Qhov sib txawv tseem ceeb ntawm collagen thiab gelatine yog collagen yog cov txheej txheem protein nyob hauv daim tawv nqaij thiab lwm cov ntaub so ntswg ntawm cov tsiaj thaum gelatine yog irreversibly hydrolyzed collagen.
Collagen yog cov protein ntau tshaj plaws hauv cov tsiaj. Yog li ntawd, nws muaj li ntawm 25 - 35% ntawm tag nrho lub cev proteins. Nws muaj ntau daim ntawv thov hauv tshuaj rau kev kho mob ntawm cov ntaub so ntswg. Gelatin yog ib qho tshuaj tua kab mob uas muaj ntau yam kev siv hauv kev lag luam khoom noj. Peb tuaj yeem tsim cov khoom sib xyaw no los ntawm collagen uas peb tau txais los ntawm lub cev ntawm cov tsiaj xws li nyuj, nqaij qaib, thiab npua uas yog domesticated.
YCollagen yog dab tsi?
Collagen yog cov txheej txheem tseem ceeb ntawm cov protein uas pom hauv daim tawv nqaij thiab lwm cov ntaub so ntswg. Nws kuj yog cov protein ntau tshaj plaws hauv cov tsiaj (25 - 35% ntawm lub cev protein). Tsis tas li ntawd, cov ntaub ntawv no ua rau kev sib xyaw ntawm cov amino acids. Peb tuaj yeem lees paub cov qauv tshuaj ntawm cov tshuaj no ua ib qho triple-helicase uas tsim cov elongated fibrils. Cov ntaub so ntswg ntau tshaj plaws ntawm peb lub cev uas peb tuaj yeem pom collagen yog nyob rau hauv cov ntaub so ntswg xws li tendons, ligaments, thiab tawv nqaij.
Daim duab 01: Triple Helix ntawm Collagen
Qhov ntawm collagen tuaj yeem ua nruj lossis ua raws. Tab sis qee zaum, nws yuav muaj qhov nruj kom ua raws li qhov nyob ntawm qhov degree ntawm mineralization. Piv txwv li: collagen yog nyob rau hauv daim ntawv nruj, nyob rau hauv cov pob txha, raws li nyob rau hauv tendons thiab nruab nrab ntawm pob txha mos. Ua cov txheej txheem protein, qhov sib xyaw no muaj ntau yam kev kho mob siv los kho cov pob txha thiab tawv nqaij. Nws yog dav siv nyob rau hauv daim ntawv purified rau kev kho kom zoo nkauj phais ib yam nkaus.
YGelatin yog dab tsi?
Gelatine yog cov zaub mov tsis muaj xim thiab translucent tau los ntawm collagen. Qhov sib xyaw no tau txais collagen los ntawm ntau lub cev ntawm cov tsiaj, xws li tawv nqaij, pob txha, cov ntaub so ntswg ntawm cov nyuj, nqaij qaib, npua, ntses, thiab lwm yam. Cov khoom no yog nkig thaum qhuav. Peb tuaj yeem tsim cov khoom sib xyaw no los ntawm irreversible hydrolysis ntawm collagen. Nws muaj ntau yam siv hauv kev lag luam khoom noj khoom haus raws li tus neeg sawv cev jelling thiab tseem nyob hauv kev lag luam kws tshuaj rau kev tsim tshuaj. Ntxiv mus, nws muaj txiaj ntsig zoo hauv kev yees duab, hauv kev tsim cov tshuaj vitamin capsules thiab hauv kev tsim tshuaj pleev ib ce zoo li.
Daim duab 02: Gelatin muaj txiaj ntsig zoo li Jelling Agent hauv Kev Tsim Khoom Noj
Cov tshuaj no muaj cov proteins thiab peptides. Cov proteins thiab peptides no hydrolyze ib nrab los ua gelatin. Nyob ntawd, lub ntuj molecular bonds ntawm collagen strands tau tawg mus rau rearrange, tsim gelatine. Cov tshuaj no muaj nyob hauv cov hmoov qhuav hauv khw. Nws yooj yim yaj nyob rau hauv dej kub / boiling dej thiab teem los ua ib tug gel thaum txias. Tab sis yog tias peb yaj nws hauv dej txias, nws tsis yaj ntau.
Ntxiv rau, qhov sib xyaw no dissolves hauv ntau cov kuab tshuaj polar. Thaum yaj, nws yog cov kua viscoelastic heev. Nws yog ib tus neeg muag khoom zoo tshaj plaws hauv kev ua noj ua haus. Tsis tas li ntawd, cov cuab yeej ua yeeb yaj kiab kuj tseem siv cov khoom siv no ua cov xim gels los hloov cov xim ntawm cov nqaj. Tsis tas li ntawd, cov tshuaj pleev ib ce kuj muaj cov tshuaj no nyob rau hauv lub npe "hydrolyzed collagen".
Qhov txawv ntawm Collagen thiab Gelatin yog dab tsi?
Collagen yog cov txheej txheem tseem ceeb ntawm cov protein uas pom hauv daim tawv nqaij thiab lwm cov ntaub so ntswg. Nws yog ib tug natural tshwm sim protein. Qhov no compound muaj ib tug triple-helical qauv uas tsim elongated fibrils. Gelatin yog ib qho khoom noj tsis muaj xim thiab translucent tau los ntawm collagen. Peb tuaj yeem tsim cov khoom sib xyaw no los ntawm collagen ntawm irreversible hydrolysis. Tsis tas li ntawd, nws tsim los ntawm kev rhuav tshem thiab rov kho cov molecular bonds ntawm cov protein thiab peptides ntawm collagen. Qhov no yog qhov txawv ntawm collagen thiab gelatin.
Summary – Collagen vs Gelatine
Collagen yog protein. nws muaj ntau yam kev siv tshuaj los kho cov teeb meem ntawm lub cev vim nws yog cov qauv tseem ceeb ntawm peb cov ntaub so ntswg. Gelatin, ntawm qhov tod tes, yog ib yam khoom uas peb tuaj yeem tsim los ntawm collagen. Qhov sib txawv ntawm collagen thiab gelatine yog tias collagen yog cov txheej txheem protein nyob hauv daim tawv nqaij thiab lwm cov ntaub so ntswg ntawm cov tsiaj thaum gelatine yog irreversibly hydrolyzed collagen.
