Your sense of smell distinguishes 10 different types of odors Bashny.Net

One of the first attempts to systematize the olfactory sensations, like taste, visual and sluhovym



Recently, scientists have suggested to divide all the smells that person is able to feel, ten main types. The classification is as follows: the fragrant smells of wood (including tar), fruit (except citrus), chemical, mint, sweet smells of popcorn, citrus, spicy scents and smells of decay.



According to one of the scientists who developed this concept, Jason Castro college Bates in Lewiston (Maine, USA), to classify the odors it was somewhat more complicated than, for example, taste, that there are four main types (in the eastern culture is traditionally allocate more and fifth taste - the so-called umami, which give the food free amino acids, such as glutamic).

To compile its classification Jason and his colleagues used the "Atlas of smells" Andrew Dravneka, published in 1985, the year. In the work described Dravnek 144 different odor using such characteristics and comparison, as "sweet", "flower", "distinct" and others. With the help of computer analysis, researchers calculate what combination of features found in the descriptions most often developed their own system of ten categories, trying at the same time that the system takes into account all the possible features of odors.

Now a team of researchers led by Castro solves the problem with the prediction of the properties of artificially created fragrances based on the chemical composition of substances that possess them. It is expected that the development of perfume companies interested.
