Aroma Science

This text is based on lecture notes and handouts compiled by the author for students taking a course in aroma chemistry as part of a Master's Degree in cosmetic science at Fairleigh Dickinson University, USA. It is intended to teach the science involved in the study of aroma materials and their effect on society. Examples and problems are provided and explained and additional problems with answers are available for study and review. The first section deals with odour sensations, the correlations of odours and molecular structures and the properties, sources and uses of natural aroma materials. The second part deals with synthetic aroma products - the sources, properties, uses and syntheses of such aroma compounds as aromatics, heterocyclics, aliphatics, alicyclics and terpenes. The third section is on aroma analytical methods and describes the procecures used for the evaluation and identification of aroma compounds. The final section is on aroma applications and deals with the creation of perfumes, the applications of fragrances in cosmetic formulations, and the ageing and stability of aroma compounds and their use as therapeutic agents.
