Embodiment 1

[0017] The method for regulating the nicotine content in tobacco extraction or extract is characterized in that: 20.00 kg of tobacco raw material extraction or extract in the production of reconstituted tobacco leaves by papermaking method is taken, wherein the nicotine content is 1.60%, and the solid content is 65.2%; It is dissolved in 70.00kg of water and stirred evenly, and diluted to a concentration of about 14.5%; the diluted solution is put into an ultrafiltration membrane circulation device for circulating filtration, and the operating temperature is controlled at ≤40°C, and the operating pressure is controlled at ≤23Mpa; Obtain the retentate 43.29kg (concentration is 15.3%) of the low nicotine content that is intercepted by the ultrafiltration membrane and the dialysate 45.8kg (concentration is 13.6%) of the high nicotine content that passes through the ultrafiltration membrane, obtain after the retentate concentration Extract 9.64Kg, wherein the solid content is 68.8%...

Embodiment 2

[0020] The method for regulating the nicotine content in tobacco extraction or extract is characterized in that: 10.00 kg of tobacco raw material extraction or extract in the production of reconstituted tobacco leaves by papermaking method is taken, wherein the nicotine content is 8.73%, and the solid content is 69.6%; It is dissolved in 90.00kg of water and stirred evenly, and diluted to a concentration of about 7.0%; the diluted solution is put into an ultrafiltration membrane circulation device for circulating filtration, the operating temperature is controlled at ≤40°C, and the operating pressure is controlled at ≤25Mpa; Obtain the retentate 32.96kg (concentration is 15.7%) of the low nicotine content that is intercepted by the ultrafiltration membrane and the dialysate 66.54kg (concentration is 2.7%) of the high nicotine content that passes through the ultrafiltration membrane, obtain after the retentate concentration Extract 7.52Kg, wherein the solid content is 69.0%, the...

Embodiment 3

[0023] The method for regulating the nicotine content in tobacco extraction or extract is characterized in that: 10.00kg of tobacco raw material extraction or extract in the production of reconstituted tobacco leaves by papermaking method is taken, wherein the nicotine content is 4.33%, and the solid content is 67.2%; It is dissolved in 40.00kg of water and stirred evenly, diluted to a concentration of about 12.4%; the diluted solution is put into an ultrafiltration membrane circulation device for circulating filtration, the operating temperature is controlled at ≤40°C, and the operating pressure is controlled at ≤25Mpa; Obtain the retentate 17.37kg (concentration is 24.8%) of the low nicotine content that is intercepted by the ultrafiltration membrane and the dialysate 31.47kg (concentration is 5.7%) of the high nicotine content that passes through the ultrafiltration membrane, obtain after the retentate concentration Extract 5.49Kg, wherein the solid content is 79.1%, and the...

Abstract

The invention relates to a method for adjusting and controlling the content of nicotine in a tobacco extract. The invention aims at solving the problems of complicated technique, relatively high cost, easily damaged original aromatic components in tobacco and chemical agent residue in the extract in adjusting and controlling the content of the nicotine in the tobacco extract during the production of reconstituted tobacco leaves in the existing paper-process. The technical keys are as follows: the method is characterized in that a tobacco raw material extract used in the production of the reconstituted tobacco leaves in the paper-process is selected, a solvent is used for diluting the extract to a set concentration, the diluent obtained is put into an ultrafiltration membrane circulating device for circulation and filtration to obtain a trapped liquid which is low in nicotine content and trapped by a ultrafiltration membrane and a dialyzate which is high in nicotine content and permeates the ultrafiltration membrane, wherein, the trapped liquid is used as a material which is coated on and refilled into a substrate during the production of the reconstituted tobacco leaves in the paper-process and the dialyzate is used as a material with special usage.

Description

technical field [0001] The invention relates to a process for changing the nicotine content in tobacco, in particular to a method for regulating and controlling the nicotine content in tobacco extract by using ultrafiltration membrane separation technology. It is suitable for the production of reconstituted tobacco leaves by papermaking method. Background technique [0002] Natural tobacco leaves generally contain 1-3% nicotine. Nicotine is commonly known as nicotine. Adequate intake can stimulate the spirit, eliminate fatigue, increase thinking ability, improve work efficiency, and has a certain anesthetic effect. This is the reason why many smokers smoke. However, nicotine has certain toxicity, and excessive intake will damage human health, such as chronic pharyngitis, respiratory diseases, cardiovascular diseases, certain digestive tract diseases, headaches, insomnia and other nervous system disorders. In the current reality that it is impossible to completely quit smok...
