Abstract
In order to optimize the supercritical CO2 extraction conditions for Hongda tobacco essence, the extraction yield was investigated by L9 ( 34 ) orthogonal experiment, and the volatile components in the obtained extracts were analyzed by GC/MS, and the essence was applied into cigarette as a flavor.The results of the experiments indicated that the optimal extraction pressure, temperature, CO2 flow rate and time were 30 MPa, 45 ℃ , 25 kg/h and 2.0 hours, respectively.Thirty-six components were identified, and the main volatile components were; 12 - isopropyl - 1, 5, 9 - trimethyl - 4, 8, 13 - cyclotetradecatriene -1,3- diol (21.28％ ) , nicotine ( 15.88％ ) , octadecyne (6.70％ ) , 2, 5 - epoxydihydroretroionone (4.49％ ) , Iedol (3.59％ ) , 1 -methyl -4 - (2 - methyloxiranyl) -7 - oxabicyclo[4.1.0]heptane (2.42％ ), ascaridole (2.32％ ) , benzenamine (2.20％ ) , 4H - cyclopenta[def]phenanthrene (2.00％ ).The sensory evaluation showed that the essence obviously enhanced tobacco' s natural aroma, and imparted a unique stylish character to tobacco.The optimized parameters increase the yield of essence, and the extraction process is feasible and stable.关键词
