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 processing method for low-crotonaldehyde-release cut stems. The tobacco stems are used as raw materials. The processing method comprises the following steps of 1) water extraction: the water is used to extract the tobacco stems, after finishing extracting, the extracting solution and the remaining stems are obtained through solid-liquid separation; 2) extraction solution fermentation: after the extracting solution is concentrated, the yeast is added to perform fermentation treatment; 3) rolling and cutting for the remaining stems: a stem rolling machine is used to roll the remaining stems into the rolled stems, and then the tobacco cutting machine is used to cut the rolled stems into cut stems; 4) returning material: returning the extracting solution after being fermented and treated into the cut stems obtained from step 3); and 5) dehydration: the product cut stems is acquired through dehydration. After the preparation of the processing method, the tobacco stems are made into cut stems, the burst size of crotonaldehyde is significantly reduced. When the cut stems are blended into the formula of cigarettes, the burst size of crotonaldehyde can be decreased.

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...
