the first work on hurdle technology in which all aspects, the possibilities and limitations of hurdle technology, are comprehensively outlined and evaluated. World-renowned on the subject, Leistner and Gould were instrumental in the development of the hurdle technology concept and in the last decades have obtained much practical experience in the application of this successful approach in the food industry worldwide.

For centuries man has treated food to prolong its edible life, and nowadays both traditional and modern preservatives are used widely to ensure the satisfactory maintenance of quality and safety of foods. There continues to be increased public concern about the use of food additives, including preservatives, resulting from a perception that some of them may have deleterious effects on health. However, as eating habits have changed with an emphasis on what has been popularly termed a `healthy diet', there is at the same time a concern that reduction in preservative usage could lead to loss of safety and protection from food poisoning. While some preservatives are coming under increasing regulatory pressure others, particularly more natural ones, are receiving increased attention and gaining in importance and acceptability.This book supports the continued safe and effective use of preservatives within these current constraints. It therefore gives detailed information on the practical use of the major antimicrobial preservatives. Uniquely, it couples this with current understanding of their modes of action, at the levels of cellular physiology and biochemistry, in such a way as to provide a sound scientific basis for their efficacy. Such an approach also encourages the future logical development and use of preservatives.

The food world has a number of options available to make the food industry more diverse, competitive, and efficient. Innovations in Food Processing investigates some of these options, alternative technologies, and strategies for properly addressing new challenges facing the food industry. It also provides specific examples on how these alternatives can be utilized in specific food products.This book presents a comprehensive review of new technologies to preserve foods, especially those based on nonthermal techniques. It covers a wide range of methods, including high pressure, pulsed electric fields, and hurdle technologies. Other chapters include information about the trends in emerging technologies over the past 40 years and predictive models that describe microbial growth. Expert contributors present thorough research results and critical reviews of each covered technology. The innovative approaches presented in Innovations in Food Processing will result in sound alternatives for addressing the ever-increasing demand for quality foods at a reasonable cost.

This authoritative two-volume reference provides valuable, necessary information on the principles underlying the production of microbiologically safe and stable foods. The work begins with an overview and then addresses four major areas: 'Principles and application of food preservation techniques' covers the specific techniques that defeat growth of harmful microorganisms, how those techniques work, how they are used, and how their effectiveness is measured. 'Microbial ecology of different types of food' provides a food-by-food accounting of food composition, naturally occurring microflora, effects of processing, how spoiling can occur, and preservation. 'Foodborne pathogens' profiles the most important and the most dangerous microorganisms that can be found in foods, including bacteria, viruses, parasites, mycotoxins, and 'mad cow disease.' The section also looks at the economic aspects and long-term consequences of foodborne disease. 'Assurance of the microbiological safety and quality of foods' scrutinizes all aspects of quality assurance, including HACCP, hygienic factory design, methods of detecting organisms, risk assessment, legislation, and the design and accreditation of food microbiology laboratories. Tables, photographs, illustrations, chapter-by-chapter references, and a thorough index complete each volume. This reference is of value to all academic, research, industrial and laboratory libraries supporting food programs; and all institutions involved in food safety, microbiology and food microbiology, quality assurance and assessment, food legislation, and generally food science and technology.

This book describes in detail those new and emerging food preservation techniques that are now, or soon will be, commerically exploited. The editor, a leading figure in this field, has assembled a team of well-known and respected contributors, who cover chemical, biological and physically based-approaches. Emphasis is placed both on the innovative exploitation of traditional procedures, including combination preservation methods, and on more radical approaches, such as the use of high hydrostatic pressures or voltage pulses to inactivate microorganisms in food, and the direct and synergistic application of ultrasonic radiation.
