Yintoni umahluko phakathi kwegelatin kunye ne-collagen?
- Inkcazo kunye nolwakhiwo
I-Gelatin yiproteni ephuma kwi-hydrolysis engaphelelanga ye i-collagen, iproteni enemicu eninzi kwizicwili ezidityanisiweyo zezilwanyana ezifana nolusu, amathambo kunye nemisipha. I-Collagen inesakhiwo esiqinileyo se-triple-helix esizinzileyo ziibhondi ze-hydrogen, nto leyo eyinika amandla aphezulu okutsala. Ngokwahlukileyo koko, isakhiwo se-gelatin yi-random coil eguquliweyo ngenxa yokuqhekeka kweebhondi ze-collagen ze-helical ngexesha lokucubungula, nto leyo eyivumela ukuba inyibilike emanzini ashushu kwaye yenze ii-gel xa zipholile.
- Inkqubo yokukhupha
I-Collagen Ukukhupha i-gelatin kufuna iindlela ezithambileyo zokugcina isakhiwo sayo sendalo, kusetyenziswa ii-enzymes okanye unyango lwe-asidi/i-alkaline oluphantsi kumaqondo obushushu aphantsi. Nangona kunjalo, ukuveliswa kwe-gelatin kubandakanya i-hydrolysis enamandla ngakumbi: izinto ezikrwada ziyabiliswa okanye ziphathwe ngee-asidi/i-alkali ezinamandla ukuze kwaphulwe iibhondi ze-peptide ze-collagen. Lo mahluko ekucutshungulweni uchaza isizathu sokuba i-collagen igcine ukuqina kwayo kwesakhiwo, ngelixa i-gelatin ifumana iipropati ze-gelling.
- Izicelo
I-Collagen ixatyiswa kakhulu kwizongezo zokuxhasa impilo yamalungu kunye nokuqina kolusu, njengoko ulwakhiwo lwayo lweemolekyuli lungasinda ekugayweni ngcono. Ukuguquguquka kwe-Gelatin kuyabonakala isithako sokutya(iijeli, iimarshmallows), amayeza (iikhaphu), kunye nezinto zokuthambisa (iikhrimu), apho ubuchule bayo bokwenza ijeli, ukuqina, kunye nokwenza ifilimu bubaluleke kakhulu. Ngokungafaniyo ne-collagen, ulwakhiwo lwe-gelatin oluguqulweyo lwenza kube lula ukuyifaka kwiifomyula ezahlukeneyo.
