Abstract

The invention discloses electronic cigarette liquid with characteristics of tobaccos for tobacco pipes. The electronic cigarette liquid is characterized by being made of, by weight, 5-40% of tobacco extracts, 5%-20% of tobacco essences, 0.5%-2.0% of nicotine, 5%-10% of deionized water, 10%-20% of glycerin and the rest of propylene glycol. The tobacco extracts are extracted from raw tobaccos, and light components are taken after molecular distillation. In order to highlight tobacco characteristics including high fragrance, high penetration, high satisfaction and the like, the raw tobaccos are taken as raw materials of the tobacco extracts; in order to reduce content of high-boiling-point substances in the extracts, the tobacco extracts are separated by means of molecular distillation and are light components after molecular distillation, the light components make fragrance and taste of the electronic cigarettes to be closer to those of traditional cigarettes, deposition of nonvolatile substances on heating wires of the electronic cigarettes is avoided, and service lives of the heating wires of the electronic cigarettes are prolonged while taste of electronic cigarette products is improved.

Description

A kind of tobacco juice for electronic smoke with pipe tobacco style and features
Technical field
The invention belongs to tobacco juice for electronic smoke technical field, be specifically related to a kind of tobacco juice for electronic smoke with pipe tobacco style and features.
Background technology
Along with coming into effect of " Framework Convention on Tobacco Control ", smoking ban scope in public place, countries in the world progressively expands, and domestic and international tobacco consumption environment just profound change occurs.Electronic cigarette, because it is not containing the harmful components such as tar, CO, does not produce the features such as second-hand-cigarette, receives increasing concern.Tobacco juice for electronic smoke, primarily of propane diols, glycerine and nicotine composition, being aided with various essence to improve taste, having the various tastes such as coffee, peppermint, strawberry.In addition, have also appeared the tobacco juice for electronic smoke of several functions type in recent years, as tooth health (CN 201010254808.4), health-care throat-moistening type (CN 201010576200.3), slim functional form (CN 201010254798.4), medicinal health type (CN 200910104921.1), caries prevention type (CN 200910105219.7) etc. are good in whitening.But electronic cigarette product tobacco aroma is in the market more weak, the use of a large amount of essence and flavoring agent, make electronic cigarette in fragrance, mouthfeel etc., differ comparatively large with traditional cigarette, consumer is difficult to accept, and even has nauseating sensation.These shortcomings or deficiency constrain the development of electronic cigarette, thus, how to improve the quality of tobacco juice for electronic smoke, make it can meet the psychological need of consumer, can reach again certain psychic gratification sense, have important function to the development of electronic cigarette.
In recent years, abroad on market, the consumer group of pipe tobacco increases gradually, and pipe tobacco specializes in use the tobacco product that smokes of tobacco pipe, has sheet or strip or the various shape such as thread.Pipe tobacco gives off a strong fragrance when sucking, and by force, a people aspirates houseful lasting, not only can meet the psychological need of consumer, and strong fragrance makes people be in a cheerful frame of mind, thus rather well received for penetration power and diffusivity.High fragrance high satisfaction that pipe tobacco possesses just electronic cigarette needs improvement badly, although the taste of electronic cigarette has a lot at present, not yet has the tobacco juice for electronic smoke of pipe tobacco style and features.
Summary of the invention
The shortcomings such as the cigarette perfume (or spice) that the object of the invention is to exist for tobacco juice for electronic smoke is not dense, mouthfeel is poor, provide a kind of tobacco juice for electronic smoke with pipe tobacco style and features.Described tobacco juice has the feature of similar pipe tobacco, namely cigarette aromatic strongly fragrant, penetration power is strong, diffusivity good, satisfaction is strong, can meet the Physiological and psychological requirements of consumer.
For achieving the above object, the present invention adopts following technical scheme:
Have a tobacco juice for electronic smoke for pipe tobacco style and features, become by the mixed raw material of following percetage by weight: tobacco extract 5-40%, flavouring essence for tobacco 5%-20%, nicotine 0.5%-2.0%, deionized water 5%-10%, glycerine 10%-20%, surplus is propane diols; Described tobacco extract is with hair cigarette for raw material extracts, and this extract is by getting its light component after molecular clock process.
For highlighting the features such as pipe tobacco height fragrance, high satisfaction, tobacco material described in the present invention is hair cigarette, and especially with the solarization Huang that Yunnan Mao Yanwei represents, and the solarization that Sichuan Mao Yanwei represents is red; The object of employing molecular clock process is the content in order to reduce high boiling substance in tobacco extract, improves the mouthfeel of electronic cigarette.
In the present invention, the preparation method of tobacco extract specifically comprises the following steps: raw meal is broken to 10 ~ 100 orders by (1); (2) add organic solvent and carry out lixiviate; (3) be separated leaching liquor after filtering, leaching liquor reduced pressure concentration obtains tobacco extract; (4) ethanol back dissolving, freezing dewaxing: the high concentration ethanol (95% ethanol or absolute ethyl alcohol) adding 5 ~ 10 times of quality in gained tobacco extract, after abundant dissolving, this solution is placed in refrigerator (0 ~-20 DEG C) freezing 8 ~ 20 h, after insoluble matter is fully separated out, decompress filter or centrifugation supernatant, supernatant reduced pressure concentration obtains tobacco concentrate; (5) molecular clock: gained concentrate can directly be separated with molecular clock, or carries out molecular clock separation again after adding propane diols dissolving, and the consumption adding propane diols is 1 ~ 3 times of concentrate quality, described molecular clock condition: vacuum 1 ~ 10 -2mbar, vapo(u)rizing temperature 50-100 DEG C, scraper plate rotating speed 150-240 rpm, charging rate 2-5 mL/min, collect light component after molecular clock is separated and namely obtain described tobacco extract.
At least one in described step (2) during extraction in organic solvent benzinum used, ethyl acetate, ether, 95% ethanol, absolute ethyl alcohol etc., feed liquid mass ratio is 1:6 ~ 1:10, and extraction time is 1 ~ 3 h.
Described flavouring essence for tobacco is made up of the material of following percentage by weight: oxidation isophorone 0.1%-3%, natural herb 1%-5%, vanillic aldehyde 0.1%-1%, blueberry extract 1%-10%, guaiacol 0.5%-2%, Megastigmatrienone 3%-5%, cocoa extract 1%-10%, ethanol 1%-15%, surplus are propane diols.
In order to make the application obtain good effect, described nicotine is natural nicotine.
Relative to prior art, the present invention has the following advantages:
(1) for highlighting the style and features of pipe tobacco height fragrance high satisfaction, in the present invention with hair cigarette for raw material, especially Yunnan hair cigarette and Sichuan hair cigarette.Yunnan hair cigarette is cut into willow leaf by light, and because its pipe tobacco is soft, the thin hair cigarette as therefore named in hair of silk, fragrant odour is one of main component of pipe tobacco pipe tobacco.Sichuan hair cigarette adopts paste rice water processing method to ferment further usually, decapacitation is played outside general fermentation (clear water fermentation) usefulness, also has its unique strong point: improve flavor and taste further, smell and have a kind of sour-sweet fragrance, suction fragrance is plentiful, pure, and pleasant impression is pure, comfortable.
(2) tobacco extract that tobacco juice for electronic smoke of the present invention is used, through molecular clock process, can not have volatile-resistant substance to be deposited on the heater strip of electronic cigarette, can improve the life-span of electronic cigarette heater strip and the mouthfeel of electronic cigarette product.
