Compared with available processes, the present invention has the advantages of simple operation, short extraction period, low power consumption, low extraction cost, high effective component transferring rate, etc.
Description
Technical field
The present invention relates to a kind of is raw material to contain albumen with fatty yolk powder, extracts the method for effective active composition, specifically relates to a kind of method of utilizing ultrasound-enhanced extractive technique to extract Ovum Gallus domesticus Flavus lecithin from yolk powder.
Background technology
Yelkin TTS is that a class mainly is made up of phosphatidylcholine (PC), phosphatidylethanolamine (PE), sphingomyelin (SM), lipositol, silk phosphatide and phosphatidic acid etc., and have the important substance of obvious physiologically active, be widely used in fields such as medicine, food, chemical industry, light industry at present.Yelkin TTS is except that a small amount of synthetic, and main source is to extract to obtain from natural phant or animal powdered egg, as soybean phospholipid that extracts from soybean or the egg phospholipids that extraction obtains from yolk.
External and the clinical study of having carried out both at home and abroad proves, Yelkin TTS energy dissolving cholesterol and triglyceride level, keep unobstructed blood vessel, effective preventing hypertension, hyperlipidemia and multiple cardiovascular and cerebrovascular disease, can directly enter by hemato encephalic barrier again and participate in the synthetic of neurotransmitter acetylcholine in the brain, play brain.Simultaneously, because existing hydrophilic radical in the lecithin molecules has oil loving group again, be the naturally occurring emulsifying agent of stable performance, safety, because its applied range, the Ovum Gallus domesticus Flavus lecithin demand is growing.Therefore, research and development Ovum Gallus domesticus Flavus lecithin preparation technology and realize that its industrialization is a crucial research topic, has remarkable economical meaning and social effect.
Ovum Gallus domesticus Flavus lecithin mainly contains solvent-extraction process and supercritical CO at present on extraction process
2Extraction process.The extraction solvent that traditional solvent relates generally to has alkanes, acetone, dme, C
1～C
3The binary system of Fatty Alcohol(C12-C14 and C12-C18) or Fatty Alcohol(C12-C14 and C12-C18) and alkane, ubiquitous problem are that the organic solvent consumption is big, the process time is long, extract yield Yelkin TTS is on the low side etc., are unfavorable for the suitability for industrialized production of product." Gansu Agriculture University,'s journal " 2003 the 38th the 3rd phases of volume " optimum process condition of extraction Yelkin TTS in the egg yolk " disclose and have adopted organic solvent to extract the operational path of Yelkin TTS from yolk, use earlier the analytical pure acetone deoiling, resulting throw out is used 99.7% extraction using alcohol again, and extracting solution is concentrated, is drying to obtain product.This technology is not only had relatively high expectations to solvent, and last resulting phosphatide yield is on the low side only to be 19.216%.
Supercritical carbon dioxide extraction method can be from yolk powder the higher Ovum Gallus domesticus Flavus lecithin of dna purity.The CN1056375C patent disclosure a kind of method of from yolk powder, extracting Ovum Gallus domesticus Flavus lecithin with supercritical co, this method can be isolated Oil of egg yolk and Ovum Gallus domesticus Flavus lecithin, but extraction time length is 3～4hr, working pressure is at 16～26MPa, there are problems such as facility investment is big, maintenance cost is high, production cost is higher, make commercial application be subjected to certain restriction.
In order to overcome the shortcoming of above-mentioned two kinds of extracting method, be necessary to grope a kind of new method for preparing Ovum Gallus domesticus Flavus lecithin.
Summary of the invention
The objective of the invention is from yolk powder, to extract Ovum Gallus domesticus Flavus lecithin, improve Yelkin TTS extraction yield in the yolk powder, simplify production technique, reduce production costs.
In order to reach the used technical scheme of goal of the invention be: with yolk powder is that raw material adopts the method for ultrasound-enhanced extraction to extract Ovum Gallus domesticus Flavus lecithin from yolk powder, be about to yolk powder and place the supersound extraction container, the ethanolic soln of adding 80～99%, ultrasound-enhanced extraction is 1～3 time under the whipped state, add ethanolic soln cumulative volume be 3～20 times of yolk powder weight, its ultrasonic frequency is 20～150KHz, extracting temperature is 20～70 ℃, each extraction time is 0.1～1hr, material after the supersound extraction is through centrifugal or filtration, clear liquid obtains Ovum Gallus domesticus Flavus lecithin through concentrating under reduced pressure and drying.
During concrete operations can be get clear liquid 40 ℃～45 ℃ of temperature, vacuum tightness-0.085MPa～-be evaporated to thick paste under the 0.095MPa condition, reclaim solvent, resulting paste in 55 ℃～60 ℃ of temperature, vacuum tightness-0.085MPa～-the 0.095MPa condition under drying under reduced pressure, promptly get light yellow Ovum Gallus domesticus Flavus lecithin.
Through the preferred processing condition of experimental study repeatedly be add ethanolic soln volume be preferably 6～15 times of yolk powder weight; Ultrasonic frequency during supersound extraction is 20～70KHz, and extracting temperature is 25～45 ℃, and each extraction time is 15min～40min; The pattern that supersound extraction adopted is that probe type ultrasonic or cleaning type are ultrasonic.
Patent of the present invention has overcome the deficiency of traditional solvent and supercritical carbon dioxide extraction Ovum Gallus domesticus Flavus lecithin technology.Because supersound extraction is to utilize multiple-effects such as ultrasonic cavitation effect, mechanical shock, heat effect, the High Temperature High Pressure field that moment produces in fluid, solid surface in the convection cell produces powerful shearing force, quicken the stripping and the reinforcing mass transfer process of active skull cap components, promote the mass transfer that extracts composition to separate, thereby shorten extraction time, improve extraction efficiency.This patent adopts ultrasound-enhanced extractive technique to extract Yelkin TTS from yolk powder and compares with existing method, have easy and simple to handle, extraction time is short, production energy consumption is low, extraction cost is low, the rate of transform height of effective constituent, production process safely, be easy to the advantage of aspects such as suitability for industrialized production.
Ultrasound-enhanced extractive technique is to strengthen under the leaching process at low-temperature physics to carry out resulting product purity height, good stability.Biological activity keeps intact, has kept the natural radioactivity and the trophic function characteristic of Ovum Gallus domesticus Flavus lecithin to greatest extent, meets the requirement of present people to the natural nutrition health functional food.
