Essential Oils and Nanotechnology for Treatment of Microbial Diseases
by Mahendra Rai Susana Zacchino Marcos DeritaThere 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.
Essential Oils as Antimicrobial Agents in Food Preservation
by Jian JuPerishable 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.

Essential Oils: Applications and Trends in Food Science and Technology
by Mozaniel Santana de OliveiraOver the centuries humans have used essential oils in the most diverse applications, mainly medicinal, and as sources of bioactive molecules. They have been used in different industrial sectors, such as the pharmaceutical and chemical industries, cosmetics and more recently in the food industry. Due to new research in the field of food science and technology, new sources of bioactive compounds have been described, as they have been shown to be a viable alternative for applications in biofilms, nano emulsions, natural antioxidants, control of microorganisms such as fungi, bacteria and protozoa that can be pathological for human health. The use of essential oils in food science and technology is relatively new, with few articles and books in circulation covering new approaches. Essential Oils: Applications and Trends in Food Science and Technology provides relevant information on the applications of essential oils in this sector, bringing a reliable synopsis through literature reviews addressing mainly their use and perspectives and contributing in a systematic way to the dissemination of important knowledge on the use of essential oils in the area of food science and technology. This text presents new information on applications of essential oils in food science and covers Amazonian plants which are rich in essential oils plus new and developing sources of volatile and bioactive molecules. The use of essential oils in agriculture is covered in depth plus encapsulated and nano products used as food preservatives. As the first research work focusing exclusively on essential oils and their use in the food sector, this book can be used as a singular source for researchers seeking up-to-date coverage on this subject of emerging importance.
