Problems solved by technology

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

Embodiment 1

[0028] A preparation method of hydrophilic tobacco flavoring and moisturizing agent Mal-Hyp, which comprises the steps of:

[0029] Add 1 gram of maltose, 1.3 mL of dimethylformamide and 2.9 mL of anhydrous methanol into a three-necked flask equipped with a thermometer and a condenser, reflux at 73°C for 16 minutes, then add 0.146 grams of hydroxyproline and reflux for another 16 minutes. Finally, 0.028 grams of strong acidic ion exchange resin and 0.160 grams of kaempferol were added for reflux reaction for 1.6 hours. After the reaction, 0.344 grams of the target product Mal-Hyp in the form of white crystals was obtained through silica gel column chromatography separation and recrystallization; The eluent used is a mixed solution 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 is a volume ratio of 1: 1 mixed solution of absolute ethanol and abso...

Embodiment 2

[0031] A preparation method of hydrophilic tobacco flavoring and moisturizing agent Mal-Hyp, which comprises the steps of:

[0032] Add 1 gram of maltose, 3.7 mL of dimethylformamide, and 2.0 mL of anhydrous methanol into a three-neck flask equipped with a thermometer and a condenser tube, reflux at 86°C for 30 minutes, then add 0.352 grams of hydroxyproline and reflux for another 30 minutes. Finally, 0.05 g of strong acidic ion exchange resin and 0.063 g of kaempferol were added for reflux reaction for 5 hours. After the reaction, 0.872 g of the target product in the form of white crystals was obtained through 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 hydrophilic tobacco flavoring and moisturizing agent Mal-Hyp, which comprises the steps of:

[0035] Add 1 gram of maltose, 4.0 mL of propylene glycol and 1.6 mL of anhydrous methanol into a three-necked flask with a thermometer and a condenser tube, reflux at 90°C for 45 minutes, then add 0.364 grams of hydroxyproline and reflux for another 45 minutes, and finally add 0.066 grams of The strongly acidic ion exchange resin and 0.802 g of kaempferol were refluxed for 9 hours. After the reaction, 0.616 g of the target product in the form of white crystals was obtained through 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 for tobacco and particularly relates to a hydrophilic aroma-enhancing humectant Mal-Hyp for tobacco, a preparation method and an application of the humectant. The structural formula of the Mal-Hyp is shown in a formula in the specification. According to the invention, physical humidifying performance test and interior sensory quality of the compound are evaluated, discovering that the humectant plays a role of remarkably improving the physical humidifying performance of cut tobacco and meanwhile has a remarkable improving effect to sensory quality of tobacco, so that the irritation and miscellaneous odors are reduced and the mellow and full sense of the smoke of cigarettes is enhanced.

Description

technical field [0001] The invention belongs to the technical field of humectants for tobacco, and in particular relates to a novel hydrophilic tobacco flavoring humectant Mal-Hyp, a preparation method and an application thereof. Background technique [0002] As people pay more and more attention to smoking and health problems, while further reducing the amount of tar in cigarettes, the comfort of cigarettes becomes worse, which is mainly reflected in the loss of water dispersion in 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, sorbitol, etc. The use of such humectants can improve the moisture content of shredded tobacco during processing and the processing resistance of shredded tobacco. The maintenance of moisture content and the improvement of sensory comfort are not ideal. Contents of the invention [0003] The purp...
