Natural additives are increasingly favoured over synthetic ones as methods of ensuring food safety and long shelf-life. The antimicrobial properties of both plant-based antimicrobials such as essential oils and proteins such as bacteriocins are used in, for example, edible preservative films, in food packaging and in combination with synthetic preservatives for maximum efficacy. New developments in delivery technology such as nanoencapsulation also increase the potential of natural antimicrobials for widespread use in industry. Part one introduces the different types of natural antimicrobials for food applications. Part two covers methods of application, and part three looks at determining the effectiveness of natural antimicrobials in food. Part four focuses on enhancing quality and safety, and includes chapters on specific food products. Reviews different types of antimicrobials used in food safety and quality Covers how antimicrobials are created to be used in different foods Examines how the antimicrobials are used in foods to enhance the safety and quality
With consumer awareness about food safety and quality, there is a high demand for the preservative (synthetic)-free foods and use of natural products as preservatives. Natural antimicrobials from different sources are used to preserve food from spoilage and pathogenic microorganisms. Plants (herbs and spices, fruits and vegetables, seeds and leaves) are the main source of antimicrobials and contain many essential oils that have preservation effect against different microorganisms. Mainly, herb and spices contain many essential oils and the examples include rosemary, sage, basil, oregano, thyme, cardamom, and clove. These essential oils are very effective against many pathogenic and spoilage microorganisms like Salmonella, Escherichia coli, Listeria monocytogenes, Campylobacter spp., and Staphylococcus aureus and help to increase their quality and shelf stability. These antimicrobial compounds are also used in combination with edible food coatings and inhibit the ability of microorganisms to grow on the surface of food and food products.
The demands of producing high quality, safe (pathogen-free) food rely increasingly on natural sources of antimicrobials to inhibit food spoilage organisms and food-borne pathogens and toxins. Discovery and development of new antimicrobials from natural sources for a wide range of application requires that knowledge of traditional sources for food antimicrobials is combined with the latest technologies in identification, characterization and application. This book explores some novel, natural sources of antimicrobials as well as the latest developments in using well-known antimicrobials in food. Covering antimicrobials derived from microbial sources (bacteriophages, bacteria, algae, fungi), animal-derived products (milk proteins, chitosan, reduction of biogenic amines), plants and plant-products (essential oils, phytochemicals, bioactive compounds), this book covers the development and use of natural antimicrobials for processed and fresh food products. New and emerging technologies concerning antimicrobials are also discussed.
Twelve years have passed since its last edition - making Antimicrobials in Foods, Third Edition the must-have resource for those interested in the latest information on food antimicrobials. During that time, complex issues regarding food preservation and safety have emerged. A dozen years ago, major outbreaks of Escherichia coli O157:H7 and Listeri
The world is full of plants and animals that have their own defenses, producing various substances in their daily fight against bacteria, fungi, or other agents. These products are alternatives to conventional antimicrobials that have a poor reputation with consumers. Many of these compounds are well known; however, the multiple types of structures together with the variable responses depending of the type of biocontrol needed in a wide range of applications, such as clinical, agricultural, general hygiene, and food, necessitates the continuous search for specific applications and the continuous study of how to use these substances. The present book provides a summary of reviews and original research works that explore the multiple alternatives for the use of these compounds.
Documenting the latest research in the field of different pathogenic organisms, this book presents the current scenario about promising antimicrobials in the following areas: Part I. Plants as source of antibacterials, Part II. Naturally occurring antifungal natural products, Part III. Antiparasitic natural products, Part IV. Antiviral natural products. Renowned scientists from the globe have been selected as authors to contribute chapters. Use of plants for various ailments is as old as human civilization and continuous efforts are being made to improve medicinal plants or to product their bioactive secondary metabolites in high amounts through various technologies. About 200,000 natural products of plant origin are known and many more are being identified from higher plants and micro-organisms. Some plants based drugs are used since centuries and there is no alternative medicine for many such drugs as cardiac glycosides. Drug discovery from medicinal plants or marine micro-organisms continues to provide an important source of new drug leads. Research on new antibacterials represents a real and timely challenge of this century, particularly for the treatment of infections caused by clinical isolates that show multidrug resistance. The main microorganisms involved in the resistance process have been identified and given the acronym ESKAPE for Enterococcus faecium, Staphylococcus aureus, Klebsiella pneumoniae, Acinetobacter baumanii, Pseudomonas aeruginosa and Enterobacteriaceae. Multidrug resistant Mycobacterium tuberculosis including highly drug-resistant strains (XDR-TB) has also emerged as one of the most important clinical challenges of this century. Plants of diverse taxa and marine micro-organisms are rich source of these antimicrobials. An attempt has been made to compile the recent information about natural sources of antibacterials and their sustainable utilization. Increased panic of these pathogens warrants a growing demand for research to undertake the threat of multidrug resistance. The search for new antifungal, antiparasitic and antiviral natural products is far from devoid of interest. According to the WHO report in 2013, malaria still represents some 207 million cases worldwide and more than 3 billion of people are still exposed to this risk. Similarly, about 350 million people are considered at risk of contracting leishmaniasis. The fight against some viruses also requires that the research on natural products continue. For example, even if an antiretroviral with direct action was recently approved in Europe in 2013, its high cost does not allow to offer it to an exposed population in countries where the cost of drugs remains a problem for a large part of the population. These books are useful to researchers and students in microbiology, biotechnology, pharmacology, chemistry and biology as well as medical professionals.

It is estimated that foodborne microorganisms in the United States cause 48 million sicknesses, 128,000 hospitalizations and 3,000 deaths each year. Food spoilage due to decay-causing microorganisms is also an issue in both developing and developed countries with 30-40% annual loss of fruits and vegetables. Synthesized antimicrobials (preservatives) are commonly used by the food industry to enhance microbial safety and increase shelf-life. However, food and agricultural industries are experiencing a lack of potent antimicrobial agents to secure the safety and maintain the quality of food products. Some synthetic preservatives may produce harmful by-products and damage the environment. There is also increasing incidence of antibiotics-resistant pathogens which has drawn great concern from the scientific communities and public health professionals. Therefore, there is increasing interest in the use of natural antimicrobials to enhance microbial safety, reduce spoilage and extend the shelf life of food. Natural antimicrobials are from plants, microorganisms and animals. They cover a wide variety of compounds including phenolics, terpenes, bacteriocins, peptides, proteins, natural polymers, fatty acids (lipids), and organic acids. Overall reviews of well-known natural or bio-based antimicrobials are first presented. The book then discusses antimicrobials of plant sources and their applications in foods and animal health. A number of chapters address the combinations of natural antimicrobials with non-thermal processing technologies to achieve additive and synergistic effects. The use of natural antimicrobials in packaging and coating, as well as both well-studied and novel biobased antimicrobials are discussed. Furthermore, the needs for toxicological evaluations of natural and bio-based antimicrobials are presented and protocols are recommended. Moreover, there is discussion in many of the chapters on the modes of action, mechanisms, and industrial aspects of applying natural or bio-based antimicrobials.
Consumer concerns play a critical role in dictating the direction of research and development in food protection. The rising demand for minimally processed foods, growing concerns about the use of synthetic preservatives, and suspected links between the overuse of antibiotics and multi-drug resistance in microbes has made food safety a global priority. Natural Food Antimicrobial Systems focuses on advances in the technology of food safety. Numerous antimicrobial agents exist in animals and plants where they evolved as defense mechanisms. For example, the antimicrobial components of milk have been unraveled in recent years. The book covers how these components - such as lactoferrin - can be used as multifunctional food additives such as antioxidants and immuno-modulating agents. The six sections cover lacto-antimicrobials, ovo-antimicrobials, phyto-antimicrobials, bacto-antimicrobials, acid-antimicrobials, and milieu-antimicrobials. Each chapter provides background and historical information, molecular properties, antimicrobial activity, biological advantage, applications, safety, tolerance, and efficacy, and biotechnology. To satisfy the rapidly changing consumption patterns of the global market, the food processing industry continuously searches for new technologies in food science. Designed as a reference for academia and corporate R & D, Natural Food Antimicrobial Systems fills this need, offering in-depth information on emerging biotechnology, efficacy, and applications of natural food antimicrobial systems.
Fifteen years have passed since the 3rd edition of Antimicrobials in Food was published. It was arguably considered the "must-have" reference for those needing information on chemical antimicrobials used in foods. In the years since the last edition, the food industry has undergone radical transformations because of changes on several fronts. Reported consumer demands for the use of "natural" and "clean-label" antimicrobials have increased significantly. The discovery of new foodborne pathogen niches and potentially hazardous foods, along with a critical need to reduce food spoilage waste, has increased the need for suitable antimicrobial compounds or systems. Novel natural antimicrobials continue to be discovered, and new research has been carried out on traditional compounds. These and other related issues led the editors to develop the 4th edition of Antimicrobials in Food. In the 4th edition, the editors have compiled contemporary topics with information synthesized from internationally recognized authorities in their fields. In addition to updated information, new chapters have been added in this latest release with content on the use of bacteriophages, lauric arginate ester, and various systems for antimicrobial encapsulation and delivery. Comprehensive revisions of landmark chapters in previous editions including naturally occurring antimicrobials from both animal and plant sources, methods for determining antimicrobial activity, new approaches to multifactorial food preservation or "hurdle technology," and mechanisms of action, resistance, and stress adaptation are included. Complementing these topics is new information on quantifying the capability of "clean" antimicrobials for food preservation when compared to traditional food preservatives and industry considerations when antimicrobials are evaluated for use in food manufacture. Features Covers all food antimicrobials, natural and synthetic, with the latest research on each type Contains 5,000+ references on every conceivable food antimicrobial Guides in the selection of appropriate additives for specific food products Includes innovations in antimicrobial delivery technologies and the use of multifactorial food preservation with antimicrobials
