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 huge range of products. The flavour and fragrance industry is a key part of the worldwide specialty chemicals industry, yet most technical recruits have minimal exposure to flavours and fragrances before recruitment. The analytical chemistry of flavour and fragrance materials presents specific challenges to the analytical chemist, as most of the chemicals involved are highly volatile, present in very small amounts and in complex mixtures. Analytical Methods for Flavor and Fragrance Materials covers the most important methods in the analysis of flavour and fragrance materials, including traditional and newly emerging methodologies. It discusses the capabilities of the various analytical methods for flavour and fragrance analysis and guides the newcomer to the most appropriate techniques for specific analytical problems.

It happened in Manchester, May 12-14, 2004. - For the fifth time since the early 1990's the Royal Society of Chemistry and the Society of the Chemical Industry jointly held their 'flavours & fragrances' conference, this time in the Manchester Conference Centre of the UMIST Manchester. The meeting saw over one hundred participants from one dozen countries, and was the largest of the series so far. In two and a half days divided into five sessions, twenty-five speakers from academia and industry alike presented their recent research results related to this exciting field, including Natural Products, Foods and Flavors, Perfumery and Olfaction, and last but not least Fragrance Chemistry. Research is more than ever central to the F&F industry with its constant demand for innovation and its frequently changing trends. Especially, in the classic and well-explored domains of musks and amber odorants fascinating new discoveries were made only very recently, which proves the endless possibilities in the search for new aroma chemicals. This was also reflected in the logo of the conference, which featured Ambrocenide? as a new powerful ambery odorant that emerged from classical cedrene chemistry - and it is as well reflected in four of the sixteen conference papers that are collected in this special issue of Chemistry & Biodiversity. With its focus on biorelevant chemicals, Chemistry & Biodiversity was predestined to publish the diverse highlight papers of the 'flavours & fragrances' conference. Fragrance and fragrance materials by definition elicit a biological response, serve as versatile signals, trigger the sense of smell and taste in various ways - and every odorant design is nothing more than 'chemistry probing nature'. But Fragrance Chemistry can also document and even preserve the biodiversity of scents, as was the topic of the lecture of Roman Kaiser, which had been published in advance as the first full paper of Chemistry & Biodiversity.

The volume deals with several aspects of the chemistry of both synthetic and natural organic compounds related to flavours and fragrances. It presents very recent results, some of them previously unpublished, and findings related to the chemistry of flavours and fragrances. It is organized in four sections: flavours and fragrances of foodstuffs, essential oils and other natural products from plants, applied aspects of flavour and fragrance production and detection, analytical aspects of flavour and fragrance isolation and identification. It should be of interest to academic and applied scientists in the field of organic chemistry, phytochemistry, analytical chemistry and food science.

Many studies have been carried out on fragrances, flavors and perfumes worldwide. These products have important commercial value not only in India but in all over the world. Perhaps the most interesting results of the last few years in the fragrance and flavour fields are the many compounds described in this book. They may be used to engender or augment flavours in foodstuffs, chewing gums and medicinal products like mouthwash and toothpaste. The same compounds or closely related ones serve also to produce desirable aromas for perfumes, perfumed compositions such as soaps, detergents and cosmetics etc. Perfume is a mixture of fragrant essential oils and/or aroma compounds, fixatives, and solvents used to give the human body, animals, objects, and living spaces a pleasant scent. The odoriferous compounds that make up a perfume can be manufactured synthetically or extracted from plant or animal sources. Perfumes have been known to exist in some of the earliest human civilizations either through ancient texts or from archaeological digs. Modern perfumery began in the late 19th century with the commercial synthesis of aroma compounds, which allowed for the composition of perfumes with smells previously unattainable solely from natural aromatics alone. Flavors and Fragrances (F&F) are the essential ingredients that lend taste and smell, respectively, to food and personal or home care products. Without these, all the products that we use such as toffees, chips, toothpastes, soaps and shampoos, would be tasteless or odorless, boring, functional products. Fragrances are different types; floral, fruity, woody, flower, natural, etc. and has applications in different field; soap and toiletries, cosmetics, household applications etc. Flavoring in common language denote the combined chemical sensations of taste and smell, the same terms are usually used in the fragrance and flavors industry to refer to edible chemicals and extracts that alter the flavor of food and food products through the sense of smell. Applications of flavouring are in numerous field; meat, chocolate, dairy, beverage, confectionary, bakery, teas etc. Due to the high cost or unavailability of natural flavor extracts, most commercial flavorants are nature identical, which means that they are the chemical equivalent of natural flavors but chemically synthesized rather than being extracted from the source materials. Traditionally, while flavors and fragrances were viewed as the most customized of all raw materials, and therefore commanded higher prices, in the last decade, prices have been pushed down consistently by large manufacturers. This book basically deals with the roots and the evolution of perfumery, the part of hedonism, how perfumery is linked to the other fine arts, the art of composition, conclusion, introduction, fragrancing of functional products, line extensions, perfumery for household products, floral series : rose notes, jasmin notes, hyacinth notes, lilac and lily, orange blossom notes, tuberose notes, violet notes, mignonette, woody series: sandal notes, peppery notes, caryophyllaceous notes, introduction, aroma composition of various teas, flavory ceylon black tea, keemun black tea, green tea, pouchong tea and jasmine tea, lotus tea, soap manufacture, raw materials, shaving soap, transparent soaps, super fatted toilet soaps, the milling process, coloured soaps, perfumes, soap compounds, acacia, almond, almond soap, amber soap, buttermilk, brown windsor, carnation, chypre, cologne, cyclamen, fougere, heliotrope, hyacinth, jasmin, lavender, lilac, lily, etc. This book contains formulae and processes of various types of flavours, fragrances and perfumes. New entrepreneurs, technocrats, research scholars can get good knowledge from this book.
