The treatment process of tobacco stems mainly includes pretreatment of tobacco stems, shredding and drying, but the cut stems obtained from tobacco stems have poorer sensory quality of smoke compared with ordinary cut tobacco
[0003] Authorization number CN 101904556 B discloses a tobacco stem pretreatment process. The removed tobacco stems are placed in a saturated steam environment, and then subjected to stem pressing and stem cutting, which can increase the moisture content of the obtained tobacco stems and at the same time promote the quality of the tobacco. The non-enzymatic browning reaction of stems reduces some chemical indicators in tobacco stems, but cannot improve the smoke sensory quality of cut stems

Embodiment 1
[0020] A method for treating tobacco stems includes the following steps:
[0021] (1) Add the pretreated tobacco stems to the mixed aqueous solution of ethanol, caprylic acid glyceride and Codonopsis pilosula extract. The percentages of ethanol, caprylic acid glyceride and Codonopsis pilosula extract in the mixed aqueous solution are 20%, 0.1%, 0.3 %, azeotrope for 30min;
[0022] (2) Squeeze the azeotropic tobacco stems to a moisture content of 20%, and then squeeze the tobacco stems;
[0023] (3) Add the squeezed tobacco shreds to the lysine solution, the concentration of the lysine solution is 10%, and keep the constant temperature 40℃ and stir for 30 minutes to obtain constant temperature tobacco stems;
[0024] (4) Squeeze the constant temperature tobacco stems to a moisture content of 10%, and then perform microwave expansion to obtain expanded tobacco stems.
Embodiment 2
[0026] A method for treating tobacco stems includes the following steps:
[0027] (1) Add the pretreated tobacco stems to the mixed aqueous solution of ethanol, caprylic acid glyceride and Codonopsis pilosula extract. The percentages of ethanol, caprylic acid glyceride and Codonopsis pilosula extract in the mixed aqueous solution are 30%, 0.5%, 0.8 %, azeotrope for 60min;
[0028] Steps (2) (3) (4) are the same as in Example 1.
Embodiment 3
[0030] A method for treating tobacco stems includes the following steps:
[0031] (1) Add the pretreated tobacco stems to the mixed aqueous solution of ethanol, caprylic acid glyceride and Codonopsis pilosula extract. The percentages of ethanol, caprylic acid glyceride and Codonopsis pilosula extract in the mixed aqueous solution are 22%, 0.2%, 0.6 %, azeotrope 55min;
[0032] Steps (2) (3) (4) are the same as in Example 1.

Abstract
The invention provides a tobacco stem treating method. The tobacco stem treating method includes (1), adding pre-treated tobacco stems into a mixed water solution containing ethyl alcohol, caprylic capric triglyceride and codonopsis pilosula extract to perform 30-60 minutes of azeotropy; (2), drying the azeotropic tobacco stems until the water content reaches 20-30% to obtain the dried tobacco stems; (3), adding the dried tobacco stems into a lysine solution, and stirring the lysine solution for 30-60 minutes at the constant temperature of 40-60 DEG C to obtain the constant-temperature tobaccostems; (4), drying the constant-temperature tobacco stems until the water content reaches 10-20%, and performing microwave expansion to obtain the expanded tobacco stems. The tobacco stem treating method has the advantages that the mixed water solution containing the ethyl alcohol, the caprylic capric triglyceride and the codonopsis pilosula extract is used for azeotropy of the tobacco stems, sothat the content of harmful substances in obtained stem shred smoke can be lowered, sensory quality can be improved, and expansion effect and moisture retaining performance of stem shreds can be improved initially; the azeotropic tobacco stems are dried at a time and then stirred at the constant temperature, so that the content of the harmful substances in the obtained stem shred smoke can be further lowered.
Description
Technical field [0001] The invention relates to a tobacco treatment process, in particular to a tobacco stem treatment method. Background technique [0002] Tobacco stems are a component of tobacco leaves, accounting for about 25% of the total weight of tobacco leaves. The tar and nicotine content can be effectively reduced by shredded tobacco stems and added to cigarette products. The treatment process of tobacco stems mainly includes tobacco stem pretreatment, shredding and drying, but the stem shreds obtained from tobacco stems have poorer smoke sensory quality compared with ordinary cut tobacco. [0003] Authorization number CN 101904556 B discloses a tobacco stem pretreatment process. The decontaminated tobacco stems are placed in a saturated steam environment, and then the stems are pressed and cut, which can increase the moisture content of the tobacco stems and promote the tobacco The non-enzymatic browning reaction of the stems reduces some of the chemical indicators in t...
