Microbial Stress Adaptation and Food Safety


Book Description

The first book to address the subject, Microbial Stress Adaptation and Food Safety emphasizes the implications of stress adaptation and its consequences for food safety. It covers the basic science, kinetics, mechanisms, assessment, and control of stress adaptation and its impact on the safety of foods produced by minimal processing or non-thermal technologies. World renowned experts in the field provide detailed accounts of problems associated with stress adaptation and suggest methods for overcoming these problems. The book begins with an introduction to the stress adaptation phenomenon and its implications for the safety of food processed by novel technologies. Then it addresses the responses of pathogens to physical and chemical stresses encountered during food processing, such as heat, pressure, dehydration, radiation, added organic acids, and naturally occurring antimicrobials. The adaptation of food microbiota to stress as a survival strategy is covered next, followed by an examination of the broad spectrum of stresses that may increase a pathogen's tenacity and resistance to processing. Other topics include stress adaptation of beneficial lactic acid bacteria and how resistance or adaptation to stress in the processing environment relates to pathogens' ability to cause disease. Finally, the book presents strategies to overcome stress adaptation in foodborne pathogens. The authors suggest practical control measures and emphasize the need for future research to counteract the stress adaptation phenomenon. Microbial Stress Adaptation and Food Safety proposes practical solutions to microbial stress adaptation and its hazardous effects on food safety and human health.




Quantitative Microbiology in Food Processing


Book Description

Microorganisms are essential for the production of many foods, including cheese, yoghurt, and bread, but they can also cause spoilage and diseases. Quantitative Microbiology of Food Processing: Modeling the Microbial Ecology explores the effects of food processing techniques on these microorganisms, the microbial ecology of food, and the surrounding issues concerning contemporary food safety and stability. Whilst literature has been written on these separate topics, this book seamlessly integrates all these concepts in a unique and comprehensive guide. Each chapter includes background information regarding a specific unit operation, discussion of quantitative aspects, and examples of food processes in which the unit operation plays a major role in microbial safety. This is the perfect text for those seeking to understand the quantitative effects of unit operations and beyond on the fate of foodborne microorganisms in different foods. Quantitative Microbiology of Food Processing is an invaluable resource for students, scientists, and professionals of both food engineering and food microbiology.

Advances in microbial food safety


Book Description

This chapter discusses the research on the use of organic acids as decontamination agents for foods of animal and plant origin. First, the application of organic acids to meat decontamination (i.e., carcasses and trimmings) is presented followed by an overview of research into the use of organic acids for decontaminating vegetables, fruits and fruit juices. Both single and multiple interventions are discussed. Then, the potential concerns of microbial adaptation to acid treatments are examined and the current legislation status at international level is presented. Key points and practical implications for the industry are discussed in the final section of the chapter.




Microbiology of Fruits and Vegetables


Book Description

Microbiology of Fruits and Vegetables presents a holistic view of the problem of produce contamination that examines both pre-harvest and post-harvest sources and practices. It addresses a number of topical issues relating to the microbiological quality and safety of fresh and processed fruits and vegetables and explores the linkage between microbial attachment, the state of microbial contaminants on produce surfaces, and the problem of decontamination. This volume focuses on five distinct areas, and within these areas, provides in-depth coverage of scientific issues important to an understanding of the field and technical issues of economic and public health significance.

Industrial and Host Associated Stress Responses in Food Microbes. Implications for Food Technology and Food Safety


Book Description

Throughout the food processing chain and after ingestion by the host, food associated bacteria have to cope with a range of stress factors such as thermal and/or non-thermal inactivation treatments, refrigeration temperatures, freeze-drying, high osmolarity, acid pH in the stomach or presence of bile salts in the intestine, that threaten bacterial survival. The accompanying plethora of microbial response and adaptation phenomena elicited by these stresses has important implications for food technology and safety. Indeed, while resistance development of pathogenic and spoilage microorganisms may impose health risks for the consumer and impart great economic losses to food industries, reduced survival of probiotic bacteria may strongly compromise their claimed health benefit attributes. As a result, substantial research efforts have been devoted in the last decades to unravel the mechanisms underlying stress response and resistance development in food associated microorganisms in order to better predict and improve (i) the inactivation of foodborne pathogens and spoilage microorganisms on the one hand and (ii) the robustness and performance of beneficial microorganisms on the other. Moreover, the recent implementation of system-wide omics and (single-)cell biology approaches is greatly boosting our insights into the modes of action underlying microbial inactivation and survival. This Research Topic aims to provide an avenue for dissemination of recent advances within the field of microbial stress response and adaptation, with a particular focus not only on food spoilage and pathogenic microorganisms but also on beneficial microbes in foods.
