Book excerpt: Essential oils This exciting new volume, written and edited by some of the world’s foremost experts in the field, provides up-to-date information about the chemical structure of essential oils, as well as their therapeutic and biological actions. It defines their functional uses while evaluating the advantages and disadvantages of their application in various sectors. Essential oils have been used by global communities for centuries, for different purposes such as medicinal, flavoring, preservatives, perfumery, aromatherapy, dentistry, cosmetics, insecticide, fungicide, and bactericide, among others. Essential oils are natural and biodegradable substances, usually non-toxic or with low toxicity to humans. Essential oils are botanical products that have volatile nature, known for their special odor, and found to be effective in the treatment of oxidative stress, cancer, epilepsy, skin allergies, indigestion, headache, insomnia, muscular pain, respiratory problems, etc. Essential oils principally enhance resistance to abiotic stress and protection against aquatic herbivores. They possess antimicrobial, antifungal, antitumor, and antioxidant properties. Essential oils are known to be volatile and susceptible to degradation from various ambient conditions, including temperature, air, light, and humidity, which limits their applications. Encapsulation is a proven technique that can protect essential oils and enable their use in various applications. This book aims to provide current knowledge on the chemical structure, therapeutic, and biological activities of essential oils, as well as to describe their functional uses and assess the benefits and drawbacks of their usage in various fields. By exploring the latest research on essential oils and their encapsulation, this book offers valuable insights and practical guidance for anyone interested in the science and application of these fascinating compounds.

Download or read book Quality Handling and Evaluation written by Ramdane Dris and published by Springer Science & Business Media. This book was released on 2007-05-08 with total page 525 pages. Available in PDF, EPUB and Kindle. Book excerpt: Food quality is becoming an ever-increasing important feature for consumers and it is well known that some food crops are perishable and have a very short shelf and storage life. An effective quality assurance system throughout the handling steps between harvest and retail display is essential to provide a consistently good quality supply of fresh food crops to the consumers and to protect the reputation of a given marketing label. Food manufacturing companies all over the world are incre- ingly focussing on quality aspect of food including minimally processed food to meet consumer demands for fresh-like and healthy food products. To investigate and control quality, one must be able to measure quality-related attributes. Quality of produce encompasses sensory attributes, nutritive values, chemical constituents, mechanical properties, functional properties and defects. Successful postharvest handling of crops requires careful coordination and integration of the various steps from harvest operations to consumer level in order to maintain the initial product quality. Maturity at harvest is one feature of quality of perishable products, it has great influence on their postharvest behavior during marketing. Safety assurance can be part of quality assurance and its focus on minimizing chemical and microbial contamination during production, harvesting, and postharvest handling of intact and fresh-cut of commodities. Essentially, electromagnetic (often optical) prop- ties relate to appearance, mechanical properties to texture, and chemical properties to flavor (taste and aroma).
Download or read book Selected Topics in the Chemistry of Natural Products written by Raphael Ikan and published by World Scientific. This book was released on 2008 with total page 625 pages. Available in PDF, EPUB and Kindle. Book excerpt: Labor is the most important of the three traditional factors of production (land, labor and capital), accounting for some 75 per cent of the GDP. It is therefore important to focus on issues of labor economics. In this book the approach taken will be that of the free market philosophy of libertarianism, the perspective that allows the maximum of freedom, consistent with the responsibility of all to respect the equal rights of all others. The position of this book on unions is unique outside of the libertarian movement, and this is indicative of its analysis of several other issues, such as minimum wages. For scholars on the left, it is almost true that unions can do no wrong (for Marxists, they do not do enough, but that is another story). Their role is to raise wages for the workingman, and this task is almost unstintingly applauded. Conservatives, on the other hand, oppose unions root and branch (except for their support of foreign wars, which is also another story). To this end they support a welter of regulations, designed to reduce their power: limitations of check offs, forced secret ballots, etc. For libertarians, the analysis depends, intimately, on whether or not these are voluntary organizations. If they are, there is no more justification for imposing secret ballots on them than to do so for the chess or garden club. If they are not, they should not be weakened by restrictions, but, rather, banned, and their leaders imprisoned.

Download or read book Essential Oils written by AntonC. deGroot and published by Routledge. This book was released on 2021-04-12 with total page 1278 pages. Available in PDF, EPUB and Kindle. Book excerpt: Essential Oils: Contact Allergy and Chemical Composition provides a full review of contact allergy to essential oils along with detailed analyses of the chemical composition of essential oils known to cause contact allergy. In addition to literature data, this book presents the results of nearly 6,400 previously unpublished sample analyses, by far the largest set of essential oils analyses ever reported in a single source of scientific literature. Covering 91 essential oils and two absolutes, the book presents an alphabetical list of all 4,350 ingredients that have been identified in them, a list of chemicals known to cause contact allergy and allergic contact dermatitis, and tabular indications of the ingredients that can be found in each essential oil. The book discusses contact allergy and allergic contact dermatitis for each of the oils and absolutes, sometimes able to provide only one or two reports but drawing upon considerable amounts of literature in other cases, such as with tea tree oil, ylang-ylang oil, lavender oil, rose oil, turpentine oil, jasmine absolute, and sandalwood oil. While limited information on the main components and their concentrations would be enough for most dermatologists, this book gives extensive coverage not only to improve levels of medical knowledge and quality of patient care, but also for the benefit of professionals beyond clinical study and practice, such as chemists in the perfume and cosmetics industries, perfumers, academic scientists working with essential oils and fragrances, aromatherapists, legislators, and those involved in the production, sale, and acquisition of essential oils.
Download or read book Massage and Aromatherapy written by Andrew Vickers and published by Springer. This book was released on 2013-11-11 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book aims to give health professionals a balanced and indepen dent overview of massage and aromatherapy. I have written it because, despite growing interest, there is a dearth of professional literature on this subject. This book aims to cover a number of topics which are under-represented in existing publications. These include: • scientific research in massage and aromatherapy; • the use of the therapies in medical settings; • the knowledge base of massage and aromatherapy; • professional and managerial issues; • safety. Understanding of these subjects is essential for any reasoned evalu ation of massage and aromatherapy. Yet this book is probably the first to provide information suitable for this task. At the current time of writing, almost all books on massage and aroma therapy have been written with the lay public in mind. The texts recommended to students and practitioners by the foremost schools and institutions are exactly the same as those available in health food shops as general introductions for prospective patients. Not surprisingly, such books generally fail to include in-depth discussions of professional issues.
