Problems solved by technology

[0006] The purpose of the present invention is to solve the problem that the traditional spices in low-temperature cigarettes are easy to volatilize during processing and storage, and under heating conditions, the spices volatilize quickly, the aroma will be lost quickly, the aroma is not long-lasting, and the aroma is uneven during the smoking process. Provides a new type of tobacco flavor, the solid acid in the tobacco flavor can catalyze the cracking of glycosides at a lower temperature, release aroma stably and persistently, and increase the aroma of cigarettes, so it is more suitable as a flavor substance for low-temperature cigarettes

preparation example Construction

[0030] In the preparation method provided by the present invention, the contact of the solid acid and the glycoside can be carried out in any way, for example, mixing in a solid phase, a liquid phase or a combination thereof. In a preferred embodiment of the present invention, the contacting may be performed by grinding and mixing the solid acid and the solid glycoside; and / or may be performed by soaking the solid acid in the glycoside solution.

[0031] When the contacting is performed by grinding and mixing the solid acid and the solid glycoside as described above, the mixing ratio of the solid acid and the solid glycoside may be 1:5-1:1000 (weight ratio). When the contacting is carried out by dipping the solid acid in a glycoside solution as described above, the glycoside solution may be a solution of glycoside in water, ethanol, propylene glycol, glycerol, or combined, and the contacting may further include baking or drying at a low temperature after the solid acid is soak...

Embodiment 1

[0038] In geraniol glucoside, add the solid acid of 5% (weight ratio) (the chemical composition of the solid acid used in the embodiment is expressed as with the mol ratio of oxide compound: aNa 2 O:bAl 2 o 3 : cSiO 2 , where a<0.1%, b / c=1 / 25), and mix well.

[0039] The resulting mixture and pure geraniol glucoside were put into CDS 5250T pyrolysis apparatus for cracking and analysis respectively. The sample cell used in the cracking test is a stainless steel high-pressure crucible with a gold-plated gasket, with a capacity of 30 μL and a maximum pressure resistance of 15 MPa. The reference crucibles are all high-pressure stainless steel crucibles of the same material. The heating rate (β) of the dynamic DSC test is 10°C / min, the test temperature range is 30-800°C, and the sample mass (m) is 3.5±0.05mg. Comparative analysis figure 1 with figure 2 (the DSC-TG-DTG collection of illustrative plates of pure geraniol glucoside and geraniol glucoside+5% solid acid according ...

Embodiment 2

[0042] Add 10% (by weight) solid acid (same as Example 1) to the menthol glucoside, and mix well.

[0043] The resulting mixture and pure menthol glucoside were put into CDS 5250T pyrolysis apparatus for cracking and analysis respectively. Cracking condition is identical with embodiment 1. The weight loss peaks of pure menthol glucoside DTG curves were at 243°C and 315°C, respectively, while the DTG weight loss peaks decreased to 204°C and 228°C after adding solid acid. This shows that the solid acid greatly reduces the thermal cracking temperature of menthol glucoside.

[0044] The mixture solid of menthol glucoside + 10% (weight ratio) solid acid and tobacco powder are evenly mixed according to the weight ratio of 1:2000 to prepare tobacco flakes, and the tobacco flakes and cooling nozzle rods are connected through tipping paper to form Low-temperature cigarettes; in addition, menthol glucoside solids and tobacco powder were uniformly mixed according to a weight ratio of 0...

Abstract

The invention provides a tobacco flavor and a preparation method thereof, the tobacco flavor comprises solid acid and glucoside, and the weight ratio of the solid acid to the glucoside is 1: 5-1: 1000. Furthermore, the invention also provides application of the tobacco flavor as a flavor substance in low-temperature cigarettes. In the tobacco flavor, the solid acid is used as a catalyst, so that the thermal decomposition temperature of glycoside substances can be obviously reduced, the tobacco flavor is particularly suitable for low-temperature cigarettes, the flavor substances are not volatilized or lost in a normal-temperature state, and even if the low-temperature cigarettes are stored for a long time, the aroma is still lasting and stable during smoking.

Description

technical field [0001] The invention belongs to the field of heated cigarette flavorings, and more specifically relates to a flavoring for tobacco and a preparation method thereof. The solid acid (catalyst) in the flavoring for tobacco can catalyze and reduce the cracking temperature of glycoside flavorings, at a lower temperature The aroma is released by thermal cracking, so the tobacco flavor is especially suitable for low-temperature cigarettes. Background technique [0002] Tobacco (flavor) flavors in cigarettes have the functions of enriching the aroma of cigarettes, improving the quality of smoking, highlighting and forming the style of cigarettes, and are one of the core technologies of cigarettes. For traditional cigarettes, it is most common to apply flavors and fragrances to shredded tobacco. During the smoking process, the flavor components enter the consumer's mouth through volatilization, distillation, pyrolysis, cracking, etc. to enhance the smoking experience....
