Abstract
The invention discloses tobacco flower essential oil prepared from tobacco waste and an application and preparation method thereof. Tobacco flower which is tobacco waste is extracted by using a flash extraction device and then is subjected to molecular distillation to finally obtain the tobacco flower essential oil. When in use, the tobacco flower essential oil is dissolved in a proper amount of ethyl alcohol and then is diluted with distilled water until the mass concentration is 1%, and the diluted solution is used as a component of tobacco liquid of electronic cigarette. The preparation method of the tobacco flower essential oil particularly comprises the following steps: extracting tobacco flower in the presence of an organic solvent under the voltage of 100-250 V for 5-90s to obtain crude oil, wherein the mass ratio of the tobacco flower to the organic solvent is 1:(2-10); and carrying out molecular distillation on the crude oil under the conditions that the pressure is 50-300Pa, the temperature is 50-80 DEG C, the feeding rate is 2-6mL/min and the knifing rate is 250-300r/min. According to the preparation method, the essential oil is extracted from the raw material tobacco flower, and therefore, the resource waste is reduced; due to combination of a flash extraction technique and the molecular distillation, the operation flow is simple and convenient, the extraction efficiency is high, and the tobacco flower essential oil still can retain stable fragrance after being stored for a long time; due to application of the tobacco flower essential oil, the tobacco liquid of the electronic cigarette has the original fragrance of tobacco.
Description
Technical field
The present invention relates to the extraction and application of natural perfume, be specifically related to a kind of utilize land for growing field crops tobacco leaf waste to prepare fireworks essential oil, preparation method and this application of fireworks essential oil in tobacco juice for electronic smoke.
Background technology
Land for growing field crops tobacco leaf, in process of growth, when cigarette strain is bloomed, needs to extract the fireworks on cigarette strain top, to ensure the nutritional needs of tobacco leaf to greatest extent.China has the fireworks of up to ten thousand tons to be abandoned field by as waste every year, and this not only causes the waste of resource, also causes the propagation of tobacco diseases.
Fireworks are turned waste into wealth, not only reduces the waste of resource, but also be a research with very big economic worth.At present, the utilization of waste material research of fireworks is less, mainly prepares fireworks medicinal extract.Chinese patent CN103190693A, CN1029768C all adopt solvent extraction method directly to prepare fireworks crude extract, and are applied in discarded tobacco leaf, tobacco sheet.Prepare fireworks essential oil for fireworks, Chinese patent CN10379091A adopts carbon dioxide supercritical extraction method to prepare fireworks essential oil, and is applied in cigarette shreds.The fireworks medicinal extract that these methods extract and fireworks essential oil all do not carry out further retrofit, due to containing the volatile composition of some lower boilings, there is the problem of fragrance style instability.
Homogenate extraction technology utilizes high speed machine shearing force and whipping force, rapid destruction plant cell tissue, that the inner effective constituent of histocyte fully contacts with solvent, effective constituent rapid solution is shifted, inside and outside dissolution equilibrium is reached within very short time, shorten extraction time, improve extraction efficiency, simplify operating process.
Summary of the invention
Instant invention overcomes the deficiencies in the prior art, provide a kind of utilize tobacco waste to prepare fireworks essential oil and application and preparation method, tobacco waste is better applied.
For solving above-mentioned technical problem, one embodiment of the present invention by the following technical solutions:
The fireworks essential oil utilizing tobacco waste to prepare, it after flash extracter extraction obtains the thick oil of fireworks, again thick for fireworks oil is carried out molecular distillation preparation by tobacco waste fireworks and obtains.
Further technical scheme is: described fireworks be selected from flue-cured tobacco bud, burley tobaccos bud, Turkish tobaccos bud one or more.
Present invention also offers the application of fireworks essential oil, described fireworks essential oil is dissolved in ethanol in proper amount, and being diluted with distilled water into fireworks essential oil solution, in described fireworks essential oil solution, the mass concentration of fireworks essential oil is 1%, and described fireworks essential oil solution is as the component of tobacco juice for electronic smoke.
Further technical scheme is: the concrete formula of described tobacco juice for electronic smoke is: parts by weights meter, propylene glycol 40 ~ 50 parts, glycerol 34 ~ 45 parts, 1 ~ 2 part, nicotine, described fireworks essential oil solution 5 ~ 8 parts, distilled water 5 ~ 9 parts.
Further technical scheme is: the concrete formula of described tobacco juice for electronic smoke is: parts by weights meter, propylene glycol 40 parts, glycerol 45 parts, 2 parts, nicotine, described fireworks essential oil solution 8 parts, distilled water 5 parts.Adopt the tobacco juice for electronic smoke of this formula gained that smoker can be made to obtain larger satisfaction, and tobacco juice for electronic smoke fragrance is stronger, assorted gas is few, and pleasant impression is comfortable long.
Present invention also offers a kind of method utilizing tobacco waste to prepare fireworks essential oil, it comprises the following steps:
(1) by tobacco waste fireworks dry to water content be 12% ~ 14%, then get 100 ~ 200g fireworks and be placed in flash extracter, add organic solvent, 5 ~ 90s is extracted under the condition of fireworks and organic solvent mass ratio 1:2 ~ 10, voltage 100 ~ 250V, cooling, filtration, filtrate is steamed except organic solvent through Rotary Evaporators, obtains fireworks slightly oily;
(2) thick for fireworks oil is carried out molecular distillation under the condition of pressure 50 ~ 300Pa, temperature 50 ~ 80 DEG C, feed rate 2 ~ 6mL/min, knifing speed 250 ~ 300r/min, collect distillment, be fireworks essential oil.
Further technical scheme is: step (1) described fireworks and organic solvent mass ratio are 1:10, and the extraction voltage of flash extracter is 100V, and extraction time is 5s.Carry out homogenate extraction under this condition, the abundant stripping of the essential oil in fireworks can be made.
Further technical scheme is: the thick oil of step (2) described fireworks carries out molecular distillation under the condition of pressure 50Pa, temperature 50 C, feed rate 2mL/min, knifing speed 250r/min.Carry out molecular distillation under this condition and can get rid of lower boiling molecule, increase the fragrance of fireworks essential oil, reduce pungency, remove assorted gas.
Further technical scheme is: described organic solvent is selected from one or more in normal hexane, ethyl acetate, ethanol.
Compared with prior art, one of beneficial effect of the present invention is: the present invention is that raw material extracts essential oil with fireworks, is turned waste into wealth by land for growing field crops waste, decreases the waste of resource; In leaching process, adopt the means that homogenate extraction technology combines with molecular distillation, not only operating process is easy, extraction efficiency is high, and the fireworks essential oil obtained eliminates low boiling point component, during prolonged storage, fragrance style keeps stable; Fireworks essential oil being applied in electronic cigarette liquid formula, making tobacco juice for electronic smoke have this perfume of tobacco, when aspirating, sense organ having the feature style of traditional cigarette.
