Research article: Biotransformation of Unsaturated Aliphatic Aldehydes Using Baker’s Yeast
By: Ian Gatfield and Heinz-Jürgen Bertram
Actively fermenting baker’s yeast (Saccharomyces cerevisiae) not only converts aliphatic aldehydes to the corresponding alcohols, but also may reduce certain carbon-carbon double bonds in the same molecule. Furthermore, an in situ acyloin condensation reaction occurs; this bioconversion reaction gives rise to relatively good yields of unsaturated 2,3-diols, which have two carbon atoms more than the corresponding aliphatic aldehyde used as substrate. Baker’s yeast has been used as a reagent in organic synthesis since the beginning of the 20th century, when fundamental studies were initiated on the mechanism of formation of fusel alcohols from the corresponding l-amino acids during the formation of ethanol.

A Mathematical Model For Odors Applied To Binary Odor Mixtures
By: Francis Maurin
This expanded mathematical model is a modification of Berglund’s model (1973).1 The modification explains the elimination of one odor by another, the synergy of odors of low intensity and the existence of odorless substances, which have deodorant properties.

Schiff Bases — A Primer
By: Conrad Schmidt
The flavor and fragrance industry uses many classes of chemicals, including a number that otherwise are encountered only rarely outside of organic chemistry textbooks. A good example is Schiff bases, named for their discoverer, German chemist Hugo Schiff (1834-1915). A Schiff base, along with by-product water, is formed by reaction of an aldehyde with a primary amine.

Industry Insight: The Provocative Emperor of Scent
By: Jeb Gleason-Allured, Editor
Chandler Burr, after a chance encounter with Luca Turin — a biophysicist possessing a gift for distinguishing the components of a scent — set out to write a story about Turin and his theory that the nose deciphers smell by using vibrations rather than the shape of molecules. As his investigation begins, Burr’s simple story about the creation of a scientific theory quickly takes readers to the heart of the fragrance industry and the scientific publishing world.
