Problems solved by technology

The tobacco materials used in new cigarettes are heated at a lower temperature, and there are still problems of low smoke concentration, insufficient aroma and satisfaction, so the traditional coating liquid preparation method still cannot meet the requirements of new cigarettes
First, the extraction method mostly uses water extraction, the process is relatively simple, and it is impossible to fully obtain the aroma substances in tobacco, especially the aroma substances with low polarity and low boiling point; second, the residue after simple extraction is directly discarded to cause aroma The loss of material and the waste of raw materials; thirdly, the process of removing macromolecules such as membrane separation is complicated and the cost is high, which limits the large-scale production to a certain extent

Abstract

A reconstituted tobacco coating liquid preparing method suitable for a novel cigarette is characterized by comprising the steps of: firstly drying and smashing a tobacco raw material, extracting with ethyl alcohol solution, and after solid liquid separation, performing concentration under reduced pressure on filtrate to obtain a tobacco alcohol extract; adding enzyme into filter residue to degrade, and after secondary solid liquid separation, performing concentration under reduced pressure on filtrate to obtain a tobacco water extract; mixing the tobacco water extract, an amino compound and polyhydric alcohols to perform heating reaction to obtain a tobacco reactant; finally proportionally mixing the tobacco alcohol extract, the tobacco reactant and a heat conduction material dispersion liquid to obtain the coating liquid. After the prepared coating liquid is subjected to perfuming treatment, a coated substrate is made into regenerated tobacco, the novel cigarette product is endowed with a thick vivid cigarette fragrance and the smoke concentration and fragrance quality are obviously improved.

Description

technical field [0001] The invention belongs to the technical field of tobacco, and in particular relates to a method for preparing a reconstituted tobacco leaf coating solution suitable for new cigarettes. Background technique [0002] The coating solution is the concentrate of tobacco extract, which is applied to the sheet base in the subsequent process to make reconstituted tobacco leaves. The control of the effective components of the coating solution determines the smoke quality of reconstituted tobacco leaves, and is a key step in the quality control of the entire process of reconstituted tobacco leaves. On the one hand, optimizing extraction conditions and improving extraction methods are the best ways to increase the extraction of active ingredients in reconstituted tobacco raw materials; on the other hand, the use of microbial and enzymatic degradation, Maillard reaction, membrane separation and other treatment technologies can be Improves the sensory quality of co...
