[invention field]
The present invention relates to a kind of plant milk extract, relate to the soybean extraction that contains Yelkin TTS and isoflavones particularly, and this preparation method of extract.
[background technology]
Soybean lecithin is one of nutrient substance that should replenish the every day of U.S. food and the nutrition council (being RDA) recommendation.Be referred to as by medical circle: the basic substance of life, the patron saint of cell, the street cleaner of blood vessel, the food of brain etc.Scientific research has been found that Yelkin TTS is the important component that constitutes cytolemma, and the keeping of existence, activation and organ function of human body cell played an important role.Yelkin TTS is hydrolyzed to glycerine, unsaturated fatty acids, choline and phosphoric acid at human body, and phosphate group wherein is hydrophilic, and fatty acid group is oil loving, these two kinds of groups make Yelkin TTS have emulsifying property, thereby can regulating blood fat, reduce blood cholesterol, the prevention cardiovascular and cerebrovascular diseases; Choline wherein enters that the back generates vagusstoff with intravital acetyl-CoA reaction in the body, and the vagusstoff important transmitter substance that is cerebral nerve, when this material increased in the brain, memory was strengthened, and the brain vigor also obviously improves.Phospholipids content is especially abundant in the soybean, and these phosphatide are compounding mixtures of multiple phosphatide such as Yelkin TTS, kephalin, lipositol, Val, serine phosphatide, sphingomyelin.Wherein the biology of Yelkin TTS phosphatidylcholine by name is called for short PC.The effect of soybean lecithin and function have obtained generally acknowledging of the whole world and have paid close attention to, and its function and preparation method's document and patent have had a large amount of reports and open.
Soybean is the abundant source of isoflavones (daidzein, tri hydroxy isoflavone).Soybean isoflavones is one of main plant class oestrogenic hormon, has weak estrogen-like effects.The estrogenic activity of soybean isoflavones only is 1/100 to 1/1000 of a natural estrogen, plays oestrogenic hormon and antiestrogenic dual regulation effect in vivo, and the women is had health-care effect preferably.Soybean isoflavones also has many biological activitys simultaneously, as: 1) antitumous effect: animal and in vitro tests prove, soybean isoflavones energy arrestin Tyrosylprotein kinase (cell signal changes different key enzyme), but anticancer growth; Dna replication dna be can suppress and necessary topoisomerase one type, two types transcribed; Can suppress vasculogenesis.The adjustable ganglion cell's of isoflavones cell cycle, differentiation and apoptosis.The antitumous effect of isoflavones is in some cancers relevant with hormone, and for example performances such as mammary cancer, the rectum cancer, prostate cancer are more outstanding.2) prevention coronary heart disease: isoflavones also is strong antioxidant, and it is oxidized that particularly the dihydroxy isoflavan can be protected low-density lipoprotein, helps anti-coronary heart disease; 3) preventing osteoporosis: decrease in estrogen, the absorption that influences calcium are that the postmenopausal women sends out major cause well osteoporotic, and the soybean flavonoid has estrogen-like effects, deficiency that can the added body inner estrogen; 4) alleviate or alleviate Woman climacteric symptom menopausal symptoms and also mainly descended by body inner estrogen level and cause, the soybean flavonoid can added body inner estrogen deficiency, improves menopausal symptoms.The soybean flavonoid is as one of the most famous protective foods, and its function and preparation method's document and patent have had a large amount of reports and open.
[summary of the invention]
This project provides a kind of application modern CO
2The mode of supercritical fluid extraction is extracted the extract that contains soybean lecithin and soybean flavonoid simultaneously, and this preparation method of extract is provided.This method has bigger improvement and simplification to the conventional art process route, and quality product improves a lot simultaneously.The present invention realizes above-mentioned purpose with following technical scheme.
Implementation method:
Present method is to utilize supercritical CO
2Abstraction technique directly extracts the novel method that contains Yelkin TTS and isoflavones two class active substances simultaneously in two steps from soyflour.The first step is at extracting pressure 10-25Mpa, under the extraction temperature 30-50 condition, extracts 2 hours, removes soybean oil and steroidal steroid material in the soyflour.Second step was the extraction slag of removing after the soybean oil, add 5% entrainment agent (food grade ethanol, Virahol etc.) circulation 30 minutes earlier, after making the fluid and extract thorough mixing that contains entrainment agent, entrainment agent is added to 10-25%, at extracting pressure 20-35Mpa, under the extraction temperature 40-60 condition, cycling extraction 4-6h, from separating still, emit extract, remove the solvent in the extract, promptly get the soybean extraction that contains Yelkin TTS and isoflavones simultaneously.
Compared with prior art, excellent benefit of the present invention is: do not see the report of producing the soybean extraction that contains two class active substance soybean lecithins and soybean flavonoid simultaneously with method of the present invention in the prior art.Prior art is mainly based on solvent-extraction process, the minority supercritical CO
2The grease in the soybean is also just removed in extraction, and does not directly extract phosphide and isoflavones, and complicated operation, industrial waste go thing many, the foreign matter content height, and final extract poor stability, and two class active substances are separately to prepare.And method service temperature of the present invention is low, can not make phosphatide heat damaging, good product quality; Because supercutical fluid has good mass-transfer performance, so the extraction efficiency height; Entire operation process safety is free from environmental pollution, and by single job, get final product the product soybean extraction, through efficient liquid phase chromatographic analysis, wherein Yelkin TTS (PC) content reaches more than 70%, and total isoflavone content reaches more than 8%, and color and luster is yellowish, no solvent residue, product impurity is few, and the activity substance content height does not contain cholesterol and triglyceride, meeting the demand of current green product development fully, is the good raw material of process for processing food, protective foods.The method for preparing product of the present invention is simple to operate, no trade effluent, waste, and safety, environmental protection have broad application prospects.
Further specify essentiality content of the present invention below in conjunction with test example of the present invention and embodiment, but content of the present invention is not limited thereto.
