Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2013-05-24 with total page 29 pages. Available in PDF, EPUB and Kindle. Book excerpt: High prevalence of multidrug-resistant microorganisms in the etiologic structure of different infectious processes significantly decreases the effectiveness of the treatment and enhances the probability of an unfavorable outcome from the infection. Combinations between antibiotics and other antimicrobial agents represent one of the most promising approaches for combating multidrug-resistant bacteria. A high therapeutic potential exists for combinations of antibiotics and natural antimicrobial substances with complex mechanisms of action and multiple healing properties, such as plant essential oils. The purpose of the present chapter is to review published studies on antibiotic-essential oil combinations and discuss the prospects for future studies. In general, many studies have shown the potential for essential oils to act synergistically with antibiotics in vitro. The main proposed mechanism of this beneficial effect is through inhibition of efflux pumps by some essential oils, which restores the activity of the antibiotic. Future efforts should be directed into further studies of antibiotic-essential oil combinations against multidrug-resistant bacteria, with an emphasis on understanding the mechanisms of the produced effect. Combinations of essential oils with different types of antimicrobial agents, such as bacteriophages, nanoparticles, and quorum-sensing inhibitors, require greater attention and are worthy of future investigations.

This book was released on 2017-10-03 with total page 682 pages. Available in PDF, EPUB and Kindle. Book excerpt: There has been emergence of multidrug resistance problem all over the world due to overuse or underuse of antibiotics. Most microbes including bacteria, fungi, protozoans and others have developed resistance to antibiotics, and therefore, this problem is now recognized to be of global concern. Ubiquitous occurrence of multidrug-resistant bacteria decreases effectiveness of current treatment, which results in thousands of deaths all over the world. Hence, investigations for new alternatives and novel strategies are urgently needed to address the problem of multidrug resistance. The antimicrobial potential of essential oils and metallic nanoparticles represent an effective solution for microbial resistance. Moreover, the use of essential oils in combination with metallic nanoparticles may exert synergistic antimicrobial effects and would be a novel approach. Essential oils (EOs) are volatile, natural, aromatic oily liquids that can be obtained from several parts of plants especially the aerial ones such as leaves and flowers. They are derived from complex metabolic pathways in order to protect plants from diverse pathogenic microorganisms. In fact, the bioactivity of EOs have been confirmed by several studies which have demonstrated their antibacterial, antiviral, anti-inflammatory, antifungal, antimutagenic, anticarcinogenic, and antioxidant properties. Nanotechnology is one of the most important and emerging technologies, which has brought about a technological revolution in the world. It has enormous applications in the field of medicine. Nanoparticles are very important tools in curing different diseases in general and microbial diseases in particular due to their significantly novel and improved chemical, physical and biological properties and high surface area-to-volume ratio. Among these, metal nanoparticles are known to play pivotal role in various biomedical applications. In this context, nanoparticles such as silver have shown their potential and could emerge as the new generation of antimicrobials. Silver nanoparticles have broad-spectrum biological activities and hence are used in many biomedical applications. The various biomedical applications of silver nanoparticles include treatment of wounds, burns, in water-disinfecting systems, in nanobased bone implantations, in dentistry for the development of dental materials and as antibacterial, antivirals, anti-protozoals, anti-arthropods and anticancerous agents. Apart from silver, noble metal nanoparticles like gold and platinum and other nanoparticles copper, oxides of different metals, etc. have been also the materials of choice for many scientists for their biological applications. The book will be of interest to chemists, microbiologists, biotechnologist, food technologists, nanotechnologists, pharmacologists, clinicians and those interested in nature cure. Students will find this book useful and reader friendly.

This book was released on 2017 with total page 226 pages. Available in PDF, EPUB and Kindle. Book excerpt: In developing countries including South Africa information is limited regarding the use of essential oils in treating antibiotic-resistant pathogenic bacteria. Currently, the battle between humans and the multitudes of infection and disease-causing pathogens continues. Emerging at the battlefield as some of the most significant challenges to human health is bacterial resistance to antibiotics and its rapid rise. This has become a major concern in global public health invigorating the need for new antimicrobial compounds. A rational approach to deal with antibiotic resistance problems requires detailed knowledge of the different biological and non-biological factors that affect the rate and extent of resistance development. Besides this approach, there are other approaches to resolving this challenge. For example, modulating the gut microbial community, either through feed additives (e.g. probiotics and prebiotics) or fecal transplantation could be a promising way to prevent certain diseases; non-antibiotic approaches include phage therapy, bacteriocins, and predatory bacteria which are effective against biofilms and can access recalcitrant infections. However, Allen and colleagues (2014) highlighted limitations of these antibiotic alternatives; these limitations include complex regulatory processes of the Food and Drug Administration (FDA) regarding feed additives, the high cost of vaccines as well as limited cross-protection of vaccines against some pathogens. The challenge with bacteriocins is possible sensitivity to proteolysis; phage therapy specificity begets technical limitation of administration against multiple subspecies while possible interactions of predatory with the host and their commensal microbiota are as yet unknown. Therefore, plants and their derivatives, such as essential oils, are currently blooming and represent a potential area for future investigations. This new generation of phytopharmaceuticals may shed light on the development of new pharmacological regimes in fighting antibiotic resistance. This study consolidates and describes the observed antagonistic outcome of essential oils against antibiotic-resistant S. aureus and B. cereus, and highlights the possibilities of essential oils as the potential antimicrobial agent. In the current study, the bacterial cell wall of antibiotic-resistant S. aureus and B. cereus was exposed as one of the targets for thyme essential oil. Thymus vulgaris essential oil showed high antimicrobial activity against the cell wall, cell membrane, and cytoplasm, and in some cases completely changed the morphology of the cells (antibiotic-resistant S. aureus and B. cereus). This indicates that the cell envelope became thinner than normal.

This book was released on 2013-05-24 with total page 51 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aromatic and medicinal plants, through their secondary metabolism, provide a complex mixture of volatile molecules known as essential oils. These volatile molecules exert antibacterial activity that has been used in folk medicine for centuries. During the last few decades, the emergence of antibacterial resistance has forced us to search for new and efficient antimicrobial agents. The significant number of studies on the use of essential oils and their components against multidrug-resistant bacteria, such as Acinetobacter baumannii, methicillin-resistant Staphylococcus aureus, Mycobacterium tuberculosis, and Pseudomonas aeruginosa show the exceptional potential of these natural products to curb the development of antibacterial resistance. Moreover, the use of essential oils and their components in combination with antibiotics may increase bacterial susceptibility, thus limiting resistance.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book excerpt: The use of natural antimicrobial compounds in food has gained much attention by the consumers and the food industry. This is primarily due to two major factors. First, the misuse and mishandling of antibiotics has resulted in the dramatic rise of a group of microorganisms including foodborne pathogens that are not only antibiotic resistant but also more tolerant to several food processing and preservation methods. In addition, increasing consumers,Äô awareness of the potential negative impact of synthetic preservatives on health versus the benefits of natural additives has generated interest among researchers in the development and use of natural products in foods. Essential oils are volatile, natural, complex compounds characterized by a strong odor and are formed by aromatic plants as secondary metabolites. The bioactivity properties of essential oils are generally determined by the major compounds present in them. They have been widely used for bactericidal, virucidal, fungicidal, antiparasitical, insecticidal, medicinal, and antioxidant applications. The biological activity of the oils can be compared with the activity of synthetically produced pharmacological preparations. Thus, essential oils are promising natural extracts that need further evaluation for possible application as supplement, preservatives, or antioxidants in food or pharmaceutical industries.
