The use of microorganisms and their metabolites for the preservation of foods began in prehistory. Lactic acid bacteria are generally recognized as safe (GRAS) for this purpose. They produce organic acids, diacetyl, acetoin, hydrogen peroxide, reuterin, reutericyclin and bacteriocins, all of which inhibit foodborne pathogens and spoilage microorganisms. Bacteriocins and the strains that produce them are particularly effective as bio-preservatives in cheese, meat and vegetables. They hold the promise of ensuring the quality and safety of ready-to-eat, extended-shelf-life, fresh-tasting and minimally processed foods without chemical preservatives. This Research Topic provides an overview of bacterial cultures, bacteriocins and other metabolites that have shown promise for use as antimicrobial bio-preservatives in foods in general. Articles describing novel analytical technologies, strategies to reduce or eliminate pathogens in food systems or emerging technologies for the production or use of protective cultures or their bacteriocins are presented.

Consumers favour foods with fewer synthetic additives, but products must also be safe to eat and have a sufficiently long shelf-life. Biopreservation, the use of a product’s natural microflora and its antibacterial products for protection against pathogens and spoilage, is a method of growing interest for the safe production of high quality minimally-processed foods. This book provides an essential overview of key topics in this area.Initial chapters review central aspects in food biopreservation, including the identification of new protective cultures and antimicrobial culture components, existing commercial fermentates including nisin and natamycin and the potential of novel fermentates and bacteriophages to improve food safety. Part II concentrates on the use of protective cultures, bacteriocins and bacteriophages to control the carriage of pathogenic microorganisms in food animals and to modulate human gut microflora. Chapters in the final section of the book review biopreservation of different types of foods, including milk and dairy products, fermented meats, fresh seafood and fruit. A review of active packaging for food biopreservation completes the volume.Edited by a leading expert, Protective cultures, antimicrobial metabolites and bacteriophages for food and beverage biopreservation is a fundamental reference for researchers and food industry professionals working to ensure the safety of the food supply. Reviews the central aspects in food biopreservation, including the identification of new protective cultures and antimicrobial culture components Examines the use of protective cultures, bacteriocins and bacteriophages to control the carriage of pathogenic microorganisms Provides an overview of the biopreservation of different types of foods, including milk and dairy products, fermented meats, fresh seafood and fruit

Bacteriocins are a heterogeneous group of peptides or proteins with antimicrobial activity synthesised ribosomally and released extracellularly by bacteria belonging to nearly all taxonomic groups. These are classified according to their genetic, structural and biochemical characteristics. Use of bacteriocinogenic cultures to improve the safety of food products would represent an attractive alternative to the use of chemical preservatives, based on the long history of safe use of naturally occurring bacteriocin producing food-grade bacteria. Chapter One in this book discusses the effects of bacteriocin production in situ by bacteria in food products and evidence for the probiotic properties of bacteriocin producers are collected in order to identify processes in which the application of bacteriocinogenic cultures can be effectively implemented. Chapter Two examines the importance of the use of bacteriocins in food preservation and also their potential use in human health. Chapter Three discusses a broad range of bacteriocin applications focusing not only on food biopreservation but also on biofilm control. Chapter Four reviews the recent applications of bacteriocin-producing PC in meats and meat products throughout the world. Chapter Five evaluates the effect of mild pressure treatments in the survival of Pediococcus acidilactici HA-6111-2 and on its bacteriocin production capacity.

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

In spite of modern technologies and safety concepts such as Hazard Analysis and Critical Control Point system (HACCP), the reported numbers of food-borne illnesses and intoxications are still on the increase. In addition, in recent years, the consumer demand towards high quality and safe foods is growing. These, in turn, have increased the need for using the protective cultures and associated antagonistic compounds (biopreservation) as additional factors to support good manufacturing practices, thereby reducing risks of growth and survival of pathogens and spoilage microorganisms. Lactic acid bacteria (LAB) have traditionally been used in food processing because of their ability to improve the organoleptic characteristics and healthiness of foodstuffs. Bacteriocins produced by LAB have received considerable attention in recent years because of their possible use as biopreservatives in food processing with resultant reduction in the use of chemical preservatives. Therefore, the main aim of the present study is evaluating the application of bacteriocin-producing LAB or their bacteriocins as biopreservatives.

Bacteriocins of Lactic Acid Bacteria is based on the 1990 Annual Meeting of the Institute of Food Technologists held in Dallas, Texas. It describes a number of well-characterized bacteriocins and, where possible, discusses practical applications for those that have been defined thus far from the lactic acid bacteria. The book begins with an introductory overview of naturally occurring antibacterial compounds. This is followed by discussions of methods of detecting bacteriocins and biochemical procedures for extraction and purification; genetics and cellular regulation of bacteriocins; bacteriocins based on the genera of lactic acid bacteria Lactococcus, Lactobacillus, Pediococcus, and Leuconostoc, and related bacteria such as Carnobacterium and Propionibacterium; and the regulatory and political aspects for commercial use of these substances. The final chapter sets out the prognosis for the future of this dynamic area. The information contained in this book should benefit those with interest in the potential for industrial use of bacteriocins as preservative ingredients. Anyone interested in lactic acid bacteria or the biosynthesis, regulation, and mechanisms of inhibition of these proteinaceous compounds will also appreciate the material presented. These include food scientists, microbiologists, food processors and product physiologists, food toxicologists, and food and personal product regulators.
