One preparation method who grows tobacco colored volatile matter extracting method and microcapsule thereofTechnical field
The present invention relates to a preparation method who grows tobacco colored volatile matter extracting method and microcapsule thereof, belong to light industry processing technique field.
Background technology
Tobacco is Solanaceae annual herb plant, and the nearly kind more than 60 of Nicotiana, but really for the manufacture of cigarette and pipe tobacco, substantially only have safflower tobacco also has small part in addition with Folium Nicotianae rusticae, and other kinds are seldom used.Tobacco is the plant of Solanaceae (nightshade family) that one belongs to Nicotiana (Nicotiana), at present, people are separated out in tobacco and flue gas and are had hundreds of aroma components by advanced analytical instrument, can adopt the technology such as extraction and synthetic to produce needed monomer essence.The essence extracting from tobacco is used further to production of cigarettes, can improves better the fragrance value of cigarette product.Tobacco extract can extract from the tobacco of any type, and wherein tobacco flower concrete has gentle tobacco flowery odour, like fresh and sweet as Acacia, can be directly used in cigarette and perfuming tobacco thin sheet.But the extractive technique to tobacco in existing technology and apply less.Patent of invention (201310178550.8) " is utilized supercritical CO2the method of tobacco extrait is prepared in extraction " disclose one and utilized supercritical CO2abstraction technique is prepared the method for tobacco extrait, and after tobacco extrait extracts, fragrance is difficult to ensure, application is restricted.
Summary of the invention
The object of the present invention is to provide a preparation method who grows tobacco colored volatile matter extracting method and microcapsule thereof.Tobacco volatile matter extracting method of the present invention is to utilize wet distillation to extract tobacco volatile matter, by tobacco is soaked, add salt, improve volatile matter extraction yield, then it is carried out to microcapsule preparation with colloid milling, use colloidal mill to prepare the microcapsule yield of Benexate Hydrochloride high, the inclusion time is short, temperature is low, output is large, take up room little, processing condition are easy to control, are applicable to enterprise's suitability for industrialized production.
Object of the present invention is achieved by the following technical programs:
Except as otherwise noted, percentage ratio of the present invention is weight percentage.
The one colored volatile matter extracting method that grows tobacco, is by tobacco chopping, weighs, and adds a certain amount of saliferous distilled water solution, soaks certain hour, and wet distillation is extracted, and collects cut, obtains tobacco volatile matter.
One preparation method who grows tobacco colored volatile matter microcapsule, gets tobacco volatile matter, adds equivalent 95% alcohol dilution, adds a certain amount of cyclodextrin and distilled water to mix, and grinds to form mashed prod with colloidal mill; By mashed prod decompress filter, with absolute ethanol washing, after suction filtration be deposited in 40-60 ℃ dry.
Tobacco volatile matter extracting method of the present invention, the mass ratio of described tobacco and saliferous distilled water is 1:10-15, the concentration of salt by weight percentage ratio is 1-10%.
The extracting method of tobacco volatile matter of the present invention, wet distillation extraction time is 2-4h.
The extracting method of tobacco volatile matter of the present invention, described salt is NaCl, Na2sO4, NaNO3one, soak time is 12-24h.
The preparation method of tobacco volatile matter microcapsule of the present invention, the mass ratio 1:3-6 of tobacco volatilization extract and cyclodextrin.
The preparation method of tobacco volatile matter microcapsule of the present invention, the mass ratio of cyclodextrin and distilled water is 1:3-6.
The preparation method of tobacco volatile matter microcapsule of the present invention, milling time is 10-20min.
The preparation method of tobacco volatile matter microcapsule of the present invention, cyclodextrin is the one of beta-cyclodextrin, hydroxypropyl-belta-cyclodextrin.
The preparation method of tobacco volatile matter microcapsule of the present invention, drying mode is the one of vacuum-drying and forced air drying method.
With respect to prior art, the present invention has following remarkable advantage:
1, the present invention utilizes wet distillation to extract tobacco volatile component, by tobacco is soaked, adds salt, improves volatile matter extraction yield.
2, with colloid milling, tobacco volatile matter is carried out to micro-capsule embedding, yield is high, and the inclusion time is short, temperature is low, output is large, takes up room little, and processing condition are easy to control, is applicable to enterprise's suitability for industrialized production.
3, the tobacco volatile matter microcapsule of preparation, are easy to use in tobacco processing.
