Embodiment 1

[0025] Example 1 (compared with shredded stem 1 #)

[0026] Tobacco stems are made into shredded stems by conventional methods in the art, and used as a contrast, specifically through the following processing steps:

[0027] 1) Stem washing: Tobacco stems are washed to remove floating dust, and the moisture content is adjusted to about 40% for pressing and shredding;

[0028] 2) Stem pressing and shredding: the wet tobacco stems are pressed using a stem pressing machine, and shredded by a shredding machine with a width of 1.2mm;

[0029] 3) Drying: the control shredded stems were obtained by drying with a silk dryer.

Embodiment 2

[0030] Example 2 (stem 2 #)

[0031] A method for processing shredded stems with low crotonaldehyde emission, using tobacco stems as raw materials, comprising the following steps:

[0032] 1) Water extraction: extract the tobacco stems with water at 25°C for 12 hours, and use a screen to separate the solids and liquids to obtain the extract and residual stems; the amount of water used is 10 times the weight of the tobacco stems;

[0033] 2) Fermentation of the extract: After the extract is concentrated to 1 / 10 of the original volume, add active dry yeast (Saccharomyces cerevisiae) and ferment at 40°C for 0.5h; the amount of yeast used is 0.5% of the weight of the tobacco stems,

[0034] 3) Squeeze and shred the remaining stalks: adjust the water content of the remaining stalks to about 40%, use a stalk press to press the remaining stalks into slices, and use a shredder to cut the stalks into shreds;

[0035] 4) Feed liquid back-adding: add back the fermented extract obtained ...

Embodiment 3

[0037] Example 3 (stem shredded 3 #)

[0038] A method for processing shredded stems with low crotonaldehyde emission, using tobacco stems as raw materials, comprising the following steps:

[0039] 1) Water extraction: extract the tobacco stems with water at 25°C for 12 hours, and use a screen to separate the solids and liquids to obtain the extract and residual stems; the amount of water used is 10 times the weight of the tobacco stems;

[0040] 2) Fermentation of the extract: After the extract is concentrated to 1 / 10 of the original volume, add active dry yeast (Saccharomyces cerevisiae) and ferment at 40°C for 0.5h; the amount of yeast used is 0.5% of the weight of the tobacco stems,

[0041] 3) Squeeze and shred the remaining stalks: adjust the water content of the remaining stalks to about 40%, use a stalk press to press the remaining stalks into slices, and use a shredder to cut the stalks into shreds;

[0042] 4) Adding amino acids to the extract and adding back: addin...

Abstract

The invention relates to a method for processing shredded stalks with low crotonaldehyde emission, which uses tobacco stalks as raw materials, and comprises the following steps: 1) Water extraction: extracting the tobacco stalks with water, and separating the solid and liquid to obtain the extract and Residual stems; 2) Fermentation of the extract: After the extract is concentrated, yeast is added for fermentation; 3) The residual stems are pressed and shredded: the residual stems are pressed into slices by a stem press, and cut into shreds by a shredder ; 4) Adding feed liquid back: adding back the fermented extract obtained in step 2) to the shredded stems obtained in step 3); 5) Drying: drying to obtain finished shredded stems. After the tobacco stems prepared by the processing method are made into shredded stems, the release amount of crotonaldehyde is significantly reduced, and blended into the cigarette formula can reduce the release amount of smoke crotonaldehyde.

Description

technical field [0001] The invention belongs to the technical field of tobacco processing, and in particular relates to a method for processing shredded stems with low crotonaldehyde emission, as well as its products and applications. 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. However, due to the large differences between the chemical composition of tobacco stems and shredded leaves, on the one hand, these differences lead to the shortcomings of tobacco stems such as strong sensory stimulation and obvious miscellaneous gas, and on the other hand, they cause the release of volatile carbonyl compounds such as crotonaldehyde in tobacco stems. The amount is higher than that of leaf silk, thus limiting its application. [0003] There have been some studies in recent ye...
