Embodiment 1

[0029] Crush the tobacco leaves to 100 mesh, transfer to the subcritical extraction kettle, then add butane and 0.1% cetyl alcohol triethoxyethylene ether accounting for the mass percentage of butane, the ratio of solid to liquid is 1:8, at 10°C Extract for 3 hours, and the extraction pressure is the saturated vapor pressure of butane at a temperature of 10°C. After the extraction, the dewaxed tobacco leaves are obtained, and the extract is evaporated under reduced pressure to obtain plant wax, wherein the yield of the plant wax is 1.5%.

Embodiment 2

[0040] Crush the tobacco leaves to 100 mesh, transfer to the subcritical extraction kettle, then add butane and tetradecyl alcohol pentaethoxylate accounting for 0.5% by mass percentage of butane, the ratio of solid to liquid is 1:10, at 5°C Extract for 4 hours, the extraction pressure is the saturated vapor pressure of butane at 5°C. After the extraction, the wax-removed tobacco leaves were obtained, and the extract was evaporated under reduced pressure to obtain plant wax, with a total extraction yield of 2.12%, of which the plant wax yield was 1.73%.

Embodiment 3

[0045] Crush the tobacco leaves to 10 mesh, transfer them to a subcritical extraction kettle, then add a butane solution containing 1% dodecyl alcohol trisoxyethylene ether, the ratio of solid to liquid is 1:12, and extract at 10°C for 1.5h , the extraction pressure is the saturated vapor pressure of butane at the temperature of 10°C. After the extraction, the dewaxed tobacco leaves are obtained, and the extract is evaporated under reduced pressure to obtain plant wax, wherein the yield of plant wax is 2.6%.

[0046] Tobacco extract was prepared from the dewaxed tobacco leaves after subcritical extraction by solvent extraction, using 50% ethanol as solvent, the ratio of solid to liquid was 1:10, and extracted at room temperature for 24 hours. After the extraction is completed, the extract is filtered and separated, and the extract is concentrated under reduced pressure until there is no alcohol, and the tobacco leaf extract 1 is obtained. # (Yield 19.52%). Using undewaxed to...

Abstract

The invention relates to an additive, a wax removal solvent and a removal method for removing wax from tobacco leaves. Fatty alcohol polyoxyethylene ether compounds are used to remove wax from tobacco leaves. Affinity; at the same time, the polyoxyethylene ether group in the polyoxyethylene ether compound can increase the solvation ability of the extraction solvent and promote the dissolution of medium and low polarity waxes in plant materials. Therefore, the additive can be used for extraction Remove plant wax, effectively remove wax in tobacco leaves without affecting the content of active ingredients such as total sugar, reducing sugar, and aroma components in plant raw materials, and at the same time keep the physical form of pretreated tobacco leaves unchanged Thus, the content of the characteristic aroma components of the plant essential oil extracted on the basis of the pretreated tobacco leaves is basically not affected by the pretreatment, and at the same time, the problems of poor solubility and poor sensory quality of the tobacco extract caused by a large amount of plant wax are avoided.

Description

technical field [0001] The invention belongs to the field of preparation of tobacco essence and fragrance, and in particular relates to an additive for removing wax from tobacco leaves, a wax removal solvent and a removal method. Background technique [0002] There are a lot of waxy substances on the surface of tobacco leaves, the main components of which are various lipophilic compounds, forming a hydrophobic layer on the surface, which is one of the important components of tobacco skin. The research results showed that the waxes in tobacco leaf skin were mainly straight-chain alkanes, branched-chain alkanes, triterpenoids, fatty alcohols and so on. In the preparation process of tobacco extract, it is inevitable to extract the wax on the surface of tobacco leaves into the extract solution, and the solubility of wax in ethanol and water is low, which will affect the product quality of tobacco extract, resulting in There are problems such as suspended solids and poor solubil...
