Abstract
The invention provides a mixed reconstituted tobacco and a preparation method thereof, and the preparation method comprises the following steps: 1) forming tobacco raw material components and wood pulp into tobacco solid matters, and forming the tobacco solid matters into a tobacco sheet base; 2) coating a tobacco sheet base with the coating liquid, and baking to obtain a mixed type reconstituted tobacco; the tobacco raw material components comprise stem fibers and tobacco leaf fragment powder formed by defibering tobacco stems; the coating liquid comprises the following components in percentage by weight: 0.05-1.0% of food gum, 2.0-5.0% of calcium carbonate powder, 0-2.0% of flavoring agent, 0-5.0% of humectant, and the dispersing agent of the coating liquid is a concentrated solution of tobacco extract. According to the application, calcium carbonate powder is added into the coating liquid, so that the adhesion force of the surface of the reconstituted tobacco is reduced; by adding the food gum into the coating liquid, the filler and the fine fiber on the surface of the tobacco sheet base and the calcium carbonate powder in the coating liquid are adsorbed, the adhesive force is improved, the powder falling rate of the surface of the reconstituted tobacco is reduced, and the ash content and the product yield are improved.
Description
Technical Field
The invention relates to the technical field of reconstituted tobacco, in particular to mixed reconstituted tobacco and a preparation method thereof.
Background
Compared with the traditional flue-cured tobacco type cigarette, the blended type cigarette has great advantages in the aspects of raw material selection and use, internal smoking taste, safety, economy and the like, has become the most popular cigarette type internationally, and the domestic cigarette sales is in a decline situation year by year in recent years. Therefore, from the perspective of developing the global consumer market and from the perspective of smoking and health, the design level of the blended cigarettes in China is improved as soon as possible, the blended cigarettes in China are developed, the international competitiveness of the blended cigarettes in China is continuously improved, and the blended cigarettes in China become an important task facing the tobacco industry.
The reconstituted tobacco has the characteristics of small density, high porosity, good combustibility and large filling capacity, and is a powerful means for reducing tar and harm of cigarettes; and secondly, the reconstituted tobacco has the characteristic of adjustable and controllable components, has more stable internal quality than natural tobacco, and can make up the quality defect of the tobacco caused by the inedibility of natural conditions in the planting process by an industrial technical means. Therefore, reconstituted tobacco has become an indispensable and important component of cigarette formulations.
The cigarette market in China has been dominated by the flue-cured tobacco type for a long time, and the strength of various tobacco enterprises on development and technical research of mixed type reconstituted tobacco products is relatively deficient. At present, research mainly focuses on developing reconstituted tobacco with a certain single style characteristic, such as patents of manufacturing process of reconstituted tobacco with burley tobacco characteristics, preparation method of mixed reconstituted tobacco with partial burley tobacco style, production method of reconstituted tobacco with aromatic tobacco type paper-making method and the like, even if the preparation technology of mixed reconstituted tobacco is patents of manufacturing method of mixed paper-making tobacco sheets, preparation and application of mixed paper-making reconstituted tobacco and the like, the feeding formula or the processing method mainly aims at increasing fragrance and supplementing fragrance, the compatibility of the integral fragrance style or leaf group formula of mixed cigarette products is not considered, the harmony and the internal smoking taste of various types of tobacco raw materials of mixed type reconstituted tobacco with the fragrance are balanced in a targeted manner, and the existing research does not generate environmental pollution such as dust caused by hair falling and powder falling in the processes of reconstituted tobacco production and shredding, and the problem that the adhesion is easy to occur between the reconstituted tobacco leaves and the reconstituted tobacco sheets and cake blocks are formed due to the sticky surface of the reconstituted tobacco is solved.

In view of the defects of the prior art, the invention aims to provide a mixed type reconstituted tobacco and a preparation method thereof, which are used for solving the problems that the mixed type cigarette of the mixed type reconstituted tobacco in the prior art has no obvious aroma style, poor sensory taste, dust pollution caused by the phenomenon of hair and powder falling in the production and shredding process, low tobacco sheet base strength of the reconstituted tobacco and easy cake formation caused by surface stickiness.
To achieve the above objects and other related objects, the present invention includes the following technical solutions.
A preparation method of mixed reconstituted tobacco comprises the following steps:
1) forming tobacco solid matters by using tobacco raw material components and wood pulp, and forming the tobacco solid matters into a tobacco sheet base through pulping and papermaking;
2) coating the tobacco sheet base with a coating liquid, and baking to obtain the mixed reconstituted tobacco;
the tobacco raw material components comprise stem fibers and tobacco leaf fragment powder formed by defibering tobacco stems;
based on the total weight of the coating liquid, the coating liquid comprises the following components in percentage by weight: 0.05-1.0 wt% of food gum, 2.0-5.0 wt% of calcium carbonate powder, 0-2.0 wt% of flavoring agent and 0-5.0 wt% of humectant, wherein the dispersing agent of the coating liquid is a concentrated solution of a tobacco extract.

The softness and smoke concentration improvement effect of the mixed reconstituted tobacco is not obvious due to the excessively low addition of the humectant, and the tobacco concentrated solution is excessively diluted due to the excessively high addition, so that the proportion of the tobacco concentrated solution coated on the base sheet is remarkably reduced, and the sensory quality of the mixed reconstituted tobacco is influenced.
Preferably, the flavoring agent comprises the following components in parts by weight: 10-15 parts of cocoa extract, 5-10 parts of burley tobacco extract, 4-8 parts of oriental tobacco extract, 1-3 parts of apricot extract, 3-6 parts of apple juice, 3-5 parts of licorice powder, 4-8 parts of plum extract, 25-50 parts of water and 8-10 parts of propylene glycol.
