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 of sugar derivative tobacco flavoring and moisturizing agent Mal-Pro, which comprises the following steps:

[0029] Add 1 gram of maltose, 0.7 mL of dimethylformamide, and 1.5 mL of anhydrous methanol into a three-neck flask equipped with a thermometer and a condenser tube, reflux at 73°C for 10 minutes, then add 0.128 grams of proline and reflux for 10 minutes again, and finally Add 0.02 g of strong acidic ion exchange resin and 0.018 g of myricetin for reflux reaction for 2 h. After the reaction was completed, 0.457 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 et...

Embodiment 2

[0031] A preparation method of sugar derivative tobacco flavoring and moisturizing agent Mal-Pro, which comprises the following steps:

[0032] Add 1 gram of maltose, 1.0 mL of dimethylformamide, and 1.5 mL of anhydrous methanol into a three-necked flask equipped with a thermometer and a condenser, and reflux at 80°C for 20 minutes, then add 0.32 grams of proline and reflux for another 20 minutes, and finally Add 0.03 g of strong acidic ion exchange resin and 0.068 g of myricetin for reflux reaction for 4 h. After the reaction was completed, 0.857 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 preparation method of sugar derivative tobacco flavoring and moisturizing agent Mal-Pro, which comprises the following steps:

[0035] Add 1 gram of maltose, 1.5 mL of propylene glycol and 1.0 mL of anhydrous methanol into a three-necked flask with a thermometer and a condenser tube, reflux at 89°C for 40 minutes, then add 0.25 grams of proline and reflux for another 20 minutes, and finally add 0.05 grams of strong Acidic ion exchange resin and 0.088 g of myricetin were refluxed for 8 h to react. After the reaction was completed, 0.632 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 field of humectants for cigarettes, and particularly relates to a saccharide-derived flavor-enhancing humectant Mal-Pro for cigarettes, and a preparation method and application thereof. The structural formula of the Mal-Pro is disclosed in the specification. The physical humidification performance testing and inherent esthetic quality evaluation on the compound detect that the compound has the function of obviously enhancing the physical humidification performance of the tobacco shred, has obviously improvement function on the esthetic quality of cigarettes, lowers the irritation and impurity gas and enhances the smoothness of the cigarette smoke.

Description

[0001] technical field [0002] The invention belongs to the field of moisturizing agents for cigarettes, and in particular relates to Mal-Pro, a sugar derivative tobacco flavoring and moisturizing agent, a preparation method and an application thereof. [0003] Background technique [0004] 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 sensor...
