Description

Utilize membrane separation technique from octopus residue, to extract the method for natural taurine
Technical field
The present invention relates to a kind of natural taurine extracting method, especially relate to a kind of method of utilizing membrane separation technique from octopus residue, to extract natural taurine.
Background technology
Taurine (Taurine) is a kind of sulfur-bearing nonprotein amino acid, chemistry 2-aminoethyl sulfonic acid by name, and molecular formula is C 2H 7NO 3S, structural formula are H 2N-CH 2-CH 2-SO 3H, it is one of major ingredient of rare medicinal herbs ox sulphur, extensively has been applied in industries such as food and medicine effectively.
Octopus is commonly called as eight band octopus, has 142 kinds at least, and China is one of its main place of production.Octopus is the high fishery products of natural taurine content in the food; reach 31.2 μ mol/g; be equivalent to 390mg/100g and (see document: Chen Yuzhen; content of taurine in the food, amino acid and Biological resources (J), 1994; 4); the true chapter that content is high [octopus vulgaris] competes to reach 1000mg.up/100g, and internal organ contain taurine also up to 1030mg/100g, and it is that content of taurine is one of the highest in all fishery products.
Existing octopus is difficult to the controlling microbial index because of being subjected to condition restriction such as processing technology and processing units, and nutrition runs off serious, and color is inharmonious, and converted products is difficult to be accepted by the human consumer.Therefore generally be difficult to cause added value of product low to its deep processing.Tankage such as the internal organ that produced in precision work octopus process, tail point, eye socket and back saliva body of gland account for 30% of raw material, owing to be subjected to the restriction of technology and equipment condition, generally all that these tankage are discarded in vain, can't make full use of, not only waste resource but also contaminate environment, caused the big public hazards of one on the aquatic products processing industry.The most methods of synthetic that adopt of existing taurine obtain, and especially obtain common every kilogram only 60~80 yuan of its product by chemical synthesis process.Publication number be the application for a patent for invention of CN1626511A to disclose a kind of be that raw material adopts circulation method to prepare taurine with the thanomin, it remains a kind of bioactive taurine that do not possess, and is worth low.
Summary of the invention
The present invention is in order to overcome problems such as the wastings of resources that tankage caused such as having the internal organ that produced, tail point, eye socket, back hypophysis now in processing octopus process and environmental pollution; a kind of method of utilizing membrane separation technique to extract natural taurine from octopus residue is provided; than chemical extraction method have simple to operate, speed fast, be worth high and do not produce advantage such as pollution, reached the purpose that turns waste into wealth.
Step of the present invention is as follows:
1) raw materials pretreatment: the tankage that will process in the octopus process to be produced comprise that raw materials such as internal organ, tail point, eye socket, back hypophysis concentrate the back to extract ink sac earlier, remove the pollutents such as internal organ of foul smell, and it is cleaned up;
2) preparation slurries: slurries are made in dilution after the tankage fragmentation that cleans up;
3) solid-liquid separation: with the slurries solid-liquid separation, the supernatant feed liquid changes next procedure over to, and solid materials can be used as feedstuff raw material and handles;
4) one-level ultrafiltration: with the supernatant feed liquid as raw material, adopt the ultrafiltration membrance filter device to carry out separating clarifying, get clear liquor and concentrated solution, its molecular weight cut-off is 30000~50000, clear liquor changes next step over to, and concentrated solution mixes the solid materials of previous step in rapid and handles as feedstuff raw material together;
5) two-stage ultrafiltering: clear liquor as raw material, is adopted the two-stage ultrafiltering membrane separation unit, carry out separating and filtering once more, get ultra filtering clarifying liquid, its molecular weight cut-off is 2500~3500, and purpose is to remove the foreign protein in the raw material, with the quality of abundant assurance product;
6) reverse osmosis concentration: adopt the coiled reverse osmosis membrane assembly to concentrate ultra filtering clarifying liquid, get reverse osmosis concentrated liquid and penetrating fluid, reverse osmosis concentrated liquid is taurine and amino acid whose mixed solution, and spissated working pressure is 30~40kg/cm 2, cycles of concentration is 3~5 times, penetrating fluid is recyclable to step 5) and 6) and de-salted water collection continuation circulating filtration use as a supplement, reverse osmosis concentrated liquid enters next step;
7) resin absorption purifying: adopt ion exchange adsorption that reverse osmosis concentrated liquid is separated into taurine and amino acid solution, the amino acid solution that is produced is the canned nutritious prod of making directly, and fat is carried taurine and changed next step over to;
8) ethanol sedimentation: the taurine of resin absorption carries out wash-out with de-salted water, and the elutriant of collecting gained adds dehydrated alcohol, can obtain the taurine suspension liquid;
9) crystallization, purifying: above taurine suspension liquid is distilled, spraying, drying treatment reclaims ethanol, and obtains the bar-shaped natural taurine xln of high purity.
In step 2) in, will adding 8~10 times after the tankage fragmentation that clean up, the de-salted water (ion-exchange does not have the pure water of salinity) that is preferably 10 times allows its dilution make slurries.
In step 3), with step 2) slurries of gained with the whizzer partition method with solid-liquid separation.
In step 4), described molecular weight cut-off is preferably 40000, preferably adds de-salted water in clarifying process, sees through so that the composition in the stock liquid fully separates.
In step 5), described molecular weight cut-off is preferably 3000.
In step 6), because ultra filtering clarifying liquid volume is very big, to handle if directly carry out purified crystals, its energy consumption and loss amount are all bigger, and it is very necessary therefore reducing the crystallization material liquid volume as far as possible; Adopt the coiled reverse osmosis membrane assembly to concentrate ultra filtering clarifying liquid, get concentrated solution and penetrating fluid, spissated working pressure is preferably 35kg/cm 2, it is both economical that cycles of concentration is preferably 4 times of left and right sides.
In step 7); because the concentrated solution of gained is taurine and amino acid whose mixed solution; for obtaining simple taurine; must adopt ion exchange adsorption that taurine is separated with amino acid; ion-exchange absorption part is preferably proper with three series connection; each exchange bed diameter is preferably 500~600mm, and the amino acid solution that it produced is the canned nutritious prod of making directly, and fat is carried taurine and changed down the road step over to and carry out precipitated crystal.
In step 8), the taurine of resin absorption carries out wash-out with de-salted water, and the elutriant of collecting gained preferably adds 3 times dehydrated alcohol.
In step 9), the taurine suspension liquid is directly entered vacuum-evaporator distill spray drying treatment.
Technological operation speed of the present invention is fast, efficient height, but continuous production, but the same day, tankage disposed the same day, in time handled the waste material that enterprise is produced in processing octopus process.Both avoid environmental pollution, and can economize on resources again, turn waste into wealth, obtained the very high natural taurine of added value.At present; the natural taurine export price per kilogram of the biologically active that extracts with embrane method is up to USD300~3500; 2700 yuan of the about per kilograms of folding Renminbi; especially natural taurine and bile salt bound energy play vessel softening in the octopus; the effect of reducing cholesterol and blood pressure, it will bring glad tidings to the hyperpietic.
