Collagen peptide npaj cov tswv yim muaj xws li tshuaj txoj kev, enzymatic txoj kev, thermal degradation txoj kev thiab ib tug ua ke ntawm cov txheej txheem. Qhov hnyav molecular ntau yam ntawm collagen peptides npaj los ntawm ntau cov tswv yim sib txawv heev, nrog rau cov tshuaj thiab thermal degradation txoj kev feem ntau yog siv rau kev npaj ntawm gelatin thiab enzymatic txoj kev feem ntau yog siv rau kev npaj ntawm collagen peptides.
Thawj tiam: chemical hydrolysis method
Siv cov tawv nqaij thiab pob txha ua cov ntaub ntawv raw, collagen yog hydrolyzed rau hauv cov amino acids thiab me me peptides nyob rau hauv acid los yog alkaline tej yam kev mob, cov tshuaj tiv thaiv tej yam kev mob hnyav, cov amino acids raug mob hnyav thaum lub sij hawm tsim khoom, L-amino acids tau yooj yim hloov dua siab tshiab rau hauv D. -amino acids thiab tshuaj lom xws li chloropropanol yog tsim, thiab nws yog ib qho nyuaj rau kev tswj cov txheej txheem hydrolysis raws li cov txheej txheem ntawm hydrolysis, lub tshuab no tsis tshua muaj siv nyob rau hauv lub tshav pob ntawm collagen peptides.
Qhov thib ob tiam: biological enzymatic txoj kev
Siv cov tawv nqaij thiab pob txha ua cov ntaub ntawv raw, collagen yog hydrolyzed rau hauv me me peptides nyob rau hauv lub catalyst ntawm cov enzymes lom, cov tshuaj tiv thaiv mob yog mos thiab tsis muaj teeb meem by-products yog generated thaum lub sij hawm tsim cov txheej txheem, tab sis lub molecular hnyav ntawm hydrolyzed peptides muaj a ntau yam kev faib tawm thiab qhov hnyav molecular tsis sib xws. Txoj kev no tau siv ntau dua hauv kev npaj collagen peptide ua ntej 2010.
Peb tiam: biological enzymatic digestion + membrane cais txoj kev
Siv cov tawv nqaij thiab pob txha raws li cov ntaub ntawv raw, collagen yog hydrolyzed rau hauv me me peptides nyob rau hauv lub catalyst ntawm protein hydrolase, thiab ces lub molecular hnyav tis yog tswj los ntawm daim nyias nyias pom; cov tshuaj tiv thaiv mob me me, tsis muaj teeb meem los ntawm cov khoom tsim tawm thaum lub sijhawm tsim khoom, thiab cov khoom peptides muaj qhov nqaim molecular hnyav faib thiab tswj tau qhov hnyav molecular; cov tshuab no tau siv ib qho tom qab ib ncig ntawm 2015.
Plaub tiam: peptide npaj technology sib cais los ntawm collagen extraction thiab enzymatic txheej txheem
Raws li kev tshawb fawb ntawm thermal stability ntawm collagen, collagen yog muab rho tawm nyob ze ntawm qhov tseem ceeb thermal denaturation kub, thiab cov extracted collagen yog enzymatically zom los ntawm cov enzymes lom, thiab tom qab ntawd kev faib tawm ntawm molecular hnyav yog tswj los ntawm daim nyias nyias. Kev tswj qhov kub thiab txias tau siv los ua kom tiav cov txheej txheem collagen extraction invariance, txo qhov tshwm sim ntawm merad cov tshuaj tiv thaiv thiab inhibit qhov tsim ntawm cov xim xim. Cov tshuaj tiv thaiv mob me me, qhov hnyav molecular ntawm peptide yog qhov sib xws thiab qhov ntau yog tswj tau, thiab nws tuaj yeem txo cov tiam ntawm cov tshuaj tsis haum thiab inhibit qhov tsis hnov tsw, uas yog cov txheej txheem kev npaj collagen peptide tshaj plaws kom txog rau thaum 2019.
