Embodiment 1

[0033] Take 40kg of waste soot and extract it with 280L of water at 40°C for 1 hour, filter, concentrate the extract to a density of 1.2g / mL, take 10,000g of water-extracted concentrate, and add it to 10kg of reconstituted tobacco leaf substrate as a control sample group.

Embodiment 2

[0035] Take 40kg of waste soot, stir and extract with 200L water at 50°C for 1 hour, filter, concentrate the extract to a density of 1.2g / mL, and extract the concentrated solution with water for later use; 2 Carry out extraction, extraction condition is that extraction pot pressure is 25MPa, and extraction temperature is 40 ℃, CO 2 The flow rate is 200L / hour, and the extraction time is 4 hours; the pressure of the separation tank is 5 MPa, the separation temperature is 45°C, and 115g of extract is obtained after extraction; 10kg of waste soot is taken with 40L of 80% ethanol at 50°C, and the extraction time is 2 hours. Extracted twice, the extract was concentrated to a density of 1.2 g / mL; 2 30 g of extract and 200 g of ethanol extract concentrate were mixed evenly and added to 10 kg of reconstituted tobacco leaf base sheet. Through sensory evaluation, compared with the control sample group, the aroma texture and aroma volume were improved compared with the control sample grou...

Abstract

The invention relates to an endogenous natural tobacco aroma substance extracted in a directional and combined manner. The substance comprises a polar aroma substance directionally extracted from tobacco by a water extraction method, a nonpolar aroma substance directionally extracted from the tobacco by a supercritical CO2 extraction method and moderate-polarity and weak-polarity polar substances directionally extracted from the tobacco by an ethanol extraction method, wherein the mass ratio of the polar aroma substance to the nonpolar aroma substance to the moderate-polarity and weak-polarity polar substances is 1000: (0.1-5): (1-50). According to the tobacco aroma substance, the used tobacco raw materials are tobacco leaves, cut tobaccos or wastes, such as tobacco powder, tobacco ash or tobacco stems of tiny grains, generated during tobacco processing, so that the waste is changed into the valuable, and the pollution to the environment is reduced; the tobacco aroma substance has the advantages that the quality of reconstituted tobacco is improved, the aroma amount is increased, the aroma charm is improved, the natural tobacco aroma is set off, the smoke dryness is lowered, the smoke-induced saliva secretion feeling is enhanced, and the degree of comfort of cigarette is increased.

Description

technical field [0001] The invention relates to the field of tobacco, in particular to an endogenous tobacco aroma substance extracted through directional compound extraction. 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...
