Embodiment 1

[0026] Take about 25g of a certain type of reconstituted tobacco leaf product by papermaking method, grind it to below 20 mesh with a high-speed grinder (rotating speed ≥ 2600 rpm) and mix thoroughly; pass the crushed particles through a 20-mesh sieve and weigh about 5g of sample (m 0 , accurate to 0.001g) placed in a pre-dried wide-mouth conical flask; accurately weigh the mass of the wide-mouth conical flask (m 1 , accurate to 0.001g); place the Erlenmeyer flask in an oven, and dry it at 105±2°C for 1 hour; take out the Erlenmeyer flask and place it in a desiccator to cool for 15 minutes; accurately weigh the The mass of the sample conical flask after drying (m 2 , accurate to 0.001g), about 70ml of heated distilled water was put into the bottle; the Erlenmeyer flask was moved to the working table of the ultrasonic extractor, and ultrasonically extracted for 5 minutes; the Erlenmeyer flask was removed and its total mass (m 3 , accurate to 0.001g); Use a disposable straw to ...

Embodiment 2

[0037] Carry out the mensuration of hot water soluble matter by step and method shown in example 1, difference is that sample is certain tobacco chip.

[0038] The following table shows the measurement results:

[0039]

Embodiment 3

[0041] Carry out the mensuration of hot water soluble matter by step and method shown in example 1, difference is that sample is certain ash stick.

Abstract

The invention provides a rapid determination method for the content of hot water-soluble substances in paper-making reconstituted tobacco. The method comprises the following steps: grinding a tobacco raw material used for production of paper-making reconstituted tobacco, a paper-making reconstituted tobacco sheet base or a finished paper-making reconstituted tobacco product into particles, sieving the particles, weighing a sample, drying the sample with an oven, then adding water, boiling the sample and calculating hot water-soluble substances in the sample by calculating hot water-soluble substances transferred to an aqueous solution. The method is applicable to solids like the raw material, the sheet base and the finished product related to the paper-making reconstituted tobacco and has the advantages of simple operation, short determination time and accurate determination results.

Description

technical field [0001] The invention relates to the technical field of a method for measuring hot water soluble matter in reconstituted tobacco leaves by a papermaking method. Background technique [0002] Paper-making reconstituted tobacco is a reconstituted tobacco raw material manufactured by the paper-making method. The manufacturing process involves the extraction, concentration and backfilling of hot water solubles derived from tobacco raw materials. Hot water soluble content refers to the percentage of hot water soluble components in the absolute dry mass of the tested sample. Therefore, the content of hot water soluble matter is one of the key indicators for judging the production of reconstituted tobacco leaves by papermaking method involving raw materials, intermediate products and finished products. [0003] At present, the production enterprises of paper-making reconstituted tobacco generally focus on the inspection of finished paper-making reconstituted tobacco...
