Abstract
The invention provides a method for extracting antioxidant from smashed tobacco powder, and relates to application for extracting the antioxidant from the smashed tobacco powder and application as cigarette aromatic flavouring by serving as tobacco additive. The antioxidant is prepared according to the following method: smashing tobacco, heating solvent, carrying out reflux extraction, condensing, carrying out molecular distillation, acidizing, extracting, and condensing to obtain the antioxidant product. The invention is characterized in that smashed tobacco powder is adopted for reflux in solvent; after condensation, molecular distillation is carried out; after the obtained light constituent is acidized, organic solvent is added and is mixed and extracted at the ratio of 1:0.5-1:0.8; organic phases are combined and condensed to obtain a flavescent product; the yield of the product is 10-15%, and the content of the antioxidant in the product is more than 6.8%. When used for extracting the antioxidant from smashed tobacco powder, the method has abundant raw material, short process route and controllable process and is suitable for industrial production. Selected from tobacco, the raw material is more suitable for serving as cigarette additive to be applied on cigarette cut tobacco and a filter tip to obtain the effect on clearing free radicals.
Description
Technical field
The present invention relates to a kind of method of from the broken end of tobacco, extracting antioxidant, particularly utilize molecular distillation technique to combine with solvent extraction, from the broken end of tobacco, extract the method for tobacco antioxidant.
The antioxidant raw material sources of the present invention's preparation also will be applied in the tobacco product in tobacco, and will be safe, be a kind of novel tobacco antioxidants.
Background technology
In recent years, in the world in the more and clearer and more definite cigarette composition to human body harm maximum be not nicotine, but free radical.Contain the very high free radical of a large amount of activity in the cigarette smoke, about smoking and healthy discover that the free radical in the cigarette smoke is the principal element that causes atherosclerotic, miocardial infarction and hypertension etc.In addition, the free radical in the flue gas is also relevant with a lot of diseases such as aging, PUD D, gastric ulcer, Alzheimer disease, the gloomy disease of platinum and tumour.Therefore will prevent and treat the disease that causes because of smoking, the free radical that should reduce in the flue gas enters in the human body in fact.
Reach the purpose that reduces the free radical in the tobacco, can consider in tobacco, to add proper quantity of antioxidant, can reach the effect of removing free radical.Antioxidant refers to suppress the material of free-radical oxidation speed, the material that just can remove free radical and prevent the free radical activity.
The general antioxidant that uses is mainly butylated hydroxy anisole (BHA), dibutyl hydroxy toluene (BHT) and n-propyl gallate synthetized oxidation preventive agents such as (PG) at present.Yet zoopery shows: there is potential harm in synthetized oxidation preventive agent to the health of human body, and side effect increases on the contrary.Therefore, more and more noticeable from the natural anti-oxidation of plant.The natural plant that contains antioxidant has rosemary,, soybean, mango, thorn to add five etc. in the relevant report, the natural commodity of external supply the market have 47 kinds of Rosmarinus officinalis extract, Sage extract, Radix Glycyrrhizae polyphenoils, Tea Polyphenols, ellagic acid, sunflower seed extracts etc., and the application in tobacco product has very big development prospect.And domestic present prevailing antioxidant still is synthetic butylated hydroxy anisole (BHA), dibutyl hydroxy toluene (BHT) and n-propyl gallate (PG) and ditert-butylhydro quinone (TBH Q), the relevant report of natural Products Development and application is actually rare.
Tobacco is as a kind of natural plants, and existing a large amount of reported in literature wherein contains antioxidant composition.But have nothing to do temporarily at present in therefrom extract its antioxidant report from tobacco material.The present invention by adopting corresponding physics and chemical method and means, extracts the antioxidant in the tobacco as breakthrough.
Summary of the invention
The present invention is by extraction separation antioxidant from the broken end of tobacco and as the application of tobacco additive agent in perfuming cigarette, antioxidant among the present invention is joined in cigarette shreds or the filter tip, can reduce the activity of free radical in the cigarette smoke, reach the effect that reduces free radical, simultaneously can improve the flue gas quality, strengthen and enrich mouthfeel, reduce excitant, reduce assorted gas.
The present invention makes by the following method: the broken end of tobacco → solvent heating and refluxing extraction → concentrate → molecular clock → acidifying → extraction → concentrate → antioxidant product.
Be characterized in: directly adopt the broken end of tobacco in solvent refluxing, to obtain to contain the extract of antioxidant, carrying out molecular clock after concentrating handles, the light component that obtains is carried out adding organic solvent after the acidifying, carry out hybrid extraction with 1: 0.5 to 1: 0.8 ratio, merge organic phase, concentrate the back and obtain lurid product, product yield 10%-15%, the content of antioxidant in the product (main component is dibutyl hydroxy toluene (BHT)) is greater than 6.8%.
The invention has the advantages that: use extraction that molecularly distilled carries out the broken last antioxidant of the tobacco antioxidant in the broken end of separate tobacco first, raw material is easy to get, and process route is short, and process is controlled, is fit to industrial production.Because raw material sources in tobacco, are more suitable for being applied on cigarette shreds and the filter tip as cigarette additive, reach the effect of removing free radical, for tobacco flavoring provides a kind of novel, important natural anti-oxidation material.
