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.

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.

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.

Qualitative odor-structure relationships have been applied for more than a century. The results of these studies are mostly the consequence (outcome) of the application of common sense gathered by experience. Two main features characterize the molecular structures of odorant molecules: “electronicity” (electronic charge distribution over a molecule) and “stereocity” (volume, shape and profile of a molecule).

Citrus peel oils are of great importance for the flavor and fragrance industry because they are widely used in perfumes, beverages, food and cosmetic products. Many publications cover the analysis of the volatile substances of peel oils. Nevertheless, the non-volatile ingredients seem to play an important role in citrus oils, too.

Understanding how aroma compounds interact with and are released from simple and complex foods. Flavors and fragrances usually are complex mixtures of molecules with different physical properties, including volatility, fat solubility and sensorial characteristics, covering a wide spectrum of threshold values. They are usually present in natural extracts or final products at levels in the order of ppb to ppm.
