Abstract
The present invention relates to a method for extracting yolk lecithin from yolk by supercritical carbon dioxide. In the method, yolk lecithin with high purity can be extracted by a one-step method in ethanol with 95% of an added modifying agent at the controlled temperature of 50 to 60 DEG C and the pressure of 25 to-30*10<6> pascal for the extraction time of 2 hours. Compared with the existing two-step method mixing supercritical CO2 with chemical solvents, the method of the present invention is more convenient and has a smaller quantity of solvents contained in products.
Description
The present invention relates to a kind of method of extracting egg Yelkin TTS from yolk, particularly a kind of supercritical co extracts the method for Ovum Gallus domesticus Flavus lecithin from yolk.
As everyone knows, egg yolk lecithin is mainly as medicine, makeup and dietary supplements.Extract the method for egg yolk lecithin from yolk powder, at present industrialized is to adopt chemical solvents method and nearest report to use supercritical CO earlier
2Extract Oil of egg yolk, with dissolution with solvents lecithin wherein, steam the mixing Ji method of solvent at last again, residual in long a large amount of solvents of consumption of the former shortcoming technical process and the product have solvent up to 3000PPM, the latter also is that technology is numerous and diverse, also contains sunken the lacking such as solvent up to 2000PPM in the product.
The objective of the invention is to one a kind of supercritical CO is provided
2The method that adds properties-correcting agent one step extraction lecithin.The foundation of this method is can be by CO at the Oil of egg yolk of low-pole
2At first extract, add strong polar dissolve with ethanol lecithin wherein then at supercritical CO
2Down, lecithin is separated with ethanol, single stage method can be isolated pure protein powder, Oil of egg yolk to yolk powder and contain the pure Yelkin TTS of ethanol less than 3PPM simultaneously.
Embodiment of the present invention are as follows, yolk powder is placed start CO in the extraction kettle
2Pump, CO
2From bottom to top entering extraction kettle after the preheater preheating, is 50-60 ℃ in temperature, and pressure is 25-30 * 10
6Extraction is 2 hours under the MPa, the CO that has Oil of egg yolk, egg yolk lecithin, moisture content that comes out from extraction kettle
2Behind two separators, Oil of egg yolk and egg yolk lecithin are just stayed in No. 1 separator, and moisture content is emitted from No. 2 separators, CO
2After mole sieve drier purification and condenser condenses, return CO again
2Pump; Start the properties-correcting agent pump then and make CO
2Stream enters extraction kettle from top to down, at the constant CO down of temperature and pressure
2With the properties-correcting agent throughput ratio be 8: 2 times the extraction 2 hours after shut-down operation, can in extraction kettle, emit the pure protein powder, in No. 1 separator, emit pure Oil of egg yolk, in No. 2 separators, emit high-purity lecithin.
Following preference is described in detail but does not mean that the present invention in conjunction with the accompanying drawings and limits the scope of the invention.
Example 1: 6 kilograms of yolk powders are packed in 10 liters of collection stills (4), after extraction temperature reaches, start CO
2Pump (2) is opened stopping valve (11), (13), CO
2Stream reaches that Oil of egg yolk just is dissolved in the super CO that faces after the predetermined pressure from lower to upper
2, in through relief valve (15), (17) to separating still (5), (7), step-down step by step, Oil of egg yolk just is collected in separating still (5), moisture content is then stayed in the separating still (7), separating still (7) top CO
2Auto recycling after mole sieve drier (8) purifies, CO
2Down, start properties-correcting agent pump (1), stopping valve (12), close stopping valve (13) on the change stream is served as reasons behind the extraction Oil of egg yolk, open by (14), CO
2Flow into from top to bottom in the extraction kettle (4) with properties-correcting agent, make properties-correcting agent fully dissolve lecithin, and albumen is insoluble.Open stopping valve (16), (19) separate out lecithin in separating still (2), ethanol stays at separating still (3), extract between two hours after, close properties-correcting agent pump (1) and stopping valve (12), use pure CO
2Purge certain hour, to remove the lecithin residual ethanol.Stop CO after having extracted
2Extraction kettle (4) left by pump (2), gets 2.04 kilograms in pure protein powder, emits 2.68 kilograms of pure Oil of egg yolk in the separating still (1), must be from 0.99 kilogram of pure egg yolk lecithin in the separating still (2).
Example 2, remove temperature and change 58 ℃ into, pressure changes 28 * 10 into
6Outside the handkerchief, all the other conditions are identical with example 1, separate 2.21 kilograms in pure protein powder, 2.857 kilograms of pure Oil of egg yolk, 1.0 kilograms of pure egg yolk lecithins.The egg yolk lecithin of example 1 and example 2 gained records the content that phosphorus content calculates egg yolk lecithin by GB (GB-5537-85) and is all＞and 96%, contain amount of alcohol less than 3PPM.
Advantage of the present invention is to adopt overcritical one-step method to isolate the yolk ovum phosphorus of purity＞96% Ester contains amount of alcohol, and to contain quantity of solvent more than the prior art products obtained therefrom much smaller. Secondly easy and simple to handle, steady Fixed reliable.
