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 preparation method of hydrophilic type tobacco flavoring moisturizing agent Mal-Ala, 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-neck flask equipped with a thermometer and a condenser, and reflux at 70°C for 15 minutes; then add 0.099 gram of alanine and reflux for another 15 minutes, and finally Add 0.03 g of strongly acidic ion-exchange resin and 0.159 g of kaempferol for reflux reaction for 1 h. After the reaction was completed, 0.343 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 4:2:1, and the chromogenic agent is ninhydrin ethanol solution; the solvent used for recrystallization It is a mixed solution of absolute ethanol ...

Embodiment 2

[0031] A kind of preparation method of hydrophilic type tobacco flavoring moisturizing agent Mal-Ala, 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-necked flask equipped with a thermometer and a condenser, and reflux at 83°C for 26 minutes; then add 0.132 grams of alanine and reflux for another 26 minutes, and finally Add 0.04 g of strongly acidic ion exchange resin and 0.637 g of kaempferol to reflux for 4.5 h. After the reaction was completed, 0.773 g of the target product in the form of white crystals was obtained by silica gel column chromatography and recrystallization. Wherein, the operation process of column chromatography separation and recrystallization is the same as that of Example 1.

Embodiment 3

[0034] A kind of preparation method of hydrophilic type tobacco flavoring moisturizing agent Mal-Ala, 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 tube, reflux at 90°C for 40 minutes, then add 0.247 grams of alanine and reflux for another 40 minutes, and finally add 0.06 grams of strong Acidic ion exchange resin and 0.794 g of kaempferol were refluxed for 6 hours. After the reaction was completed, 0.618 g of the target product in the form of white crystals was obtained by silica gel column chromatography and recrystallization. Wherein, the operation process of column chromatography separation and recrystallization is the same as that of Example 1.

Abstract

The invention belongs to the technical field of humectants used for tobaccos and in particular relates to a novel hydrophilic tobacco aroma enhancing humectant Mal-Ala as well as a preparation method and application thereof. A structural formula of Mal-Ala 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 technical field of humectants for tobacco, and in particular relates to a novel hydrophilic tobacco aroma-enhancing moisturizer Mal-Ala, 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...
