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.

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.

Materials and equipment in food processing industries are colonized by surface-associated microbial communities called biofilms. In these biostructures microorganisms are embedded in a complex organic matrix composed essentially of polysaccharides, nucleic acids and proteins. This organic shield contributes to the mechanical biofilm cohesion and triggers tolerance to environmental stresses such as dehydratation or nutrient deprivation. Notably, cells within a biofilm are more tolerant to sanitation processes and the action of antimicrobial agents than their free living (or planktonic) counterparts. Such properties make conventional cleaning and disinfection protocols normally not effective in eradicating these biocontaminants. Biofilms are thus a continuous source of persistent microorganisms, including spoilage and pathogenic microorganisms, leading to repeated contamination of processed food with important economic and safety impact. Alternatively, in some particular settings, biofilm formation by resident or technological microorganisms can be desirable, due to possible enhancement of food fermentations or as a means of bioprotection against the settlement of pathogenic microorganisms. In the last decades substantial research efforts have been devoted to unravelling mechanisms of biofilm formation, deciphering biofilm architecture and understanding microbial interactions within those ecosystems. However, biofilms present a high level of complexity and many aspects remain yet to be fully understood. A lot of attention has been also paid to the development of novel strategies for preventing or controlling biofilm formation in industrial settings. Further research needs to be focused on the identification of new biocides effective against biofilm-associated microorganisms, the development of control strategies based on the inhibition of cell-to-cell communication, and the potential use of bacteriocins, bacteriocin-producing bacteria, phage, and natural antimicrobials as anti-biofilm agents, among others. This Research Topic aims to provide an avenue for dissemination of recent advances within the “biofilms” field, from novel knowledge on mechanisms of biofilm formation and biofilm architecture to novel strategies for biofilm control in food industrial settings.

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.

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.

Perishable products such as fruits and vegetables account for the largest proportion of food loss due to their short shelf life, especially in the absence of proper storage facilities, which requires sustainable, universal and convenient preservation technology. The existing methods to prolong the shelf life of food mainly include adding preservatives, irradiation, cold storage, heat treatment and controlled atmosphere storage. But with disadvantages in irradiation, cold storage, heat treatment and controlled atmosphere storage, chemical synthetic preservatives are still the main means to control food corruption. As the food industry responds to the increasing consumer demand for green, safe and sustainable products, it is reformulating new products to replace chemical synthetic food additives. Essential Oils as Antimicrobial Agents in Food Preservation provides a comprehensive introduction to the antimicrobial activity of plant essential oils and their application strategies in food preservation. It is aimed at food microbiology experts, food preservation experts, food safety experts, food technicians and students. Features: Summarizes the application strategy and safety of essential oil in the field of food preservation Describes the synergistic antibacterial effect of essential oil and antimicrobial agents Explains the action mechanism of essential oil as antimicrobial agent against foodborne fungi, foodborne bacteria, viruses and insects Analyzes the antimicrobial activity of essential oil in gas phase The book discusses how as a natural antimicrobial and antioxidant, essential oil has great potential to be used in the food industry to combat the growth of foodborne pathogens and spoilage microorganisms. But because the essential oil itself has obvious smell and is sensitive to light and heat, it cannot be directly added to the food matrix and thus the application strategies presented in this book explain how to alleviate those issues.
