Uyini umehluko phakathi kwe-gelatin ne-collagen?
- Incazelo kanye nesakhiwo
I-Gelatin iyiprotheni etholakala ku-hydrolysis engaphelele ye- i-collagen, iphrotheni enemicu eningi ezicutshini ezixhumene nezilwane njengesikhumba, amathambo, kanye nemisipha. I-Collagen inesakhiwo esiqinile se-triple-helix esiqiniswe yizibopho ze-hydrogen, esisinika amandla aphezulu okuthamba. Ngokuphambene nalokho, isakhiwo se-gelatin siyi-coil engahleliwe ephukile ngenxa yokuwohloka kwezibopho ze-collagen ze-helical ngesikhathi sokucubungula, okuvumela ukuthi incibilike emanzini ashisayo futhi yakhe ama-gel lapho ephola.
- Inqubo Yokukhipha
I-Collagen Ukukhipha kudinga izindlela ezithambile zokulondoloza isakhiwo sayo sendabuko, ngokuvamile kusetshenziswa ama-enzyme noma ukwelashwa kwe-acid/alkaline emnene emazingeni okushisa aphansi. Nokho, ukukhiqizwa kwe-gelatin kuhilela i-hydrolysis enamandla kakhulu: izinto zokusetshenziswa ziyabiliswa noma ziphathwe ngama-acid/alkali aqinile ukuze kuphulwe izibopho ze-peptide ze-collagen. Lo mehluko ekucutshungulweni uchaza ukuthi kungani i-collagen igcina ubuqotho bayo besakhiwo, kuyilapho i-gelatin ithola izakhiwo ze-gelling.
- Izicelo
I-Collagen iyigugu kakhulu ezithasiselweni zokusekela impilo yamalunga kanye nokuqina kwesikhumba, njengoba isakhiwo sayo sama-molecule sisinda ekugayweni kokudla okungcono. Ukuguquguquka kwe-Gelatin kuyabonakala isithako sokudla(amajeli, ama-marshmallow), imithi (ama-capsule), kanye nezimonyo (okhilimu), lapho ikhono layo lokugaya, ukuqina, kanye nokwenza ifilimu libaluleke kakhulu. Ngokungafani ne-collagen, isakhiwo se-gelatin esiguquliwe senza kube lula ukuyifaka ezinhlotsheni ezahlukene.
