Problems solved by technology

[0004] Since the solvent used in the production of tobacco flakes is water, there is no selective separation of the extracted components, and it is difficult to effectively control the chemical composition of the extract during the production process, making it difficult to stabilize the chemical composition of the produced tobacco flakes

Abstract

The invention provides a method for regulating sugar, nitrogen and nicotine of extract of papermaking-method reconstituted tobacco. The method has the advantages that the content of the total nitrogen, water-soluble total sugar and nicotine of the required concentrated solution is set, concentrating is performed according to the preset value of the total nitrogen, water-soluble total sugar and nicotine of the extract during concentrating, the concentration is ended when the content of the total nitrogen, water-soluble total sugar and nicotine reaches the set value or the content of one of the total nitrogen, water-soluble total sugar and nicotine reaches the set value and the content of the other two of the total nitrogen, water-soluble total sugar and nicotine slightly exceeds the set value, the content, reaching the set value first, of the total nitrogen, water-soluble total sugar and nicotine is finely regulated according to the set value reaching sequence after the concentration, the content of the total nitrogen, water-soluble total sugar and nicotine can be regulated, the total nitrogen content of the concentrated solution is regulated by using protease, the nicotine content of the concentrated solution is regulated by using tannin precipitation, and the water-soluble total sugar content of the concentrated solution is regulated by using an ethanol precipitation method. The method has the advantages that the chemical components of the extract can be effectively controlled, and the fragrance, harmony, pungent smell and aftertaste of tobacco sheets are improved.

Description

technical field [0001] The invention relates to the field of reconstituted tobacco leaves by a papermaking method, in particular to a method for regulating sugar, nitrogen and alkali in the extract liquid of reconstituted tobacco leaves by a papermaking method. Background technique [0002] Paper-making reconstituted tobacco, also known as paper-making tobacco sheet, is a regenerated product that uses discarded tobacco stems, tobacco dust, and low-grade tobacco leaves in the cigarette production process as raw materials to make sheets or filaments through the same process as papermaking. Adding it to cigarettes, on the one hand, can properly reduce the cost of cigarettes; on the other hand, it can adjust the physical properties and chemical components of cigarettes to a certain extent, and reduce the tar content, thereby helping to improve the quality of cigarettes. [0003] The process is to use tobacco stems, tobacco powder and low-grade tobacco leaves as raw materials, af...
