Description
Technical field
The present invention relates to the application of a kind of natural plant extracts in tobacco product, specifically a kind of Radix Rhodiolae extract and as the purposes of additive of tobacco product.
Background technology
" Chinese style cigarette " core competitiveness is to form the selling point style, embodies personalization and differentiation, adapts to sucking of Chinese consumers in general and is accustomed to and consumer need.Chinese style cigarette essence and flavoring agent is Chinese style cigarette product " soul ", is the secret place that " Chinese style cigarette " style characteristic forms.Flavoring and casing scientifically in cigarette, the important means of the personalized style of outstanding cigarette product just.Simultaneously, in order to improve the security of smoking, lowering harm and decreasing coking becomes an important component part of " Chinese style cigarette ".When reducing coke tar in cigarette, promote and raising flue gas concentration and fragrance, also only by means of the flavoring and casing technology.Along with going deep into of Chinese style cigarette lowering harm and decreasing coking work, reinforced its importance that demonstrates further of tobacco flavoring.Extracting essence and flavoring agent from the natural herbal plant, succession herbal medicine in thousand is used for cigarette, allow healthy theory along with the refined perfume (or spice) of cigarette, move towards the human consumer together, is one of fundamental research of development " Chinese style cigarette ".
Contain multiple flavonoid compound in the Root of Kirilow Rhodiola, have prospect as essence spice for cigarette.Multiple functions such as Root of Kirilow Rhodiola has enhance immunity power, builds up health, improves the human body hematopoietic function, anti-hypoxia, anti-ageing, antitumor, antifatigue, hypoglycemic, antiviral, radioprotective, prevention altitude sickness can be used for the work of cigarette harm reduction.But the achievement in research that sees report at present has only Root of Kirilow Rhodiola to be used in Chinese medicine and correlated product, the nourishing drink, and not seeing has the bibliographical information that is used to cigaret additive.And in our research process, discovery is simple to have bigger negative effect by the resulting Radix Rhodiolae extract of conventional extraction process, can't satisfy the service requirements as cigaret additive.
Summary of the invention
Purpose of the present invention is exactly the defective at prior art, provides a kind of Radix Rhodiolae extract and as the purposes of additive of tobacco product.
Technical scheme of the present invention is achieved in that it is to adopt Root of Kirilow Rhodiola for extracting raw material, with the polar solvent is extraction agent, carry out abstraction reaction, adopting alkali to put forward the heavy isolation technique of acid will extract byproduct and separate, again throw out is dissolved with extraction agent, filtering separation once more, the gained feed liquid is extract of the present invention.
Wherein said extraction agent is 40～80% aqueous ethanolic solution.
Extracting method of the present invention is to adopt Root of Kirilow Rhodiola for extracting raw material, specifically may further comprise the steps: earlier alkali is joined in the extraction agent, regulating extraction agent pH value is 8.0～12.0, extraction agent is 10～20: 1 with the weight ratio of extracting raw material, extracted 1～5 hour at 50～90 ℃, after isolating feed liquid, feed liquid is concentrated into 1/3 of original volume, add organic acid in concentrated solution, regulating the pH value is 3.5～5.5, filtering separation gained precipitation, with 5～10 times of extraction agent dissolvings, the filtering separation insolubles is concentrated into the medicinal extract shape once more with feed liquid once more, promptly obtains Radix Rhodiolae extract of the present invention.Wherein said extraction agent is 40～80% aqueous ethanolic solution.
The present invention is as the purposes of additive of tobacco product: it is that Radix Rhodiolae extract is added in the pipe tobacco of cigarette, the Radix Rhodiolae extract that is added in the pipe tobacco accounts for 0.01%～0.05% of pipe tobacco weight, flavouring effectively when tobacco product aspirates, and fragrance is abundant, increases the solid sense of flue gas.The Radix Rhodiolae extract that wherein is added in the pipe tobacco preferably accounts for 0.02%～0.04% of pipe tobacco weight.
The present invention is during as the purposes of additive of tobacco product, preferably Radix Rhodiolae extract is dissolved in 70% the ethanol, the alcohol solvent that is dissolved with Radix Rhodiolae extract rolled at the pipe tobacco of production of cigarettes be sprayed in the process on the pipe tobacco, subsequently evaporating solvent.
Extracting method of the present invention technical scheme preferably is that described alkali is sodium hydroxide, calcium hydroxide, ammoniacal liquor or yellow soda ash; Described acid is toluylic acid, citric acid, oxysuccinic acid or Citric Acid; Described extraction agent is 40～80% aqueous ethanolic solution.
A series of experimental study results that smoke panel test of patent applicant show, the Radix Rhodiolae extract of adding flavouring effectively when tobacco product aspirates, and fragrance is abundant, increases the solid sense of flue gas; And Radix Rhodiolae extract can also be given the aromatic and the note of tobacco product uniqueness.And when improving the tobacco product mouthfeel, can avoid introducing negative impacts such as assorted gas, increase pungency.
The present invention has opened up a new Application Areas for Radix Rhodiolae extract, has increased new effect and the effect of Root of Kirilow Rhodiola.Radix Rhodiolae extract is as additive of tobacco product, and effect is obvious, and " Chinese style cigarette " goods of developing characteristic style are had good application prospects.
