Abstract
The invention refers to a making method of algae blue protein by using seawater spirulina as raw material. The current making method has long technical course, long cycle of extraction, high cost, low efficiency, low application value and mostly is made at low temperature. The invention can largely and at low cost extract higher-purity algae glue protein, is applied to research and development of natural pigment, health food and new sea medicament.
Description
Technical field
The present invention relates to a kind of is the preparation method that raw material extracts Phycocyanins, C-with the seawater spirulina.
Technical background
Seawater spirulina (Spirulina, seawater strain) be that Cyanophyta (Cyanophyta), section are grown the seawater cultivation strain that Cutleriales (Homogoneles), Oscillariaceae (Oscillatoniaceae), Spirullina (Spirulina) or artrospira spirulina belong to, China takes the lead in realizing the industrialization breed in the world.By the adaptation to the seawater stress condition, Phycocyanins, C-content, stability and biologic activity in the seawater spirulina are able to obvious raising.
The preparation method of the Phycocyanins, C-of being reported at present, all adopting the spirulina of the fresh water culture medium culturing gained of low salinity is raw material, does not see that useful seawater or artificial seawater are the report of substratum; The preparation method of existing Phycocyanins, C-in addition, see " Chinese science (C seizes) " the 30th volume, the frustule of being reported among the 5th phase PP449-454 is by the multigelation smudge cells, freezing high speed centrifugation method is carried out solid-liquid separation, ammonium sulfate precipitation, 0-4 ℃ of dialysis Shang chromatographic column, gradient elution repeatedly, the elutriant ammonium sulfate precipitation, 0-4 ℃ of dialysis, frozen drying etc., though can reach high purity, but operational path is long, most of process need be carried out at low temperatures, extracting cycle is about a week, thereby cost height, efficient is low, and production application is worth not high.
The objective of the invention is to cultivate spirulina,, be applied to the research and development of natural pigment, protective foods and marine drug as a large amount of, the low-cost Phycocyanins, C-s that extract higher degree of raw material by seawater.
Summary of the invention
Phycocyanins, C-product of the present invention, be with the Cyanophyta in the marine plant (Cyanophyta), section grow Cutleriales (Homogoneles), Oscillariaceae (Oscillatoniaceae), Spirullina (Spirulina) or
The seawater that artrospira spirulina belongs to is cultivated the algae of strain (seawater strain), frond through seawater acclimation and cultivation gained is a raw material, the blue protein ingredient of separation and Extraction gained, comprise two main ingredients of C-Phycocyanins, C-and Allophyxoxyanin, molecular weight is 30, and 000-40 is between 000 dalton, 620 and 652nm, wavelength place, product is the solid of sapphirine to the visible light maximum absorption band respectively.
Principal feature of the present invention is, the stimulation inducing action of different kinds of ions in seawater, it is very loose that the cell walls of seawater spirulina becomes and since the inside and outside osmotic pressure of cell than big-difference, cell walls is broken fast; Simultaneously, because the effect of seawater different kinds of ions makes the stability of Phycocyanins, C-improve, thereby can under comparatively high temps, extract Phycocyanins, C-; In addition, this process using the technologies such as " single stage method fast purifyings " of adding stablizer, ultrafiltration and concentration and directly soaking chromatographic material to extracting solution, the major part operation of whole technology can be carried out under comparatively high temps, because these characteristics, not only improved extraction efficiency, shorten process cycle (2-3 days) significantly, reduce extraction cost and can make product reach higher degree, thereby have higher production application value.Having not yet to see other process using seawater spirulina is the blue proteic report of material extraction algae.
Seawater spirulina involved in the present invention is meant algae in the Spirullina of fresh water culture medium culturing, get by seawater acclimation as spirulina plalensis (Spirulina platensis) or spirulina maxim arbitrary algae kinds such as (Spirulina maxima), its acclimation method is: by progressively increasing the salinity of SPIRULINA CULTIVATION base, tame with NaCl earlier, the each increasing degree of salinity is 3-5 ‰, after treating that the frustule growth is normal, add once more, until reaching natural sea-water salinity (30-35 ‰), progressively replace NaCl then with crude salt, and gradually reduce Ca, Mg, K ionic consumption, replace crude salt with natural sea-water at last, finish the seawater acclimation process and utilize this domestication process, can obtain adapting to the more seawater spirulina of high salinity (35-80 ‰).Seawater spirulina algae kind can be obtained from following unit: Chinese Academy of Science Nanhai Ocean Research Institute, the Institute of Oceanology of the Chinese Academy of Sciences, Fujian aquatic products institute, the 3rd institute of National Bureau of Oceanography, Florence, Italy university, Mexico university etc., seawater spirulina is finished industrialized culture by units such as Chinese Academy of Science Nanhai Ocean Research Institute, the 3rd institutes of National Bureau of Oceanography, and the algae powder can be made a big purchase acquisition in large quantities.Adopting seawater spirulina algae kind production Phycocyanins, C-and selenizing Phycocyanins, C-is one of most important characteristic of the present invention.
The preparation method of seawater spirulina Phycocyanins, C-of the present invention is:
(1) frond of gathering, flushing, drying.The seawater spirulina dry product is added in the aqueous solution of protection compositions such as containing edible stablizer (as salicylic acid, Sodium Benzoate, potassium sorbate), inorganic salts, carbohydrate, pH regulator agent.
(2) mixed solution stirs extraction under 0-50 ℃ of condition.Remove residue, get Phycocyanins, C-crude extract supernatant liquor.
(3) purifying of Phycocyanins, C-was undertaken by following A, two steps of B, carried out but A, B two go on foot transpose:
A. the crude extract supernatant liquor is after desalination and concentration by ultrafiltration, adopt " single stage method fast purifying " to remove Allophyxoxyanin and other foreign protein: promptly in extract, directly to add with 0.015-0.05M phosphate buffer solution (pH6-7, contain 0.1-0.5MNaCl) hydroxyapatite (chromatographic separation material) crossed of balance, make parameters such as the concentration of solution and pH that the C-Phycocyanins, C-is not adsorbed, stir, remove hydroxyapatite.
B. extracting solution adds the ammonium sulfate stirring, makes the Phycocyanins, C-salt precipitation.Centrifugal collection Phycocyanins, C-precipitation.The ultrafiltration desalination.
(4) the further ultrafiltration and concentration of gained desalting soln gets the Phycocyanins, C-liquid product; With concentrated solution frozen drying or spraying drying, get the Phycocyanins, C-solid articles.
In order to increase the stability of product, can add before the product drying safety non-toxic composition such as carbohydrate, salt as stablizer.Simultaneously, in order further to improve the purity of product, collected Phycocyanins, C-solution can continue to adopt the method for similar above-mentioned " single stage method fast purifying " that Phycocyanins, C-is carried out purifying after above-mentioned steps (3) was finished: directly add the hydroxyapatite of crossing with 0.001-0.01M phosphorus buffered soln balance and mix, remove supernatant liquor then, collect chromatographic material, adding the 0.015-0.05M phosphate buffer solution soaks, parameters such as the concentration of solution and pH just make selenizing C-Phycocyanins, C-dissolve in a large number, the purity of the Phycocyanins, C-of gained can near or reach the biochemical reagents standard.
Present method also can be used for the preparation of special ion enrichment Phycocyanins, C-, as selenizing Phycocyanins, C-, rich iron Phycocyanins, C-or rich zinc Phycocyanins, C-, these ions can be by adding their inorganic states composition in the seawater spirulina substratum, by the bioconcentration of spirulina in the culturing process, organically combine with Phycocyanins, C-.
