Embodiment 1

[0034] Take 40 kg of waste tobacco ash, stir and extract with 280L water at 40°C for 1 hour, filter, concentrate the extract to a density of 1.2 g / mL, take 10000 g of the water extract concentrate and add it to 10 kg of reconstituted tobacco leaf substrate as a control sample group.

Embodiment 2

[0036] Take 40kg of waste tobacco ash, stir and extract with 200L of water at 50℃ for 1 hour, filter, concentrate the extract to a density of 1.2g / mL, and use the water-extracted concentrate for use; take 3kg of waste tobacco dust with supercritical CO 2 For extraction, the extraction conditions are: the pressure of the extraction kettle is 25MPa, the extraction temperature is 40℃, and the 2 The flow rate is 200L / hour, the extraction time is 4 hours; the pressure of the separation kettle is 5MPa, the separation temperature is 45°C, 115g of extract is obtained after extraction; 10000g of water extract concentrate and supercritical CO 2 Extract 30g, mix the two evenly and add them to 10kg reconstituted tobacco substrate. Through sensory evaluation, the aroma texture and aroma volume are improved compared with the control sample group, and the aroma of flue-cured tobacco is clearer and more natural. . The degree of irritation and cleanliness decreased slightly, and the moisturizing ...

Embodiment 3

[0038] Take 40kg of waste soot and extract with 200L of water at 40℃ for 1 hour, extract twice, filter, and concentrate the extract to a density of 1.1g / mL, and use the water-extracted concentrate for use; take 6kg of waste soot with supercritical CO 2 For extraction, the extraction conditions are: the pressure of the extraction kettle is 20MPa, the extraction temperature is 35℃, and the 2 The flow rate is 180L / hour, the extraction time is 3 hours; the pressure of the separation kettle is 5.5MPa, the separation temperature is 40℃, and 265g of extract is obtained after extraction; 10000g of water extract concentrate and supercritical CO 2 Extract 20g, mix the two evenly and add them to 10kg reconstituted tobacco base. Through sensory evaluation, the aroma texture and aroma volume are improved compared with the control sample group, and the tobacco aroma is more transparent and fuller. Some sweetness appears, stimulation and cleanliness are slightly reduced.

Abstract

The invention relates to a method for directional and compound extraction of aroma-inducing substances in tobacco from tobacco raw materials by water extraction and supercritical CO2 extraction. The steps are as follows: 1) directional extraction of polar aroma-inducing substances from tobacco by water extraction; 2) The supercritical CO2 extraction method is used to extract non-polar aroma substances from tobacco; 3) the above-mentioned polar aroma substances and non-polar aroma substances are mixed, and the formula ratio is 1000:0.1-5. 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 in the tobacco processing process. "Turning waste into treasure" reduces the pollution to the environment; Concentrated liquid and tobacco supercritical CO2 extract are blended in appropriate ratio, and the compound flavoring spices are sprayed into the reconstituted tobacco leaves to improve the quality of reconstituted tobacco leaves, increase the aroma, enhance the aroma, set off the natural smoke aroma, and reduce the smoke. The dry feeling of the gas, the enhancement of the body fluid feeling of the smoke, and the improvement of the comfort of the cigarette.

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...
