Embodiment 1

[0036] A kind of flavoring for tobacco is prepared, and the steps are as follows:

[0037] Accurately measure 9.9 g of diammonium hydrogen phosphate, dissolve it in distilled water to prepare an aqueous solution with a mass concentration of 9%, take 100 g of the solution, and adjust its pH value to 7.0-8.0 with sodium hydroxide.

[0038] To the resulting solution was added 13.2 g of 3-hydroxy-2-butanone and mixed well by stirring.

[0039] The uniformly mixed reaction solution was transferred to the reaction kettle, the heating device was turned on and the temperature was raised to 70° C., and the reaction was carried out under normal pressure for 12 hours, and then the temperature was lowered to room temperature, and the reaction was completed.

[0040] Dilute the reaction solution 5 times with distilled water, extract 3 times with dichloromethane, 300 mL each time, combine the organic phases, remove water with sodium sulfate, and then concentrate under reduced pressure. , a...

Embodiment 2

[0042] A kind of flavoring for tobacco is prepared, and the steps are as follows:

[0043] Measure 16.9 g of ammonium citrate, dissolve it in distilled water to prepare an ammonium citrate aqueous solution with a mass concentration of 14%, take 100 g of the solution, and adjust its pH value to 7.0-8.0 with sodium hydroxide.

[0044] To the resulting solution was added 13.2 g of 3-hydroxy-2-butanone, and the reaction solution was well mixed by stirring.

[0045] The uniformly mixed reaction solution was transferred to the reaction kettle, the heating device was turned on and the temperature was raised to 70° C., and the reaction was carried out under normal pressure for 12 hours, and then the temperature was lowered to room temperature, and the reaction was completed.

[0046] The resulting reaction solution was diluted 5 times with distilled water, extracted 3 times with dichloromethane, 300 mL each time, and the organic phase was combined to remove water with sodium sulfate, ...

Embodiment 3

[0048] Prepare a flavor for tobacco, the steps are as follows:

[0049] Measure 5 g of diammonium hydrogen phosphate and 8 g of ammonium citrate respectively, dissolve them in distilled water to prepare an aqueous solution with a mass concentration of 14%, take 100 g of the solution, and adjust its pH value to about 8.0 with sodium hydroxide.

[0050] To the obtained solution was added 12.9 g of 3-hydroxy-2-butanone, and the reaction solution was well mixed by stirring.

[0051] The uniformly mixed reaction solution was transferred to the reaction kettle, the heating device was turned on and the temperature was raised to 70° C., and the reaction was carried out under normal pressure for 12 hours, and then cooled to room temperature, and the reaction was completed.

[0052] The resulting reaction solution was diluted 5 times with distilled water, and then extracted 3 times with dichloromethane, 300 mL each time. After combining the organic phases, the water was removed with sodiu...

Abstract

The invention relates to a method for preparing a tobacco flavour. The method mainly comprises the following steps of: preparing ammonia precursor solution, adding a carbonyl compound, uniformly mixing, heating and reacting, and extracting and separating to obtain the tobacco flavour. The tobacco flavour has evident effect on the aroma modification and tobacco taste improvement in the middle-highgrade tobacco leaf group formula; and for the low-grade tobacco leaves, tobacco stems or tobacco sheets, the tobacco flavour has the effects of evidently increasing the tobacco aroma, reducing the irritation, piquancy feel and throat dry sensation, improving the tobacco taste, reducing the residuals in the oral cavity and the like.

Description

【Technical field】 [0001] The invention relates to the technical field of flavoring essence for tobacco. More specifically, the present invention relates to a flavoring for tobacco, and also relates to a preparation method and application of the flavoring for tobacco. 【Background technique】 [0002] Low-grade tobacco leaves, thin slices and cut stems are important raw materials in cigarette products, but these raw materials have congenital defects, including lack of characteristic cigarette aroma or light tobacco aroma, heavy miscellaneous and woody smell, dry throat and tongue The pungent feeling is obvious on the inside, so the introduction of these raw materials into the leaf group formula will significantly reduce the grade of cigarettes. Improving the aroma of low-grade tobacco leaves, thin slices and cut stems, and solving the negative effects on the senses will have a profound impact on improving the overall smoking quality of cigarettes. One of the most important me...
