Abstract

The invention relates to a directed composite extraction method for a tobacco endogenous original fragrant substance, which comprises the following steps: 1) a water extraction method is adopted to extract polarity aroma substances from tobaccos in a directed manner; 2) a supercritical CO2 extraction method is adopted to extract nonpolar aroma substances from tobaccos in a directed manner; 3) an ethanol extraction method is adopted to extract moderate polarity and weak polarity aroma substances from tobaccos in a directed manner; 4) the polarity aroma substances, the nonpolar aroma substances and the moderate polarity and weak polarity aroma substances are mixed according to the mass ratio of 1000:(0.1-5):(1-50). According to the invention, tobacco leaves, cut tobaccos, tobacco powder with fine particles, cigarette ash, tobacco stems or other wastes generated during the tobacco processing process are used as tobacco raw materials, so that the waste materials are recycled and pollution to the environment is reduced; with adoption of the method, the quality of the reproduced tobaccos is improved, the fragrance is increased, the fragrant charm is promoted, the natural tobacco fragrance is set off, the dry sensation of cigarette smoke is reduced, the secretion of saliva or body fluid of cigarette smoke is enhanced, and the comfort level of cigarettes is improved.

Description

technical field [0001] The invention relates to the field of tobacco, in particular to a method for directional compound extraction of endogenous tobacco aroma substances. Background technique [0002] There are many chemical constituents in tobacco. Since the 1970s, due to the development of analytical testing techniques, chemical components in tobacco have been continuously discovered. Shi Hongzhi et al. reported in 2011 that there were 4,992 identified chemical components in tobacco leaves, of which more than 700 were related to tobacco aroma. The molecules of aromatizing substances in tobacco contain specific aromatizing functional groups such as -OH, -CO, -NH and -SH, which can produce different aromas with different stimuli to the sense of smell. According to the different functional groups of aroma substances, tobacco aroma substances can be divided into alcohols, acids, ketones, esters and terpenes. Tobacco aroma substances are mostly secondary metabolites, so the...
