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 5 L / min.

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

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 13mA / cm 2 Electrodialysis treatment was carried out for 55 min under the condition of constant current density. After testing, the conductivity of the tobacco extract in the desalination chamber decreased from the initial 16.5mS / cm to 6.1mS / cm after treatment.

Abstract

The invention discloses a method for selectively reducing the content of Ni in paper-making reconstituted tobacco extraction liquid. The method is characterized in that the tobacco extraction liquid prepared according to the paper-making reconstituted tobacco production technology is led into a dilution chamber of an electrodialysis device so that the content of Ni can be reduced through electrodialysis processing, and in the Ni content reducing process, the Ni removal degree is controlled through the change of conductivity in the dilution chamber or the actual content of Ni; meanwhile, the content of nicotine and the total amount of organic acid in the dilution chamber are detected to inspect selectivity of Ni removal. The method can effectively reduce the content of Ni in the reconstituted tobacco extraction liquid, meanwhile, lose of main organic acid of nicotine and tobacco can be avoided, and smoking quality of reconstituted tobacco is guaranteed to the largest extent.

Description

technical field [0001] The invention relates to a method for selectively reducing the Ni 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] According to the Hoffman list of harmful components in smoke, heavy metals belong to a major class of harmful substances in cigarette smoke, including arsenic, lead, cadmium, chromium, nickel, etc. During the smoking process of cigarettes, heavy metals will enter the human body along with the mainstream smoke, and accumulate in various organs of the body, thereby affecting the health of the body. Therefore, reducing the nickel (Ni) content in tobacco and smoke helps to improve the 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 r...
