Abstract

By means of the electron-topologic approach suggested earlier, the structural and electronic features favouring meat odour occurrence are evaluated using 77 organic compounds with known odorant properties as a basis for primary logico-structural analysis. A general fragment of the type XH2 (where X = S, O, N is a hetero-atom) with a certain electronic structure and conformational property is shown to be responsible for the meat odour. The results obtained allow for a prognosis of odorant compounds and their purposeful synthesis.
