Coating agent capable of increasing content of organic nitrogen in tobacco reconstructed by means of papermaking method and preparation method and application of coating agent

Abstract

The invention discloses a coating agent capable of increasing the content of organic nitrogen in tobacco reconstructed by means of a papermaking method and a preparation method and application of thecoating agent. The method includes the following steps of 1, adding a mixture of tobacco stems, tobacco powder and wood fiber into water, adding reducing sugar, inorganic ferric salts and inorganic ammonium salts at the same time, adjusting the pH to be 6.0-8.5 and the temperature to be 50-70 DEG C, conducting extraction for 1-3 hours, and then obtaining a mixed solution; 2, conducting solid-liquid separation on the mixed solution obtained in step 1, adding calcium carbonate into liquid, conducting mixing for 20-60 min, and conducting centrifugation and filtering to obtain a reconstructed tobacco liquid extract; 3, condensing the reconstructed tobacco liquid extract obtained in step 2 at 50-70 DEG C to obtain a condensed reconstructed tobacco liquid, namely the coating agent capable of increasing the content of organic nitrogen in the tobacco reconstructed by means of the papermaking method. By means of the coating agent, residues of the ammonium salts added into a product are reduced,the content of organic nitrogen in the reconstructed tobacco product is increased, the sensory quality of the prepared reconstructed tobacco product is similar to that of tobacco, and the smell of burning paper and the smell of wood are reduced significantly.

Description

technical field [0001] The invention belongs to the technical field of cigarette production, and in particular relates to a coating agent for increasing organic nitrogen in reconstituted tobacco leaves by a papermaking method, a preparation method and application thereof. Background technique [0002] The total nitrogen content is an important index to evaluate the inherent quality of tobacco products, and it is also an important basis for the design of reconstituted tobacco products. Due to the requirements of the technical characteristics of reconstituted tobacco leaves by papermaking, additional plant fibers (such as softwood fibers, hardwood fibers, flax fibers, etc.) and fillers (such as calcium carbonate, talcum powder, diatomaceous earth, etc.) have to be used in the manufacturing process ). This reduces the organic nitrogen content in reconstituted tobacco leaf products to a certain extent, which in turn affects the sensory quality of reconstituted tobacco leaf prod...

AI Technical Summary

Problems solved by technology

[0005] Although a variety of technical solutions for regulating the total nitrogen content in reconstituted tobacco leaf products have been proposed in the prior art, there are still unsolvable problems, that is, if an excessive amount of raw materials is required to increase the nitrogen content of reconstituted tobacco leaf raw materials, it will remain in the tobacco leaves. Inorganic ammonium salts, inorganic ammonium salts or residual additives will destroy the coordination and taste comfort of cigarettes, and in order to meet the requirements of product sensory quality, it is difficult to remove additives that have not participated in the reaction; Excessive addition of raw materials leads to insufficient reaction in the process of tobacco leaf extraction, the addition of raw materials is relatively low, and the nitrogen content still cannot be fully improved; if the processing process is added to remove raw materials that do not participate in the reaction, the production line needs to be rebuilt, which is time-consuming strenuous
