    摘要: Process for extracting nicotine is disclosed in which tobacco is exposed to an extracting solvent in either liquid or gaseous state at temperatures below about 100.degree. C. and at high pressures. The aroma generating substances can be removed by conducting the extraction with the tobacco in dry condition. Thereafter the tobacco can be moistened, and on further contacting the nicotine is removed. The aroma generating substances can then be recombined with nicotine free tobacco.
