This book is designed to give the reader up to date infonnation on some of the more exciting developments that have taken place at the leading edge of fragrance and flavour research. Chapter one gives the reader a rnpid excursion through the chronological landmarks of fragrance and flavour materials and sets the scene for the remaining nine chapters which cover topics that are at the forefront of modem research. Chapter two looks at the total synthesis of synthetically interesting perfumery naturnl materials. This chapter aims to highlight the creative and elegant chemistry that has been performed by some of the worlds greatest chemists in their quest to synthesise one of the five naturnl products reviewed in the chapter. The chapter fits in with the forward looking theme of the book as it will hopefully inspire other chemists that are interested in synthesising natural products to produce elegant new, or industrially applicable routes to these and other perfumery materials. Chapter three looks at the growing area of interest in asymmetric fragrance materials. The chapter focuses on the use of the metal-BINAP catalytic system for the preparation of fragrance and flavour ingredients. Environmental considerations are now an integrnl and vital part of planning any new industrial chemical process. Chapter four aims to give the reader an insight into the wide-ranging and often readily applicable chemistry that is currently available for the installation of environmentally friendly chemical processes.

Smell and Taste - the chemical senses. They carry meaning to perceive and evaluate reality, but also evoke memories, feelings, and desires. They allow us to dream, to explore our emotions, or to seduce: 'A woman should wear her perfume wherever she wants to be kissed' advised Coco Chanel. The power of olfactory sensations seems almost magical to us - the chemistry behind these, however, is no mystery. The current topics of flavor and fragrance research are compiled in this book, which comprises 28 articles of the talks presented at the 2007 RSC/SCI 'Flavours and Fragrances' conference held at the Imperial College in London. The scope is intentionally broad and ranges from natural products to fragrance chemistry, to perfumery and olfaction, to foods and flavors. Chemistry is, however, the central and unifying discipline.

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.

This book is an introduction to the world of aroma chemicals, essential oils, fragrances and flavour compositions for the food, cosmetics and pharmaceutical industry. Present technology, the future use of resources and biotechnological approaches for the production of the respective chemical compounds are described. The book has an integrated and interdisciplinary approach on future industrial production and the issues related to this topic.

This book is the Proceedings of the 12th International Flavor Conference, 4th George Charalambous Memorial Symposium, held May 25-29, 2009 in Skiathos, Greece. The International Flavor Conferences are sponsored by the Agricultural Food Chemistry Division of the American Chemical Society and are attended by leaders in the in the field of flavor and food chemistry. The International Flavor Conferences have been held as a global forum for leaders in the field of flavor and food chemistry to present their results covering recent research activities. As in previous years the conference stresses flavors as its main theme but also includes important topics in food chemistry (analytical methods, packaging storage) and production (safety, patents). Information gathered by researchers in food chemistry have found numerous practical applications for improving foods, and symposia such as this have a goal of transferring basic knowledge to finished products. Recent Advances in Food and Flavor Chemistry: Food Flavors and Encapsulation, Health Benefits, Analytical Methods, and Molecular Biology of Functional Foods will be a useful reference for researchers and other professionals in the industry and academia, particularly those involved directly in food science. This book covers several topical areas and includes: -A historical look at the use of isotopic analyses for flavour authentication -Computer-aided organic synthesis as a tool for generation of potentially new flavouring compounds from ascorbic acid -Butter flavors and microwave popcorn: A review of health issues and industry actions -The aroma of guavas - Key aroma compounds and influence of tissue disruption -Flavour release in lipid rich food matrices; in vitro and in vivo measurement using proton transfer reaction mass spectrometry -A study of the fate of aspartame and flavour molecules in chewing gum utilizing LC/MS/MS and GC/MS -Study on the interaction of selected phenolic acids with bovine serum albumin.

Food flavour technology is of key importance for the food industry.Increasingly, food products must comply with legal requirements andconform to consumer demands for “natural” products, butthe simple fact is that, if foods do not taste good, they will notbe consumed and any nutritional benefit will be lost. Thereis therefore keen interest throughout the world in the production,utilisation and analysis of flavours. The second edition of this successful book offers a broadintroduction to the formulation, origins, analysis and performanceof food flavours, updating the original chapters and addingvaluable new material that introduces some of the newermethodologies and recent advances. The creation of flavourings is the starting point for the book,outlining the methodology and constraints faced byflavourists. Further constraints are considered in a chapterdealing with international legislation. The origins of flavours aredescribed in three chapters covering thermal generation,biogeneration and natural sources, keeping in mind the adjustmentsthat manufacturers have had to make to their raw materials andprocesses to meet the demand for natural products whilst complyingwith cost issues. Delivery of flavours using encapsulation orthrough an understanding of the properties of the food matrix isdescribed in the next two chapters, and this section is followed bychapters describing the different ways to analyse flavours usinginstrumental, modelling and sensory techniques. The book is aimedat food scientists and technologists, ingredients suppliers,quality assurance personnel, analytical chemists andbiotechnologists.

Scent and Chemistry Odor impressions have cast a spell over mankind since the dim and distant past. But even today, we are –consciously or subconsciously– guided by our sense of smell and the chemistry behind it. The prominent fragrance chemists Günther Ohloff, Wilhelm Pickenhagen and Philip Kraft convey the scientist, the perfumer, and the interested layman with a vivid and up-to-date picture of the chemistry of odorants and the research in odor perception. In this second thoroughly revised and updated edition they are joined by creative perfumer Fanny Grau, a rising master in this métier, who complements the scientific treatise by a concise introduction to the art of perfumery and its composition techniques. Besides this new chapter on the creative aspects of perfumery, the book details on the molecular basis of olfaction, olfactory characterization of perfumery materials, structure–odor relationships, the chemical synthesis of odorants, and the chemistry of essential oils and odorants from the animal kingdom, backed up by many perfume examples and historical aspects. It will serve as a thorough introductory text for everyone interested in the molecular world of odors.
