IBALI LEMBALI LEZIKHEPHU ZE-GELATIN
Okokuqala, sonke siyazi ukuba amayeza kunzima ukuwaginya, adla ngokuhamba nevumba elibi okanye incasa ekrakra. Abantu abaninzi badla ngokungafuni ukulandela imiyalelo yoogqirha babo yokusebenzisa amayeza kuba amayeza akrakra kakhulu ukuba angaginywa, nto leyo echaphazela ukusebenza kakuhle konyango. Enye ingxaki oogqirha kunye nezigulane abaye bajongana nayo ngaphambili kukuba akunakwenzeka ukulinganisa ngokuchanekileyo umthamo kunye noxinzelelo lweyeza kuba akukho mgangatho ufanayo wobungakanani.
Ngo-1833, ingcali yezemithi yaseFransi, uMothes, yavelisa iikhaphu ezithambileyo zegelatin. Usebenzisa indlela apho idosi ethile yeyeza isongelwa kwisisombululo segelatin esishushu esiqina njengoko sipholile ukukhusela iyeza. Ngelixa liginya ikhaphu, isigulane asisenalo ithuba lokungcamla isivuseleli seyeza. Isithako esisebenzayo sesi sidakamizwa sikhutshwa kuphela xa ikhaphu ithathwa ngomlomo emzimbeni kwaye iqokobhe linyibilikisiwe.
Iikhaphu zeGelatin zaduma kwaye kwafunyaniswa ukuba zezona zinto zifanelekileyo zokunyanga, njengoko igelatin yeyona nto iphela ehlabathini enyibilikayo xa umzimba ushushu. Ngo-1874, uJames Murdock eLondon wavelisa ikhaphu yokuqala yegelatin eqinileyo emhlabeni equlathe isiciko kunye nomzimba wekhaphu. Oku kuthetha ukuba umenzi angayifaka ngqo ipowder kwikhaphu.
Ekupheleni kwenkulungwane ye-19, amaMerika ayekhokela uphuhliso lweekhaphu zegelatin. Phakathi kowe-1894 nowe-1897, inkampani yamayeza yaseMelika i-Eli Lilly yakha umzi-mveliso wayo wokuqala wekhaphu zegelatin ukuvelisa uhlobo olutsha lwekhaphu ephindwe kabini, ezivala ngokwayo.
Ngowe-1930, uRobert P. Scherer wasungula umatshini wokuzalisa ozenzekelayo noqhubekayo, owabangela ukuba kube nokwenzeka ukuveliswa kweekhaphu ngobuninzi.
Kangangeminyaka engaphezu kwe-100, i-gelatin ibisoloko iyinto efunekayo kakhulu kwiikhaphu eziqinileyo nezithambileyo kwaye isetyenziswa kakhulu.
