...current Engineering and Science Monthly, a Caltech flavor chemist, Hoiland-born Dr. Arie J. Haagen-Smit, tells how he vacuum-distilled 6,000 pounds of pineapples and ended up with a few grams of powerful pineapple essence. He took the essence apart bit by bit, identifying microscopic amounts of flavor-giving compounds. Then he mixed a cocktail of the chemicals he had spotted. The result was a "satisfactory reproduction" of fresh pineapple smell...
...Haagen-Smit did his laborious job for the Hawaiian pineapple growers, who believe that they can grow and market better pineapples if they know the chemical origin of the fruit's admired flavor. But Dr. Haagen-Smit's main interest is to find out what flavor really...
...Haagen-Smit believes that the shape of a compound's molecule is important in determining what it smells like. The nose, he thinks, contains "receptors" which are designed to respond to molecules of certain shapes. When one of these comes along, the receptor recognizes it by its shape, and sends a nerve message which the brain interprets as an odor...
...Haagen-Smit hopes that his work may develop into a new technique of flavor preservation. When vegetables are dehydrated, for instance, many of their volatile flavoring compounds are lost. After chemists have learned what these compounds are, they may be able to devise tricks for capturing and restoring the natural flavor to dehydrated food...
...Stanford and Caltech let out some preliminary details of an important discovery. At Stanford, Drs. Edward Lawrie Tatum and George Wells Beadle isolated in crystalline form one of two hormones by means of which Drosophila'?, genes control the fly's eye color. At Caltech, Dr. Arie Jan Haagen-Smit analyzed the hormone, found its molecule contained 21 atoms of carbon, 34 of hydrogen, two of nitrogen. 14 of oxygen. If the California scientists can follow up this first success by isolating and identifying the other eye-color hormone, they may cast a sudden brilliant light on how genes...
