Problems solved by technology

Chinese patent CN102406230A discloses the method of using electrodialysis combined with ion exchange column chromatography to remove As, Pb and Cd in tobacco extract, and the removal efficiency can reach up to 90%, but this patent does not examine the effect of treatment on nicotine and cigarette sensory quality influences
While the common electrodialysis technology realizes the selective removal of ionic compounds such as chloride ions and nitrates relative to non-ionic compounds (fructose, glucose, pectin, etc.), it also usually results in the removal of effective ionic components of tobacco (nicotine and organic components). A large amount of loss of acid), which will inevitably lead to a decline in the quality of cigarette smoking

Embodiment 1

[0020] Tobacco extract was prepared from tobacco leaves, and 450mL of tobacco extract with a solid content of 8% was installed with 10 pairs of ion-exchange membranes (wherein the negative membrane was Selemion TM Monovalent anions selectively permeate the membrane, and the positive membrane is Selemion TM In the desalination chamber of the electrodialysis device of monovalent cation selective permeable membrane, the effective area is 1 square meter), and 500mL of tap water is added in the concentration chamber; at 10mA / cm 2 Electrodialysis treatment was carried out for 40 minutes under the condition of constant current density and flow rate of 6 L / min.

[0021] After testing, the conductivity of the tobacco extract in the desalination chamber decreased from the initial 14.61 mS / cm to 7.92 mS / cm after the treatment.

[0022] Install 10 pairs of common ion exchange membranes (the anion exchange membrane is a homogeneous anion exchange membrane CJA-2, and the cation exchange me...

Embodiment 2

[0028] Tobacco extract was prepared from tobacco stems, and 500mL of tobacco extract with a solid content of 8% was installed with 10 pairs of ion-exchange membranes (wherein the negative membrane was Selemion TM Monovalent anion selectively permeates the membrane; the cation exchange membrane is CJC-2 homogeneous cation exchange membrane, manufactured by Hefei Kejia Polymer Material Technology Co., Ltd.) in the desalination chamber of the electrodialyzer; L of sodium sulfate as the starting electrolyte; at 12mA / cm 2 Electrodialysis treatment was carried out for 58min under the condition of constant current density. After testing, the conductivity of the tobacco extract in the desalination chamber decreased from the initial 16.7mS / cm to 6.9mS / cm after treatment.

[0029] Install 10 pairs of common ion exchange membranes (the anion exchange membrane is a homogeneous anion exchange membrane CJA-2, and the cation exchange membrane is a homogeneous cation exchange membrane CJC-2,...

Abstract

The invention discloses a method for selectively reducing Zn content in the extract of reconstituted tobacco leaves by the papermaking method, which is characterized in that the tobacco extract prepared according to the production process of the reconstituted tobacco leaves by the papermaking method is introduced into a desalination chamber of an electrodialysis device for electrodialysis During the process of reducing Zn content, the degree of Zn removal is controlled by the change of conductivity in the desalination chamber or the actual content of Zn; at the same time, the nicotine content and the total amount of organic acids in the desalination chamber are detected to investigate the selectivity of Zn removal. The invention can not only effectively reduce the Zn content in the reconstituted tobacco leaf extract, but also avoid the loss of nicotine and tobacco main organic acids, thereby ensuring the smoking quality of the reconstituted tobacco leaves to the greatest extent.

Description

technical field [0001] The invention relates to a method for selectively reducing the Zn content of reconstituted tobacco leaves by a papermaking method, and belongs to the technical field of reconstituted tobacco leaves produced by a papermaking method. Background technique [0002] In recent years, with the aggravation of the contradiction between smoking and health, the smoking safety of cigarettes has become an important research direction of tobacco science. Among the 107 harmful components of cigarette smoke reported in the United States in 1989, zinc, copper, arsenic, cadmium, chromium, lead, nickel, mercury and zinc are all listed, so reducing the Zn content in tobacco and smoke will help improve Safety of cigarette smoking. [0003] Papermaking reconstituted tobacco is a kind of reconstituted tobacco, which has the characteristics of fast burning rate, low tar release, high filling value and good processing resistance. Tobacco extract concentrate is an important l...
