Problems solved by technology

[0002] my country is a big tobacco producing country. In tobacco agricultural production, a large number of tobacco stalks are discarded every year. After the tobacco leaves are harvested, farmers directly discard the tobacco stalks in the field or field, which not only causes field traffic, irrigation blockage, breeding and spreading of diseases and insect pests, And its leaching solution will pollute the soil, if it is dried and incinerated, it will pollute the atmosphere, causing a great waste of resources

Embodiment 1

[0019] Grind the bast of the naturally dried tobacco stems into 80 meshes, add 95% (volume fraction, the same below) ethanol which is 6 times its mass, extract by reflux at 80°C for 3 hours, cool and filter, and adjust the pH with sodium hydroxide value to 7.0, add neutral protease (enzyme activity 50,000 u / g) with a mass concentration of 6.0 g / L, extract at 40°C for 4 hours, and concentrate at 80°C to obtain a crude extract. For the crude extract of the extract, use 95% ethanol which is 3 times its mass as the extractant, and the extract is obtained after distillation. The obtained extract is placed in a brown bottle and sealed and refrigerated.

[0020] Dilute the obtained extract with water to 1% (wt%, the same below), according to the ratio of adding 50g (the addition ratio of the extract is 0.05%) of the diluent to 1000g of tobacco leaves, spray it evenly into the leaves, place it at room temperature for 2h, absorb Finally, cut into shreds, dry shreds, and make cigarette...

Embodiment 2

[0022] Grind the naturally dried tobacco stem bast into 60 meshes, add 5 times its mass of 90% ethanol, reflux extraction at 70°C for 4 hours, cool and filter, adjust the pH value to 6.5 with sodium hydroxide, and add a mass concentration of 6.0g / L of neutral protease (50,000 u / g), extracted at 50°C for 5h, concentrated at 70°C to obtain a crude extract. For the crude extract of the extract, 4 times the volume fraction of 95% ethanol is used as the extractant, and the extract is obtained after distillation. The obtained extract is placed in a brown bottle and sealed and refrigerated.

[0023] Dilute the obtained extract with water to 2%, add 50g (the addition ratio of the extract is 0.10%) of diluent to 1000g of tobacco leaves, evenly spray it into the leaves, place it at room temperature for 2h, and cut it into shreds according to the normal process after absorption. Dried silk, cigarettes.

Embodiment 3

[0025] Grind the naturally dried tobacco stem bast into 70 meshes, add 6 times the volume fraction of 85% ethanol, extract at 80°C for 4 hours, cool and filter, adjust the pH value to 7.0 with sodium hydroxide, and add a mass concentration of 6.0 g / L neutral protease (50,000 u / g), extract at 55°C for 6h, and concentrate at 60°C to obtain crude extract. For the crude extract of the extract, 3 times the volume fraction of 95% ethanol is used as the extractant, and the extract is obtained after distillation. The obtained extract is placed in a brown bottle and sealed and refrigerated.

[0026] Dilute the obtained extract to 3% with ethanol with a volume fraction of 75%, and spray it evenly into the leaves according to the ratio of adding 50g (the addition ratio of the extract is 0.15%) to 1000g of tobacco leaves, and place it at room temperature for 2 hours. Shredded, dried and rolled according to the normal process.

Abstract

The invention belongs to the technical field of tobacco flavors, and particularly relates to tobacco extract, and an extraction method and application thereof. The tobacco extract is obtained from tobacco stalk bast by extracting. By the method, agricultural tobacco waste is changed into wealth, so that resources are fully utilized. Feasibility and controllability of industrial production are fully considered in the design of preparation technique roadmaps, the obtained extract is purely natural tobacco homologous perfume and has great market potential. The tobacco extract is convenient in application and convenient to obtain by existing cigarette processing technology, and smoking quality of cigarettes can be improved distinctly.

Description

technical field [0001] The invention belongs to the technical field of tobacco spices, in particular to a tobacco extract and its extraction method and application. Background technique [0002] my country is a big tobacco producing country. In tobacco agricultural production, a large number of tobacco stalks are discarded every year. After the tobacco leaves are harvested, farmers directly discard the tobacco stalks in the field or field, which not only causes field traffic, irrigation blockage, breeding and spreading of diseases and insect pests, And its leaching solution will pollute the soil, and if it is dried and incinerated, it will pollute the atmosphere, causing a great waste of resources. If these tobacco stalks can be utilized, not only can the pollution caused by them be avoided, but also more value can be created by turning waste into treasure. Contents of the invention [0003] The purpose of the present invention is to provide a tobacco extract and its extra...
