A good method of teaching him to memorise the various fragrances is to group them in "families" or "series." In the case of the young people for whose training I was partly responsible, I restricted the number to 15 different series: Citrus, Rose, Orange, Flower, Jasmine, Violet-Iris, Anise-like, Herbal, Green, Spice, Woody, Tobacco, Fruity, Balsamic, Animal, and Leather. During the last two decades the role of heterocyclic compounds in food flavors has been reviewed by
several authors (18, 78, 79, 117-122). While furans (66), pyrroles (68), thiophenes (61), thiazoles (62, 63,
120), oxazoles (65, 57), Iactones (64), pyrazines (55, 56) and their reduced systems were periodically
treated, surprisingly, pyridines which are among the most widely distributed volatile flavor compounds
have not been described in detail (69). Therefore, the purpose of this review is to fill this gap.
