Problems solved by technology

[0002] Shredded tobacco stems account for about 20%-30% of the total weight of tobacco. However, due to the disadvantages of weak fragrance, poor aftertaste, heavy woody gas, and strong irritation when burning and smoking tobacco stems, cut stems account for about 20%-30% of the total weight of tobacco. The ratio has always been low, and it is mostly found in lower-grade cigarette formulations

Embodiment 1

[0017] 1. Weigh 100 g of crushed cut tobacco stems into a 1000 ml round bottom flask, add 500 ml of cyclohexane, place in a water bath at 90° C. for reflux extraction for 2 hours. Filter the extract while hot into another 1000ml round bottom flask, add 500ml cyclohexane again, and repeat the extraction twice. Filter and transfer the filter residue to another 1000ml round bottom flask for later use.

[0018] The extracted filtrate was concentrated on a rotary evaporator with a vacuum degree of 200mbar and a water bath temperature of 50°C to free of cyclohexane, and then concentrated under reduced pressure to 100mbar until solvent-free dripping to obtain crude extract A1.

[0019] 2. Add 500ml of ethyl acetate to the 1000ml round-bottomed flask that the filter residue was transferred to, and then reflux and extract for 2 hours at a water bath temperature of 80°C, and then use 1000ml of ethyl acetate to repeat the extraction twice. 200mbar, concentrated on a rotary evaporator ...

Embodiment 2

[0025] 1. Weigh 100g of crushed low-grade tobacco leaves into a 2000ml round bottom flask, add 1500ml of petroleum ether with a boiling range of 30-60, and place it in a 50°C water bath for reflux extraction for 2 hours. Filter the extract while hot into another 2000ml round bottom flask, add 1500ml petroleum ether again, and repeat the extraction twice. Filter and transfer the filter residue to another 2000ml round bottom flask for later use.

[0026] The extracted filtrate was concentrated on a rotary evaporator with a vacuum degree of 700mbar and a water bath temperature of 50°C until there was no petroleum ether, and then concentrated under reduced pressure to 200mbar until solvent-free and dripped to obtain crude extract A2.

[0027] 2. Add 600ml of acetone to the 1000ml round-bottomed flask into which the filter residue was transferred, reflux and extract at 60°C water bath temperature for 2 hours, then use 1200ml acetone to repeat the extraction twice, after merging, ...

Embodiment 3

[0033] 1. Weigh 50 g of crushed fenugreek seeds and 50 g of crushed shredded leaves in a 2000 ml round bottom flask. Add 1000ml of petroleum ether with a boiling range of 30-60, reflux and extract at 60°C water bath temperature for 2 hours, filter the extract while it is hot into another 2000ml round bottom flask, add 1000ml of petroleum ether again, and repeat the extraction twice. Filter and transfer the filter residue to another 2000ml round bottom flask for later use.

[0034] After combining, concentrate on a rotary evaporator with a vacuum degree of 700mbar and a water bath temperature of 50°C, and then reduce the pressure to 200mbar and concentrate to dryness to obtain crude extract A3.

[0035] 2. Add 800ml of diethyl ether to the 1000ml round-bottomed flask into which the filter residue was transferred, reflux and extract at 40°C water bath temperature for 2 hours, then use 1600ml diethyl ether to repeat the extraction twice, after combining, place on a rotary evapor...

Abstract

The invention discloses a preparation method of a tobacco sauce additive capable of improving the smoking quality of cut tobacco stems. The preparation method is characterized in that one or more of the cut tobacco stems, low-grade cut tobaccos or other natural products are taken as raw materials, the raw materials are sequentially extracted by low-polarity, medium-polarity and high-polarity solvents, and extract is dissolved in ethyl alcohol, propylene glycol or a mixture of ethyl alcohol and propylene glycol to prepare the tobacco sauce additive. The tobacco sauce additive is sprayed in the cut tobacco stems, the special wood gas of the cut tobacco stems can be reduced remarkably, the irritation is reduced, and smoking aftertaste quality of the cut tobacco stems and comfort are improved.

Description

technical field [0001] The invention belongs to the technical field of cigarette material liquid preparation, and in particular relates to a preparation method and application of a tobacco material liquid additive capable of improving the burning and smoking quality of cut tobacco stems. , obtained through extraction and multi-step processing, after adding to cut stems, the test results show that the liquid can significantly reduce the unique woodiness of cut stems, reduce irritation, and greatly improve the aftertaste and comfort of cut stems after smoking. Background technique [0002] Shredded tobacco stems account for about 20%-30% of the total weight of tobacco. However, due to the disadvantages of weak fragrance, poor aftertaste, heavy woody gas, and strong irritation when burning and smoking tobacco stems, cut stems account for about 20%-30% of the total weight of tobacco. The proportion has always been low, and it is mostly found in lower-grade cigarette formulas. T...
