Embodiment 1

[0031] 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 10000g of the concentrated solution with water, and add it to 10kg of reconstituted tobacco leaf substrate as a control sample group.

Embodiment 2

[0033] 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 5MPa, the separation temperature is 45°C, and 115g of extract is obtained after extraction; 2 Extract 30g, mix the two evenly and add to 10kg of reconstituted tobacco leaf base sheet. Through sensory evaluation, compared with the control sample group, the aroma texture and aroma volume are improved compared with the control sample group, and the flue-cured tobacco aroma is clearer and more natural. . The irritation and cleanliness are slightly reduced, and the moisturizing feeling remains good.

Embodiment 3

[0035] 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 5.5MPa, the separation temperature is 40°C, and 265g of extract is obtained after extraction; 2 Extract 20g, mix the two evenly and add to 10kg of reconstituted tobacco leaf base sheet. Through sensory evaluation, compared with the control sample group, the aroma texture and aroma volume are improved compared with the control sample group, and the smoke aroma is more transparent and full. The sweetness is somewhat apparent, and the degree of stimulation and cleanliness is slightly reduced....

Abstract

The invention relates to a composite tobacco aroma substance extracted by water extraction method and supercritical CO2 extraction method. The composite tobacco aroma substance is a polar aroma substance extracted from tobacco by water extraction method and supercritical CO2 extraction method The non-polar aroma-inducing substances are directional extracted from tobacco, and the formula ratio of the polar aroma-inducing substances and the non-polar aroma-inducing substances 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 composite tobacco aroma-inducing substance obtained by 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 substan...
