Microbiology Of Fruits And Vegetables

Fresh and fresh-cut fruits and vegetables have an excellent safety record. However, surveillance data from the U.S. Centers for Disease Control and Prevention and recent foodborne illness outbreaks have demonstrated that the incidence of foodborne illnesses linked to the consumption of contaminated fresh fruit and vegetable products may in fact be

The increased emphasis on food safety during the past two decades has decreased the emphasis on the loss of food through spoilage, particularly in developed co- tries where food is more abundant. In these countries spoilage is a commercial issue that affects the pro?t or loss of producers and manufacturers. In lesser developed countries spoilage continues to be a major concern. The amount of food lost to spoilage is not known. As will be evident in this text, stability and the type of spoilage are in?uenced by the inherent properties of the food and many other factors. During the Second World War a major effort was given to developing the te- nologies needed to ship foods to different regions of the world without spoilage. The food was essential to the military and to populations in countries that could not provide for themselves. Since then, progress has been made in improved product formulations, processing, packaging, and distribution systems. New products have continued to evolve, but for many new perishable foods product stability continues to be a limiting factor. Many new products have failed to reach the marketplace because of spoilage issues.

This book covers application of food microbiology principles into food preservation and processing. Main aspects of the food preservation techniques, alternative food preservation techniques, role of microorganisms in food processing and their positive and negative features are covered. Features subjects on mechanism of antimicrobial action of heat, thermal process, mechanisms for microbial control by low temperature, mechanism of food preservation, control of microorganisms and mycotoxin formation by reducing water activity, food preservation by additives and biocontrol, food preservation by modified atmosphere, alternative food processing techniques, and traditional fermented products processing. The book is designed for students in food engineering, health science, food science, agricultural engineering, food technology, nutrition and dietetic, biological sciences and biotechnology fields. It will also be valuable to researchers, teachers and practising food microbiologists as well as anyone interested in different branches of food.

Presents the latest research and industry practices promoting microbiological safety of fruits and vegetables. - Examines key issues of microbiological safety of fresh produce, from production to consumption, and focuses on the unique challenges the specialists encounter in controlling microorganisms found on produce. - Highlights microorganisms associated with human illness and linked to consumption of contaminated produce. - Discusses industry trends and topical issues, including the microbiology of imported and domestic produce, good agricultural practices, irradiation, edible films, and diagnostic techniques used in the field. - Features a chapter devoted to the practices related to the safety of seed sprouts, covering valuable information relevant to the producer, researcher, and extension specialist.

Fresh-cut Fruits and Vegetables: Science, Technology, and Market provides a comprehensive reference source for the emerging fresh-cut fruits and vegetables industry. It focuses on the unique biochemical, physiological, microbiological, and quality changes in fresh-cut processing and storage and on the distinct equipment design, packaging requirements, production economics, and marketing considerations for fresh-cut products. Based on the extensive research in this area during the past 10 years, this reference is the first to cover the complete spectrum of science, technology, and marketing issues related to this field, including production, processing, physiology, biochemistry, microbiology, safety, engineering, sensory, biotechnology, and economics.

Food safety regulators face a daunting task: crafting food safety performance standards and systems that continue in the tradition of using the best available science to protect the health of the American public, while working within an increasingly antiquated and fragmented regulatory framework. Current food safety standards have been set over a period of years and under diverse circumstances, based on a host of scientific, legal, and practical constraints. Scientific Criteria to Ensure Safe Food lays the groundwork for creating new regulations that are consistent, reliable, and ensure the best protection for the health of American consumers. This book addresses the biggest concerns in food safetyâ€"including microbial disease surveillance plans, tools for establishing food safety criteria, and issues specific to meat, dairy, poultry, seafood, and produce. It provides a candid analysis of the problems with the current system, and outlines the major components of the task at hand: creating workable, streamlined food safety standards and practices.

Problems linked with pathogens in fresh produce, including the associated public health and trade implications, have been reported in a number of countries worldwide. Furthermore, from 1980 to 2004, the global production per annum of fruit and vegetables grew by 94% and fruit and vegetables are a critical component of a healthy diet. Thus, ensuring the safety of these products is of high importance. Reported outbreaks associated with leafy vegetables and herbs have been notable for the wide geographical distribution of the contaminated products, the high numbers of consumers exposed and thus the large number of cases. This meeting addressed the pathways for contamination, survival and persistence of microbiological hazards associated with leafy vegetables and herbs, and the potential management options from primary production through to the consumer. Consideration was given to all aspects of the farm to fork continuum, i.e. pre-harvest and post-harvest.

Food Spoilage Microorganisms: Ecology and Control focuses on the occurrence, outbreak, consequences, control, and evaluation of spoilage microorganisms in food, providing the necessary basic knowledge of food spoilage ecology and control so as to ensure food safety, especially in developing countries where food hygiene in storage requires special care. The first part of the book looks at spoilage microorganisms in plant origin foods, such as cereals, beans, fruits, and vegetables, and the second part tackles the spoilage microorganisms in animal origin foods like meat, poultry, seafood, powdered milk, and egg products. In each chapter, the taxonomy of spoilage microorganisms, spoilage characteristics, consequences and possible mechanisms, and specific methods for detection and evaluation are discussed based on the basis surface introduction. The control, prevention, and management options for spoilage microorganisms are also presented. In addition, opportunities and challenges are summarized and predicted in the last part of each chapter.
