Problems solved by technology

[0003] At present, the preparation of the coating solution for tobacco sheet is prepared by blending tobacco extract with additional spices, combustion enhancers, flow aids, calcium carbonate and other auxiliary materials. The extraction processes of tobacco materials mainly include water extraction, alcohol extraction, and ion exchange resin. The extracts prepared by these methods are high in protein, macromolecular sugars, pectin, and lignin. Tobacco sheets made from this extract have flavor defects such as heavy miscellaneous gas and strong irritation, which affect their use in cigarettes. Therefore, the current coating solution for tobacco sheets needs to add exog

Abstract

The invention discloses tobacco sheet coating liquid and a preparation method thereof. The preparation method comprises the steps of preparing alkalified tobacco powder, extraction, separation, concentration and the like. The extraction is performed by adopting an organic solvent, wherein a tobacco extract is mainly a micromolecular aroma substance with very low contents of the components such as protein and pectin, besides, the tobacco extract is not added with any exogenous auxiliary materials, and is directly used as the coating liquid for tobacco sheet, thus, prepared tobacco sheet cigarette paper reserves the original aroma of tobacco, the coating liquid hardly contains the components such as the protein and the pectin, and hence, irritation to the oral cavity is reduced, and the smoke panel test effect is improved.

Description

【Technical field】 [0001] The invention belongs to the technical field of tobacco processing. More specifically, the present invention relates to a coating liquid for tobacco sheets, and also relates to a preparation method of the coating liquid. 【Background technique】 [0002] Tobacco sheet, also known as reconstituted tobacco leaf, originated in the 1950s. It is made of tobacco waste such as tobacco stems, shredded tobacco, and tobacco dust as raw materials to make sheet or silk regenerated products, which are used as cigarette fillers. At present, there are three main methods for producing tobacco flakes at home and abroad: roll pressing, thick pulp method and papermaking method. Compared with the rolling method and the thick pulp method, the preparation of tobacco sheets by the papermaking method has the following advantages: it can effectively reduce the harmful substances in cigarettes (especially the tar content); effectively stabilize the intrinsic quality of cigaret...
