Head of Jason Castro of Bates University (USA) used the standard data system on the map of characteristic odor of Andew Dravniek in 1985, which consists of 144 different odors. Using statistical methods, scientists combined odor descriptions to create similar types.

This method is similar to compressing a digital file, which is reduced in size but does not sacrifice the information needed, according to the Plos One report.

After obtaining impressive results, Mr. Castro's team is applying the method to establish a bank of chemical structures, to predict the smell of each chemical, especially useful for American manufacturers. Products.
