Enrichment method of peppery component suitable for preparing electronic cigarette liquid

Abstract

The invention relates to an enrichment method of a peppery component suitable for preparing an electronic cigarette liquid. The enrichment method is characterized by comprising the following steps: (1) extracting a tobacco leaf extract from tobacco leaves by virtue of a solvent; (2) weighing the tobacco leaf extract, carrying out centrifugal filtration and column chromatography separation, collecting each fraction according to the volume of eluent, and respectively marking the fractions as N1, N2,......, etc.; (3) after the fractions are tasted by at least three professional evaluation persons and the peppery fraction is determined, freeze-drying the peppery fraction by virtue of a freeze-drying machine, and enriching the peppery fraction; and (4) adding the enriched peppery fraction into propylene glycol or glycerinum, so as to prepare the electronic cigarette liquid. The enrichment method is guided through sensory evaluation, the tobacco leaf extract is separated by virtue of column chromatography, different numbers of the fractions are collected and are tasted, and the peppery fraction is freeze-dried by virtue of the freeze-drying machine and is enriched. The enrichment method has the advantages that the flow is simple, the operation is convenient, and the application range is wide; and furthermore, the obtained peppery component is derived from the tobacco leaves, so that the prepared electronic cigarette liquid has strong tobacco fragrance and can meet 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 in order to find the characteristic components that trigger food taste by combining separation technology and sensory evaluation technology (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...

Problems solved by technology

[0003] E-cigarettes use e-cigarette liquid to heat through an electronic atomizer to produce a cigarette-like mist, mainly using a mixture of tobacco-specific flavors and glycerol or propylene glycol as e-cigarette liquid, but currently e-cigarettes that use e-cigarette liquid and Consumers have always been dissatisfied with the sensory evaluation of traditional smoking cigarettes.
