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 for tobacco monomer spice Mal-Phe, comprising the steps of:

[0029] Add 1 gram of maltose, 1.3 mL of dimethylformamide, and 3.0 mL of anhydrous methanol into a three-necked flask equipped with a thermometer and a condenser, reflux at 70°C for 23 minutes, then add 0.183 grams of phenylalanine and reflux for another 23 minutes. Finally, 0.032 g of strong acidic ion exchange resin and 0.176 g of myricetin were added for reflux reaction for 1 h; after the reaction, 0.339 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 6:2:1, and the chromogenic agent is ninhydrin ethanol solution; the solvent used for recrystallization It is a mixed solution of absolute ethanol and absolute methanol with a volume ratio of 1...

Embodiment 2

[0031] A preparation method for tobacco monomer spice Mal-Phe, comprising the steps of:

[0032] Add 1 gram of maltose, 3.3 mL of dimethylformamide, and 1.9 mL of anhydrous methanol into a three-necked flask equipped with a thermometer and a condenser, reflux at 83°C for 29 minutes, then add 0.386 grams of phenylalanine and reflux for another 29 minutes. Finally, 0.049 g of strong acidic ion exchange resin and 0.562 g of myricetin were added for reflux reaction for 3.7 h; after the reaction, 0.97 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 for tobacco monomer spice Mal-Phe, comprising the steps of:

[0035] Add 1 gram of maltose, 3.6 mL of propylene glycol and 1.8 mL of anhydrous methanol into a three-necked flask with a thermometer and a condenser, reflux at 88°C for 46 minutes, then add 0.458 grams of phenylalanine and reflux for another 46 minutes, and finally add 0.061 grams of Strongly acidic ion exchange resin and 0.891 g of myricetin were refluxed for 7.5 hours; after the reaction, separated by silica gel column chromatography and recrystallized to obtain 0.671 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 relates to a novel monomer spice Mal-Phe for tobacco as well as a preparation method and application thereof. The structural formula of the Mal-Phe is shown in the specification. By performing physical moist keeping performance tests and inner sensory quality evaluation on the monomer spice, the novel monomer spice Mal-Phe has the effect of obviously improving the physical moist keeping performance of the tobacco, meanwhile the sensory quality of the tobacco is obviously improved, the irritation and offensive odor are reduced, and the mellow and full feeling of the smoke the tobacco is promoted.

Description

technical field [0001] The invention belongs to the field of flavors and fragrances and tobacco processing, and in particular relates to a novel monomer fragrance Mal-Phe for cigarettes, 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 a...
