Description
The present invention is application number is 201310262059.3, and the applying date is on 06 27th, 2013, and denomination of invention is the divisional application that a kind of fish cartilage produces the patent of invention of the method for chondroitin sulfate coproduction Collagen Hydrolysate.
Technical field
The present invention relates to a kind of method that fish cartilage produces chondroitin sulfate coproduction Collagen Hydrolysate, belong to chemical technology field.
Background technology
Chondroitin sulfate (Chondroitin Sulfate is called for short CS) is the important acidic mucopolysaccharide of one being extracted preparation by the cartilaginous tissue such as bone, tracheae in animal larynx bone, nose.Chondroitin sulfate is distributed widely in people with some animals as in the tissues such as ox, sheep, pig, fish, and its main component is the mixture of the isomer such as chondroitin-4-suleate (CSA) and 6-chondroitin sulfate (CSC).Chondroitin sulfate is mainly used in treating cardiovascular and cerebrovascular disease, joint disease, and has reducing blood-fat, antithrombotic, the effect such as antitumor.China's chondroitin sulfate exports to the many countries of US and European in a large number, in the ten large class Chinese patent medicine raw materials that world market is badly in need of, occupy the 3rd.In recent years, chondroitin sulfate prevent and treat coronary heart disease, sacroiliitis and antitumor etc. in just day by day in widespread attention.
The method that current domestic chondroitin sulfate is produced mainly contains three kinds: salt solution, alkaline hydrolysis and enzymolysis process, the more method of domestic use be adopt diluted alkaline or concentrated base to combine with enzymolysis method to extract chondroitin sulfate, this alkaline process enzymolysis production process is adopted to there is complex steps, cycle longer, generally need 3-5 days, quality product and yield instability, in high temperature steaming, alkaline extraction, enzymolysis and decolorization, chondroitin sulfate is subject to havoc, product yield is on the low side, solution colour is deepened, alcohol consumption quantity is large, and production cost is high.
And a large amount of animal proteinum produced in current chondroitin sulfate production process and degraded product thereof all fail utilize and discharge, untreated organic waste water is pitch-black smelly, and eutrophication, severe contamination is brought to water surrounding.The relatively large chondroitin sulfate manufacturing enterprise of small part is only had to administer sewage at present, generally take simple physical chemistry to be treated to main end treatment mode more, afterbody process is all concentrated on by a large amount of protein pollutant, disposable input is larger, running expense is high, protein is not utilized, and waste discharge is difficult to realize up to standard.
Fish cartilage is the by product produced in China's processing of aquatic products process.Because the structure comparison of fish cartilage is loose, main component is mucopolysaccharide, protein and inorganic salt.Mucopolysaccharide alternately combines the assorted poly-polysaccharide of the acidity formed by hexosamine and hexuronic acid, and its main component is chondroitin sulfate.
Therefore consider the comprehensive utilization of fish cartilage, while production chondroitin sulfate, prepare protein powder, the added value of production can be increased, can environmental pollution be reduced again, but the current report having no this type of technology.
Summary of the invention
The present invention is in order to overcome the above-mentioned shortcoming existed in prior art, a kind of fish cartilage is provided to produce the method for chondroitin sulfate coproduction Collagen Hydrolysate, the synchronous production of chondroitin sulfate and protolysate in fish cartilage can be realized, utilize the chondroitin sulfate that production technique of the present invention is produced, purity reaches 95.6%, the protein content more than 92% of Collagen Hydrolysate, achieves the cleaning of fish cartilage, high-valued comprehensive utilization.
For achieving the above object, the technology used in the present invention solution is: a kind of fish cartilage produces the method for chondroitin sulfate coproduction Collagen Hydrolysate, and its step comprises:
One, pre-treatment: get the fresh fish-bone 3h that is soaked in water and to be placed in steam cooker 100
oc boils 30min, pulls the rear rejecting flesh of fish and grease out, rinses, be chopped into the bulk that size is 1cm × 1cm, weigh for subsequent use with clear water;
Two, enzymolysis: the aqueous solution that pretreated cartilage is added pH=8.5 by solid-liquid ratio 1:2, adds enzymic hydrolysis, constantly should remain on 8.0-8.5 by regulator solution pH in hydrolytic process;
Three, thermal treatment/filtering and concentrating: thermal treatment adds dilute hydrochloric acid or phosphoric acid adjustment solution ph in enzymolysis solution, and heating raised temperature, to solution layering, continues heating 30min, places and filter, remove non-hydrolytic acidity albumen, concentrated after solution layered filtration;
Four, resin absorption: through the continuous exchange adsorption of ion exchange resin after filtrate is concentrated, the feed liquid after exchange is protein hydrolysate and polysaccharide soln, through resin absorption after filtrate is concentrated, acetic acid-sodium acetate buffer solution wash-out, collects elutriant;
Five, POV chrondroitin: the analytical pure alcohol precipitation that elutriant adds 2 times of volumes after hydrogen peroxide for decoloration obtains chondroitin sulfate, and pelleting centrifugation is placed in thermostatic drying chamber, temperature control 60
oc is dry, and 4h obtains sterling chondroitin sulfate;
Six, reclaim albumen: the unconjugated hydrolysed protein soln after resin absorption is spray-dried, reclaim preparation protein hydrolysate powder.
Further, the judgement being hydrolyzed completeness in described step 2 is: get a little hydrolysis drop and add 50g/L Tricholroacetic Acid and observe solutions turbid degree and determine.
Further, the enzyme added in described step 2 is papoid, neutral protease and prozyme (FM), and adding proportion is 1:1:1 or 1:2:1 or 1:1:2.
Further, in described step 2, enzymolysis time is 2-6h, and hydrolysis temperature is 37-65
oc, enzyme dosage is 2-10g/kg.
Further, in described step 3, the temperature of enzymolysis postheat treatment is 70-90
oc, pH are 3.0-4.5.
Further, the resin adopted in resin absorption process in described step 6 is D001-cc resin, is loaded in 33 × 25cm chromatography columns, respectively with the acetic acid-sodium acetate buffer solution balance resin of pH6.0, pH5.0, pH4.0, identical with elutriant pH value to effluent liquid, balance completes.Loading wash-out: add above-mentioned chondroitin sulfate chromatographic solution 20mL respectively, after entering resin completely to chromatographic solution, with elutriant drip washing post jamb 2 times, then use the acetic acid-sodium acetate buffer solution wash-out of pH4.0, pH5.0, pH6.0 respectively, flow velocity 60mL/h, collect effluent liquid, added by ethanol in above-mentioned ion exchange chromatography liquid and reach 75% to ethanol content, chondroitin sulfate is separated out, filter, washing with alcohol 2 times, dries, obtains chondroitin sulfate sterling.
The invention has the beneficial effects as follows: 1, adopt combinative enzyme hydrolysis technology, realize the synchronous hydrolysis of chondroitin sulfate and collagen protein.By the collagen protein partial hydrolysis in fish cartilage while chondroitin sulfate is discharged.2, a large amount of protein pollutants produced by traditional chondroitin sulfate are recycled, and achieve the synchronous production of chondroitin sulfate and Collagen Hydrolysate, achieve the comprehensive utilization of fish cartilage, energy-saving and emission-reduction simultaneously, economic benefit and social benefit remarkable.
