Embodiment 1

[0015] In a 250ml three-necked bottle, add 10ml of tobacco stem extract, add 10mmol of glucose and 10mmol of tryptophan respectively, add an appropriate amount of ammonia water to adjust the pH of the system to 7, add 90ml of propylene glycol, stir and condense at reflux at 130°C After reacting for 1.5 hours, it was cooled for later use.

[0016] The obtained modified tobacco stem solution and the unmodified tobacco stem solution are coated on the base sheet of reconstituted tobacco leaves by the papermaking method according to the same coating rate. Put the reconstituted tobacco leaf samples coated with the above two stem liquids into an oven and bake them at 40°C for half an hour. It was found that the paper-making reconstituted tobacco leaves coated with the modified tobacco stem liquids still maintained good toughness and were not brittle, while the original ones were obviously The dry toughness becomes poor and brittle, which shows that the modified tobacco stem liquid im...

Embodiment 2

[0018] In a 250ml three-neck bottle, add 10ml of tobacco stem extract, add 5mmol of glucose and 4mmol of leucine respectively, add an appropriate amount of ammonia water to adjust the pH of the system to 6.5, and then add 100ml of 1,3-butanediol , 130 ° C stirring condensation reflux reaction for 1.5 hours, cooling stand-by.

[0019] The obtained modified tobacco stem solution and the unmodified tobacco stem solution are coated on the base sheet of reconstituted tobacco leaves by the papermaking method according to the same coating rate. Put the reconstituted tobacco leaf samples coated with the above two stem liquids into an oven and bake them at 40°C for half an hour. It was found that the paper-making reconstituted tobacco leaves coated with the modified tobacco stem liquids still maintained good toughness and were not brittle, while the original ones were obviously Drying, toughness becomes poor and brittle, which shows that the modified tobacco stem liquid improves the mo...

Embodiment 3

[0021] In a 250ml three-neck bottle, add 10ml of tobacco stem extract, add 3.33mmol of glucose and 2.22mmol of lysine respectively, add an appropriate amount of ammonia water to adjust the pH of the system to 6, add 90ml of propylene glycol, and stir at 130°C After condensing and refluxing for 1.5 hours, it was cooled for use.

[0022] The obtained modified tobacco stem solution and the unmodified tobacco stem solution are coated on the base sheet of reconstituted tobacco leaves by the papermaking method according to the same coating rate. Put the reconstituted tobacco leaf samples coated with the above two stem liquids into an oven and bake them at 40°C for half an hour.

Abstract

The invention provides a method for improving the moisture retaining performance of paper-making reconstituted tobaccos with modified tobacco stem extract. The method comprises the following steps: adding ammonium hydroxide into tobacco stem extract to adjust the pH value of the system; adding sugar, amino acid and polyhydric alcohols, uniformly stirring and mixing, heating to a certain temperature, reacting for 1.5 hours, and cooling for later use; and adding the mixed liquid obtained in reaction into the paper-making reconstituted tobaccos as a coating solution, and keeping the reacting temperature at 130 DEG C. The method adopts the chemically modified tobacco stem extract to improve the chemical composition of the tobacco stem extract for the first time, so that the moisture retaining performance of the paper-making reconstituted tobaccos can be remarkably improved; and the reacting temperature is critical to the reaction, varieties and proportions of the reacting product obtained at over low or over high temperature are entirely different, and the quality and moisture retaining performance of flakes can be improved by the reaction product, namely modified tobacco stem liquid only when a proper reacting temperature is selected. The method is easy and feasible to operate, has the advantages of wide raw material source and low cost, and can remarkably improve the quality of paper-making reconstituted tobaccos.

Description

technical field [0001] The invention belongs to the technical field of papermaking reconstituted tobacco production, and in particular relates to a method for improving the moisture retention performance of papermaking reconstituted tobacco with modified tobacco stem extract. Background technique [0002] Papermaking reconstituted tobacco leaves are one of the important tobacco raw materials, which can alleviate the shortage of tobacco resources to a certain extent. Its raw materials mainly include tobacco stems, chips, tobacco powder and so on. In the production of reconstituted tobacco leaves, the tobacco stems mainly provide fibers and part of the base material for coating, but at the same time, a large amount of tobacco stem extracts are also produced. The extracts are of low use value due to the small number and content of aroma components. , or even deprecated. Due to the low content of waxy components on the surface of the tobacco stem and the large porous structure...
