Description
Technical Field
The invention belongs to the field of tobacco products, and particularly relates to a method for simultaneously carrying out enzymolysis and alcoholization on reconstituted tobacco, the reconstituted tobacco obtained by the method and application of the reconstituted tobacco in tobacco products.
Background
The reconstituted tobacco is a tobacco recombinant product prepared by a series of procedures with tobacco stems, crushed tobacco leaves, tobacco powder, added fibers and the like as main raw materials. The reconstituted tobacco is added into the cigarette, so that the cost can be reduced, the utilization rate of raw materials can be improved, and the tar content in the main stream smoke of the cigarette can be adjusted.
The tar in the main stream smoke of the cigarette manufactured by reconstituted tobacco mainly comes from the following sources: the poor combustibility of pectin in reconstituted tobacco is a direct reason for tar; the pectin is interwoven with other macromolecular substances, so that the full combustion of the other macromolecular substances is influenced, and the tar content is further increased. The main factor that the carbon monoxide content in the mainstream smoke of cigarettes prepared from reconstituted tobacco is generally high and the carbon monoxide content has become a limitation on the wide use of the reconstituted tobacco is mainly due to the following reasons: the pectin in the reconstituted tobacco has poor combustibility, releases a large amount of carbon monoxide under the smoldering condition, is easy to coke in the pyrolysis process, is not beneficial to the integral combustion of the reconstituted tobacco, and indirectly increases the release amount of the carbon monoxide.
For reducing the tar content and the carbon monoxide content in the mainstream smoke of the cigarette manufactured by the reconstituted tobacco, the conventional method intervenes and controls the preparation process of the reconstituted tobacco at present, but the method has the advantages of little effect, fussy operation and poor controllability.
Alcoholization refers to an operation of stacking the prepared tobacco leaves in a storage according to a certain requirement and preserving the tobacco leaves for a period of time under a certain temperature and humidity. The main function of alcoholization is to make the tobacco leaf color uniform and properly deepen and improve the tobacco leaf sensory quality. However, no report is available today for reducing the tar content or the carbon monoxide content in the mainstream smoke of cigarettes made from reconstituted tobacco through an alcoholization process.
At present, a tobacco alcoholization method capable of reducing tar content and carbon monoxide content in main stream smoke of cigarettes prepared from reconstituted tobacco is needed, and sensory quality of the reconstituted tobacco is improved.
