The purpose of this Brief is to provide a global view of the concept of biopreservation and its potential and existing applications in the different food sectors. Biopreservation, an approach already experimented with by our ancestors, has been used empirically for centuries and now the rationale behind it is becoming increasingly popular, applied singly or in combination with novel and classical food processing technologies. The growing world population, together with the globalization of the food market and consumer demand for foods that are ready to eat, lightly preserved, fresh-tasting, and rich in flavor, nutrients, and bioactive compounds, is forcing the food industry to develop less aggressive food preservation methods.
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.
Food Biopreservatives of Microbial Origin provides basic and applied information regarding how antimicrobial metabolites of safe, food-grade bacteria (used in food fermentation) can be utilized as food preservatives. The authors discuss why biopreservation of food is important, identify the foods and microoganisms for which biopreservation is suitable, and explore the potential of bacteriocins of food-grade starter culture bacteria and the antimicrobial proteins of yeasts as possible food biopreservatives. The book is a valuable reference resource that will benefit students of food science and researchers in food industries, regulatory agencies, and advisory groups.

The aim of "Novel Approaches in Biopreservation for Food and Clinical Purposes" is to provide cutting-edge information on biopreservation methods for both food and medical applications. The book has one chapter dedicated to each major food category (milk and dairy, vegetables, meat, fish, bread, flours and beverages) and brief chapters covering preservation approaches for pharmaceuticals, embryos, gametes, cells and tissues. This book assumes a basic understanding of microbiology and food science, aiming to offer an overview of the most commonly and updated techniques currently used, including protective cultures and fermentation starters, bacterial metabolites, essential oils, bacteriophages or endolysins. By presenting this comprehensive overview, the book aims to advance knowledge in the field of biopreservation and foster its implementation in both food and clinical contexts.
Safety, quality, and prolonged shelf life of food products are the three most important aspects of the food industry. To ensure a satisfactory scale, both traditional and modern preservatives are widely used. However, as eating habits have upgraded with a focus on what is popularly termed "a healthy diet," there has been a growing demand for food with natural additives over synthetic ingredients. As a result, there have been major developments in the field of food preservation, which are presented in this book. The book provides detailed information on the range of natural food preservatives with their applications in different product sectors. It delves into microbiological food spoilage and discusses natural food preservatives as well as natural antioxidants and antimicrobials as food ingredients. It reviews prevalent preservation technologies, the chemistry behind them, and new nonconventional preservatives. It focuses on innovative technologies, including biological antimicrobial systems such as LABs or their metabolites, bacteriophages, and bacteriophage-encoded enzymes. It provides knowledge about preservatives, such as bacteriocins and ε-polylysine, as well as their usage in achieving the right balance of safety, quality, and shelf-life for specific products. The book is a collection of the research and experiences of an international team of experts and is a valuable tool for all those who are related to the advancements and production of safe and healthy foods. It is a significant reference book for professionals who teach food microbiology courses, conduct research and epidemiologic investigations, analyze food samples, and craft food safety policies.
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
