Embodiment 1

[0025] Preparation of additives:

[0026] (1) The preparation process route is as follows: figure 1 shown. The unsuitable lower two fresh tobacco leaves (as shown in Figure 2) were used as raw materials for the optimized structure of Yunyan 87 flue-cured tobacco variety in Kunming Tobacco Area, Yunnan.

[0027] (2) After the juice is homogenized, filter it with a plate and frame filter press at 10°C to collect the filtrate;

[0028] (3) Concentrate the filtrate with an ultrafiltration membrane at 25°C. The primary cut-off molecular weight is 100,000. After 24 hours of ultrafiltration, the concentrated solution is collected to obtain component 1; the filtrate is subjected to secondary separation, and the cut-off molecular weight is 50,000. After 24 hours of ultrafiltration, the concentrated solution is collected to obtain component 2; the filtrate is subjected to the third stage Separation, the molecular weight cut-off is 20,000, after ultrafiltration for 48 hours, the conce...

Embodiment 2

[0042] Preparation of additives:

[0043] (1) The preparation process such as figure 1 shown. The unsuitable upper two tobacco leaves (as shown in Figure 2) were used as raw materials for K326 variety K326 tobacco leaf structure optimized in the Kunming Tobacco Area of ​​Yunnan Province.

[0044] (2) After the juice is homogenized, centrifuge in a centrifuge at 15°C at a speed of 10,000 r / min for 10 minutes, and collect the centrifuged supernatant;

[0045] (3) The filtrate was concentrated by ultrafiltration membrane at 20°C. The primary cut-off molecular weight is 100,000. After 36 hours of ultrafiltration, the concentrated solution is collected to obtain component 1; the filtrate is separated by an ultrafiltration membrane with a cut-off molecular weight of 30,000. After 30 hours of ultrafiltration, the concentrated solution is collected to obtain component 2; The grade cut-off molecular weight was 10,000, and component 3 was obtained after ultrafiltration for 24 hours. ...

Embodiment 3

[0059] Preparation of additives:

[0060] (1) The preparation process such as figure 1 shown. The unsuitable upper two tobacco leaves (as shown in Figure 2) were used as raw materials for the optimized tobacco leaf structure of the red variety in the Kunming Tobacco Area of ​​Yunnan.

[0061] (2) After the juice is homogenized, centrifuge in a centrifuge at 8°C at a speed of 3000 r / min for 20 minutes, and collect the centrifuged supernatant;

[0062] (3) The filtrate was concentrated using an ultrafiltration membrane at 30°C. The primary molecular weight cut-off is 80,000. After 25 hours of ultrafiltration, the concentrated solution is collected to obtain component 1; the secondary molecular weight cut-off is 40,000. After 20 hours of ultrafiltration, the concentrated solution is collected to obtain component 2; the third-stage molecular weight cut-off is 20,000. Component 3 was obtained after ultrafiltration for 20 h.

[0063] (4) Combine components 1 and 2, let stand for...

Abstract

The invention discloses a preparing and use method for an additive capable of improving the quality of flue-cured tobacco leaves in a tobacco leaf modulation stage. The additive uses fresh tobacco leaves as a raw material and is prepared through a membrane separation method. In the tobacco leaf modulation stage, water is added in the additive, the additive is diluted into a solution with the concentration of 10-15%, the solution is added on surfaces of normal mature fresh tobacco leaves, and then the fresh tobacco leaves are dried in air, and baking is performed according to a normal three-stage baking technique. The invention further provides a development utilization method for inapplicable fresh tobacco leaves, the development utilization method uses the inapplicable fresh tobacco leaves as a raw material, and the additive capable of improving the quality of the flue-cured tobacco leaf in the tobacco leaf modulation stage is prepared through the membrane separation method. The preparing and use method can turn the inapplicable fresh tobacco leaves into a valuable material and uses the tobacco waste resource as the raw material, is rich in raw material source, and is low cost; the preparing method is easy to operate, and the prepared additive has good compatibility with the tobacco leaves. The hierarchal structure of the flue-cured tobacco leaves is remarkably improved through additive spraying, aroma substances such as organic acids and polyphenol are increased, the smoking quality is improved, and indexes such as aroma amount and offensive odor can be remarkably improved.

Description

technical field [0001] The invention relates to the technical field of tobacco additives and flue-cured tobacco modulation, in particular to the preparation of an additive for improving the quality of flue-cured tobacco in the tobacco leaf modulation process and its use in tobacco leaf curing. Background technique [0002] The content of macromolecular substances such as starch, protein, and pigment in fresh tobacco leaves is relatively high, and it needs to be baked, modulated, rebaked, and alcoholized before it can be used in cigarettes. However, due to the short time and high temperature during the baking process, some macromolecular substances are not fully degraded, so that the first-cured tobacco leaves in my country still have defects such as excessive starch content, insufficient pigment degradation, insufficient aroma, and uncoordinated chemical components. It is more common in the upper and lower leaves. [0003] It has been reported that additives are used in the ...
