Problems solved by technology

At present, the humectants widely used in cigarettes in my country mainly include propylene glycol and sorbitol. The purpose of using such humectants is to increase the moisture content of shredded tobacco during processing and improve the processing resistance of shredded tobacco. The maintenance of moisture content in shredded tobacco and the improvement of sensory comfort in cigarettes are not ideal

Embodiment 1

[0028] A preparation method for tobacco monomer spice Mal-Va, which comprises the steps of:

[0029] Add 1 gram of maltose, 1.3 mL of dimethylformamide, and 3.3 mL of anhydrous methanol into a three-necked flask with a thermometer and a condenser tube, reflux at 73°C for 20 minutes, then add 0.130 gram of valine and reflux for another 20 minutes, and finally Add 0.035 g of strong acidic ion exchange resin and 0.168 g of quercetin for reflux reaction for 1 h; after the reaction, separate and recrystallize through silica gel column chromatography to obtain 0.371 g of the target product in the form of white crystals. Among them, the eluent used for column chromatography separation is a mixed solution composed of n-butanol, glacial acetic acid and water, the volume ratio of the three is 4:1:1, and the chromogenic agent is ninhydrin ethanol solution; the solvent used for recrystallization It is a mixed solution of absolute ethanol and absolute methanol with a volume ratio of 1:1. ...

Embodiment 2

[0031] A preparation method for tobacco monomer spice Mal-Va, which comprises the steps of:

[0032] Add 1 gram of maltose, 3.2 mL of dimethylformamide, and 2.0 mL of anhydrous methanol into a three-necked flask with a thermometer and a condenser tube, reflux at 81°C for 28 minutes, then add 0.286 grams of valine and reflux for another 28 minutes, and finally Add 0.05 g of strong acidic ion-exchange resin and 0.662 g of quercetin for reflux reaction for 4 h; after the reaction, separate by silica gel column chromatography and recrystallize to obtain 0.848 g of the target product in the form of white crystals. Wherein, the operation process of column chromatography separation and recrystallization is the same as that of Example 1.

Embodiment 3

[0034] A preparation method for tobacco monomer spice Mal-Va, which comprises the steps of:

[0035] Add 1 gram of maltose, 3.6 mL of propylene glycol and 1.8 mL of anhydrous methanol into a three-necked flask with a thermometer and a condenser tube, reflux at 88°C for 40 minutes, then add 0.325 grams of valine and reflux for another 40 minutes, and finally add 0.067 grams of strong Acidic ion-exchange resin and 0.838 g of quercetin were refluxed for 7 hours; after the reaction, separated by silica gel column chromatography and recrystallized to obtain 0.597 g of the target product in the form of white crystals. Wherein, the operation process of column chromatography separation and recrystallization is the same as that of Example 1.

Abstract

The invention relates to a novel monomer flavor Mal-Val used for cigarettes as well as a preparation method and application thereof. A structure of Mal-Val is shown in the specification. Through physical humectant property tests and inner sensory quality evaluation of the monomer flavor, the monomer flavor is found to have the function of obviously improving the physical humectant properties of cut tobaccos, also have the function of obviously improving the sensory quality of the cigarettes, reduce the irritation and the offensive odor, and improve the mellowness and fullness of the cigarette smoke.

Description

technical field [0001] The invention belongs to the field of flavors and fragrances and tobacco processing, and in particular relates to a novel monomer fragrance Mal-Val for cigarettes, a preparation method and an application thereof. Background technique [0002] As people pay more and more attention to smoking and health problems, while the tar content of cigarettes is further reduced, the comfort of cigarettes becomes worse, which is mainly reflected in the loss of water dispersion of shredded tobacco, low moisture in mainstream smoke, high irritation, and dry mouth. And phlegm etc. At present, the humectants widely used in cigarettes in my country mainly include propylene glycol and sorbitol. The purpose of using such humectants is to increase the moisture content of shredded tobacco during processing and improve the processing resistance of shredded tobacco. The maintenance of moisture content of shredded tobacco and the improvement of sensory comfort of cigarettes a...
