Problems solved by technology

Patent CN102524934A discloses a reconstituted tobacco leaf coating solution component and component group chemical kitchen combination, coupling preparation and its process, which is to first process the extract through enzymatic treatment, and then integrate or couple Maillard reaction, membrane separation, column Separation, freeze separation, alcohol precipitation and other technologies are used to purify and improve the quality of the tobacco extract. The alcohol precipitation technology used is mainly to remove pectin in the extract, and the amount of ethanol used for the direct alcohol precipitation of the extract will be lower. Larger, high recycling cost, coupled with other processing technologies, complicated operation, high economic cost, and poor industrial applicability

Embodiment 1

[0016] Tobacco raw materials and added wood pulp fibers are fed at a dry weight ratio of 10:1. Tobacco raw materials such as tobacco stems and tobacco powder are extracted and separated from solid and liquid to obtain extract solids and extracts. The solids are beaten by a refiner to 20± 2 O SR, plus wood pulp, beating to 40±2 by refiner O Sr. After the tobacco stem pulp is mixed with the added wood pulp, add light calcium carbonate accounting for 7% of the dry mass of the mixed pulp to make the pulp and adjust the concentration, and carry out papermaking according to the set concentration to obtain a quantitative value of about 60g / m2 reconstituted tobacco leaf substrate.

[0017] Add the same mass of glacial acetic acid into food-grade chitosan with a deacetylation degree of 85% and a molecular weight of 50,000, add water, stir and dissolve, and prepare a chitosan solution with a mass concentration of 0.1%. According to chitosan accounts for 0.01% of the solid content of ...

Embodiment 3

[0022] Tobacco raw materials and added wood pulp fibers are fed at a dry weight ratio of 10:1. Tobacco raw materials such as tobacco stems and tobacco powder are extracted and separated from solid and liquid to obtain extract solids and extracts. The solids are beaten to 20± 2 O SR, plus wood pulp, beating to 40±2 by refiner O Sr. After the tobacco stem pulp is mixed with the added wood pulp, add light calcium carbonate accounting for 7% of the dry mass of the mixed pulp for pulp blending and thickening, and make paper according to the set concentration to obtain a quantitative value of about 60g / m2 reconstituted tobacco leaf substrate.

[0023] Add the same mass of glacial acetic acid into food-grade chitosan with a deacetylation degree of 90% and a molecular weight of 50,000, add water, stir and dissolve, and prepare a chitosan solution with a mass concentration of 0.5%. According to chitosan accounts for 0.06% of the solid content of the extract solution, the chitosan so...

Abstract

The invention provides a method for improving the sensory quality of reconstituted tobacco. Tobacco raw materials are extracted and separated to obtain extraction solution solid and an extraction solution, the extraction solution solid and added wood pulp are pulped and then mixed, and papermaking and forming are conducted to obtain a reconstituted tobacco substrate; the extraction solution is concentrated to obtain a tobacco concentrated solution, then materials are added to prepare coating liquid, the reconstituted tobacco substrate is coated with the coating liquid, and the papermaking method reconstituted tobacco can be obtained through drying and slitting procedures. The method is characterized in that after the extraction solution is extracted and before concentration, the extraction solution is subjected to flocculation purification through chitosan liquid, and then alcohol precipitation purification treatment is conducted after pre-concentration. The chitosan flocculation and alcohol precipitation treatment technology are comprehensively used, the reconstituted tobacco extraction solution is purified, protein, pectin and other large molecules are selectively removed, and the sensory quality of the papermaking method reconstituted tobacco is improved.

Description

technical field [0001] The invention relates to the technical field of reconstituted tobacco leaves by papermaking, in particular to a method for improving the sensory quality of reconstituted tobacco leaves. Background technique [0002] Paper-making method reconstituted tobacco leaves is the use of paper-making technology to extract and squeeze tobacco stems, chips, low-grade tobacco leaves, and packaged tobacco powder to achieve solid-liquid separation. After the extract is purified, refined and concentrated, it is formulated into a coating solution according to the formula. After the coating process and the film base are coated, they are dried and cut to obtain the final finished reconstituted tobacco leaves. Since the raw materials of reconstituted tobacco leaves have undergone the above series of physical and chemical separation and recombination operations, harmful components can be removed as required, and the tar content is significantly lower than that of cigarette...
