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, 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; 2 Extract 30 g, mix the two evenly and add to 10 kg of reconstituted tobacco leaf base sheet. Through sensory evaluation, compared with the control sample group, the aroma texture and aroma volume are improved, and the flue-cured tobacco aroma is clearer, more Be natural. The irritation and cleanliness are slightly reduced, and the moisturizing feeling remains good.

Embodiment 3

[0037] 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, 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; 2 Extract 20 g, mix the two evenly and add them to 10 kg of reconstituted tobacco leaf base sheet. Through sensory evaluation, compared with the control sample group, the aroma texture and aroma volume have improved compared with the control sample group, and the smoke aroma is more transparent and full Some, the sweetness is somewhat apparent, and the degree of stimulation and cleanliness is sli...

Abstract

The present invention relates to a kind of reconstituted tobacco leaf of compound tobacco aroma substance obtained by water-containing extraction method and supercritical CO2 extraction method. Take 40 kg of waste sub-soot and extract it with 200L water at 50°C for 1 hour, filter it, and concentrate the extract to a density of 1.2g. / mL, water extraction concentrated solution for later use; take 3kg of waste smoke powder and extract it with supercritical CO2, the extraction conditions are that the pressure of the extraction kettle is 25MPa, the extraction temperature is 40°C, the CO2 flow rate is 200L / hour, and the extraction time is 4 hours; The pressure of the separation tank is 5MPa, the separation temperature is 45°C, and 115g of extract is obtained after extraction; 10,000g of water extraction concentrate and 30g of supercritical CO2 extraction are taken, and the two are mixed evenly and added to 10kg of reconstituted tobacco leaf substrate. The invention improves the quality of the reconstituted tobacco leaves, increases the amount of aroma, enhances the aroma, sets off the natural aroma of smoke, reduces the dryness of smoke, enhances the feeling of body fluid in smoke, and improves the comfort of cigarettes.

Description

technical field [0001] The invention relates to the field of tobacco, in particular to a reconstituted tobacco leaf compounded with tobacco aroma substances obtained by an aqueous extraction method and a supercritical CO2 extraction method and a cigarette prepared therefrom. 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,...
