Preparation method of high-aroma low-nicotine tobacco shreds

The invention discloses a preparation method of high-aroma low-nicotine tobacco shreds. The preparation method comprises the following steps: extracting tobacco shreds with a non-polar solvent, a weak-polar solvent, a medium-polar solvent and a polar solvent in sequence, removing solvents from extract solutions of the non-polar solvent, the weak-polar solvent and the medium-polar solvent, respectively backfilling the extracted tobacco shreds with the extract solutions, and performing cut tobacco drying/fluidized drying to obtain the high-aroma low-nicotine tobacco shreds. According to the method, the aroma quality of the tobacco shreds is ensured while the nicotine content is reduced. 本发明公开了一种高香气低烟碱烟丝的制备方法，包括如下步骤：将烟丝先后经非极性溶剂、弱极性溶剂、中等极性溶剂和极性溶剂提取，再将非极性溶剂、弱极性溶剂、中等极性溶剂的提取液除去溶剂后，分别回填至提取后的烟丝，然后经烘丝/流化干燥，即得到高香气低烟碱烟丝。本发明的方法降低烟碱含量的同时确保了烟丝的香气品质。
