Description
Technical field
The invention belongs to active ingredient of natural plant extractive technique field, especially relate to a kind of preparation technology who is applicable to the extracting active ingredient of natural plant by supersonic of condiment product preparation field.
Background technology
Nowadays, extracting method for active ingredient of natural plant mainly is classical solvent extraction method, its principle is according to the different solubility of each composition in different solvents in the natural plants, select the volume large, little to impurity solubility to active ingredient solubility, active ingredient is dissolved out in plant tissue.Method commonly used in the solvent extraction method has: infusion process, percolation, decocting method, reflux extraction and continuous circumfluence extraction method.At present, suitability for industrialized production mainly adopts reflux extraction and continuous circumfluence extraction method, but still there are some shortcoming and defect parts in these two kinds of extracting methods in actual industrial production.
Wherein, the shortcoming and defect part of reflux extraction shows: 1, extraction efficiency is lower, and every batch extract to need more novel solvent two to three times; 2, the solvent use amount is larger, and operating process is comparatively loaded down with trivial details, takes a lot of work when boiling; 3, total extraction time longer, temperature is higher, the part loss of effective components or other chemical reaction occurs after so that product quality is subject to obvious impact.And the shortcoming and defect part of continuous circumfluence extraction method shows: the used time of leaching process is longer, generally need 5～8 hours, and it is relatively high to extract temperature, so the loss that can cause part thermally labile in the natural plants easily to be varied to minute to be thermal sensitivity active ingredient affects the product special flavour quality.
Summary of the invention
Technical problem to be solved by this invention is for above-mentioned deficiency of the prior art, a kind of preparation technology of extracting active ingredient of natural plant by supersonic is provided, it is saving of work and time and can obviously improve the quality of products and the product yield both, extract not only that required time is short, extraction efficiency is high, and the leaching process temperature is low, need not heat, when having avoided high-temperature heating to the destruction of active ingredient.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of preparation technology of extracting active ingredient of natural plant by supersonic is characterized in that this technique may further comprise the steps:
Step 1, clean dedusting: the natural plants to be extracted through being up to the standards is cleaned dedusting and dries or dry;
The inner screen cloth of installing of pulverizer described in the step 2 is 40 eye mesh screens.
The stir speed (S.S.) of agitator described in the step 3 is 60～100r/min.
Food organic solvent described in the step 3 is that volumetric concentration is 50～95% food-grade ethanol or food-grade acetone.
The quantity of supersonic generator described in the step 4 is a plurality of, and a plurality of supersonic generator is the inside bottom middle part that a horizontally-arranged evenly is laid in ultrosonic extractor.
Cleaning way described in the step 1 is dry cleaner dry-cleaning.
Hydraulic circulation pump one described in step 4 and the step 5 is screw pump.
200～300 eye mesh screens described in the step 5 are arranged on the bottom of filter, and the top of described filter and bottom correspondence are provided with the installing port that is respectively applied to install connecting pipe one and connecting pipe two, and described filter bottom is provided with slag notch; The top of hermetically sealed can and bottom correspondence are provided with the installing port that is respectively applied to install connecting pipe three described in connecting pipe two and the step 6; The top of the reduced pressure concentration tank described in the step 6 is provided with for the installing port that connecting pipe three is installed.
The present invention compared with prior art has the following advantages: 1, extraction rate is fast, required time is short: it is 4～7 hours that conventional water bath reflux method extracts required total time, it is 6～8 hours that the continuous circumfluence extraction method is extracted required total time, and ultrasonic continuous circulating extraction method of the present invention only needed get final product in 1～1.5 hour.2, extraction efficiency is high, traditional reflux extraction all needs by the diffusion of solvent itself and osmosis, cell membrane by natural plants to be extracted enters in the cell, cause concentration difference after the dissolving active ingredient, and then reuse and make intracellular solution reach dynamic equilibrium through coming and going exchange, thereby required time is longer, and efficient is lower; The present invention then utilizes hyperacoustic cavitation directly to destroy cell membrane, active ingredient is easy in the cell stripping and discharges, simultaneously ultrasonic wave is so that after extract constantly shaken, more be conducive to the solute diffusion, thereby further improved extraction efficiency.3, the product yield is high, the thermal sensitivity loss of effective components is few, product quality is high: the temperature in reflux extraction and the general leaching process of continuous circumfluence extraction method is all higher, how under the solvent fluidized state, to carry out, thereby tend to cause the thermal sensitivity active ingredient in the plant to be extracted to lose in a large number when extracting under for a long time boiling condition, have a strong impact on the product special flavour quality; And the present invention does not heat when extracting.The extract temperature generally all remains on 40～50 ℃, thereby the loss of thermal sensitivity active ingredient is few, and how of fine quality the products obtained therefrom amount is.For example, adopt the present invention that the root of large-flowered skullcap is extracted approximately 10min after, the yield of scutelloside than decocting method extract 3 hours taller, and on compound structure without any impact.4, practical value is high, is highly suitable for large-scale industrial production, is conducive to apply.In sum, the present invention is saving of work and time and can obviously improve the quality of products and the product yield both, extracts not only that required time is short, extraction efficiency is high, and the leaching process temperature is low, need not heat, when having avoided high-temperature heating to the destruction of active ingredient.
