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 kind of hydrophilic tobacco flavoring humectant Mal-Gly, it comprises the steps:

[0029] Add 1 gram of maltose, 1.4 mL of dimethylformamide, and 3.0 mL of anhydrous methanol into a three-necked flask equipped with a thermometer and a condenser, and reflux at 70°C for 13 minutes; then add 0.083 grams of glycine and reflux for another 13 minutes, and finally add 0.03 One gram of strong acidic ion exchange resin and 0.139 gram of kaempferol were refluxed for 1 hour. After the reaction, the product was separated by silica gel column chromatography and recrystallized to obtain 0.322 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 4:2:1, and the chromogenic agent is ninhydrin ethanol solution; the solvent used for recrystallization It is a mixed solution of absolute ethanol and absolute methanol ...

Embodiment 2

[0031] A kind of hydrophilic tobacco flavoring humectant Mal-Gly, it comprises the steps:

[0032] Add 1 gram of maltose, 2.0 mL of dimethylformamide, and 2.0 mL of anhydrous methanol into a three-neck flask equipped with a thermometer and a condenser, and reflux at 83°C for 35 minutes; then add 0.198 grams of glycine and reflux for another 35 minutes, and finally add 0.04 Gram of strong acidic ion exchange resin and 0.612 g of kaempferol were refluxed for 4 hours. After the reaction, the product was separated by silica gel column chromatography and recrystallized to obtain 0.804 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 kind of hydrophilic tobacco flavoring humectant Mal-Gly, it comprises the steps:

[0035] Add 1 gram of maltose, 3.0 mL of propylene glycol and 2.0 mL of anhydrous methanol into a three-necked flask with a thermometer and a condenser, reflux at 90°C for 49 minutes, then add 0.208 grams of glycine and reflux for another 49 minutes, and finally add 0.06 grams of strong acidic ions The exchange resin and 0.768 g of kaempferol were refluxed for 6 h to react. After the reaction, the product was separated by silica gel column chromatography and recrystallized to obtain 0.536 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 belongs to the field of humectants for tobaccos and in particular relates to a novel hydrophilic tobacco aroma enhancing humectant Mal-Gly as well as a preparation method and application thereof. A structural formula of Mal-Gly is shown in the specification. Through physical humectant property tests and inner sensory quality evaluation of the compound, the compound 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 tobacco humectants, and in particular relates to a novel hydrophilic tobacco flavoring humectant Mal-Gly, 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 are not ideal. Cont...
