Abstract

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.

Description

technical field [0001] The invention belongs to the field of cigarette processing, and in particular relates to a preparation method of shredded tobacco with high aroma and low nicotine. Background technique [0002] With the improvement of people's health awareness, the intensity of tobacco control at home and abroad has been continuously strengthened, and the development of low-nicotine and low-harm cigarette products has become a trend. Nicotine is an important chemical component that affects the sensory quality of cigarettes, and it is also considered a key factor in smoking addiction and a pathogenic factor in many smoking-related diseases. Reducing the content of harmful substances in tobacco and tobacco products, especially nicotine, has become an important direction of tobacco research. [0003] Extracting nicotine from shredded tobacco is an important method to reduce nicotine content. Currently, nicotine extraction methods mainly include water extraction, organic...
