Description

A kind of preparation method and applications of cigarette blackberry extract
Technical field
The application that the present invention relates to natural plant extracts in tobacco product, specifically a kind of cigarette blackberry extract Preparation method and applications.
Background technique
" Chinese-style cigarette " core competitiveness is to form selling point style, embodies personalized and differentiation, and it is wide to adapt to China Big consumer's sucks habit and consumer need.Chinese style essence spice for cigarette is Chinese-style cigarette product " soul ", is Chinese style volume Where the secret that cigarette style characteristic is formed.The scientifically flavoring and casing in cigarette, the personalized style of exactly prominent cigarette product Important means.Meanwhile in order to improve the safety of smoking, lowering harm and decreasing coking has become an important composition portion of " Chinese-style cigarette " Point.While reducing coke tar in cigarette, promotes and improve flue gas concentration and fragrance, also only by means of flavoring and casing technology.With Chinese-style cigarette lowering harm and decreasing coking work go deep into, tobacco flavoring charging show its importance further.
The Chinese style essence spice for cigarette and new technology for constructing independent intellectual property right, extract flavors and fragrances from natural plants, It allows the theory of health with the refined perfume (or spice) of cigarette, moves towards consumer together, be one of the basic research for developing " Chinese-style cigarette ".
For blackberry, blueberry rich in a variety of latent Studies of The Aromatic Substances such as flavonoids, cigarette perfume can be enriched by making an addition in cigarette product, make flue gas more It is full.The present inventor has found in the course of the research: existing blackberry, blueberry extraction process is lower to the extraction efficiency of latent Studies of The Aromatic Substances and black For the certain kind of berries in integrally extracting, being mixed into for the substances such as pectin can bring certain negative effect to cigarette product, increase separating technology again The latent Studies of The Aromatic Substances of extraction can be damaged, to limit its purposes as cigarette additive.
Summary of the invention
The purpose of the present invention is to the deficiencies in the prior art, provide a kind of cigarette blackberry extract preparation method and It is applied, and uses blackberry, blueberry to extract raw material, and blackberry, blueberry filters after crushing mashing, after filtrate n-hexane extraction, sloughs solvent;Filter Slag is placed in alkaline aqueous solution and hydrolyzes, and is extracted after aqueous portion is dry with ethanol solution;The two is mixed in a certain ratio, and obtains cigarette Use blackberry extract.
A kind of preparation method of cigarette blackberry extract, the specific steps are as follows:
(1) blackberry, blueberry cleaned up is placed in refiner, squeezes filtering after crushing mashing, obtains filtrate and filter residue;
(2) using n-hexane as extractant, the resulting filtrate of step (1) and n-hexane are filled according to mass ratio for 1:1~10 After dividing mixing, vibrate 1~5 hour, settle and separate goes out organic phase, and the organic phase after separation is concentrated into medicinal extract shape, sloughs completely just Hexane is to get product 1;
(3) first alkali is added to the water, adjusting pH value is 8.0~12.0, and the weight ratio according still further to aqueous slkali and filter residue is 10~20:1 is mixed, and is heated 1~5 hour at 50~90 DEG C, and being eventually adding organic acid for adjusting pH value is 7.0, separation discharging After liquid, feed liquid is concentrated into medicinal extract shape;
(4) using 70~95% ethyl alcohol as extractant, by the resulting medicinal extract of step (3) and ethyl alcohol according to mass ratio be 1:1~ 10, it after being sufficiently mixed, vibrates 1~5 hour, filters to get product 2.
(5) product 1,2 is mixed in a certain ratio to get cigarette blackberry extract of the invention;In parts by mass, wherein Product 1 is 10~40 parts, product 2 is 30~80 parts.
Further, the time of repose in the step (2) is 2 hours.
Further, the organic acid is acetic acid, citric acid, malic acid or citric acid.
Further, the alkali is sodium hydroxide, calcium hydroxide, potassium hydroxide or sodium carbonate.
Cigarette blackberry extract is added according to mass ratio 0.01%~0.05% for a kind of application of cigarette blackberry extract Into the pipe tobacco of cigarette.
Further, cigarette blackberry extract is added in the pipe tobacco of cigarette according to mass ratio 0.02%~0.04%.
Further, cigarette is added to the specific steps of pipe tobacco with blackberry extract are as follows: be dissolved in blackberry extract cigarette molten In agent, it will be sprayed on pipe tobacco, then evaporate molten during the pipe tobacco of production of cigarettes rolls dissolved with the solvent of blackberry extract Agent.
Further, the solvent is the ethyl alcohol that mass concentration is 95%.
The present inventor shows that the blackberry extract of addition is aspirated in tobacco product by a series of experimental studies of smokeing panel test Shi Xiangqi is abundant, flue gas is full, improves tobacco product mouthfeel.
Invention increases blackberry, blueberry new effects and effect.For blackberry extract as additive of tobacco product, effect is obvious, There is " Chinese-style cigarette " product of distinctive style to have good application prospect exploitation.
