Description

A kind of method of from milk or whey water, extracting high purity protein
Technical field
The present invention relates to a kind of method of from milk or whey water, extracting high purity protein
Background technology
The present invention relates to a kind ofly from milk or whey water, extract highly purified lactoferrin (bovine lactoferrin simultaneously with stirred pot, be abbreviated as BLF), the method for Bovinelactoperoxidase (bovine lactoperoxidase is abbreviated as BLP) and lactoferrin and Bovinelactoperoxidase mixture.Bovinelactoperoxidase and lactoferrin have the antibiotic of wide spectrum, and be antiviral and improve the immunologic function of body disease-resistant.For example BLP can destroy the tenuigenin of germ, suppresses Yeast Nucleic Acid synthetic in the germ process of growth.Thereby it is to gram-positive microorganism and Gram-negative bacteria, yeast such as Candida albicans, and mould such as black-koji mould all have restraining effect.There is Bovinelactoperoxidase in the secretory product in the mammal, particularly in the milk.But its concentration is very low in first Ruzhong, and its concentration increases sharply and passes to the antibiotic of neonatal as parent after 4-5 days.Because the immune yarn system of neonatal is not physically well developed as yet, need from breast milk, be protected with germ and the virus that resists an invasion.
Bovinelactoferrin (BLF) is a ferruginous glycoprotein, and is opposite with Bovinelactoperoxidase, and it is dense colostrum, and its concentration just descends rapidly after several days.BLF also is a very antibacterial protein of wide spectrum.It can be robbed iron ion from germ, thereby germ mistake iron is suppressed or death.So BLF is to gram-positive microorganism such as streptococcus aureus, suis etc.; Gram-negative bacteria such as intestinal bacteria, dysentery bar mattress, and shiga bacillus; Hp, influenza virus, eczema virus and salivary gland virus all have restraining effect.
Because simple BLP and BLF have the proteic function of biological antibiotic, their two kinds of mixtures together also should have antibiotic, the function of antiviral and enhance immunity power.
The laboratory scale of existing report is isolated BLF, as uses DEAE, SephadexC50, CMSephaseFF, CMToyopear l, BioradMacro-preCM, Dowx-mac-3 and PuriliteC115 ion exchange resin.But these methods are resin to be adorned post use and adopt damping fluid.Such method is inapplicable large-scale industrial practice.Because BLF and the concentration of BLP in milk are very low, produce that commercial economy is worth, highly purified BLP and BLF must adopt the milk of huge amount so that enough BLF and BLP to be provided, such as will produce 20 kilograms of purity daily is 96% above BLF, suppose that its total recovery is 80%, the BLF in the raw material milk is 180mg/L.This just needs 160 tons of milk.And the treatment time of these 160 tons of milk must in 10 hours, finish, not only can increase the chance of milk microbiological contamination because consider long process period, and will set apart to ion exchange resin column regeneration and disinfecting to prepare second day work.Moreover, cause the absorption dynamics of BLF and BLP very slow because milk intermediate ion intensity is about 6-7mS (milli west door), needed 50 minutes just can reach more than 60% of total amount approximately.Therefore must give resin and milk has enough duration of contact.In order to make BLP as much as possible in the milk, BLF contacts the production permutoid reaction with resins exchange functional group simultaneously, must play the linear velocity that guarantees certain milk flowing, and in other words, linear velocity is big more in the post, and its resin absorption dynamics is just fast more.Such as the linear velocity in the post at least will 100cm per hour more than (1.6cm per minute), concerning the garden post that a diameter is 50cm, reach the linear velocity of 1.6cm per minute, its volumetric flow rate just at least will be at 3.2 Liter Per Minutes.If be no less than 50 minutes duration of contact, the length of post will be more than 83cm.But its column length surpasses 50cm when the diameter of post surpasses 30cm, just is difficult to guarantee the quality of its flow and dress post.Thereby above-mentioned these ion exchange resin are for laboratory scale designs, and do not possess the performance that still keeps high flow capacity under the technical scale condition, therefore can't be applied to the production process of scale like this.If moreover in separating the process of telling, adopt damping fluid, also increase production cost greatly, product can't be competed, this is worthless on industrial production especially.
Also have report to adopt ultra-filtration membrane to come from whey, to separate BLF, but the purity of the BLF that this method is produced is very low, only has an appointment about 30%.One of them possible factor is exactly that the molecular weight of BLP and BLF is very close, and the ultrafiltration membrane technique of present stage is impossible with these two kinds of albumen separately.
Have report to extract BLF, but because the iso-electric point of BLF and BLP is very close, this method can't be produced highly purified BLP and BLF with the isoelectric precipitation method.
Have report to use heparin agar affinity chromatography to extract BLF, but the production cost of this method is too high, can't realize technical scale.
Summary of the invention
Can not low cost carry out big industrial problem for solving the existing high purity protein technology of from milk or whey water, extracting.The invention provides a kind of method of from milk or whey water, extracting highly purified lactoferrin, Bovinelactoperoxidase and lactoferrin and Bovinelactoperoxidase mixture with stirred pot simultaneously.
