The beginning of a career, discovery of new materials and creating the scent of gardenia. An Education in Raw Materials. At the time I was beginning my career, bureaucracy loomed over the horizon, though the hysteria of the time cannot compare to today.

The misconceptions and popularity surrounding vanilla. In 2002, a pair of astronomers from Johns Hopkins University believed that they had discovered that, after averaging the colors from 200,000 galaxies, taken as a whole the universe is green. However, three months later, the researchers decided that in fact the universe is “actually a very pale beige, almost vanilla white.

It has long been known that optically active stereoisomers—optical antipodes or enantiomers—can have different sensory qualities. The most illustrative examples of this phenomenon are the enantiomers of carvone and menthol.
Especially during the last decade the interest in the separation and determination of the sensory properties of natural enantiomers has resulted in a large number of publications. This increasing interest was initiated by the development of new chromatographic separation techniques on optically active stationary phases and arose from the need to prove the naturalness of certain enantiomers. Numerous enantiomers have already been isolated and/or synthesized and their sensory properties have been investigated. These sensory properties of the compounds concern their odor qualities and threshold values in certain media. Because the determination of the sensory properties is a rather subjective task due to intra- and inter-individual differences, it is not suprising that some confusion exists about these properties. The sensory properties of a series of volatile enantiomers, which are important in flavors and fragrances, will be discussed in this article.
