Khoom Description
Dab tsi yog cov txheej txheem ntawm extract daim tawv nqaij collagen los ntawm ntses?
Kev Kho Mob Ua Ntej: Cov kauj ruam no yuav tshem tawm cov impurities xws li roj thiab heteroproteins los ntawm daim tawv nqaij ntses. Piv txwv li, anhydrous ether yog siv los ua degreasing reagent thiab kho rau 16 teev ntawm kev pub-rau-kua piv ntawm 1:80 (g / mL); los yog 0.6 mol-L^-1 Na2CO3 tov yog siv los tshem tawm heteroproteins los ntawm kev kho cov tawv nqaij ob zaug ntawm 25 degree rau 6 teev txhua zaus.
EXTRACTION: Raws li kev tshawb fawb sib txawv, muaj ntau txoj hauv kev rau kev rho tawm collagen, suav nrog alkaline, enzymatic, thiab ultrasound-pab enzymatic txoj kev. Piv txwv li, qhov zoo tshaj plaws rau cov alkaline extraction ntawm catfish tawv nqaij collagen rau cov khoom-kua piv ntawm 1:10, ntxiv 1.6% Ca (OH) 2, 70 degree rau 9 teev; enzyme extraction ntawm golden pomfret ntses daim tawv nqaij collagen rau qhov zoo tshaj plaws tej yam kev mob rau qhov sib ntxiv ntawm enzyme npaum li cas ntawm 1.5%, cov kua-piv piv ntawm 23: 1 mL / g, enzyme lub sij hawm ntawm 27.5 teev; Ultrasonic-assisted enzyme extraction ntawm mackerel ntses daim tawv nqaij collagen rau qhov pom kev mob rau qhov zoo tshaj plaws tej yam kev mob rau ultrasonic-pab enzymatic extraction ntawm mackerel daim tawv nqaij collagen yog 100 U / g ntawm enzyme, pH 7.5, enzyme digestion kub ntawm 40 degree, thiab kev kho mob ultrasonic lub sijhawm 50 min.
Purification: cov extracted collagen yuav tsum tau purification ntxiv kom tshem tau impurities. Piv txwv li, dextran gel kem chromatography yog siv los ntxiv purify cov extracted, salting tawm thiab decontaminated collagen.
Kev tsom xam thiab kev ua yam ntxwv: thaum kawg, cov extracted thiab purified collagen tau soj ntsuam thiab cov yam ntxwv los ntawm ntau yam kev tshuaj ntsuam xyuas (xws li, SDS-PAGE electrophoresis, ncig dichroism, lub sij hawm ntawm-flight mass spectrometry, thiab lwm yam) kom paub meej tias nws cov qauv thiab cov khoom. Piv txwv li, cov txiaj ntsig ntawm SDS-PAGE tau pom tias collagen muaj 1, 2 thiab chains, uas yog hom I collagen; lub sij hawm-ntawm-flight huab hwm coj spectrometry tau siv los txiav txim qhov ntau ntawm molecular loj faib ntawm hydrolyzate tau txais, thiab cov txiaj ntsig tau pom tias nws cov molecular loj yog cov concentrated hauv thaj tsam ntawm 0.6 kDa rau 1.8 kDa.
