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. 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 improves the ...
