Abstract
The invention relates to an electronic cigarette, and discloses a supercritical extraction method for tobacco essential oil. The method comprises the following steps: weighing a certain amount of tobacco powder to put into an extraction kettle; charging CO2 from the bottom of the extraction kettle as extracting fluid, wherein the circulation volume is 2-5 times of weight of the tobacco powder in the extraction kettle; the extraction pressure inside the extraction kettle is 250-300bar; the temperature is 40-60 DEG C; firstly, carrying out static extraction; adding absolute ethyl alcohol according to 5-8% of weight of the tobacco powder; carrying out static extraction for 30 minutes, and then dynamically extracting for 1-3 hours, so as to obtain the product, namely tobacco essential oil from a separation kettle. The invention also discloses electronic cigarette atomized liquid prepared by using the method. The electronic cigarette atomized liquid disclosed by the invention has the advantage that volatile aroma components (tobacco essential oil) capable of reflecting the tobacco smell from tobacco to the best can be extracted.
Description
Technical field
The present invention relates to electronic cigarette, especially relate to and a kind ofly by supercritical extraction method, tobacco is best embodied to the method that the volatile aroma material (essential oil of tobaccos) of tobacco smell extracts.
Background technology
Electronic cigarette is to heat by electronic striking, allows the tobacco component of simulation become gas from liquid, has smog to extract out, and perceptual image is smoked the same, does not burn, and does not have new objectionable impurities and produces, and electronic cigarette is more healthy than conventional cigarette thus.As the raw material of electronic cigarette---atomized liquid, the composition of electronic atomized liquid is mainly solvent propylene glycol, glycerol, essence spice for cigarette, tobacco extract.And the extract now extracting from tobacco, what wherein volatile aroma material can be retained is little, and volatile aroma material is the chief component of tobacco leaf smell, but it is synthetic that essence spice for cigarette is all much artificial chemistry, makes the electronic cigarette on market have larger smell difference with traditional cigarette in sucking.The smell difference of electronic cigarette has become a significant obstacle that hinders electronic cigarette development.
Summary of the invention
For overcoming the shortcoming of existing electronic cigarette, the object of the present invention is to provide a kind ofly by supercritical extraction method, tobacco to be best embodied to the method that the volatile aroma material (essential oil of tobaccos) of tobacco smell extracts.
The present invention realizes by following technical measures, a kind of supercritical extraction method of essential oil of tobaccos, and it comprises the following steps:
Take a certain amount of offal and put into extraction kettle, be filled with CO from extraction kettle bottom
2as extracting fluid, its internal circulating load is 2-5 times of offal weight in extraction kettle; Extracting pressure in extraction kettle is 250-300bar, and temperature is 40-60 ℃; First carry out static extracting, static extracting adds dehydrated alcohol by the 5-8% of offal weight, static extracting 30min, then dynamic extraction 1-3h; In separating still, obtain product essential oil of tobaccos.
As a kind of optimal way, in described extraction fluid, be also added with entrainment agent, described entrainment agent is dehydrated alcohol, entrainment agent addition is CO
2the 3-5% of internal circulating load.
As a kind of optimal way, the tobacco leaf that described offal is natural air drying is at temperature 100-120 ℃ of dry 1-2h, is crushed to 200-300 object powder with pulverizer.
Supercutical fluid has the diffustivity of similar gas and the dissolving power of liquid, has low-viscosity concurrently simultaneously, and the characteristic of low surface tension makes supercutical fluid can rapid permeability enter the material of microporosity.Therefore extraction rate is quicker and effective than liquid when extracting, and especially dissolving power can be with temperature, pressure and polarity and change.Supercritical fluid extraction sepn process is to utilize the dissolving power of supercutical fluid and the relation of its density, utilize pressure and temperature to carry out the impact of supercutical fluid dissolving power. when material is during in supercritical state, become the single phase of character between liquids and gases, there is the density close with liquid, though viscosity is higher than gas but be starkly lower than liquid, spread coefficient is 10～100 times of liquid, therefore material is had to good perviousness and stronger dissolving power, some composition in material can be extracted.Carbonic acid gas is conventional solvent.Its critical temperature is 31.5 ℃, emergent pressure 7.38MPa.As supercritical extraction fluid, it has many distinctive features, and for example stagnation point easily reaches, generally do not react with extract, colourless, tasteless, nontoxic, odorless, use safety, nonflammable, easily remove, easily reclaim, inexpensive, environment is not produced to pollution, have fungistatic effect, therefore, it is used widely in light industry, food, medicine and other fields.
The present invention utilizes CO
2as the supercritical extraction method that extracts fluid, offal is extracted, can by the jononeionone in offal and 3-keto-ionone and other volatile aroma material, according to it, the proportion of composing in tobacco extracts, the perfuming that the essential oil of tobaccos of this method extraction is applied to electronic cigarette atomizing liquid or common tobacco, its effect is far longer than all kinds of monomers or compound essence; It not only can be used to tobacco flavoring, also can widespread use in food, cosmetics of everyday use blending.In electronic cigarette atomizing liquid formula, the effect of the essential oil of tobaccos of present method processing is the disappearance that makes up this perfume (or spice) of tobacco in tobacco tar, plays the effect of bringing out cigarette perfume (or spice); Jononeionone and 3-keto-ionone play modifies tobacco tar fragrance, can promote the tobacco tar effect of the property sent out and joyful sense thoroughly.The feature of the product that this method is extracted is, this perfume of tobacco is outstanding, and just, thoroughly send out, joyful sense is strong for fragrance alcohol.
Embodiment
Below in conjunction with embodiment, the present invention is described in further detail.
A supercritical extraction method for essential oil of tobaccos, it comprises the following steps:
