Preparation method of Mao cigarette extract and application of Mao cigarette extract to cigarette filter stick

Abstract

The invention relates to a preparation method of a Mao cigarette extract, specifically comprising the steps that Shifang County Mao cigarette as a raw material is smashed and is subjected to subcritical extraction, chromatographic column separation and vacuum concentration to prepare the Mao cigarette extract. The invention also relates to application of the Mao cigarette extract to a cigarette filter stick, specifically comprising the steps that the Mao cigarette extract is diluted by using an ethanol and propylene glycol mixed solvent, and then is mixed with glycerol triacetate according to a certain ratio, so as to prepare a Mao cigarette type plasticizer, and afterwards the cigarette filter stick is prepared according to a conventional filter stick process. Through the application of the Mao cigarette type plasticizer, a cigarette has a peculiar sun-cured tobacco taste in smoke, a sour and sweet feeling is added, the agreeable aftertaste is more mellow, the enjoyment and richness of the smoke are enhanced, and the smoking quality is obviously improved.

Description

technical field

[0001] The invention relates to a preparation method of hair tobacco extract and its application in cigarette filter rods. The application of this technology can improve the pleasure and richness of the smoke, and improve the smoking quality of cigarettes. Background technique

[0002] In recent years, in order to meet consumers' dual pursuit of cigarette consumption and health, the tobacco industry has implemented tar reduction and harm reduction projects. However, it is inevitable to lose the aroma and taste of the cigarette itself while reducing the tar and harm, and adding tobacco extract to the cigarette filter rod is an important means to keep the taste of the cigarette. Tobacco extract is extracted from tobacco and contains small molecule tobacco aroma substances. Its aroma can be well combined with cigarettes, and it can restore the original aroma of tobacco to the greatest extent while reducing the tar content. At the same time, adding tobacco extr...

Embodiment 1

[0016] Weigh 1 kg of shredded Shifang Mao tobacco leaf fragments, put them into the extraction kettle, start the vacuum pump to extract the air in the extraction kettle, use butane as the main solvent, and add it into the extraction kettle according to the mass ratio of tobacco leaves: main solvent = 1:2 , adding 5% ethanol as an entrainer, under the process conditions of a temperature of 45°C and a pressure of 0.3Mpa, continuous extraction twice, each extraction time is 0.5h. After the extraction is completed, the fume extract is obtained by separating in the separation kettle. Pass the Maoyan extract through the chromatographic column, the adsorbent is macroporous resin, pass through the column with 2 times the amount of raw material distilled water, the flow rate is 3BV / h, discard the water eluent; then use 2 times the amount of 20% ethanol as the raw material to elute, The flow rate was 3BV / h, and the eluent was discarded; finally, 3 times the amount of 70% ethanol was use...

[0020] Weigh 1 kg of crushed Shifang Mao tobacco leaf fragments, put them into the extraction kettle, start the vacuum pump to extract the air in the extraction kettle, use isobutane as the main solvent, and add it to the extraction kettle according to the mass ratio of tobacco leaves: main solvent = 1:2.5 10% ethanol was added as an entrainer, and under the process conditions of a temperature of 35°C and a pressure of 0.5Mpa, continuous extraction was performed twice, and each extraction time was 1h. After the extraction is completed, the fume extract is obtained by separating in the separation kettle. Pass the Maoyan extract through the chromatographic column, the adsorbent is macroporous resin, pass through the column with 2 times the amount of raw material distilled water, the flow rate is 2BV / h, discard the water eluent; then use 2 times the amount of 50% ethanol as the raw material for elution, The flow rate was 2BV / h, and the eluent was discarded; finally, 3 times the a...

[0024] Weigh 1kg of pulverized tobacco leaf fragments, put it into the extraction kettle, start the vacuum pump to extract the air in the extraction kettle, use butane as the main solvent, and add it into the extraction kettle according to the mass ratio of tobacco leaves: main solvent=1:3, Add 15% ethanol as an entrainer, and extract twice continuously at a temperature of 25°C and a pressure of 0.8Mpa, and each extraction time is 0.5h. After the extraction is completed, the fume extract is obtained by separating in the separation kettle. Chromatographic column separation: pass the Maoyan extract through the chromatographic column, the adsorbent is macroporous resin, use 2 times the amount of raw material distilled water to pass through the column, the flow rate is 3BV / h, discard the water eluent; then use 30% ethanol as raw material 2 Double volume elution, flow rate 2BV / h, discard the eluent; finally use 70% ethanol raw material for 3 times volume elution, flow rate 2BV / h, c...
