A method for improving the aroma quality of papermaking reconstituted tobacco leaves in the papermaking and forming section

Abstract

The method of improving the aroma quality of reconstituted tobacco leaves in the reconstituted tobacco leaf production section is to disperse the aroma substances with a particle size of 15-200 μm in the retention and drainage aid with a mass concentration of 0.05-1.00% In the aqueous solution, the retention and drainage aid aqueous solution dispersed with flavoring substances is added to the slurry used to prepare reconstituted tobacco leaves, the slurry is formed by papermaking to obtain a reconstituted tobacco leaf base sheet, and the reconstituted tobacco leaf base sheet is dried, coated, and reconstituted. Drying and cutting to obtain the target aroma reconstituted tobacco leaf product. In the present invention, the aroma substance is mixed into the online forming slurry to directly make the base sheet, and the aroma substance is evenly distributed in the interwoven fibers, so that the base sheet itself has the target aroma component, and the uniformity is good, and the reconstituted tobacco leaf product obtained has a characteristic aroma. Obvious, long-lasting aroma, easy to store, can further improve the aroma quality of reconstituted tobacco products.

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...

[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
