Embodiment 1

[0037] 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

[0039] 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...

Embodiment 3

[0041] Take 40kg of waste soot, stir and extract with 200L water at 40°C for 1 hour, extract twice, filter, concentrate the extract to a density of 1.1g / mL, and extract the concentrated solution with water for later use; take 6kg of waste and soot with supercritical CO 2 Carry out extraction, extraction condition is that extraction pot pressure is 20MPa, and extraction temperature is 35 ℃, CO 2 The flow rate is 180L / hour, and the extraction time is 3 hours; the pressure of the separation tank is 5.5 MPa, the separation temperature is 40°C, and 265g of extract is obtained after extraction; 10kg of waste soot is taken with 80L of 60% ethanol at 70°C, and the extraction time is 1 hour. Extract once, concentrate the extract to a density of 1.2 g / mL; take 10,000 g of the concentrated solution in water, 2 20 g of extraction and 150 g of ethanol extraction concentrate were mixed evenly and added to 10 kg of reconstituted tobacco leaf base sheet. Through sensory evaluation, compared w...

Abstract

The invention relates to a method for directional composite extraction of tobacco endogenous aroma substances, the steps are as follows: 1) water extraction method to directional extract polar aroma substances from tobacco; 2) supercritical CO2 extraction method to directional extract non-toxic substances from tobacco Polar aroma substances; 3) The ethanol extraction method extracts medium polar and weak polar aroma substances from tobacco; 4) Combines polar aroma substances, non-polar aroma substances and medium polar and weak aroma substances The aroma-inducing substances are formulated according to the mass ratio formula of 1000:0.1-5:1-50. The tobacco raw materials used in the present invention are wastes such as tobacco leaves, shredded tobacco or fine particle tobacco dust, soot or tobacco stems produced during tobacco processing. "Turning waste into treasure" reduces environmental pollution; the present invention improves the efficiency of reconstituted tobacco leaves. Quality, increase the amount of aroma, enhance the aroma, set off the natural aroma of smoke, reduce the dryness of smoke, enhance the sense of body fluid in smoke, and improve the comfort of cigarettes.

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...
