Method for improving aroma quality of reconstituted tobacco in papermaking forming section

Abstract

The invention discloses a method for improving the aroma quality of reconstituted tobacco in a papermaking forming section. The method comprises the following steps: dispersing a fragrant substance with the particle size of 15-200 microns into a retention and drainage aid aqueous solution with the mass concentration of 0.05-1.00% in the papermaking forming section of reconstituted tobacco production, adding the retention and drainage aid aqueous solution in which the fragrant substances are dispersed into the slurry for preparing the reconstituted tobacco, carrying out papermaking forming on the slurry to obtain a reconstituted tobacco substrate, and drying, coating, re-drying and slitting the reconstituted tobacco substrate to obtain a target fragrant reconstituted tobacco product. According to the method, the aroma substances are mixed with the net forming slurry to directly prepare the substrate aroma substances which are uniformly distributed in the interwoven fibers, so that the substrate has target aroma components and is relatively good in uniformity, the prepared reconstituted tobacco product is obvious in characteristic aroma, lasting in aroma and convenient to store, andthe aroma quality of the reconstituted tobacco product can be further improved.

Description

technical field [0001] The invention relates to the technical field of manufacturing reconstituted tobacco leaves by papermaking methods, in particular to a method for improving the aroma quality of reconstituted tobacco leaves by papermaking methods, which is applied to the forming section of reconstituted tobacco leaves by papermaking methods. Background technique [0002] Paper-making method Reconstituted tobacco leaves are made of paper-making technology, and the tobacco stems, tobacco fragments and characteristic natural plant fibers are copied and shaped into a paper-like substrate, and then the extracted tobacco-specific extract is mixed with flavors and fragrances added according to the process requirements. It is prepared as a coating solution, back-coated on the above-mentioned paper-like substrate, dried and cut. The main production process is divided into seven sections: raw material extraction, pulping and preparation of coating liquid, slurry sheet forming, sub...

Problems solved by technology

[0004] Chinese patent CN 103211289 B discloses a method for preparing reconstituted tobacco leaves with microencapsulated aroma components in the extract. The microencapsulated reconstituted tobacco leaves prepared by this method can prevent the change and loss of aroma components in subsequent processing and improve the storage stability of reconstituted tobacco leaves , improve the sensory quality of reconstituted tobacco leaves; Chinese patent CN 102864016 B discloses a microencapsulated rose essential oil and its application in tobacco, the microencapsulated rose essential oil can increase the fruity sweet aroma and improve the quality of cigarettes; the two patents The disclosed microcapsule flavors are all applied to the coating liquid in the coating process of reconstituted tobacco leaves. Although the microcapsules can improve the sensory quality of reconstituted tobacco leaves to a certain extent, they are all added to the coating liquid, and there will be occurrences in the actual production process. Coating pipe nozzle blockage, obvious product adhesion, etc.

[0005] Chinese patent CN 109349677 A discloses a reconstituted tobacco leaf with ultra-fine tobacco powder and its preparation method. The method is to apply ultra-fine tobacco powder to a thick slurry, and use the thick slurry method to prepare a reconstituted tobacco leaf product. When the product is smoked, The miscellaneous gas and irritation are more obvious, but the sensory quality of reconstituted tobacco products has not been significantly improved
