Embodiment 1
[0030] (4) Shred: adjust the water content of the blank stalk to 35%, and shred it with a shredder with a width of 1.4 mm to obtain shredded blank stalk.
[0031] (5) Adding materials: Add the alcohol extract to the blank cut stem, the ratio of alcohol extract / blank cut stem is 10%, 50%, 75%, 100%, 150% respectively, adjust the water content to 12-13% to get the stem Silk.
[0032] (6) Swelling and drying of shredded stems: Use steam to dampen the shredded stems, and then dry the shredded stems to make the shredded stems more fluffy.
[0033] Example 2
[0034] (1) Pretreatment: Same as Example 1.
[0035] (2) Alcohol extraction: Multiple alcohol extractions are used.
Embodiment 2
[0037] The first alcohol extraction: 4.6 kg of extract solution A was released after heating and reflux extraction for 3 hours.
[0038] The second alcohol extraction: Add 4.6kg of 75% ethanol, heat to reflux for 1h, release 4.5kg of extract B.
[0039] The third alcohol extraction: Add 4.5kg of 75% ethanol, heat to reflux for 1h, release 4.5kg of extract C
[0040] The fourth alcohol extraction: Add 4.5kg of 75% ethanol, heat and reflux for 1h, release 4.5kg of extract D
[0041] The fifth alcohol extraction: add 4.5kg of 75% ethanol, heat to reflux for 1h, release 4.5kg of extract E
[0042] The extracts A-E were concentrated respectively, and the dry weights of the ethanol extracts were measured. The dry weights of the ethanol extracts of A~E were 200g, 70g, 35g, 15g, and 7g, respectively.
[0043] Sensory evaluation was carried out on A-E alcohol extracts respectively, and the evaluation results showed that A, B, and C had better sensory quality, while D, E had slightly ...
Embodiment 3
[0048] (4) Shred: adjust the water content of the blank stalk to 35%, and shred it with a shredder with a width of 1.4 mm to obtain shredded blank stalk.
[0049] (5) Feeding: Add the alcohol extract to the blank cut stems, the alcohol extract / blank cut stems are 25%, 50%, 75%, 100%, and 150% respectively, and adjust the water content to 12-13% to obtain cut stems.
[0050] Example 4
[0051] Sensory evaluation
[0052] Sample A: adjust the water content of the stalk slices prepared in the pretreatment step (1) of Example 3 to 35%, and adjust the water content to 12-13% after shredding to obtain the control cut stalk A.

Abstract
The invention belongs to the field of tobacco processing, in particular to a processing method for improving cut stem quality. The processing method for improving the cut stem quality is characterized in that tobacco stems and stem pieces are extracted by using an alcoholic solution, and then the alcoholic solution is added back into the produced cut stems made from the tobacco stems or the stem pieces. Compared with the prior art, the processing method for improving the cut stem quality has the advantages that substances with active functions on tobacco smoking smell such as sugar, nicotine, pigment ingredients and the like of the tobacco stems are extracted by using the alcoholic solution and are added back into the cut stems later, compounds harmful to the tobacco smoking smell such as macromolecules (like pectin, protein and the like) in the tobacco stems are removed by combining water washing with acidolysis and enzymolysis, and therefore improvement of sensory quality of the cut stems is achieved, and smoke panel tests demonstrate that the cut stems prepared have the advantages that the offensive odors are reduced, the irritation is lowered, and the flavor remaining smell is improved.
Description
Technical field: [0001] The invention belongs to the field of tobacco processing, and in particular relates to a processing method for improving the quality of cut stems. Background technique: [0002] Shredded stems are thin filaments of a certain width made from tobacco stems through a series of processes such as shredding and expansion. It has the characteristics of low tar release, good filling performance, and low cost. Studies have shown that the chemical composition of cut stems is quite different from that of cut leaves, and these differences will affect the smoking quality of cigarettes. For example, the content of polyphenols, pigments and other aroma components in shredded stems is low, while the content of cellulose, lignin, pectin and other components is high. The finished shredded stems have shortcomings such as strong sensory stimulation and obvious miscellaneous gas, which can only be covered up by adding ingredients, but the effect is limited. [0003] I...
