Embodiment 1

[0024] Example 1 (stem 1 #)

[0025] A processing method for reducing the release of crotonaldehyde from shredded stems, using shredded stems as a raw material, comprising the following steps:

[0026] 1) Extraction of cut stems: extract cut stems with water at 25°C for 0.5 hours, and use a sieve to separate solids and liquids to obtain the extract and residual cut stems; the amount of water used is 10 times the weight of cut stems;

[0027] 2) Fermentation of the extract: After the extract is concentrated to 1 / 4 of the original volume, add active dry yeast (Saccharomyces cerevisiae) and ferment at 40°C for 0.5h;

[0028] 3) Adding back the extract: add back the fermented extract obtained in step 2) to the residual shredded stems obtained in step 1);

[0029] 4) Drying: Dried to obtain finished shredded stems.

Embodiment 2

[0030] Example 2 (stem 2 #)

[0031] A processing method for reducing the release of crotonaldehyde from shredded stems, using shredded stems as a raw material, comprising the following steps:

[0032] 1) Extraction of cut stems: extract cut stems with water at 25°C for 0.5 hours, and use a sieve to separate solids and liquids to obtain the extract and residual cut stems; the amount of water used is 10 times the weight of cut stems;

[0033] 2) Fermentation of the extract: After the extract is concentrated to 1 / 4 of the original volume, add active dry yeast (Saccharomyces cerevisiae) and ferment at 40°C for 0.5h;

[0034] 3) Adding amino acids to the extract and adding back: adding proline to the fermented extract obtained in step 2), and then adding back to the residual shredded stems obtained in step 1); the amount of proline added is 1 / 2 of the weight of shredded stems 3.0%;

[0035] 4) Drying: Dried to obtain finished shredded stems.

Embodiment 3

[0036] Example 3 (stem shredded 3 #)

[0037] A processing method for reducing the release of crotonaldehyde from shredded stems, using shredded stems as a raw material, comprising the following steps:

[0038] 1) Extraction of cut stems: extract cut stems with water at 25°C for 0.5 hours, and use a sieve to separate solids and liquids to obtain the extract and residual cut stems; the amount of water used is 10 times the weight of cut stems;

[0039] 2) Fermentation of the extract: After the extract is concentrated to 1 / 4 of the original volume, add active dry yeast (Saccharomyces cerevisiae) and ferment at 25°C for 12 hours; the amount of yeast used is 0.2% of the weight of the cut stems,

[0040] 3) Adding amino acids to the extract and adding back: adding valine to the fermented extract obtained in step 2), and then adding back to the residual cut stems obtained in step 1); the amount of valine added is 1 / 2 of the weight of the cut stems 0.5%;

[0041] 4) Drying: Dried to...

Abstract

The invention relates to a processing method for reducing the release of crotonaldehyde from shredded stems, which uses shredded stems as a raw material, and comprises the following steps: 1) Extracting shredded stems: extracting shredded stems with water, and separating the solid and liquid to obtain the extract and residual Shredded stems; 2) Fermentation of the extract: after the extract is concentrated, yeast is added for fermentation; 3) Addition of the extract: the fermented extract obtained in step 2) is added back to the remaining shredded stems obtained in step 1); 4) Drying: drying to obtain finished shredded stems. The crotonaldehyde release amount of cut stems prepared by the treatment method is obviously reduced, and the crotonaldehyde release amount of smoke can be reduced when blended into cigarette formula.

Description

technical field [0001] The invention belongs to the technical field of tobacco processing, and in particular relates to a processing method for reducing the release of crotonaldehyde from shredded stems, as well as its product and application. 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, since the chemical composition of cut stems is quite different from that of shredded leaves, on the one hand, these differences cause the cut stems to have shortcomings such as strong sensory stimulation and obvious miscellaneous gas, and on the other hand, cause the release of volatile carbonyls such as crotonaldehyde from cut stems. The amount is higher than that of leaf silk, thus limiting its application. [0003] There have been some studies in recent years on improvin...
