Preparation method of jujube subcritical extract and application of jujube subcritical extract in cigarette

Abstract

The invention relates to a preparation method of a jujube subcritical extract and an application of the jujube subcritical extract in a cigarette. The method comprises the following steps: a, drying the preprocessed jujube at the temperature of 50 to 80 DEG C, and then pulverizing the dried jujube until the granularity is 10-100 meshes; b, subcritically extracting the jujube powder obtained in the step a for 0.1-2 hours by utilizing the subcritical extracting agent under the condition that the temperature is 0-50 DEG C and the extracting pressure is 0.5-3Mpa, and separating the extract liquid by use of the decompression evaporation principle to obtain the jujube subcritical extract, wherein an ethanol solution is used as a carrier agent, the concentration is 50 to 95 percent, and the consumption of the ethanol solution is 1 to 5 times that of the jujube powder. The jujube subcritical extract is used as cigarette liquid so as to be added into a cigarette tobacco shred, the exclusive chemical component can be generated when the cigarette is burned, so that the quality of the cigarette can be obviously improved. Under the situation that the original performance of the cigarette is not changed, the smoking quality of the cigarette is improved, and the real production significance and value are better.

Description

technical field

[0001] The invention relates to plant extraction and its application, in particular to the preparation method of the jujube extract and its application in cigarettes. The application of this technology does not change the existing processing technology of the cigarette, and can improve the sensory quality of the cigarette.

[0002] Background technique

[0003] As the problems of smoking and health attract more and more attention, it is an inevitable development trend of cigarettes to improve the smoking safety of cigarettes, increase health care functions, and reduce harmful components in cigarette smoke. Therefore as soon as cigarette varieties such as ginseng cigarettes and peppermint cigarettes appear on the market, materials with unique functions or tastes such as ginseng and peppermint are added in shredded tobacco.

Examples

Embodiment 1

[0020] a. Put the jujube, which has been washed, removed impurities, and pitted, in an oven at 60°C for 24 hours, and then pulverize it twice with a traditional Chinese medicine grinder to 40 mesh;

[0021] B, get the jujube powder material that step a gained, carry out dimethyl ether subcritical critical extraction under the following conditions: extraction pressure 0.61Mpa, extraction temperature 25 ℃; With 95% ethanol as entrainer, ethanol consumption is jujube powder 3 times of the material (weight ratio). Extraction time 1.5h;

[0022] c. After the extraction is finished, the extraction mixture enters the separation tank, and the extraction solvent is separated by the principle of vacuum evaporation to obtain the jujube subcritical extract.

[0023] After the jujube extract is dissolved in 95% ethanol solution, it is added to the shredded tobacco in the feeding process by spraying, and the dosage of the jujube extract is 0.05% of the mass of the shredded tobacco.

Embodiment 2

[0026] a. The jujubes that have been washed, removed impurities, air-dried and pitted are placed in an oven at 70°C and dried for 24 hours, and then pulverized twice with a traditional Chinese medicine pulverizer to 50 mesh;

[0027] b. Take the jujube powder obtained in step a, and carry out butane subcritical extraction under the following conditions: extraction pressure 0.34Mpa, extraction temperature 35°C; 70% ethanol as entrainer, ethanol consumption is jujube powder 2 times (weight ratio). Using dimethyl ether subcritical extraction method to extract jujube powder for 1.0h;

[0028] c. After the extraction is finished, the extraction mixture enters the separation tank, and the extraction solvent is separated by the principle of vacuum evaporation to obtain the jujube subcritical extract.

[0029] After dissolving the above-mentioned jujube extract in 95% ethanol solution, it is added to the shredded tobacco in the feeding process by spraying, and the dosage of the jujub...

Embodiment 3

[0032] a. Put the jujube, which has been washed, removed impurities, and pitted, in an oven at 80°C for 24 hours, and then pulverize it twice with a traditional Chinese medicine grinder to 60 mesh;

[0033] B, get the jujube powder material that step a gained, carry out propane subcritical critical extraction under the following conditions: extraction pressure 0.45Mpa, extraction temperature 45 ℃; With 95% ethanol as entrainer, ethanol consumption is the jujube powder material 5 times (weight ratio). The jujube powder was extracted by dimethyl ether subcritical extraction method for 0.5h;

[0034] c. The extraction mixture enters the evaporation system after solid-liquid separation, and under the action of a compressor and a vacuum pump, the extraction agent is converted from a liquid state to a gas state according to the principle of reduced-pressure evaporation, thereby obtaining the jujube extract.
