preparation example Construction

[0022] see figure 1 , the present invention provides a kind of preparation method of tobacco pigment, comprising the following steps:

[0023] 1.1 Add the waste tobacco material into the solvent, extract the solid-liquid separation after a predetermined time, and collect the extract.

[0024] As an example, the extraction method in the step 1.1 includes: adding a solvent to the waste tobacco material at a mass solid-liquid ratio of 1:5-10, stirring and extracting at 20-60° C. for 40-150 minutes.

[0025] As an embodiment, after the extraction and solid-liquid separation in the above steps are completed, the obtained slag is extracted and solid-liquid separated again according to the above operation steps, and the extracted liquids from the two extractions are combined.

[0026] As an example, the step of microfiltration to remove impurities is also performed on the extract obtained in the step 1.1, and after obtaining the extract after the dialysis to remove impurities, the p...

Embodiment 1

[0038] Add 2.0Kg of tobacco powder and 10.0Kg of water into the extraction container, stir evenly, and stir and soak for 2 hours at room temperature for extraction. Solid-liquid separation. Collect the extract, extract the slag once again according to the above conditions, collect the extract and merge with the previously separated extract;

[0039] The collected tobacco dust extract is subjected to microfiltration to remove impurities, and the dialysate of the microfiltration process is collected;

[0040] A chromatography column (Φ=10mm, h=50mm) filled with macroporous resin was carried out on the dialysate after the above-mentioned impurity removal and separation for adsorption (column separation). Adjust the sample pump to control the flow rate of the upper column at about 120mL / min. After the sample is loaded, wash the residual liquid in the column with 6.0Kg deionized water;

[0041] Use 10.0Kg of eluent solution to desorb the components adsorbed on the macroporous resin...

Embodiment 2

[0045] 3.0Kg of tobacco stems and 18.0Kg of water were added to the extraction vessel, stirred evenly, and stirred and extracted at 60° C. for 1 hour. Solid-liquid separation. Collect the extract, extract the slag once again according to the above conditions, collect the extract and merge with the previously separated extract;

[0046] The collected tobacco dust extract is subjected to microfiltration to remove impurities, and the dialysate of the microfiltration process is collected;

[0047] A chromatography column (Φ=10mm, h=50mm) filled with macroporous resin was carried out on the dialysate after the above-mentioned impurity removal and separation for adsorption (column separation). Adjust the sample pump so that the flow rate of the upper column is controlled at about 120mL / min. After the sample is loaded, wash the residual liquid in the column with 4.0Kg deionized water;

[0048] Use 10.0Kg of eluent solution to desorb the components adsorbed on the macroporous resin,...

Abstract

The invention discloses a method for preparing tobacco pigment. The raw material of the invention is taken from waste tobacco itself. The prepared tobacco pigment will not cause adverse effects when used in tobacco products. The color tone is natural and true, close to the color of natural tobacco leaves. . The present invention can effectively remove protein, pectin, excess sugar, nicotine, inorganic salts, etc. It has high color value and good purity, and it will not bring any miscellaneous smell when it is used in tobacco products. In addition, because the extraction and purification temperature of the present invention is relatively low, the damage to the heat-sensitive substances in the tobacco is reduced, and the breath of the tobacco itself is retained.

Description

technical field [0001] The invention relates to the field of tobacco technology, in particular to a preparation method of tobacco pigment. Background technique [0002] As the development of Chinese-style cigarettes requires cigarette coke reduction, various coke reduction techniques have been adopted by cigarette manufacturers one after another. Among them, mixing reconstituted tobacco leaves, expanded cut tobacco, cut stems, expanded cut stems and even reconstituted cut stems in shredded cigarettes is an effective and better method. It is understood that this method is currently widely used in various brands of cigarettes. production. The following problems are: due to the restriction of the coating rate in the production process of reconstituted tobacco leaves; the characteristics of the bulking agent used in the expansion process of the expanded cut tobacco, and the increase in the volume of the tobacco stems after expansion, more or less lead to the blending of materia...
