Essential oils are also known as volatile oils, ethereal oils or aetherolea, or simply as the oil of the plant from which they were extracted. Essential oils are generally used in perfumes, cosmetics, soaps and other products, for flavoring food and drink, and for adding scents to incense and household cleaning products. Various essential oils have been used medicinally at different periods in history. Medical applications proposed by those who sell medicinal oils range from skin treatments to remedies for cancer, and often are based solely on historical accounts of use of essential oils for these purposes. Interest in essential oils has revived in recent decades with the popularity of aromatherapy, a branch of alternative medicine that claims that essential oils and other aromatic compounds have curative effects. Oils are volatilized or diluted in carrier oil and used in massage, diffused in the air by a nebulizer, heated over a candle flame, or burned as incense. This book describes about the physicochemical properties, chemical composition, distillation, yield, quality of essential oils, process of extraction of essential oils, manufacture of essential oils, products derived from essential oils and so on. The book in your hands contains formulae, processes, and test parameters of different types of essential oils derived from different natural sources. This is very helpful book for new entrepreneurs, professionals, institutions and for those who are already engaged in this field.

Egyptian hieroglyphs, Chinese scrolls, and Ayurvedic literature record physicians administering aromatic oils to their patients. Today society looks to science to document health choices and the oils do not disappoint. The growing body of evidence of their efficacy for more than just scenting a room underscores the need for production standards, quality control parameters for raw materials and finished products, and well-defined Good Manufacturing Practices. Edited by two renowned experts, the Handbook of Essential Oils covers all aspects of essential oils from chemistry, pharmacology, and biological activity, to production and trade, to uses and regulation. Bringing together significant research and market profiles, this comprehensive handbook provides a much-needed compilation of information related to the development, use, and marketing of essential oils, including their chemistry and biochemistry. A select group of authoritative experts explores the historical, biological, regulatory, and microbial aspects. This reference also covers sources, production, analysis, storage, and transport of oils as well as aromatherapy, pharmacology, toxicology, and metabolism. It includes discussions of biological activity testing, results of antimicrobial and antioxidant tests, and penetration-enhancing activities useful in drug delivery. New information on essential oils may lead to an increased understanding of their multidimensional uses and better, more ecologically friendly production methods. Reflecting the immense developments in scientific knowledge available on essential oils, this book brings multidisciplinary coverage of essential oils into one all-inclusive resource.

Although many foods are appealing, and even perceived as natural, in spite of containing synthetic additives, consumer increasingly prefer food products which are fully natural. This has driven an increase in the use of, and interest in, food additives derived from biological sources. Of particular interest are natural food flavors and colors, which have started to play a major role in food processing. This volume presents practical information on over 80 natural extracts that can be used as food flavors and colors, drawing on the author's 50 years of food chemistry and technology expertise in both research and industry. The book is divided into three parts: Part I deals with manufacture, quality, analysis, and regulatory aspects. Part II describes the various sources of natural flavors and colorants that are currently available, alphabetized for convenient reference. Part III covers future directions that can be pursued by research workers and manufacturers. Food scientists, researchers and product development professionals alike will find Natural Food Flavors and Colorants an invaluable resource for understanding and using these commercially important natural food ingredients.

Crazing Technology for Polyester Fibers reviews PET fibers crazing in surface-active liquids and the use of the crazing mechanism for fiber modification by functional additives.

With two highly regarded and very experienced authors bringing together the latest information on polyester crazing technology, this book is essential reading for scientific researchers, engineers, and R&D professionals working on the development of fibers for improving the properties of textiles. - Explains fiber crazing mechanisms and processes with a view to their use in developing polyester-based high-performance textiles - Focuses on how this mechanism can be used to confer important characteristics, such as antimicrobial properties, reduced flammability, and repellency, making this essential reading for textile scientists and technicians - Explores novel techniques and methods for readers who require cutting-edge knowledge of developments in fiber crazing

Food Processing Technology: Principles and Practice, Fifth Edition includes emerging trends and developments in food processing. The book has been fully updated to provide comprehensive, up-to-date technical information. For each food processing unit operation, theory and principles are first described, followed by equipment used commercially and its operating conditions, the effects of the operation on micro-organisms, and the nutritional and sensory qualities of the foods concerned. Part I describes basic concepts; Part II describes operations that take place at ambient temperature; Part III describes processing using heat; Part IV describes processing by removing heat; and Part V describes post-processing operations. This book continues to be the most comprehensive reference in the field, covering all processing unit operations in a single volume. The title brings key terms and definitions, sample problems, recommended further readings and illustrated processes. - Presents current trends on food sustainability, environmental considerations, changing consumer choices, reduced packaging and energy use, and functional and healthy/plant-based foods - Includes highly illustrated line drawings and/or photographs to show the principles of equipment operation and/or examples of equipment that is used commercially - Contains worked examples of common calculations

Modern flavours and fragrances are complex formulated products,containing blends of aroma compounds with auxiliary materials,enabling desirable flavours or fragrances to be added to a hugerange of products. From the identification and synthesis ofmaterials such as cinnamaldehyde and vanillin in the 19th Centuryto the current application of advanced analytical techniques foridentification of trace aroma compounds present in naturalmaterials, the flavour and fragrance industry has developed as akey part of the worldwide specialty chemicals industry. With contributions mainly coming from industry based experts,Chemistry & Technology of Flavours and Fragrancesprovides a detailed overview of the synthesis, chemistry andapplication technology of the major classes aroma compounds. Withseparate chapters covering important technical aspects such as thestability of aroma compounds, structure – odour relationshipsand identification of aroma compounds, this book will be essentialreading for both experienced and graduate level entrants to theflavour & fragrance industry. It will also serve as animportant introduction to the subject for chemists andtechnologists in those industries that use flavours and fragrances,eg food, cosmetics & toiletries, and household products.
