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.

Instrumental measurements of the sensory quality of food and drink are of growing importance in both complementing data provided by sensory panels and in providing valuable data in situations in which the use of human subjects is not feasible. Instrumental assessment of food sensory quality reviews the range and use of instrumental methods for measuring sensory quality. After an introductory chapter, part one goes on to explore the principles and practice of the assessment and analysis of food appearance, flavour, texture and viscosity. Part two reviews advances in methods for instrumental assessment of food sensory quality and includes chapters on food colour measurement using computer vision, gas chromatography-olfactometry (GC-O), electronic noses and tongues for in vivo food flavour measurement, and non-destructive methods for food texture assessment. Further chapters highlight in-mouth measurement of food quality and emerging flavour analysis methods for food authentication. Finally, chapters in part three focus on the instrumental assessment of the sensory quality of particular foods and beverages including meat, poultry and fish, baked goods, dry crisp products, dairy products, and fruit and vegetables. The instrumental assessment of the sensory quality of wine, beer, and juices is also discussed. Instrumental assessment of food sensory quality is a comprehensive technical resource for quality managers and research and development personnel in the food industry and researchers in academia interested in instrumental food quality measurement.

The Springer Handbook of Odor is the definitive guide to all aspects related to the study of smell and their impact on human life. For the first time, this handbook aligns the senso-chemo-analytical characterization of everyday smells encountered by mankind, with the elucidation of perceptual, hedonic, behavioral and physiological responses of humans to such odors. From birth onwards we learn to interact with our environment using our sense of smell. Moreover, evolutionary processes have engendered a multi-faceted communication that is supported – even dominated – by olfaction. This compilation examines the responses of humans to odors at different stages of life, thereby building a foundation for a widely overseen area of research with broader ramifications for human life. The expert international authors and editor align aspects, concepts, methodologies and perspectives from a broad range of different disciplines related to the science of smell. These include chemistry, physiology, psychology, material sciences, technology but also disciplines related to linguistics, culture, art and design. This handbook, edited by an internationally renowned aroma scientist with the support of an outstanding team of over 60 authors, is an authoritative reference for researchers in the field of odors both in academia and in industry and is also a useful reference for newcomers to the area.

“I cannot recommend this fascinating book highlyenough.” –Simon Cotton, Chemistry & Industry,September 2014 “In conclusion: A comprehensive introduction to theworld of odours, not only for chemists.” –review inGerman: Monika Paduch, Gefahrstoffe - Reinhaltung Luft, October2014 A comprehensive overview of fragrance chemistry Fragrance materials are universal, from personal care productsto household cleaners, laundry products, and more. Although many ofthe scents themselves are synthesized in a lab, the actualmechanism of odour has long baffled chemists who attempt to modelit for research. In Chemistry and the Sense of Smell,industry chemist Charles S. Sell explores the chemistry and biologysurrounding the human detection and processing of odour, providinga comprehensive, single-volume guide to the totality of fragrancechemistry. The correlation between molecular structure and odour is muchmore complex than initially thought, and the intricacies of themechanism by which the brain interprets scent signals leaves muchto be discovered. This book provides a solid foundation offragrance chemistry and highlights the relationship betweenresearch and industry with topics such as: The analysis and characterization of odour The role scent plays in our lives The design and manufacture of new fragrance ingredients The relationship between molecular structure and odour The mechanism of olfaction Intellectual challenges and the future of the field Complete with illustrations that clarify difficult concepts andthe structures of the molecules under discussion, Chemistry andthe Sense of Smell is an all-inclusive guide to the science ofscent. For professionals in the fragrance industry or relatedfields, this book is one resource that should not beoverlooked.
