Description

The method extracting collagen protein polypeptide coproduction chrondroitin from cattle cartilage
Technical field
The present invention relates to technical field of bioengineering.From cattle cartilage, collagen protein is extracted many more particularly, to one The method of peptide coproduction chrondroitin.
Background technology
Collagen protein polypeptide has the digestibility of height, except a small amount of in oral cavity, stomach near by the effect of protease Outside one step is decomposed, the oral human body that enters passes the oral cavity of people, stomach rapidly, is directly entered small intestinal, by intestinal absorption, eventually enters into Blood circulation of human body system, organ and cell tissue, play rapidly its physiological action and biological function.In the world to collagen egg White research conclusion, the number-average molecular weight of collagen protein is 2000~3000 when, most useful for absorption of human body.
The source of natural biological calcium such as ocean Concha Ostreaes etc., due to marine pollution matter, so having been reported that this kind of calcium preparation is deposited At element pollutions such as lead cadmiums.Concha Ostreae often contains each Heavy Metallic Elements, long-term taking can make these heavy metal depositions in Internal cause chronic poisoning.
Chrondroitin has been found to reach to supplement the effect of soft tissue of joint structure via being administered orally, and takes cartilage clinically Element can effectively alleviate arthritic pain and inflammation phenomenon, has the effect delaying joint ageing simultaneously.Deep by high-tech Processing, can treat nervous headache, trigeminal neuralgia, coronary heart diseases and angina pectoris, myocardial ischemia, cardiovascular and cerebrovascular disease, joint Bitterly, the disease such as atherosclerosis and hepatitis.Can there is enhancing human body constitution as the additive in health product, food and resist Pathogenic bacteria, beauty treatment, the anti-ageing effect of waiting for a long time.Now exporting to American-European multiple country, the market demand is vigorous.
Chrondroitin is prepared with salt solution, alkaline hydrolysis and enzymatic isolation method mostly by manufacturing enterprise now, and using more method is to adopt The method combined with enzymolysis with alkali extracts chrondroitin, uses this alkaline process enzymolysis production process to there is complex steps, cycle Longer, in high temperature steaming, alkaline extraction, repeatedly enzymolysis and decolorization, chrondroitin is destroyed, and product yield is on the low side, produces Cost is high.
Accordingly, it is desirable to provide a kind of extract yield is high, and method is simple, the collagen protein polypeptide of mild condition, biological calcium, The co-production of chrondroitin.
Summary of the invention
It is an object of the invention to provide a kind of method extracting collagen protein polypeptide coproduction chrondroitin from cattle cartilage.Should The product purity that method process conditions are gentle, energy consumption is low, obtain is high, steady quality is reliable, it is achieved that cattle cartilage resource efficient Comprehensive utilization, it is achieved that the intensive processing of cattle cartilage and from cattle cartilage coproduction extract collagen protein polypeptide and chrondroitin, carry High cattle butchers the added value of by-product, and without newly polluting generation in production process, decreases the pollution to environment in all directions, Environmental protection.
For reaching above-mentioned purpose, the present invention uses following technical proposals:
The method extracting collagen protein polypeptide coproduction chrondroitin from cattle cartilage, comprises the steps:
