[0021] Enrichment method of spicy components of C3F extract from flue-cured tobacco leaves in Henan

[0022] The Henan flue-cured tobacco C3F tobacco leaves are dried in an oven, and then pulverized into tobacco powder with a pulverizer. Add 100g of tobacco powder weighed into a 1L round bottom flask, add 600mL of 75% ethanol, reflux for 4h, cool to room temperature, filter, and concentrate the filtrate on a rotary evaporator with a pressure of 50mbar and a water bath temperature of 40°C to obtain tobacco leaf extract . Weigh 15.0 g of Henan flue-cured tobacco leaf C3F extract, dissolve it in 30.0 ml of distilled water, and filter. Then, load a sample to gel chromatography, sample loading 10 milliliters, take distilled water as mobile phase, every 20 mL fractions are collected, after tasting, find that N6, N7, N8, N13, N14 fractions contain spicy components. Fractions containing spicy components were combined, enriched, and freeze-dried with a lyophilizer. Dissolve the enri...

[0024] Enrichment method of spicy components in B2F extract of Henan flue-cured tobacco leaves

[0025] The B2F tobacco leaves of Henan flue-cured tobacco were dried in an oven, and then pulverized into tobacco powder with a pulverizer. Add 100g of tobacco powder weighed into a 1L round bottom flask, add 600mL of absolute ethanol, reflux for 4 hours, filter, and concentrate the filtrate on a rotary evaporator with a pressure of 50mbar and a water bath temperature of 40°C to obtain tobacco leaf extract. Weigh 3.0 g of Henan flue-cured tobacco leaf B2F extract, dissolve it in 6.0 ml of distilled water, and filter. Then, load a sample to gel chromatography, with a sample volume of 6 milliliters, using distilled water as the mobile phase, and collect fractions every 20 mL. After tasting, it is found that the N20, N22, N23, and N24 fractions contain spicy components. Fractions containing spicy components were combined, enriched, and freeze-dried with a lyophilizer. Take 2% of the...

[0027] Enrichment Method of Pungent Components of Henan Flue-cured Tobacco Leaf X2F Extract

[0028] The Henan flue-cured tobacco X2F tobacco leaves were dried in an oven, and then pulverized into tobacco powder with a pulverizer. Add 130g of tobacco powder weighed into a 1L round bottom flask, add 700mL of ethyl acetate, reflux for 4h, filter, and concentrate the filtrate on a rotary evaporator with a pressure of 50mbar and a water bath temperature of 40°C to obtain tobacco leaf extract. Weigh 18.9 grams of Henan flue-cured tobacco leaf X2F extract, dissolve in 32.0 milliliters of distilled water, and filter. Then, load a sample to gel chromatography, with a sample volume of 9 milliliters, using distilled water as the mobile phase, and collect fractions every 20 mL. After tasting, it is found that fractions N12, 13, N16, and N17 contain spicy components. Fractions containing spicy components were combined, enriched, and freeze-dried with a lyophilizer. Take 1.5% of the enri...

Abstract

A method for enriching spicy components suitable for preparing e-cigarette liquid is characterized in that the specific steps are as follows: 1. extracting tobacco leaves with a solvent to obtain tobacco leaf extract; 2. weighing the tobacco leaf extract, centrifugally filtering, passing Column chromatographic separation, collect each fraction according to the volume of the eluent, and mark them as N1, N2, ..., etc.; 3. After the taste of each fraction is unanimously recognized by more than three professional tasters, use a freeze dryer Freeze-drying is used for the enrichment of spicy components; 4. Adding propylene glycol or glycerin to the enriched spicy components can be formulated into electronic cigarette liquid. Guided by sensory evaluation, the present invention uses column chromatography to separate the tobacco leaf extract, collects fractions of different quantities, tastes them, and uses a lyophilizer to freeze-dry the spicy fractions for enrichment. The invention has the following advantages: simple process, convenient operation, wide application range, and the obtained spicy component comes from the tobacco leaf itself, and the prepared electronic cigarette liquid has more tobacco flavor and can better meet the sensory requirements of smokers.

Description

technical field [0001] The invention belongs to the technical field of separation of tobacco products, in particular to a method for enriching spicy components suitable for preparing e-cigarette liquid. Background technique [0002] Sensory omics (sensomics) is a concept proposed by researchers by combining separation technology and sensory evaluation technology in order to find the characteristic components that trigger food taste (Angew. Chem. Int. Ed., 2011, 50, 2220-2242). At present, the most researched methods of sensory-omics are the olfactory components in natural products that trigger or regulate aroma and the taste components of sweetness, umami, bitterness, and sourness, which are widely used in food analysis. However, this method Application in tobacco leaf analysis has not been reported yet. For tobacco leaves, the impact of spiciness on sensory quality is very important. At present, a lot of research has been done on aroma components in tobacco leaves at home...
