Essential Oils as antimicrobials in food systems a review
Food Control, 2015Co-Authors: Juliany Rivera Calo, Philip G Crandall, Corliss A Obryan, Steven C RickeAbstract:Many consumers are demanding foods without what they perceive as artificial and harmful chemicals, including many used as antimicrobials and preservatives in food. Consequently, interest in more natural, non-synthesized, antimicrobials as potential alternatives to conventional antimicrobials to extend shelf life and combat foodborne pathogens has heightened. Aromatic plants and their components have been examined as potential inhibitors of bacterial growth and most of their properties have been linked to Essential Oils and other secondary plant metabolites. Historically, Essential Oils from different sources have been widely promoted for their potential antimicrobial capabilities. In this review, mechanisms of antimicrobial action, and the antimicrobial properties of plant Essential Oils are discussed, including their mode of action, effectiveness, synergistic effects, major components and use in foods.

Essential Oils: Sources of Antimicrobials and Food Preservatives
Frontiers in Microbiology, 2017Co-Authors: Abhay K. Pandey, Pradeep Kumar, Pooja Singh, N. N. Tripathi, Vivek K. BajpaiAbstract:Aromatic and medicinal plants produce Essential Oils in the form of secondary metabolites. These Essential Oils are having a diverse way of application in the food system, perfumery, and cosmetics. The use of Essential oil as antimicrobial and food preservative agents is of great concern because of several side effects of synthetics. These Oils have a potential to be used as food preservative including cereals, grains, pulses fruits, and vegetables. In the current review, we have briefly reviewed the literature and summarizing the uses of Essential Oils with special emphases on the antibacterial, bactericidal, antifungal, fungicidal and food preservative properties. These Essential Oils have pronounced antimicrobial and food preservative properties because Essential Oils consist of various active constituents (terpenes, terpenoids, carotenoids, coumerines, curcumines) with great significance for food industries. Thus, these properties of Essentials Oils offer a possibility to substitutive natural, safe, eco-friendly, cost-effective, renewable and easily biodegradable antimicrobials for food commodities preservation in near future.

Essential Oils and antifungal activity
Pharmaceuticals, 2017Co-Authors: Filomena Nazzaro, Florinda Fratianni, Raffaele Coppola, Vincenzo De FeoAbstract:Since ancient times, folk medicine and agro-food science have benefitted from the use of plant derivatives, such as Essential Oils, to combat different diseases, as well as to preserve food. In Nature, Essential Oils play a fundamental role in protecting the plant from biotic and abiotic attacks to which it may be subjected. Many researchers have analyzed in detail the modes of action of Essential Oils and most of their components. The purpose of this brief review is to describe the properties of Essential Oils, principally as antifungal agents, and their role in blocking cell communication mechanisms, fungal biofilm formation, and mycotoxin production.

effect of Essential Oils on pathogenic bacteria
Pharmaceuticals, 2013Co-Authors: Filomena Nazzaro, Florinda Fratianni, Raffaele Coppola, Laura De Martino, Vincenzo De FeoAbstract:The increasing resistance of microorganisms to conventional chemicals and drugs is a serious and evident worldwide problem that has prompted research into the identification of new biocides with broad activity. Plants and their derivatives, such as Essential Oils, are often used in folk medicine. In nature, Essential Oils play an important role in the protection of plants. Essential Oils contain a wide variety of secondary metabolites that are capable of inhibiting or slowing the growth of bacteria, yeasts and moulds. Essential Oils and their components have activity against a variety of targets, particularly the membrane and cytoplasm, and in some cases, they completely change the morphology of the cells. This brief review describes the activity of Essential Oils against pathogenic bacteria.

preservation of chicken breast meat treated with thyme and balm Essential Oils
Journal of Food Science, 2010Co-Authors: Florinda Fratianni, Raffaele Coppola, Vincenzo De Feo, Laura De Martino, Antonio Melone, Filomena NazzaroAbstract:Abstract: The present study evaluated the effects of thyme and balm Essential Oils on the 3-wk storage of fresh chicken breast meat at 4 °C. Thyme and, to a lesser extent, balm Essential Oils reduced DPPH (2,2-diphenyl-1-picrylhydrazyl) radical formation in the meat (25% to 30% and 20%, respectively). Treatment with the 2 Essential Oils also limited lipid peroxidation and the deterioration of sarcoplasmic proteins, helping to preserve the meat even after 2 wk of storage. Thyme and balm Essential Oils decreased the natural microflora present in the meat; total microbial content decreased down to 50% in comparison to the control samples. In addition, a clear effect on lactic acid bacterial growth was recorded. Balm Essential oil significantly limited the growth of Salmonella sp., whereas thyme Essential oil effectively inhibited the growth of Escherichia coli. Our data demonstrate that these 2 Essential Oils effectively reduced deteriorative processes in chicken meat and extended the shelf life of this fresh product. Practical Application: The Essential Oils of thyme and balm can protect the chicken meat from decomposition during the storage time.

Phytotoxic Activities of Mediterranean Essential Oils
MDPI AG, 2010Co-Authors: Luiz Fernando Rolim De Almeida, Laura De Martino, Fernando Frei, Emilia Mancini, Vincenzo De FeoAbstract:Twelve Essential Oils from Mediterranean aromatic plants were tested for their phytotoxic activity, at different doses, against the germination and the initial radicle growth of seeds of Raphanus sativus, Lactuca sativa and Lepidium sativum. The Essential Oils were obtained from Hyssopus officinalis, Lavandula angustifolia, Majorana hortensis, Melissa officinalis, Ocimum basilicum, Origanum vulgare, Salvia officinalis and Thymus vulgaris (Lamiaceae), Verbena officinalis (Verbenaceae), Pimpinella anisum, Foeniculum vulgare and Carum carvi (Apiaceae). The germination and radicle growth of tested seeds were affected in different ways by the Oils. Thyme, balm, vervain and caraway Essential Oils were more active against both germination and radicle elongation

supercritical fluid extraction and fractionation of Essential Oils and related products
Journal of Supercritical Fluids, 1997Co-Authors: Ernesto ReverchonAbstract:Supercritical CO2 extraction of Essential Oils is one of the most widely discussed applications in the supercritical fluid literature. Nevertheless, a comprehensive overview of the analytical, processing and modeling aspects has never been attempted. This is partly due to the difficulties involved in isolating Essential Oils from the other products which supercritical CO2 can dissolve. Moreover, only a limited number of studies provide quantitative data on the parameters governing this process. In this review, solubility data on pure compounds belonging to Essential Oils are analyzed. Processes proposed to isolate and fractionate Essential Oils by supercritical CO2 and the corresponding modelling aspects are discussed critically.

Essential Oils: Extraction Techniques, Pharmaceutical And Therapeutic Potential - A Review
Current Drug Metabolism, 2018Co-Authors: Zarith Asyikin Abdul Aziz, Akil Ahmad, Alptug Karakucuk, Muhammad Mohsin Azim, David Lokhat, Magdah Ganash, Siti Hamidah Mohd Setapar, Mohammad A Kamal, Mohd Rafatullah, Ghulam Md AshrafAbstract:Essential Oils are liquid extracts from aromatic plants, which have numerous applications in multiple industries. There are a variety of methods used for the extraction of Essential Oils, with each method exhibiting certain advantages and determining the biological and physicochemical properties of the extracted Oils. Essential Oils from different plant species contain more than 200 constituents which are comprised of volatile and non-volatile components. The application of Essential Oils as antimicrobial, anticancer, anti-inflammatory and anti-viral agents is due to their effective and efficient properties, inter alia. Several advanced (supercritical fluid extraction, subcritical extraction liquid, solvent-free microwave extraction) and conventional (hydrodistillation, steam distillation, hydrodiffusion, solvent extraction) methods have been discussed for the extraction of Essential Oils. Advanced methods are considered as the most promising extraction techniques due to less extraction time, low energy consumption, low solvent used and less carbon dioxide emission. This manuscript reviewed the major research studies in the field and discussed several research findings on the chemical composition of Essential Oils, methods of oil extraction, and application of these Oils in pharmaceutical and therapeutic fields. These Essential Oils can be used as anticancer, antimicrobial, antiviral, and as skin permeation enhancer agents.
