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 sugar derivative cigarette flavoring humectant Mal-Trp, it comprises the steps:

[0029] Add 1 gram of maltose, 0.7 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 73°C for 15 minutes, then add 0.227 grams of tryptophan and reflux for another 15 minutes, and finally Add 0.026 g of strong acidic ion exchange resin and 0.018 g of myricetin for reflux reaction for 1.5 h; after the reaction, separate by silica gel column chromatography and recrystallize to obtain 0.503 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 m...

Embodiment 2

[0031] A kind of preparation method of sugar derivative cigarette flavoring humectant Mal-Trp, it comprises the steps:

[0032] Add 1 gram of maltose, 1.0 mL of dimethylformamide, and 1.5 mL of anhydrous methanol into a three-necked flask with a thermometer and a condenser tube, reflux at 80°C for 30 minutes, then add 0.432 grams of tryptophan and reflux for another 30 minutes, and finally 0.036 g of strong acidic ion exchange resin and 0.068 g of myricetin were added for reflux reaction for 3.5 hours; after the reaction, 1.076 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 kind of preparation method of sugar derivative cigarette flavoring humectant Mal-Trp, it comprises the 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 45 minutes, then add 0.567 grams of tryptophan and reflux for another 40 minutes, and finally add 0.056 grams of strong The acidic ion exchange resin and 0.088 g of myricetin were refluxed for 7.5 hours; after the reaction, 0.777 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 used for tobaccos and in particular relates to a sugar derived aroma enhancing humectant Mal-Trp used for tobaccos as well as a preparation method and application thereof. A structural formula of Mal-Trp 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 cigarettes, and in particular relates to Mal-Trp, a flavoring and humectant for cigarettes derived from sugar, 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 ci...
