Current Topics in Flavor and Fragrance Research


Book Description

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.




Current Topics in Flavours and Fragrances


Book Description

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.

Chemistry and Technology of Flavours and Fragrances


Book Description

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.

Scent and Chemistry


Book Description

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.




Common Fragrance and Flavor Materials


Book Description

Get a good start in flavor and fragrance chemistry! This book presents a survey of those natural and synthetic fragrance and flavor materials which are commercially available, produced and used on a relatively large scale and which are important ingredients for the creation of fragrance and flavor compositions because of their specific sensory characteristics, e.g., smell, taste. It provides information on their properties, methods employed in their manufacture, and their areas of application. This is the 5th edition of the classic "Bauer-Garbe". '...The excellent and concise introduction to this unique industry is followed by extensive information on nearly 500 of the most used fragrance and flavor compounds. Names, molecular formula, physical data, odor and flavor descriptions, uses, and a number of processes for the larger scale production of chemicals are all included. Successive chapters deal with essential oils, animal secretions, quality control, toxicology and literature. The formula, name and CAS registry number index are an invaluable and timely addition.' - Parfumer and Flavorist '...Data that would normally have to be selected from many different books are available in one source with this book...with over 800 citations throughout the text, this is a nearly inexhaustible source of information.' - Euromaterials

Science and Technology of Aroma, Flavor, and Fragrance in Rice


Book Description

With contributions from a broad range of leading researchers, this book focuses on advances and innovations in rice aroma, flavor, and fragrance research. Science and Technology of Aroma, Flavor, and Fragrance in Rice is specially designed to present an abundance of recent research, advances, and innovations in this growing field. Aroma is one of the diagnostic aspects of rice quality that can determine acceptance or rejection of rice before it is tested. Aroma is also considered as an important property of rice that indicates its preferable high quality and price in the market. An assessment of known data reveals that more than 450 chemical compounds have been documented in various aromatic and non-aromatic rice cultivars. The primary goal of research is to identify the compounds responsible for the characteristic rice aroma. Many attempts have been made to search for the key compounds contributing to rice aroma, but any single compound or group of compounds could not reported that are fully responsible. There is no single analytical technique that can be used for investigation of volatile aroma compounds in rice samples although there are currently many technologies available for the extraction of rice volatile aroma compounds. These technologies have been modified from time to time according to need, and many of them are helping the emergence of a new form, particularly in the distillation, extraction, and quantification concept. This new volume helps to fill a void in the research by focusing solely on aroma, flavor, and fragrance of rice, helping to meet an important need in rice research and production. Key features of this volume: • provides an overview of aromatic rice from different countries • looks at traditional extraction methods for chemicals associated with rice aroma, flavor, and fragrance • presents new and modern approaches in extraction of rice aroma chemicals • explores genetic engineering for fragrance in rice
