Informationen zum Autor Dr. Andreas Herrmann is a research chemist at Firmenich SA, an international flavour and fragrance company, in Genève (Switzerland), working on the development of new fragrance delivery systems. He has published a series of research papers on the chemical release of volatiles under mild reaction conditions. He is the author or co-author of about 30 scientific publications and 10 international patent applications. Klappentext Volatile compounds are molecules with a relatively low molecular weight allowing for efficient evaporation into the air. They are found in many areas of everyday life: they are responsible for the communication between species such as plants, insects or mammals; they serve as flavours or fragrances in many food products or perfumed consumer articles and they play an important role in atmospheric chemistry. The Chemistry and Biology of Volatiles takes an interdisciplinary approach to volatile molecules. Review-style introductions to the main topics in volatile chemistry and biology are provided by international experts, building into a broad overview of this fascinating field. Topics covered include: volatiles - an interdisciplinary approach biosynthesis and emission of isoprene, methylbutanol and other volatile plant isoprenoids analysis of the plant volatile fraction plant volatile signalling: multitrophic interactions in the headspace pheromones in chemical communication use of volatiles in pest control challenges in the synthesis of natural and non-natural volatiles the biosynthesis of volatile sulphur flavour compounds thermal generation of aroma-active volatiles in food human olfactory perception perfumery - the wizardry of volatile molecules microencapsulation techniques for food flavour profragrances and properfumes reactions of biogenic volatile organic compounds in the atmosphere The Chemistry and Biology of Volatiles is an essential overview of this important field for students and researchers in organic and bioorganic chemistry, biochemistry, flavour and fragrance research, pest control, olfactory perception, and atmospheric chemistry. Zusammenfassung "Coming to a conclusion, this wonderful, informative and very interesting book presents an excellent overview of small volatile organic compounds and their role in our life and environment. Really fascinating is the entirety of scientific disciplines which were addressed by this book.
