Abstract
The present invention provides a method for continuously extracting egg oil and egg lecithin by utilizing supercritical CO2, which relates to a method for continuously extracting egg oil and lecithin. The continuous extracting process comprises: cooled CO2 is continuously supplied into an extracting kettle, the temperature in the extracting kettle is controlled to be within the range between 32 DEG C and 45 DEG C, and the pressure is controlled to be within the range between 16Mpa and 26MPa; egg oil is extracted ten minutes later, and 70 to 90% of egg oil is extracted 100 minutes later; an entrainer pump is utilized to pump entrainers into the extracting kettle, egg lecithin is extracted 10 minutes later, and 65 to 95% of egg lecithin is extracted 100 minutes later; when extracted, the egg oil and the egg lecithin simultaneously enter a separating kettle together with CO2, and then, finished products of egg oil and egg lecithin can be separated. The obtained product of the present invention has high quality and great economic value, the extraction is carried out under low pressure, and residual egg powder can still be processed and used, so that the product has bright prospects of industrialized production.
Description
Technical field: the present invention relates to a kind of continuous extration method to egg oil and egg yolk lecithin.
Background technology: main component has triglycerides, a spot of free fatty, pigment etc. in the egg oil.The yolk triglycerides is human important nutriment, can produce a large amount of heats when the body metabolism oxidation.Because it is similar to human milk that the aliphatic acid of egg oil is formed, therefore be used as the base oil in the infant formula.It also can be used as the assistant agent of the full Liposyn of the high nutrition of urgent patient, and patients ' recovery is played a significant role with earning a bare living.In addition, egg oil also has effects such as anti-inflammatory, treatment scald.Egg yolk lecithin has become very universal nutritional health food in developed country, in many countries, egg yolk lecithin has become a kind of nutritious supplementary pharmaceutical as vitamin, even as appetizing food, it is described as " greatest nutritionist ", " natural blood purificant ".The major function of egg yolk lecithin has: (1), can improve brain, nervous function.Egg yolk lecithin contains the predecessor " choline " and the acetyl coenzyme A of transmitter substance " acetylcholine ", it is prominent flourishing rapidly that the acetyl choline content increase can make cerebral nerve touch, quicken the brain nervous cell information transmission speed, help to improve brain activity, strengthen memory.(2), egg yolk lecithin can improve serum lipid metabolism, angiocardiopathy preventing.(3), prevention of arterial sclerosis.(4), improve the liver lipidosis.At present, the development of China's egg yolk lecithin is also quite backward, output, process equipment, technology, product function and kind etc. all can't satisfy domestic demand, high-quality egg yolk lecithin all relies on import, therefore very wide before the domestic market, potentiality to be exploited will be very considerable, press for develop a kind of extract high-purity egg yolk lecithin fast, economy and the compliance with environmental protection requirements extracting method of producing.The traditional extraction egg oil and the method for egg yolk lecithin are generally used organic solvent method, and the egg oil of acquisition and egg yolk lecithin product not only have organic solvent residual, and contaminated environment.Supercritical liquid extraction technique is a kind of novel separation and extraction technology that development in recent years is got up, and applying of it is an important directions studying the separating substances method from now on.
Summary of the invention: the object of the present invention is to provide a kind ofly can obtain purity height, the strong egg oil of stability and the continuous extration method of egg yolk lecithin, its extraction process is: at first extraction kettle is communicated with separating still, in extraction kettle, put into yolk powder, the CO of continual feeding more than 32 ℃, more than the pressure 7.3MPa
2, temperature in the kettle be will extract and 32～45 ℃, pressure 16～26MPa will be controlled at, promptly there is egg oil to be extracted out after 10 minutes, promptly there is 70～90% egg oil to be extracted out after 100 minutes; In extraction kettle, squeeze into the entrainer that accounts for residue yolk powder weight 5～15% then with the entrainer pump, promptly there is egg yolk lecithin to be extracted out after 10 minutes, promptly have 65～90% egg yolk lecithin to be extracted out after 100 minutes, egg oil and egg yolk lecithin are dissolved in supercritical CO when being extracted out
2And with CO
2Enter separating still, the temperature of separating still is controlled at 40～55 ℃, pressure is 6～9MPa, can successively isolate finished product egg oil and egg yolk lecithin.Utilize supercritical CO
2The continuous extraction technology is continuous extraction egg oil and egg yolk lecithin from yolk powder, the product purity height that obtains, and stability is strong, supercritical CO
2The continuous extraction technology is the leaching process that carries out egg oil and egg yolk lecithin under the cryogenic high pressure condition, it has avoided the oxidation of egg oil and egg yolk lecithin, keep the natural activity and the trophic function characteristic of egg oil and egg yolk lecithin to greatest extent, meet the requirement of present people the natural nutrition health functional food.The egg oil of gained of the present invention and egg yolk lecithin product quality are higher, have higher economic value, and the extraction process of test carries out under lower pressure, but the processing and utilization still of the yolk powder after the extraction residue, and the suitability for industrialized production prospect is considerable.
The specific embodiment one: in the supercritical extract process, determined the influence of extraction temperature, pressure, time, i.e. supercritical CO to extraction yield and purity
2The optimum process condition of extraction egg oil is: 32～45 ℃ of extraction temperature, pressure 16～26MPa, 100～250 minutes time.In order to determine preferable separation condition, temperature, the pressure of separating still are studied, determined supercritical CO
2The separation condition of extraction is 40～55 ℃ of separation temperatures, and pressure is 6～9MPa.Residue yolk powder behind the utilization extraction egg oil is proceeded supercritical CO
2Extraction egg yolk lecithin wherein, egg yolk lecithin is a polar substances, must add the polarity entrainer when the supercritical extract egg yolk lecithin, it could be extracted.Consider from the food security angle, can select for use ethanol to make entrainer, carry out the supercritical CO of egg yolk lecithin
2Extraction, the ethanol optimum addition is 5～15%, determines supercritical CO
2The optimum process condition of extraction egg yolk lecithin is: 32～45 ℃ of temperature, pressure 16～26MPa.
The continuous extraction process of present embodiment mesolecithal oil and egg yolk lecithin is: at first extraction kettle is communicated with separating still, puts into yolk powder in extraction kettle, the CO of continual feeding more than 32 ℃, more than the pressure 7.3MPa
2, temperature in the kettle be will extract and 32～45 ℃, pressure 16～26MPa will be controlled at, promptly there is egg oil to be extracted out after 10 minutes, promptly there is 70～90% egg oil to be extracted out after 100 minutes; In extraction kettle, squeeze into the entrainer that accounts for residue yolk powder weight 5～15% then with the entrainer pump, entrainer is an ethanol, promptly there is egg yolk lecithin to be extracted out after 10 minutes, promptly have 65～90% egg yolk lecithin to be extracted out after 100 minutes, egg oil and egg yolk lecithin are dissolved in supercritical CO when being extracted out
2And with CO
2Enter separating still, the temperature of separating still is controlled at 40～55 ℃, pressure is 6～9MPa, can successively isolate finished product egg oil and egg yolk lecithin.
