Embodiment 1

[0055] Preparation of coating solution: Tobacco stems were pre-extracted with water at a temperature of (70±5)°C for 30 minutes at a ratio of 1:3.8, and then defibrated after solid-liquid separation; defibrated tobacco stems and tobacco sheets and The tablet powder was mixed at a ratio of 1:1:1, and extracted with water at a ratio of 1:4.2 at a temperature of (65±5)°C for 20 minutes, and the obtained extract was filtered through a 100-mesh sieve after solid-liquid separation (purification treatment) . And concentrate it to a density of 1.20-1.22g / cm 3 , the resulting concentrated solution is the coating solution.

[0056] Molecular sieve materials adsorb TSNAs in the coating solution: add molecular sieves NaZSM-5, NaY, CaA, MCM-41, and SBA-15 to a certain amount of coating solution at 0.1g / mL, and treat them with magnetic stirring in a water bath at 60°C After 30 minutes, the coating solution was centrifuged, and the obtained sample was used for detection and analysis.

Embodiment 3

[0069] Preparation of coating solution: Tobacco stems were pre-extracted with water at a temperature of (70±5)°C for 32 minutes at a ratio of 1:3.6, and then defibrated after solid-liquid separation; defibrated tobacco stems and tobacco sheets and The tablet powder is mixed in a ratio of 1:0.9:1.1, and extracted with water at a ratio of 1:4.0 at a temperature of (65±5)°C for 22 minutes. After solid-liquid separation, the obtained extract is filtered through a 100-mesh sieve (purification treatment) . And concentrate it to a density of 1.20-1.22g / cm 3 , the resulting concentrated solution is the coating solution.

[0070] Molecular sieve materials adsorb TSNAs in the coating solution: add molecular sieve MCM-41 at 0.09 g / mL to a certain amount of coating solution, and treat it with magnetic stirring in a water bath at 58°C for 35 minutes, and then centrifuge the coating solution to obtain The sample was used for detection and analysis. Compared with the sample without molecul...

Abstract

The invention relates to the field of reconstituted tobacco preparation, in particular to a method for reducing the TSNAs content in a paper-making-process reconstituted tobacco coating solution. The method for reducing the TSNAs content in the paper-making-process reconstituted tobacco coating solution comprises the following steps that 1, tobacco stems are subjected to extraction with water and is subjected to fiber separation treatment after solid-liquid separation; 2, the tobacco stem subjected to the fiber separation treatment is mixed with tobacco flakes and tobacco waste, then water is added for extraction and solid-liquid separation, the obtain extracting solution is subjected to purifying treatment; 3, a mesoporous molecular sieve is added to the treated solution obtained in the step 2 for adsorption treatment, a finished product is obtained through solid-liquid separation after treatment. The method for reducing the TSNAs content in the paper-making-process reconstituted tobacco coating solution absorbs the TSNAs in the coating solution by adopting a molecular sieve physical absorption method, has the very good effect on the reduction of the TSNAs in paper-making-process reconstituted tobaccos and is simple in process and easy to achieve, and the large change of an existing process is not needed.

Description

technical field [0001] The invention relates to the field of reconstituted tobacco leaf preparation, in particular to a method for reducing the content of TSNAs in the tobacco coating solution of reconstituted tobacco leaves by papermaking. Background technique [0002] Paper-process reconstituted tobacco (Paper-process reconstituted tobacco), also known as tobacco sheet, is a kind of "artificial tobacco leaf" made by processing tobacco by-products and waste materials using modern extraction and separation technology and improved papermaking technology, also known as papermaking. The reconstituted tobacco leaf is mainly made of tobacco pulp made from waste materials in tobacco processing such as tobacco stems, shredded tobacco pieces and tobacco powder, mixed with a certain amount of wood pulp and fillers, and then copied into a substrate by a paper machine and then dipped and coated. be made of. [0003] Paper-making reconstituted tobacco has become an important part of ci...
