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.

Qualitative Analysis of Flavor and Fragrance Volatiles by Glass Capillary Gas Chromatography deals with the application of glass capillary gas chromatography to qualitative analysis of flavor and fragrance volatiles. Topics range from gas chromatographic system requirements and retention indices to selective detectors, ancillary reactions, and gas chromatography-mass spectrometry. This text is comprised of six chapters; the first of which provides an overview of the use of glass capillary gas chromatography in qualitative analysis of flavor and fragrance volatiles. The discussion then turns to gas chromatographic system requirements with respect to columns, inlets, detectors, and temperature control. The reader is also introduced to the Kovats retention index system, which utilizes a logarithmic scale to describe the retention behavior of a compound relative to that of the n-paraffin hydrocarbons. The use of selective detectors, such as thermal conductivity, flame ionization, nitrogen-phosphorus, electron capture, and photoionization detectors in qualitative analysis, is also considered. The final two chapters focus on ancillary reactions in glass capillary gas chromatography and general considerations in gas chromatography-mass spectrometry, including interfacing. This book is intended primarily for researchers involved in studies of the volatile constituents of fragrances, food, and natural products.

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.

With the development of synthetic organic chemistry techniques in the early 19th century the world of synthetic F&F materials began and expanded, but it has not totally replaced natural F&F. A growing segment of the public prefers natural foods to foods containing artificial additives, and will pay a premium for natural foods. While modern synthetic methods permit the economical production of artificial F&F on a large scale, the natural F&F industry remains important. Why is this so? How do the chemical, biological, and agricultural sciences support the natural F&F industry? What is the state of current natural F&F research? These are questions this volume attempts to address. Even considering only the value of F&F derived from essential oils, natural F&F constitute approximately a $2 billion annual business. The impact of F&F is best appreciated when you consider that a flavor or fragrance typically contributes only a very small part, both in cost and volume, to a finished product. Many analytical tools available do not have a detector that is as sensitive to taste or odor as a human (or many animals for that matter). The challenge for researchers is to sift F&F information from all the data obtained from the various analytical techniques. The intent of this book is to give the reader and appreciation for the many facets of the chemistry, analysis and production of natural flavors and fragrances. It is a field where each one of us who can smell and taste are active participants. New foods, plants, processes, packages and aromas are developed each day. Keeping researchers abreast of the many new facets of the natural F&F field have led to development of this chapter and the ACS symposium that served as the basis of this book.

This 6th edition is thoroughly revised and updated, and now additionally includes all commercially important flavor and fragrance materials that entered the market over the past 10 years. In one handy and up-to-date source, this classic reference surveys those natural and synthetic materials that are commercially available, produced, and used on a relatively large scale, covering their properties, manufacturing methods employed, and areas of application. For this new edition the chapter on essential oils has been completely revised with regard to production volumes, availability, and new product specifications, while new legal issues, such as REACH regulation aspects, are now included. Finally, the CAS registry numbers and physicochemical data of over 350 single substances and 100 essential oils have been updated and revised.

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.
