In addition, Microbiology in Dairy Processing covers the Lactic Acid Bacteria and dairy associated species (the beneficial microorganisms used in food fermentation processes): culture methods, phenotyping, and proven applications in dairy and non-dairy productions. The text also reviews the potential future exploitation of the culture of novel strains with useful traits such as probiotics, fermentation of sugars, metabolites produced, bacteriocins. This important resource: Offers solutions both established and novel to the numerous challenges commonly encountered in the industrial processing of milk and the production of milk products Takes a highly practical approach, tackling the problems faced in the workplace by dairy technologists Covers the whole chain of dairy processing from milk collection and storage though processing and the production of various cheese types Written for laboratory technicians and researchers, students learning the protocols for LAB isolation and characterisation, Microbiology in Dairy Processing is the authoritative reference for professionals and students.

Throughout the world, milk and milk products are indispensablecomponents of the food chain. Not only do individual consumers useliquid milk for beverages and cooking, but food manufacturers usevast quantities of milk powder, concentrated milks, butter, andcream as raw materials for further processing. Effective qualityassurance in the dairy industry is needed now more than ever. Thiscompletely revised and expanded Third Edition of Dairy MicrobiologyHandbook, comprising both Volume I: Microbiology of Milk and VolumeII: Microbiology of Milk Products, updates the discipline’sauthoritative text with the latest safety research, guidelines, andinformation. Pathogens have become a major issue in dairy manufacturing.Escheria coli is a concern, and milk-borne strains of Mycobacteriumavium sub-sp. paratuberculosis have been identified as a possiblecause of Crohn’s disease. Even little-known parasites likeCryptosporidium have caused disease outbreaks. Consequently, ahazard analysis of selected control/critical points (HACCP) in anymanufacturing process has become essential to prevent thecontamination of food. This volume also: -Discusses new diagnostic techniques that allow a pathogen to bedetected in a retail sample in a matter of hours rather thandays -Provides thorough coverage of dairy microbiology principles aswell as practical applications -Includes the latest developments in dairy starter cultures andgenetic engineering techniques -Offers completely updated standards for Good ManufacturingPractice Quality control and product development managers,microbiologists, dairy scientists, engineers, and graduate studentswill find the Third Edition of Dairy Microbiology Handbook to be avital resource.

The objective of this book is to provide a scientific background to dairy microbiology by re-examining the basic concepts of general food microbiology and the microbiology of raw milk while offering a practical approach to the following aspects: well-known and newfound pathogens that are of major concern to the dairy industry. Topics addressed incl

This book covers recent developments in types, classifications, and genetic traits of indigenous milk microorganisms and dairy starter cultures. It also discusses biochemical reactions taking place in different dairy products and microorganisms involved in such reactions. The text provides strategies for rapid detection of pathogenic and non‐pathogenic organisms in milk and milk products and safety systems for dairy processing. It concludes with a discussion of the effects of non‐thermal processing technologies on milk microorganisms and biochemical reactions in milk products.

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.

In recent years, the formation and impacts of biofilms on dairy manufacturing have been studied extensively, from the effects of microbial enzymes produced during transportation of raw milk to the mechanisms of biofilm formation by thermophilic spore-forming bacteria. The dairy industry now has a better understanding of biofilms and of approaches that may be adopted to reduce the impacts that biofilms have on manufacturing efficiencies and the quality of dairy products. Biofilms in the Dairy Industry provides a comprehensive overview of biofilm-related issues facing the dairy sector. The book is a cornerstone for a better understanding of the current science and of ways to reduce the occurrence of biofilms associated with dairy manufacturing. The introductory section covers the definition and basic concepts of biofilm formation and development, and provides an overview of problems caused by the occurrence of biofilms along the dairy manufacturing chain. The second section of the book focuses on specific biofilm-related issues, including the quality of raw milk influenced by biofilms, biofilm formation by thermoduric streptococci and thermophilic spore-forming bacteria in dairy manufacturing plants, the presence of pathogens in biofilms, and biofilms associated with dairy waste effluent. The final section of the book looks at the application of modelling approaches to control biofilms. Potential solutions for reducing contamination throughout the dairy manufacturing chain are also presented. Essential to professionals in the global dairy sector, Biofilms in the Dairy Industry will be of great interest to anyone in the food and beverage, academic and government sectors. This text is specifically targeted at dairy professionals who aim to improve the quality and consistency of dairy products and improve the efficiency of dairy product manufacture through optimizing the use of dairy manufacturing plant and reducing operating costs.

Fermented dairy products represent one of the oldest forms of biotechnology practice by mankind. Essential to this process is the growth and development of a highly specialised and specifically selected group of microbes collectively known as Lactic Acid Bacteria (LAB) that bring about the bioconversion of milk to one of a myriad of unique fermented dairy foods. Today, the economic value of the global dairy industry is estimated in the billions and is dependent on the consistent and reliable activity of LAB. Through the chapters of this book, experts in the field describe the basic biology and genetics of LAB phage providing a basis of understanding for their impact on the dairy fermentation process..

This book focuses on advanced research and technologies in dairy processing, one of the most important branches of the food industry. It addresses various topics, ranging from the basics of dairy technology to the opportunities and challenges in the industry. Following an introduction to dairy processing, the book takes readers through various aspects of dairy engineering, such as dairy-based peptides, novel milk products and bio-fortification. It also describes the essential role of microorganisms in the industry and ways to detect them, as well as the use of prebiotics, and food safety. Lastly, the book examines the challenges faced, especially in terms of maintaining quality across the supply chain. Covering all significant areas of dairy science and processing, this interesting and informative book is a valuable resource for post-graduate students, research scholars and industry experts.
