Problems solved by technology

In the prior art, there are also some applications of tobacco particles, but these particles mostly use porous materials such as silicate rock, activated carbon, sepiolite, bentonite, medical stone, zeolite and some synthetic molecular sieves as carriers. A small amount of loaded aroma components, with or without, has certain advantages in reducing tar and harm, but the compensation function of tobacco aroma is not obvious, and these tobacco particles are only applied to filter rods

preparation example Construction

[0013] A preparation method of tobacco extract particles, such as figure 1 As shown, the preparation method is as follows:

[0014] (1) Take tobacco leaves and / or tobacco stems and chop them up, extract with water or ethanol or ether as a solvent, settle and filter to obtain tobacco extract, then concentrate to a relative density of 1.00-1.30 and control the temperature at 20-40°C , to obtain the tobacco extract concentrate;

[0015] (2) According to the mass ratio of β-cyclodextrin: tobacco flavor is 1 to 3:1, and the inclusion time of tobacco flavor and β-cyclodextrin is 1 / 5 to 3 hours to obtain flavor and β-cyclodextrin inclusion compound, and then spray-dry spices, β-cyclodextrin inclusion compound and tobacco extract concentrate to obtain tobacco spray-dried powder; or directly spray-dry tobacco extract to obtain tobacco spray-dried powder;

[0016] (3) Tobacco spray-dried powder is dry or wet granulated by adding excipient materials to obtain tobacco extract granules. ...

Embodiment 5

[0028]The tobacco stems were chopped and extracted with 10 times aqueous solution under reflux for 1.5 hours, filtered, and the filtrate was concentrated under reduced pressure at a vacuum degree of 0.05 MPa to a relative density of 1.2 at a temperature of 25-30°C to obtain a tobacco extract concentrate. β-cyclodextrin and cinnamaldehyde were clathrated at a mass ratio of 2.5:1 for 1.5 hours to obtain the clathrate of cinnamaldehyde and β-cyclodextrin. The cinnamaldehyde is spray-dried together with the β-cyclodextrin inclusion compound and the tobacco extract concentrate to obtain the spray-dried powder. Glycyrrhiza licorice was crushed and sieved to 120 mesh, mixed evenly with spray-dried powder, lactose, microcrystalline cellulose, and talcum powder, and the mixed powder was made into 40-80 mesh granules by dry method. The total amount of lactose, microcrystalline cellulose, and talcum powder added is twice the mass of the spray-dried powder, and the added amount of the lic...

Embodiment 6

[0030] The tobacco stems were chopped and extracted with 10-fold aqueous solution under reflux for 1.5 hours, filtered, and the filtrate was concentrated under reduced pressure at a vacuum of 0.05 MPa to a relative density of 1.1 at a temperature of 20-30°C to obtain a tobacco extract concentrate. The β-cyclodextrin and cinnamaldehyde were clathrated at a mass ratio of 2:1 for 1.5 hours to obtain the clathrate of cinnamaldehyde and β-cyclodextrin. The cinnamaldehyde is spray-dried together with the β-cyclodextrin inclusion compound and the tobacco extract concentrate to obtain the spray-dried powder. In addition, rice was crushed and sieved to 80 meshes, mixed evenly with spray-dried powder, microcrystalline cellulose, soluble starch, and liquid paraffin, and made into granules. The total amount of microcrystalline cellulose, soluble starch, and liquid paraffin is 0.5 times the mass of the spray-dried powder, and the amount of added rice flour is 1 / 10 of the mass of the spray-...

Abstract

The invention relates to a preparation method of tobacco extract granules, which comprises the following steps: firstly taking and cutting up tobacco leaves and / or tobacco stalks, taking water or ethanol or ethyl ether as a solvent for extraction, settling and filtering to obtain tobacco extract, then concentrating to the relative density of 1.00-1.30, and controlling the temperature to 20-40 DEGC to obtain tobacco extract concentrate or tobacco extractum; and including beta-cyclodextrin and flavouring essence for tobacco according to the mass ratio of 1-3:1 with the inclusion time of 1 / 5-3 hours to obtain a flavouring essence and beta-cyclodextrin inclusion compound, and then spray drying the flavouring essence for tobacco and beta-cyclodextrin inclusion compound and the tobacco extractconcentrate together to obtain tobacco spray dried powder; or directly spray drying the tobacco extractum to obtain the tobacco spray dried powder; and then adding excipient material to the tobacco spray dried powder for dry method or wet method granulation to obtain the tobacco extract granules. The tobacco extract granules obtained in the method disclosed by the invention are applied to cigarettes to improve the tar and harm reduction effect of the cigarettes, and can be used for aroma compensation, the utilization rate of waste tobacco leaf raw material is improved, and the cost of the cigarettes is reduced.

Description

technical field [0001] The invention belongs to the technical field of tobacco extract preparation methods. Background technique [0002] Healthy smoking has become a common concern all over the world, and reducing tar and harm is the unshirkable responsibility of the cigarette industry. However, while reducing tar and harm, it is inevitable that there will be problems of insufficient aroma and unobvious characteristic aroma. Here, the characteristic aroma in the flue gas and the compensation technology of the aroma concentration are worthy of further research and development. [0003] Tobacco extracts are widely used in cigarettes by selectively extracting the aroma components in tobacco. Chinese patent application number 200610048609.1 discloses a fermented tobacco extract and its preparation method, and Chinese patent application number 200910027400.0 discloses a tobacco extract preparation method and its application. These two documents describe the extraction and prep...
