Kupanga gelatin kumayamba ndi zinthu zochokera ku nyama (zikopa, mafupa, minyewa), zomwe zimatsukidwa, kuchotsedwa mafuta, ndikuphwanyidwa. Zikopa za nkhumba (30–50% collagen) ndi mafupa a ng'ombe ndizofala kwambiri. Zipangizo zopangira zimayesedwa kuti zitsimikizire kuti zilibe matenda kapena zodetsa, sitepe yofunika kwambiri pa gelatin ya chakudya/mankhwala.​

Gelatin yochokera ku zinthu zophikidwa bwino za nyama ikhoza kukhala ndi zinthu zodetsa: zitsulo zolemera zochokera kumadera a mafakitale, maantibayotiki ochokera ku ziweto, kapena tizilombo toyambitsa matenda monga Salmonella. Gelatin ya ng'ombe yochokera kumadera omwe ali ndi kachilombo ka BSE imabweretsa nkhawa za matenda a prion, ngakhale kuti kupeza zinthu mosamala (monga malamulo a EU) kumachepetsa chiopsezochi. Gelatin ya nsomba, ngakhale kuti ndi yotetezeka, ikhoza kukhala ndi mercury ngati imachokera ku madzi oipitsidwa.​

Chomwe chimapangitsa Gelatin kukhala yodziwika kwambiri ndikupanga mawonekedwe a gel okhala ndi kusinthasintha kosiyanasiyana. Mu maswiti a gummy, kuchuluka kwa gelatin 10–15% kumabweretsa mawonekedwe otafuna, obwerera m'mbuyo. Mu aspic, kuchuluka kochepa (2–5%) kumapanga gel yofewa, yogwedezeka yomwe imawonetsa zosakaniza monga ndiwo zamasamba kapena nyama. Kusungunuka kwa gel (25–35°C) kumatsimikizira kuti imafewa mkamwa, zomwe zimapangitsa kuti kukoma kumveke bwino.

Chochititsa chidwi kwambiri cha gelatin ndikupanga mawonekedwe a gel okhala ndi kusinthasintha kosiyanasiyana. Mu maswiti a gummy, kuchuluka kwa gelatin 10-15% kumabweretsa mawonekedwe otafuna, obwerera m'mbuyo. Mu aspic, kuchuluka kochepa (2-5%) kumapanga gel yofewa, yogwedezeka yomwe imawonetsa zosakaniza monga ndiwo zamasamba kapena nyama. Kusungunuka kwa gel (25-35°C) kumatsimikizira kuti imafewa mkamwa, zomwe zimapangitsa kuti kukoma kumveke.​

Gelatin ndi chinthu chomwe chimapezeka poyeretsa ndi kusakaniza kolajeni kuchokera ku zikopa za nyama, mafupa, ndi minofu yoyera yolumikizirana. Njira zomwe zimagwiritsidwa ntchito kwambiri pochotsa gelatin zimaphatikizapo mankhwala a alkali, asidi, ndi ma enzyme. Kupanga gelatin kumaphatikizapo njira zitatu zazikulu: chithandizo chisanachitike, kuchotsa gelatin, ndi chithandizo pambuyo pake.
