Problems solved by technology

[0003] In a nutshell, water solvents are currently used as extraction media for reconstituted tobacco powder raw materials. Although water solvents can better extract the polar components of tobacco powder raw materials under appropriate process conditions, they are not suitable for the extraction of a considerable number of key aroma components. less efficient
The use of weaker polar extraction media such as ethanol, although the extraction efficiency of key aroma components has been improved, has greatly increased the cost.

Embodiment 1

[0020] In this example, tobacco powder is used as raw material, and it is firstly extracted by a three-stage countercurrent extraction process. The extraction conditions of each stage are: the mass ratio of tobacco powder to extraction medium is 1:5, the extraction temperature is 50°C, and the extraction time is 40min. During the extraction process, the following operations are performed to realize the dynamic gradient change of the pH value of each extraction mixed system in the three-stage countercurrent extraction process:

[0021] (1) In the three-stage extraction section, pump continuously and uniformly the concentration of 1.13×10 -2 mol / L citric acid monohydrate solution is used as the extraction medium, and the pumping speed is 0.125m 3 / min, the total pumping volume of each batch is 5m 3 , so that the pH value of the three-stage extraction mixed system is about 3.1;

[0022] (2) In the secondary extraction section, the potassium hydroxide solution whose concentrati...

Embodiment 2

[0030] In this embodiment, the same tobacco dust raw material is subjected to three-stage countercurrent extraction in the same way, and the reconstituted tobacco leaf substrate is made in the same way, the only difference being:

[0031] The concentration of monohydrate citric acid solution is 3.39 * 10 in the step (1). -2 mol / L, the concentration of the potassium hydroxide solution in the step (2) is 3.39mol / L, and the concentration of the potassium hydroxide solution in the step (3) is 1.695mol / L, and the gained sample is marked as S2.

Abstract

The invention discloses a dynamic gradient pH three-stage countercurrent extraction process for tobacco waste raw materials of reconstituted tobacco. In the process of extracting the tobacco waste raw materials by a three-stage countercurrent extraction process in the prior art, acid liquor and alkali liquor with certain concentration and flow rate are uniformly pumped into an extraction system to realize dynamic gradient change of a pH value of an extraction and mixing system at each stage in the three-stage countercurrent extraction process. The process provided by the invention can obviously increase extraction efficiency of aromatic components in the tobacco waste raw materials, greatly improve sensory quality of a finished product of reconstituted tobacco, and also better regulate balance of chemical components in the reconstituted tobacco. In addition, a method of the invention has advantages of low cost, remarkable effect and relatively good application prospect.

Description

technical field [0001] The invention relates to the technical field of production of reconstituted tobacco leaves by the papermaking method in the tobacco industry, in particular to a process for three-stage countercurrent extraction of tobacco powder raw materials. Background technique [0002] Paper-making method reconstituted tobacco is based on the principle of paper-making, using low-grade or waste tobacco raw materials that cannot be directly used in cigarette products, and undergoes extraction, pulping, substrate sheet making, coating, drying, slitting, flavoring and other processes. production. Since the effective tobacco components in the coating solution are mainly derived from tobacco powder raw materials, the extraction process of tobacco powder is directly related to the final quality of the finished reconstituted tobacco leaf. In the extraction of tobacco powder, many studies aim to improve the efficiency and quality of tobacco powder extraction, such as Huang...
