Problems solved by technology

Flavors with low boiling points are easily volatilized and lost during the drying stage when applied to the tobacco substrate, and the aroma imparting effect is not good
For example, menthol, a spice, can reduce the acrid gas and reduce the residue on the tongue when smoking cigarettes; leaf alcohol can provide a delicate fragrance and a natural feeling, and can cover up the coarse gas; phenylethyl alcohol can coordinate the aroma of cigarettes and increase the aroma of cigarettes However, when these alcoholic flavoring monomers are directly used for flavoring tobacco sheets, they will be easily volatilized and lost during the drying process and subsequent storage stages, and the aroma will not last.

Embodiment 1

[0061] Mix 1.56g of L-menthol, 1.48g of dihydrocoumarin, 20mg of p-toluenesulfonic acid and 50mL of n-hexane in a 100mL single-necked bottle, and stir at 70°C for 2h. GC-MS detection reaction progress. After the reaction was completed, it was left to stand overnight, and 1.90 g of a crude solid product was obtained by suction filtration, with a chromatographic purity of 92%. The yield was 75%. The crude product was recrystallized once with n-hexane to obtain menthyl 3-(2-hydroxyphenyl)propionate with a chromatographic purity of 98%. The melting point is 83-84°C, and its mass spectrum is shown in the attached picture figure 1 .

[0062] Thermal cracking analysis of menthyl 3-(2-hydroxyphenyl)propionate, at 200°C, the cracking products are menthol and dihydrocoumarin, see attached picture figure 2 .

[0063] The thermogravimetric analysis of 3-(2-hydroxyphenyl)menthyl propionate shows that the latent aroma begins to crack at around 120°C, and gradually vaporizes as the tem...

Embodiment 2

[0069] Using a method similar to that of Example 1, 3-(o-hydroxyphenyl)propionate menthyl ester, 5-hydroxyhexanoate geraniol ester, and 3-(2-hydroxycyclohexyl)propionate phenylethyl alcohol ester were synthesized.

[0070] Dissolve menthyl 3-(o-hydroxyphenyl)propionate, geraniol 5-hydroxyhexanoate, and phenylethyl 3-(2-hydroxycyclohexyl)propionate in a molar ratio of 1:3:1 in (mass ratio is 10 / 90) mixed solvent to prepare a solution with a mass percentage of 0.3%.

[0071] Tobacco raw materials (50% stalk material, 40% leaf material, 10% wood pulp) are mixed and soaked in water for extraction. After the soluble part in the extract is concentrated, the aforementioned three kinds of ethanol / water solutions of 5-hydroxyacid alcohol esters are dispersed in the concentrated extract in the batching tank (mass ratio is 1 / 100). The solid matter separated from the extractor is made into a fourdrinier paper machine to obtain a tobacco substrate, and the extract is dip-coated on the sub...

Embodiment 3

[0075] Mix 31.25g of menthol, 11.41g of δ-caprolactone, 14.82g of dihydrocoumarin and 0.4g of citric acid in a 100mL single-necked bottle, and heat at 70°C for 5 hours to obtain menthol containing 5-hydroxycaproate Alcohol esters and 3-(2-hydroxyphenyl) menthyl propionate mixed latent substances (this case is also collectively referred to as delta-hydroxy acid menthyl esters).

[0076] Using a method similar to that of Example 1, tobacco sheets were prepared. And carry out the evaluation test on it.

Abstract

The invention belongs to the technical field of cigarette perfuming, and particularly provides a tobacco sheet containing 5-hydroxy acid alcohol ester as well as a preparation method and application of the tobacco sheet. Preferred tobacco sheets of the present invention comprise a tobacco substrate and a coating layer comprising a 5-hydroxy acid alcohol ester. The tobacco sheet prepared by the invention can effectively provide composite aroma of alcohol spice and another delta-lactone during combustion, and the smoking quality of cigarettes can be improved.

Description

technical field [0001] The invention belongs to the technical fields of tobacco sheet technology and essence and fragrance, and in particular relates to a preparation method of tobacco sheet containing 5-hydroxy acid alcohol ester. Background technique [0002] Tobacco sheet is mainly composed of tobacco powder, tobacco stem, and tobacco leaf fragments. The manufacture and application of tobacco sheet has a very significant effect on improving the utilization rate of tobacco leaf raw materials, reducing the tar content in cigarettes, and improving and enhancing the quality of cigarette products. [0003] Tobacco flakes will lose part of the endogenous flavors of tobacco during the processing process, and there will be insufficient aroma substances during burning and smoking, and there will be problems such as woody and spicy odors. Tobacco flakes can be improved by adding a certain amount of tobacco extract or exogenous flavors. combustion quality. Flavors with lower boilin...
