ABSTRACT


Changes of viscosity of 40% aqueous ethanol (vodka) flavored
with commercially available essences of vanilla, lemon, orange, rum, and cream
applied at concentration of 0.1 and 0.5 w% had no effect upon the macrostructure
of vodka. These admixtures changed solely the flavor of that drink. Such result
was confirmed by changes of the NMR spin-lattice, T1, and spin-spin,
T21 and T22 relaxation times and computer simulations of
the energy of interactions of the molecules of particular essences in aqueous
solutions of ethanol of varying concentration.

Key words: cream essence, computer simulations, lemon essence, mouth feel, orange essence, relaxation times, rum essence, vanilla essence, viscosity.
