Ukukhiqizwa kwe-gelatin kuqala ngemikhiqizo ephuma ezilwaneni (izikhumba, amathambo, imisipha), ehlanzwa, isuswe amafutha, futhi ichotshozwe. Izikhumba zezingulube (30-50% collagen) namathambo ezinkomo yizona ezivame kakhulu. Izinto zokusetshenziswa ziyahlolwa ukuqinisekisa ukuthi azinazo izifo noma izinto ezingcolisayo, okuyisinyathelo esibalulekile se-gelatin yokudla/yemithi.​

I-Gelatin evela ezintweni zezilwane ezingacutshungulwanga kahle ingase ithwale izinto ezingcolisayo: izinsimbi ezisindayo ezivela ezindaweni zezimboni, ama-antibiotic avela emfuyweni, noma amagciwane afana ne-Salmonella. I-Bovine gelatin evela ezindaweni ezivame kakhulu i-BSE iphakamisa ukukhathazeka ngezifo ze-prion, yize ukutholakala okuqinile (isib. imithetho ye-EU) kunciphisa le ngozi. I-fish gelatin, yize iphephile, ingaba ne-mercury uma ivela emanzini angcolile.​

Umthelela ophawulekayo we-gelatin ukudala ukwakheka kwejeli okunokuguquguquka okuhlukahlukene. Kumaswidi e-gummy, ukugcwala kwe-gelatin okungu-10-15% kuveza ukuthungwa okuhlafunwayo, okugobhozayo. Ku-aspic, ukugcwala okuphansi (2-5%) kukhiqiza ijeli ethambile, enyakazayo ekhombisa izithako ezifana nemifino noma inyama. Izinga lokuncibilika kwejeli (25-35°C) liqinisekisa ukuthi ithambile emlonyeni, okuthuthukisa ukunambitha.

I-Gelatin iwumkhiqizo otholakala ngokuhlanza nokufutha i-collagen ezikhumbeni zezilwane, emathanjeni nasezicutshini ezimhlophe ezixhumeneyo. Izindlela ezivame ukusetshenziswa zokukhipha i-gelatin zifaka phakathi ukwelashwa nge-alkali, i-asidi, kanye ne-enzyme. Ukwenziwa kwe-gelatin kuhilela izinqubo ezintathu eziyinhloko: ukwelashwa kwangaphambili, ukukhishwa kwe-gelatin, kanye nokwelashwa ngemva kokwelashwa.
