I-gelatin iveliswa njani?
Imveliso yegelatin iqala ngeemveliso zezilwanyana (izikhumba, amathambo, imisipha), ezicocwayo, zisuswe amafutha, kwaye zityunyuzwe. Izikhumba zeehagu (30–50% collagen) kunye namathambo eenkomo zezona zixhaphakileyo. Izinto eziluhlaza ziyahlolwa ukuqinisekisa ukuba azinazo izifo okanye izinto ezingcolisayo, inyathelo elibalulekileyo kwigelatin yokutya/yeyeza.
Ziziphi iingxaki zokhuseleko ezinxulumene ne-gelatin?
I-Gelatin evela kwizixhobo zezilwanyana ezingalungiswanga kakuhle inokuba nezinto ezingcolisayo: iintsimbi ezinzima ezivela kwiindawo zoshishino, ii-antibiotics ezivela kwimfuyo, okanye iintsholongwane ezifana neSalmonella. I-Bovine gelatin evela kwiindawo ezixhaphakileyo kwi-BSE iphakamisa iinkxalabo zesifo se-prion, nangona ukufumana ngokungqongqo (umz., imithetho ye-EU) kunciphisa le ngozi. I-fish gelatin, nangona ikhuselekile, inokuba ne-mercury ukuba ivela emanzini angcolileyo.
I-gelatin ichaphazela njani ubume bemveliso yokutya?
Eyona mpembelelo iphawulekayo yeGelatin kukudala ubume bejeli obunokuthamba okuhlukeneyo. Kwiilekese zegummy, ubuninzi bejelatin obuyi-10–15% buvelisa ubume oburhabaxa, obubuyela umva. Kwi-aspic, ubuninzi obuphantsi (2–5%) buvelisa ijeli ethambileyo, eshukumayo ebonisa izithako ezifana nemifuno okanye inyama. Indawo yokunyibilika kwejeli (25–35°C) iqinisekisa ukuba ithambile emlonyeni, nto leyo ephucula ukuncasa kwayo.

Yenziwa njani iGelatin? Iingcebiso ezine zokuguqula iCollagen ibe yiGelatin
IGelatin yimveliso efunyenwe ngokucoca kunye nokufaka i-hydrolyzing i-collagen kwiikhumba zezilwanyana, amathambo, kunye nezicubu ezimhlophe ezinxibelelanayo. Iindlela ezisetyenziswa kakhulu ekukhupheni i-gelatin ziquka unyango lwe-alkali, i-asidi, kunye ne-enzyme. Ukwenziwa kwe-gelatin kubandakanya iinkqubo ezintathu eziphambili: unyango lwangaphambi konyango, ukukhupha i-gelatin, kunye nonyango lwasemva konyango.
