Abstract
A process for extracting the polypeptide mixture from small marine fish includes protease enzymolysis, superfilter, ion exchange separation, eluting, concentrating, deposition and mixing. The resultant mixture used for health-care food or medicine to treat anemia contains protein (75%), free amino acids (15%), and polypeptide (50%).
Description
The present invention relates to a kind of method of from ocean fish, extracting the polypeptide mixture goods.
Small fish of marine products has a huge resource of catching in that China is coastal, at present to the utilization of this resource be mostly as the low price fish in the market direct marketing or directly become fish meal as feed ingredient as feed or roughing, its resource value is not fully utilized.
The objective of the invention is to propose a kind of big suitability for industrialized production that is suitable for, from small fish of marine products, extract the preparation method of polypeptide mixture goods.Realization improves its utilization of resources greatly and is worth the deep processing and utilization of small fish of marine products with huge resource.
The present invention with the small fish of marine products be preparation method that raw material extracts the polypeptide mixture goods comprise protease hydrolyzed, ultrafiltration, ion-exchange separate and concentrate, processing step such as precipitation, specifically:
The first step: enzymolysis
Fresh small fish of marine products is clean with tap water, deboner is got meat, pulverizes the adult fish gruel then.Get a fish gruel, add the deionized water of 1~5 times of weight in proportion, stirring is warming up to 50~70 ℃, weighs 0.5~3.0% ratio in fish again and adds proteolytic enzyme, is incubated to be warming up to 90~100 ℃ and keep some minutes after 1~5 hour rapidly.
Second step: ultrafiltration
The mixture that above-mentioned reaction finishes is centrifugal, and extracting centrifugal liquid is used the press filtration of middling speed filter paper again, collects filtrate, is the ultra-filtration membrane separation filtration of 10kDa~50kDa with the intercepting molecular weight, collects its filtration fraction.
The 3rd step: ion-exchange
Among the liquid of above-mentioned filtration fraction, add mixed phosphate, regulator solution is the buffer system of pH6~8, phosphatic concentration is 0.01~0.1M in the solution, dosage by 1.5~2.5 kilograms of every liter of liquid adds anionite-exchange resin, under room temperature, intermittently stirred 0.5~3 hour, centrifugal then, get centrifugate A.The dosage of pressing 300~500 milliliters of per kilogram resins again adds the phosphate buffer soln of 0.01~0.1M pH6~8, and is centrifugal after 0.5~1 hour with the mixed with resin stirring, gets centrifugate B.
The 4th step: concentrating and precipitating
A is mixed with B, and vacuum decompression is concentrated into 1/5~1/7 of original volume.Concentrated solution is cooled to 5~10 ℃, adds the cold acetone of 3~5 times of concentrated solution volumes again, stir fast, left standstill then 30~120 minutes, then in 4000 rev/mins centrifugal, taking precipitate is dry under vacuum-10 ℃~30 ℃ temperature, yellow powder powder solid I.
The 5th step: wash-out
The dosage of pressing 0.5~1.0 liter of per kilogram resin in above-mentioned resin after centrifugal adds elutriant, contains the NaCl of 0.1~0.4M in this elutriant, and adjust pH is 2~7, makes it have certain ionic strength and suitable pH value.Slowly stirred 1~5 hour under the room temperature, centrifugal then, get centrifugate C.Use dosage to add above-mentioned elutriant again by 300~500 milliliters of per kilogram resins, centrifugal after 0.5~1 hour with the mixed with resin stirring, get centrifugate D.
The 6th step: concentrating and precipitating
C and D are mixed, and vacuum decompression is concentrated into 1/8~1/10 of original volume.Concentrated solution is cooled to 5~10 ℃, removes by filter the salt crystal of being separated out, filtrate continuation is concentrated into 1/12~1/15 of original volume, is cooled to 5~10 ℃ and remove by filter the salt crystal of being separated out again, presses V then
2: V
1=3~5 volume adds cold acetone, left standstill 30~120 minutes behind the stirring and evenly mixing fast, then in 4000 rev/mins centrifugal, get be deposited under the vacuum-10 ℃~30 ℃ temperature dry, yellow powder powder solid II.
The 7th step: mix
Solid I and solid II are mixed promptly.
The present invention is extract obtained to be yellow powder powder solid, is dissolved in water and is the yellowish brown clear liquid.The total protein content of this product is greater than 75%, and wherein free aminoacid content is greater than 15%, and contained polypeptide mixture molecular weight is less than 50kDa, content of peptides greater than the polypeptide molecular weight more than 50%, 90% between 2k~8kDa.Product oral dosage every day 1~5g of the present invention can once take or part vic.Experimental results show that the effect that the polypeptide mixture of this method preparation has significant rising body oxyphorase and erythrocyte quantity.Can be used as nutritive health-care food and treatment for anemia medicine.The present invention can realize the science deep processing to resource small fish of marine products big, with low cost, and product economy is worth high, is suitable for suitability for industrialized production.
