Abstract
The invention relates to a process of preparing lecithin with advanced shearing equipment, especially relates to a method for extracting yolk lecithin and soybean lecithin with alcohol. The invention employs alcohol as extracting agent, and disintegrates and extracts solid lecithin-containing material (such as dried egg yolk and powder soybean bean lecithin ) with advanced shearing equipment simultaneously, which greatly shortens extracting time, improves extraction rate, reduces solvent consumption and improves working condition.
Description
Technical field
The present invention relates to a kind of production technique of extracting Yelkin TTS, specially refer to extraction using alcohol yolk powder mesolecithal Yelkin TTS with the soybean lecithin in the extraction using alcohol powder soybean phospholipid.
Background technology
Be raw material all both at home and abroad at present, under agitation condition, leach the Yelkin TTS in the solid phase with ethanol with solid yolk powder and powder soybean phospholipid.Contained phosphatide (Phospholipid. in yolk powder and the powder soybean phospholipid, be called for short PL) be that phosphorous monoester mixes biology, mainly be by Yelkin TTS (phosphatidylcholine, Phosphatidylcholines are called for short PC), kephalin (phosphatidylethanolamine, Phosphatidylethanolamines, be called for short PE) lipositol (phosphatidylinositols, Phosphatidylserines are called for short PI) and serine phosphatide (phosphatidylserine, Phosphatidylinositols is called for short PS) etc. composition.Ethanol is to Yelkin TTS solubleness maximum, and kephalin takes second place, and the molten Jie's degree of other phosphatide is very little, so can extract contained Yelkin TTS in the solids with ethanol.The material that is extracted is called pure dissolubility phosphatide, its lecithin content can reach 50%～70% (PC50, PC70).Because phosphatide cpd all is heat-sensitive substances, after temperature surpasses 60 ℃, can decompose; With contain oxidation after oxygen contacts in the air, generate virose peralcohol, all under cryogenic nitrogen atmosphere, carry out so extract in the Yelkin TTS technology, to guarantee quality product at phosphatide.
Yolk powder and powder soybean phospholipid all are pressed powders, and wherein contained Yelkin TTS is all surrounded by other big quantity of material, are difficult to be diffused into the surface, so stirring extracting method of present utilization, extraction time was wanted more than 10 hours, have in addition want soaked overnight, extraction efficiency is very low; Because leaching process is a solid-liquid phased soln process,, need to reduce the middle mutually Yelkin TTS concentration of ethanol, again to improve the dissolved impellent with a large amount of ethanol in order to accelerate the Yelkin TTS dissolution rate.And repeated multiple times leaching just obtains certain extraction yield, thus cause equipment volume greatly, the ethanol consumption is big.
In order to accelerate the yield of above-mentioned solid-liquid leaching speed and Yelkin TTS, also report the method for adding inertia dispersion agent (as thin yellow ground, dextrin etc.) that adopt recently in the document as carrier.Concrete grammar is to dissolve all phosphatide earlier with normal hexane, add dispersion agent then, slough normal hexane more in a vacuum, like this in the dispersion agent surface, phosphatide forms the thin film of very thin thickness, leach with ethanol again, thereby the thickness of diffusion layer of minimizing Yelkin TTS is accelerated leaching speed and has been improved yield.Increased the precoated layer process but add the dispersion agent method, increased the impurity of post-processing difficulty and introduction dispersion agent, so this method is not adopted by actual production yet.
Summary of the invention
Purpose of the present invention is exactly a kind of method for preparing Yelkin TTS that provides a kind of in order to overcome the defective that above-mentioned prior art exists and can effectively shorten extraction time, cuts down the consumption of energy, improves the product extraction yield.
Purpose of the present invention can be achieved through the following technical solutions: a kind of method for preparing Yelkin TTS, it is characterized in that, this method adopts the high-shear extractor, with dehydrated alcohol the solids or the pressed powder that contain Yelkin TTS are efficiently pulverized and emulsification and extraction simultaneously, thereby so that very rapid rate and very high yield extract Yelkin TTS.
Described solids is a yolk powder.
Described pressed powder is a soybean phospholipid.
Described dehydrated alcohol and solids or pressed powder add in the extractor simultaneously, pulverize extraction and carry out synchronously, and the time is 10～15 minutes.
After the described pulverizing extraction, separate with the solid-liquid whizzer, the liquid phase vacuum promptly obtains lecithin product after taking off ethanol again.
But described vacuum is taken off the ethanol recirculation use that ethanol reclaims.
The present invention adopts High shear device, makes solid pulverize and extract and carries out simultaneously.Under powerful shearing force, ethanol carries out in the extraction process, and solid is ground into superfine powder, and this process has not only increased the specific surface area of leaching greatly, and has improved lecithin-diffused speed greatly; Whole leaching process can be finished at 10-15 minute, had howed soon than present traditional method.The entire operation process is carried out in the fully-closed nitrogen atmosphere, promptly guarantees quality product, has also reduced the alcoholic acid volatilization.
After ethanol leaching is finished, can enter and carry out solid-liquid separation in the whizzer, liquid phase is entering high-efficiency evaporator, ℃ takes off ethanol in vacuum＜60, and it is reusable to reclaim ethanol.Product behind the precipitation is lecithin product.Detailed process is seen accompanying drawing.
The present invention makes to pulverize and extract and carries out synchronously owing to adopt the high-shear extractor, has realized three big advantages of process innovation:
(1) adopts the high-shear extractor, make to pulverize and extract and carry out synchronously, shorten the time effectively, cut down the consumption of energy, improve the product extraction yield;
(2) reduce the organic solvent consumption of ethanol effectively, reduced potential safety hazard;
(3) equipment volume is little, entire equipment under nitrogen under the fully-closed protection, good product quality.
