Abstract
The invention relates to a novel production process for extracting soy isoflavones aglycones. The production process in the invention comprises the following steps of: smashing soy embryos or soy bean meal which serves as a raw material, extracting required ingredients, concentrating, removing proteins, performing column absorption and analysis, concentrating for the second time, performing enzymolysis, extracting a solvent, concentrating for the third time, freeze drying and obtaining the soy isoflavones aglycones. The novel production process for extracting the soy isoflavones aglycones is convenient to operate, high in repeatability and yield and suitable for industrial production; the enzymolysis method is adopted for converting the aglycones, so that the conversion rate is high and the process avoids using poison andharmful solvents; and electrolyte is used for settling the proteins, so that impurity removal is efficient and quick.
Description
Technical field
The invention belongs to natural product extraction technology, particularly a kind of production technique of novel extraction isoflavone genin.
Background technology
Soybean isoflavones is that the natural quality soybean is prepared from through the modern high technology means of purification, has strengthening immunity, anti-oxidant, function such as anti-aging, antibiotic in advance.At aspects such as the sickness rate that reduces the middle aged and aged women osteoporosis, elimination climacteric syndromes extraordinary effect is arranged.Multinomial studies show that, soybean isoflavones still are that the women prevents mammary cancer, the best health care nutriment of uterus carcinoma.Yet existing extractive technique is unsatisfactory, have that productive rate is low, complicated operation,, extract problems such as transformation efficiency is low, lyophilize weak effect.
Summary of the invention
In extracting the isoflavone genin process, there to be some unfavorable problems in order solving, to the invention provides a kind of production technique of novel extraction isoflavone genin, this invented technology productive rate height, simple operation, extraction transformation efficiency height from soy material.
Technical scheme of the present invention is: concrete composition of the present invention is daidzin, daidzin, Genistoside, daidzein, Daidzein, genistein.This invented technology step is:
(1) raw material is prepared: after soybean germ or bean cake powder essence to particle diameter are 0.5mm-5.0mm, standby;
(2) enzyme decomposes: add organized enzyme, controlled temperature is 40 ℃-50 ℃, and enzymolysis time is 24-72 hour;
(3) extract: with concentration is the alcohol reflux twice of 60%-80%, and solvent and raw material envelope-bulk to weight ratio are 5-10: 1, extract temperature at 70 ℃-100 ℃, alcohol reflux, extracting liquid filtering, united extraction liquid;
(4) vacuum concentration: extracting solution control vacuum tightness-more than the 0.80MPa, temperature obtains containing the one-level concentrated solution of alcohol concn about 5% at 50 ℃-70 ℃;
(5) deproteinated: the one-level concentrated solution adds CaCl
2Make the albumen rapid subsidence in ionogen, filter;
(6) absorption is resolved: the above-mentioned filtered liquid that obtains is transferred to macroporous resin column, and control absorption flow velocity washs decon with pure water then, resolves solvent with ethanol again and resolves, and obtains desorbed solution;
(7) secondary concentration: concentrate desorbed solution, obtaining desorbed solution, to contain alcohol concn be 2%, control vacuum tightness-more than the 0.80MPa, 50 ℃-70 ℃ of temperature obtain secondary concentration liquid;
(8) lyophilize: concentrated solution uses lyophilize, gets isoflavone genin.
The invention has the beneficial effects as follows: easy and simple to handle, the good reproducibility of production technique of the novel extraction isoflavone genin of this kind, the productive rate height, be applicable to suitability for industrialized production, adopt enzymolysis process to be converted into aglycon, the transformation efficiency height, technological process does not contain toxic solvent, and adopts ionogen sedimentation albumen, and dust removal rate is fast at a high speed.
