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-Thr, which comprises the steps of:

[0029] Add 1 gram of maltose, 1.5 mL of dimethylformamide, and 3.0 mL of anhydrous methanol into a three-necked flask equipped with a thermometer and a condenser tube, reflux at 75°C for 20 minutes, then add 0.132 grams of threonine and reflux for another 20 minutes, and finally 0.032 g of strong acidic ion exchange resin and 0.326 g of myricetin were added for reflux reaction for 1 h; after the reaction, 0.293 g of the target product in the form of white crystals was obtained by silica gel column chromatography and recrystallization. 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 5:2:1, and the color developer is ninhydrin ethanol solution; the solvent used for recrystallization It is a mixed solution of absolute ethanol and absolute methanol with a volume rat...

Embodiment 2

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

[0032] Add 1 gram of maltose, 3.4 mL of dimethylformamide, and 2.1 mL of anhydrous methanol into a three-necked flask equipped with a thermometer and a condenser tube, reflux at 82°C for 36 minutes, then add 0.266 grams of threonine and reflux for another 36 minutes, and finally Add 0.056 g of strong acidic ion-exchange resin and 1.015 g of myricetin for reflux reaction for 3.5 h; after the reaction, separate by silica gel column chromatography and recrystallize to obtain 0.867 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-Thr, which comprises the steps of:

[0035] Add 1 gram of maltose, 3.8 mL of propylene glycol and 1.6 mL of anhydrous methanol into a three-necked flask with a thermometer and a condenser, reflux at 89°C for 50 minutes, then add 0.331 grams of threonine and reflux for another 50 minutes, and finally add 0.062 grams of strong The acidic ion exchange resin and 1.619 g of myricetin were refluxed for 8.5 hours; after the reaction, separated by silica gel column chromatography and recrystallized to obtain 0.535 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-Thr used for cigarettes as well as a preparation method and application thereof. A structure of Mal-Thr is shown in the specification. Through physical humectant property tests of cigarettes and inner sensory quality evaluation of finished cigarettes, the monomer flavor is found to be capable of obviously improving the physical humectant properties of cut tobaccos, also have the function of obviously improving the sensory quality of the cigarettes and be capable of reducing the irritation and offensive odors of the cigarettes and improving 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-Thr 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...
