Embodiment 1
[0023] A method for preparing a sweet-flavored incense thread with the characteristic of tobacco aroma, comprising the following steps:
[0024] (1) Spread flue-cured tobacco shreds evenly in an oven, and bake them at 50°C for 3 hours;
[0025] (2) Weigh 200 g of the cured flue-cured tobacco shreds in step (1) into a 1000 mL round bottom flask, add 200 mL of 70% ethanol to the round bottom flask, heat with an electric heating mantle until the extractant slightly boils, and reflux After extraction for 3 hours, suction filtration was performed after reflux, and the filtrate was collected, and concentrated under reduced pressure with a rotary evaporator to remove the solvent (the heating temperature of the rotary evaporator was 60°C) to obtain tobacco extract;
[0026] (3) Weigh 160 g of tobacco extract from step (2) into a 1000 mL conical flask, add 800 mL of ethanol with a concentration of 70% to the conical flask, put the conical flask into a water bath, and stir at 60°C for 1...
Embodiment 2
[0034] A method for preparing a sweet-flavored incense thread with the characteristic of tobacco aroma, comprising the following steps:
[0035] (1) Evenly spread shredded Burley tobacco in an oven and bake at 60°C for 4 h;
[0036] (2) Weigh 200 g of the cured flue-cured tobacco shreds in step (1) into a 1000 mL round bottom flask, add 400 mL of 80% ethanol to the round bottom flask, heat the extractant with a heating mantle until the extractant slightly boils, and reflux After extraction for 4 h, suction filtration was performed after reflux, the filtrate was collected, and the solvent was concentrated under reduced pressure with a rotary evaporator (the heating temperature of the rotary evaporator was 60°C) to obtain tobacco extract;
[0037] (3) Weigh 160 g of tobacco extract from step (2) into a 1000 mL conical flask, add 800 mL of ethanol with a concentration of 80% into the conical flask, put the conical flask into a water bath, and stir at 60°C for 1 h. Immediately af...
Embodiment 3
[0042] A method for preparing a sweet-flavored incense thread with the characteristic of tobacco aroma, comprising the following steps:
[0043] (1) Evenly spread shredded Burley tobacco in an oven and bake at 70°C for 5 h;
[0044] (2) Weigh 200 g of the cured oriental tobacco shreds in step (1) into a 1000 mL round bottom flask, add 600 mL of ethanol with a concentration of 90% to the round bottom flask, and heat the extractant with a heating mantle until the extractant boils slightly. Reflux extraction for 5 h. After the reflux, carry out suction filtration, collect the filtrate, and use a rotary evaporator to concentrate under reduced pressure to remove the solvent (the heating temperature of the rotary evaporator is 60°C) to obtain tobacco extract;
[0045] (3) Weigh 160 g of tobacco extract from step (2) into a 1000 mL conical flask, add 800 mL of 90% ethanol into the conical flask, put the conical flask into a water bath, and stir at 60°C for 1 h. Immediately after th...
