Problems solved by technology

In the above method, the agarwood raw material is all pulped together with the tobacco raw material. Due to the poor pulping performance of the agarwood raw material, the agarwood slurry obtained by pulping has many fine fibers, and the retention rate is low during the papermaking process. Loss of white water lead...

Abstract

The invention relates to an aquilaria sinensis reconstituted tobacco preparation method used in a laboratory by adopting the sandwich method. The preparation method comprises the following steps: extracting crushed leaves of aquilaria sinensis or agalloch eaglewood with an ethanol aqueous solution serving as a solvent, wherein the volume ratio of the crushed leaves of aquilaria sinensis or agalloch eaglewood to the ethanol aqueous solution is 55-65 percent, and material-to-liquid ratio is 1:6-1:10; enabling an extracted solid phase to be used for pulping and concentrating a liquid phase into an aquilaria sinensis concentrate with a density of 1.15-1.20 g/cm<3>; performing primary extraction on a reconstituted raw material by taking water as a solvent according to the material-to-liquid ratio of 1:7 to 1:8, performing solid-liquid separation, performing secondary extraction on a solid-phase part by taking water as a solvent according to the material-to-liquid ratio of 1:6 to 1:7, enabling a solid phase obtained after secondary extraction to be used for pulping, combining a primary liquid-phase part and a secondary liquid-phase part, concentrating with a rotary evaporator to obtain a tobacco concentrate with a density of 1.18 g/cm<3> ; preparing the aquilaria sinensis reconstituted tobacco through the steps of pulping, papermaking and forming, coating, sample preparation and the like. The aquilaria sinensis reconstituted tobacco prepared by adopting the preparation method has the advantages of being obvious in aquilaria sinensis aroma features, more harmonious and natural in smoke, good in comfortability and better in overall quality.

Description

technical field [0001] The invention belongs to the technical field of papermaking reconstituted tobacco leaves, and in particular relates to a method for preparing interlayer agarwood reconstituted tobacco leaves used in laboratories. Background technique [0002] Cigarettes and reconstituted tobacco leaves with agarwood style characteristics have been reported. Add shredded agarwood leaves to shredded tobacco, and China Tobacco Jiangsu has developed a 6mg ultra-thin "Suyan" agarwood cigarette. Chinese patent 201310137653.X discloses a method for preparing agarwood reconstituted tobacco leaves, which adopts extrusion method or rolling method; The method in the coating solution; the preparation method of agarwood reconstituted tobacco leaves disclosed in Chinese patent 201210165130.1 is similar to that of ZL201310207429.3. In the above method, the agarwood raw material is all pulped together with the tobacco raw material. Due to the poor pulping performance of the agarwood...
