Technical Field

The invention belongs to the field of heating cigarette flavors, and particularly relates to a cigarette flavor and a preparation method thereof.

Background

The (essence) spice for the cigarette has the functions of enriching the cigarette fragrance, improving the smoking quality, highlighting and forming the cigarette style in the cigarette, and is one of the core technologies of the cigarette. For traditional cigarettes, the most common is to apply the essence and the spice to the cut tobacco of the cigarettes, and in the smoking process of a consumer, the flavor components enter the oral cavity of the consumer through volatilization, distillation, pyrolysis, cracking and the like, so that the smoking feeling is improved. The low-temperature cigarette, also called a heat-not-burn cigarette (heat-not-burn cigarette), heats the tobacco substance by an external heat source, and the atomized medium, the flavor components and the additional flavor in the tobacco substance generate smoke similar to the smoke of the traditional cigarette smoking by heating, so that the consumers can obtain physiological satisfaction. As the tobacco substances in the low-temperature cigarette are only heated but not burnt, the heating temperature (200-.

Glycosides are precursor substances for many fragrance ingredients, which are converted by thermal effects and catalytic cracking to form one or more aroma components, which have a great potential for releasing aroma. The glucoside serving as the perfume precursor well overcomes the defect that the fragrance of the traditional perfume volatilizes quickly and is not persistent, and can stably and persistently release the fragrance.

The thermal decomposition temperature of the glucoside is 250-400 ℃ or even higher, and for the traditional cigarette, the glucoside can be better thermally decomposed to release aroma due to higher combustion temperature (800-900 ℃); for low-temperature cigarettes, the heating temperature (200-.

Therefore, the method has the advantages that the thermal decomposition temperature of the glucoside is reduced, the glucoside is more fully thermally decomposed to release fragrance, and the glucoside plays a better role in low-temperature cigarettes.

5% by weight of solid acid (the chemical composition of the solid acid used in the examples is expressed as the molar ratio of the oxide: aNa) was added to the geraniol glucoside₂O:bAl₂O₃:cSiO₂In the formula a<0.1%, b/c 1/25) and mixed well.

The resulting mixture and pure geraniol glucoside were separately subjected to cleavage and analysis in a CDS 5250T pyrolysis instrument. The sample cells used in the cracking test are all stainless steel high-pressure crucibles with gold-plated gaskets, the capacity is 30 mu L, the highest pressure resistance is 15MPa, and the reference crucibles are all high-pressure stainless steel crucibles made of the same material. The temperature rise rate (beta) of the dynamic DSC test is 10 ℃/min respectively, the test temperature range is 30-800 ℃, and the sample mass (m) is 3.5 +/-0.05 mg. Comparative analysis of fig. 1 and 2 (DSC-TG-DTG spectra of pure geraniol glucoside and geraniol glucoside + 5% solid acid according to the invention, respectively) it can be seen that the pure geraniol glucoside DTG curve has weight loss peaks at 239 ℃ and 333 ℃, respectively, whereas the DTG weight loss peaks decrease to 219 ℃ and 260 ℃ after addition of solid acid. This indicates that the solid acid greatly reduced the thermal cracking temperature of geraniol glucoside.

The result of smoke panel test shows that the low-temperature cigarette has the advantages of being fragrant, obvious in roasted sweet aroma, obvious and full in aroma, elegant in fragrance and strong in smoking satisfaction.

Example 2

To menthol glucoside was added 10% by weight of a solid acid (same as in example 1) and mixed well.

The resulting mixture and pure menthol glucoside were separately subjected to cleavage and analysis in a CDS 5250T pyrolysis apparatus. The cleavage conditions were the same as in example 1. The weight loss peak values of the DTG curve of the pure menthol glucose glycoside are respectively 243 ℃ and 315 ℃, and the weight loss peak values of the DTG are reduced to 204 ℃ and 228 ℃ after the solid acid is added. This indicates that the solid acid greatly reduced the thermal cracking temperature of the menthol glucoside.

Example 3

To ethyl vanillin glucoside was added 2% by weight of a solid acid (same as in example 1) and mixed well.

The resulting mixture and pure ethyl vanillin glucoside were separately subjected to cleavage and analysis in a CDS 5250T pyrolysis apparatus. The cleavage conditions were the same as in example 1. The weight loss peak values of the DTG curve of the pure ethyl vanillin glucose glucoside are respectively 242 ℃ and 326 ℃, and the weight loss peak values of the DTG are reduced to 231 ℃ and 278 ℃ after the solid acid is added. This indicates that the solid acid greatly reduced the thermal cracking temperature of the ethyl vanillin glucoside.
