Abstract: Mint sub-oil encapsulated into microcapsules can effectively preclude its volatilization. Mint sub-oil microcapsules were prepared with solvent dehydration and phase separation-coacervation. The colorimetry analysis showed that mint sub-oil content in solvent dehydration microcapsules and in phase separation-coacervation micrcxapsules was about 11.3% and 15.8%, respectively. Cigarettes treated with the solvent dehydration microcapsuies delivered about 0. 502mg mint sub-oil in TPM/cig. and had a pleasing mint flavor.
