Food Spoilage Microorganisms

The control of microbiological spoilage requires an understanding of a number of factors including the knowledge of possible hazards, their likely occurrence in different products, their physiological properties and the availability and effectiveness of different preventative measures. Food spoilage microorganisms focuses on the control of microbial spoilage and provides an understanding necessary to do this. The first part of this essential new book looks at tools, techniques and methods for the detection and analysis of microbial food spoilage with chapters focussing on analytical methods, predictive modelling and stability and shelf life assessment. The second part tackles the management of microbial food spoilage with particular reference to some of the major food groups where the types of spoilage, the causative microorganisms and methods for control are considered by product type. The following three parts are then dedicated to yeasts, moulds and bacteria in turn, and look in more detail at the major organisms of significance for food spoilage. In each chapter the taxonomy, spoilage characteristics, growth, survival and death characteristics, methods for detection and control options are discussed. Food spoilage microorganisms takes an applied approach to the subject and is an indispensable guide both for the microbiologist and the non-specialist, particularly those whose role involves microbial quality in food processing operations. Looks at tools, techniques and methods for the detection and analysis of microbial food spoilage Discusses the management control of microbial food spoilage Looks in detail at yeasts, moulds and bacteria

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.

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.

The Microbiological Quality of Food: Foodborne Spoilers specifically addresses the role of spoilers in food technology and how they affect the quality of food. Food spoilers represent a great challenge in food quality, determining the shelf-life of many products as they impact consumer acceptability of taste, texture, aroma, and other perceptions. Divided into four sections, the first section defines microbial spoilage of food, with special emphasis on methods for the evaluation of spoiling phenomena and the status of their regulatory framework, examining both existing regulations and possible gaps. The second section examines spoiling microorganisms, covering a range of common spoilage microorganisms, including pseudomonas, yeasts, and molds and spore formers, as well as less-common spoilers, including lactic acid bacteria and specific spoilage organisms in fish. The third section highlights spoiling phenomena within certain food types. Chapters cover dairy, fish, meat, and vegetables, and other products. The final section investigates emerging topics which point to future trends in the research of food spoilers. There is insight into microorganisms resistant to preservation, the role of biofilms in food quality, and the link between food safety and food spoilage, with a special emphasis on certain spoiling microorganisms which could be opportunistic pathogens. Written by an international team of leading authors, this book provides state-of-the-art coverage of this topic, which is essential to the shelf-life and quality of food. Provides in-depth coverage of the different spoilers which cause the deterioration of foods, including less common spoilers not covered in other publications Includes dedicated chapters covering the spoilage of specific products, making this book ideal for those working in the food industry Presents a framework for future research in the area of foodborne spoilers

This book gives an overview of the physiology, health, safety and functional aspects of microorganisms present in food and fermented foods. A particular focus is on the health effects of probiotics and non-dairy functional foods. The book deals also with microbes that cause food spoilage and produce toxins, and the efficiency of edible biofilm in the protection of packaged foods. Several chapters are devoted to the occurrence of Listeria pathogens in various food sources. Further topics are fortified foods, the role of trace elements, and the preservation of food and extension of food shelf life by a variety of measures.

This volume presents a wide range of new approaches aimed at improving the safety and quality of food products and agricultural commodities. Each chapter provides in-depth information on new and emerging food preservation techniques including those relating to decontamination, drying and dehydration, packaging innovations and the use of botanicals as natural preservatives for fresh animal and plant products. The 28 chapters, contributed by an international team of experienced researchers, are presented in five sections, covering: Novel decontamination techniques Novel preservation techniques Active and atmospheric packaging Food packaging Mathematical modelling of food preservation processes Natural preservatives This title will be of great interest to food scientists and engineers based in food manufacturing and in research establishments. It will also be useful to advanced students of food science and technology.

The loss of food due to microbial spoilage has economic consequences for the producers, processors and consumers.Except for sterile foods, all foods harbor microorganisms. Food spoilage stems from the growth of these microorganisms in food or in due to the action of microbial heat-stable enzymes. New marketing trends, the consumer s desire for foods that are not overly processed and preserved, extended shelf-life, and chances of temperature abuse between production and consumption of foods have greatly increased the chances of food spoilage and, in some instances, with new types of microorganisms. The major concerns are the economic loss and wastage of food. New concepts are being studied to reduce contamination as well as control the growth of spoilage microbes in foods.This book includes" Food Microbiology and its Horizons " Basics of Human Nutrition " An Introduction to Microbial Spoilage of Foods " Spoilage of Meat and Meat Products " Spoilage of Poultry and Eggs " Spoilage of Fish and other Seafoods " Spoilage of Dairy Products " Spoilage of Vegetables, Fruits and their Products " Spoilage of Cereal Products " Spoilage of Canned Foods " Spoilage of Frozen Foods " Indicators of Microbial Food Spoilage " Microbiological Testing of FoodThe book should prove to be an useful source of information for the students of food microbiology, food science and technology, food biotechnology, agriculture, horticulture, food and nutrition, hotel and catering management and other food-related courses.
