Embodiment 0

[0028] 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 1

[0030] Take 40kg of waste soot and extract it with 200L of 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; take 10kg of waste soot and use 40L of 80% ethanol at 50°C for 2 hours, extracted twice, and concentrated the extract to a density of 1.2 g / mL; took 10,000 g of water extract concentrate and 300 g of ethanol extract concentrate, mixed them evenly, added them to 10 kg of reconstituted tobacco leaves, and smoked them through sensory evaluation. Compared with the control sample group, the aroma transparency and brightness are slightly better, with a slightly sweet aroma, the smoke has a certain softness, the concentration is medium +, there are floating thorns in the mouth, and the aftertaste is slightly astringent.

Embodiment 2

[0032] 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 1.2g / mL, and extract the concentrated solution with water for later use; take 10kg of waste soot and use 80L of 60% ethanol at 70°C, The extraction time was 1 hour, and the extraction was performed once, and the extract was concentrated to a density of 1.2 g / mL; 10,000 g of water extraction concentrate and 200 g of ethanol extraction concentrate were mixed evenly and added to 10 kg of reconstituted tobacco leaves. Smoking evaluation, compared with the control sample group, the aroma transparency is slightly better, the smoke concentration is medium +, it is still delicate and agglomerated, there are floating thorns in the mouth, slightly woody, and the aftertaste is slightly astringent.

Abstract

The invention relates to an intrinsic tobacco aroma substance directionally and compositely extracted from a tobacco raw material by a water extraction method and an ethanol extraction method. The substance comprises water-extracted polar aroma substances and ethanol-extracted neutral and weakly polar aroma substances which are mixed with one another. The mass ratio of the polar aroma substances to the neutral and weakly polar aroma substances is 100:0.1-5. The intrinsic tobacco aroma substance has the advantages that the tobacco raw material is fine-grained waste such as tobacco powder, tobacco ash or tobacco stems which are generated in tobacco leaf, tobacco shred or tobacco processing procedures, accordingly, 'the waste is turned into wealth', and environmental pollution is reduced; water extraction concentrated solution for tobacco and ethanol extraction concentration solution are properly proportionally blended and are compounded with aroma materials to generate a mixture, the mixture is added into tobacco products such as reconstituted tobacco leaves, accordingly, the sensory quality can be improved, the aromatic quantity can be increased, the aromatic note can be enhanced, natural tobacco aroma is highlighted, the dry sensation of smoke of the tobacco is reduced, secretion sensation of the smoke of the tobacco can be improved, and the smoking comfort can be enhanced.

Description

technical field [0001] The invention relates to the field of tobacco, in particular to an aroma substance in tobacco obtained by directional compound extraction of the aroma substance in tobacco. 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 secon...
