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

[0026] A preparation method for tobacco monomer spice Mal-Va, which comprises the steps of:

[0027] Add 1 gram of maltose, 1.3 mL of dimethylformamide, and 3.3 mL of anhydrous methanol into a three-necked flask with a thermometer and a condenser tube, reflux at 73°C for 20 minutes, then add 0.130 gram of valine and reflux for another 20 minutes, and finally Add 0.035 g of strong acidic ion-exchange resin and 0.168 g of quercetin for reflux reaction for 1 h; after the reaction, separate and recrystallize through silica gel column chromatography to obtain 0.371 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 4:1:1, 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 1:1. ...

Embodiment 2

[0029] A preparation method for tobacco monomer spice Mal-Va, which comprises the steps of:

[0030] Add 1 gram of maltose, 3.2 mL of dimethylformamide, and 2.0 mL of anhydrous methanol into a three-necked flask with a thermometer and a condenser tube, reflux at 81°C for 28 minutes, then add 0.286 grams of valine and reflux for another 28 minutes, and finally 0.05 g of strong acidic ion exchange resin and 0.662 g of quercetin were added for reflux reaction for 4 h; after the reaction, 0.848 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

[0032] A preparation method for tobacco monomer spice Mal-Va, which comprises the steps of:

[0033] 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 tube, reflux at 88°C for 40 minutes, then add 0.325 grams of valine and reflux for another 40 minutes, and finally add 0.067 grams of strong Acidic ion exchange resin and 0.838 g of quercetin were refluxed for 7 hours; after the reaction, separated by silica gel column chromatography and recrystallized to obtain 0.597 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-Val for cigarettes, a preparation method and an application thereof. The Mal-Val structure is as follows:. The present invention conducts the physical moisturizing performance test and internal sensory quality evaluation of the monomer fragrance, and finds that it can significantly improve the physical moisturizing performance of shredded tobacco, and at the same time significantly improve the sensory quality of cigarettes, reduce irritation and miscellaneous gas, and improve It enhances the mellowness of cigarette smoke.

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-Val 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 are...
