Abstract
The invention discloses the liquid essences that a kind of perfume quantity and aroma quality protrude, after it is by the mixture alcohol extracting-water precipitating by a variety of tobacco leaves, it is concentrated into certain alcoholic strength, loading macroporous resin column again, and successively use three times volume 20% ethyl alcohol, 35 45% ethyl alcohol, 100% ethanol elution, collect 100% ethanol eluate and be concentrated into certain relative density and refraction index both the perfume quantity and aroma quality protrusion liquid essence.The liquid essence perfume quantity and aroma quality of the present invention protrudes, and can reduce the quality fluctuation of cigarette product that quality of tobacco is brought as the necessary essence for stablizing cigarette style characteristic.
Description
Technical field
The invention belongs to essence spice for cigarette technical field, specifically, being prepared from tobacco leaf the present invention relates to a kind of
The liquid essence that perfume quantity and aroma quality protrude.Meanwhile the application the invention further relates to the liquid essence in cigarette.
Background technology
Cigarette style characteristic refers to the note that people brings experience during cigarette smoking, and good cigarette product is respectively provided with oneself phase
The style and features stablized to unique.It is that tobacco leaf and essence are fragrant to influence two the most key objective factors of cigarette style characteristic
Material.Tobacco leaf by the various extraneous factors such as region, illumination, moisture, temperature due to being influenced so that the quality of tobacco of different year has
Larger fluctuation controls its stable quality relatively difficult.Therefore the perfume (or spice) highlighted from essence and flavoring agent angle, exploitation with style and features
Essence reduces cigarette style characteristic and is changed by quality of tobacco fluctuation, is very meaningful work.
The tobacco essence fragrance with specific style feature is developed, and is added in cigarette to protrude being somebody's turn to do for cigarette
Specific style feature is always the important directions of tobacco enterprise fragrance research and development.But current research is asked there are directive property is not strong
Topic, such result brought of studying is often that the tobacco essence fragrance product developed is needed by a large amount of application test
Suitable application product can be found or even the cigarette product for being suitble to its feature can not be found, cause the waste of research.
Macroreticular resin is the polymer of a quasi-styrene, be can be achieved according to polarity difference rich to the selectivity of different organic matters
Collection；Macroreticular resin has certain pore size simultaneously, can also realize the volume exclusion separation by molecular weight.
The present invention utilizes the Selective Separation feature of macroreticular resin, is eluted using macroporous resin column combination solvent selectivity,
The flavor components that specific organoleptic quality protrudes can be obtained, effectively remove the tobacco unrelated or even unfavorable to screening organoleptic quality into
Point, fragrance cigarette can be highlighted to exploitation and had great importance.
Invention content
It is an object of the invention to the steady demands according to cigarette to style and features, develop a kind of perfume quantity and aroma quality is dashed forward
The tobacco abstract gone out is as liquid tobacco essence.
The present invention also aims to the liquid tobacco essence is applied in cigarette.
The purpose of the present invention is achieved by following technical proposals.
Unless otherwise indicated, percentage of the present invention is mass percent.
