Embodiment 1

[0024] Embodiment 1: the preparation of KRK26 tobacco extract

[0025] 1. Soak 50g of tobacco leaves in 95% ethanol for 2 hours, the ratio of solid to liquid is 1g: 10ml, extract in a water bath under reflux, the temperature of the water bath is 50°C, repeat the extraction twice, and then carry out vacuum distillation at 50°C to concentrate the extracted solution to brown The viscous liquid obtained 8.3 grams of extract after cooling.

[0026] 2. Dissolve the extract obtained above in water, filter it, and put it on a macroporous adsorption resin column HPD-100. The dosage is 20 times the mass of the extract. With a flow rate of 1.5BV / h, first elute 10BV with water, and then use 95% ethanol 20BV was eluted, and the eluate was collected and concentrated under reduced pressure to obtain 6.3 g of an isolate.

[0027] 3. After the isolate is dissolved and filtered with ethanol, put it on a gel chromatographic column, the filler is SephadexLH-20, the consumption is 40 times of the...

Embodiment 2

[0048] 1. Soak 50g of tobacco leaves in 95% ethanol for 2h, the ratio of solid to liquid is 1g: 8ml, extract in a water bath under reflux, the temperature of the water bath is 60°C, and repeat the extraction twice. Afterwards, the extracted solution was concentrated by distillation under reduced pressure at 50° C. to a brown viscous liquid, and 9.1 g of extract was obtained after cooling.

[0049] 2. Dissolve the above-mentioned extract in water, filter it, and put it on a macroporous adsorption resin column HPD-100. The dosage is 10 times the mass of the extract. At a flow rate of 1.5BV / h, first wash 8BV with water, and then use 90% 20BV was eluted with ethanol, and the eluate was collected and concentrated under reduced pressure to obtain 7.0 g of an isolate.

[0050] 3. After the isolate is dissolved and filtered with ethanol, put it on a gel chromatography column, the filler is SephadexLH-20, the dosage is 30 times of the quality of the isolate, the mobile phase is absolut...

Embodiment 3

[0055] 1. Soak 50g of tobacco leaves in 95% ethanol for 1h, the ratio of solid to liquid is 1g:20ml, extract in a water bath under reflux, the temperature of the water bath is 70°C, repeat the extraction twice, and then carry out vacuum distillation at 50°C to concentrate the extracted solution to brown The viscous liquid obtained 9.8 grams of extract after cooling.

[0056] 2. Dissolve the above-mentioned extract in water, filter it, and put it on a macroporous adsorption resin column HPD-100. The dosage is 15 times the mass of the extract, and at a flow rate of 1.5BV / h, first elute 8 BV with water, and then use 15 BVs were eluted with 95% ethanol, and the eluate was collected and concentrated under reduced pressure to obtain 7.4 g of an isolate.

[0057] 3. After concentrating under reduced pressure to obtain the isolate, dissolve and filter it with ethanol, put it on a gel chromatographic column (SephadexLH-20, the consumption is 50 times the quality of the isolate), the mo...

Abstract

The invention discloses a KRK26 tobacco extract. The KRK26 tobacco extract contains maltol, vanillic acid and 5-hydroxymethylfurfural, and the KRK26 tobacco extract has a strawberry-like note. The invention further discloses a preparation method and application of the KRK26 tobacco extract.

Description

technical field [0001] The invention belongs to the field of tobacco, and in particular relates to a KRK26 tobacco extract, its preparation method and application. Background technique [0002] Tobacco fragrance highlights the characteristics of tobacco leaves, and reflects the characteristics of flue-cured tobacco flavor and aroma style. As a natural flavor of tobacco, tobacco aroma substances are the most ideal flavor enhancers, which can be added to cigarettes, cigarette paper, filter materials and Plasticizers are used to increase the aroma of cigarettes, improve the sensory quality of cigarettes and the aroma of tobacco, and increase satisfaction. At the same time, it can improve the comprehensive utilization rate of tobacco raw materials and reduce costs. It has a relatively broad market and application prospects. KRK26 is Zimbabwe's main flue-cured tobacco variety, and it is also one of the six imported flue-cured tobacco varieties approved by the National Variety Com...
