Natural Antimicrobials In Food Safety And Quality

The demands of producing high quality, safe (pathogen-free) food rely increasingly on natural sources of antimicrobials to inhibit food spoilage organisms and foodborne 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.

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

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

Consumers demand food products with fewer synthetic additives but with increased safety, quality and shelf-life. These demands have led to renewed interest in the use of natural antimicrobials to preserve foods. However, despite the wide range of potential antimicrobials, relatively few are suitable for use in practice in particular food products. Edited by a leading expert in the field, and with a distinguished international team of contributors, Natural antimicrobials for the minimal processing of foods discusses their practical application in food preservation, often in conjunction with other preservation techniques. After an introductory chapter, the book first discusses the use of bacteriocins such as nisin in preserving animal and other food products, often in conjunction with other preservation techniques such as high hydrostatic pressure and pulsed electric fields. Subsequent chapters discuss the current and future uses of natamycin, organic acids, antimicrobials from animals and chitosan as preservatives. Three chapters are devoted to antimicrobials from plants and their use in a wide range of applications, including the preservation of fresh and minimally-processed fruits and vegetables. A final group of chapters discuss the use of natural antimicrobials in edible coatings, applications of natural antifungal agents, the combination of natural antimicrobials with irradiation, and the regulatory context. With its practical emphasis and authoritative coverage, Natural antimicrobials for the minimal processing of foods is a standard work for the food industry in developing new preservation systems that extend the shelf-life of foods without compromising safety or sensory quality. Discusses the practical application of antimicrobials in food preservation, often in conjunction with other preservation techniques Discusses the uses of natamycin, organic acids, antimicrobials from animals and chitosan as preservatives A standard work for the food industry in developing new preservation systems that extend the shelf-life of foods without compromising safety or sensory quality

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.

This edited volume provides up-to-date information on recent advancements in efforts to enhance microbiological safety and quality in the field of food preservation.
