A kind of preparation method of reconstituted tobacco leaf coating liquid

Abstract

The invention provides a method for preparing a reconstituted tobacco leaf coating solution. The method is to add tap water to the mixture of tobacco stalks, tobacco powder and secondary tobacco leaves and mix them evenly, then dynamically countercurrent extract to obtain insoluble slurry and extract; filter the extract to obtain filtrate A and retentate A; use potassium dihydrogen phosphate Adjust the pH value of the retentate solution A, and add glycosidase to the retentate solution A after adjusting the pH value for enzymolysis, then add chitosan aqueous solution to the enzymolysis solution, stir and mix evenly, and take the supernatant after standing still. Filter to obtain filtrate B; combine filtrate A and filtrate B, concentrate under reduced pressure to obtain concentrate A, add sodium glutamate for Maillard reaction, add liquid fructose, stir evenly, and centrifuge to collect the filtrate. Coating solution for reconstituted tobacco leaves. The method in the present invention is energy-saving and environment-friendly, and the prepared reconstituted tobacco leaf coating liquid has a strong aroma, can enhance aroma quality, increase the fluttering feeling of smoke, reduce throat irritation, and improve oral aftertaste.

Description

technical field [0001] The invention belongs to the field of manufacturing and processing of the tobacco industry, and in particular relates to a method for preparing a coating liquid for reconstituted tobacco leaves. Background technique [0002] Reconstituted tobacco leaves, also known as reconstituted tobacco leaves and tobacco sheets, are made by reorganizing tobacco stems, tobacco dust, and some secondary tobacco leaves produced during the production and processing of tobacco or cigarettes by physical or chemical methods, and can be used as a substitute for cigarette raw materials Taste. The use of reconstituted tobacco leaves in cigarettes can effectively reduce the tar and CO content and improve the smoking quality of cigarettes. The reconstituted tobacco leaf coating solution is a liquid substance obtained after a series of treatments of the water-soluble part in the extraction process of tobacco raw materials, and is an important factor for imparting aroma style to...

AI Technical Summary

Problems solved by technology

This method only performs a simple Maillard reaction on the extract, and the resulting coating solution has insufficient aroma and is insufficient in improving the aroma of cigarettes; the invention patent (application number: 201711070249.X) is to combine stem paste, The leaf paste and tobacco flavors and fragrances are blended in a mass ratio of 30:65:5 to make a coating liquid with a solid content of 40%-46%, and the stem paste and leaf paste are blended in a mass ratio of 25:75 to make a solid content of 20%-35% % spray liquid, or use a single leaf paste or a single stem paste to prepare a spray liquid with a solid content of 20%-35%

This method only mixes different pastes or flavors and fragrances, and does not use physical or chemical methods to treat the extract itself. The obtained coating liquid has a relatively single aroma and poor application effect; the invention patent (application number: 201510332704.3 ) is to add yeast and protease to the tobacco extract to ferment, then concentrate alcohol and alcohol into a clear paste, add hot water, reducing sugar, amino acid, and carry out Maillard reaction

Although this method decomposes the macromolecules in the extract by adding yeast and protease, the above strains and enzymes can only process part of the macromolecules, which affects the application effect of the coating solution to a certain extent.
