IiNkcazo zeeMveliso
I-Gum Arabic, ekwaziwa njenge-Acacia Gum, i-chaar gund, i-char goond, okanye i-meska, yitshungama yendalo eyenziwe ngencindi eqinisiweyo ethathwe kwiintlobo ezimbini zomthi womnga; IAcacia senegal kunye neAcacia seyal. Itshungama ivunwa ngokurhweba kwimithi yasendle kuyo yonke iSahel ukusuka eSenegal naseSudan ukuya eSomalia, nangona ibikade ilinywa eArabia nakwintshona yeAsia.
I-Gum Arabic ngumxube onzima we-glycoProteins kunye ne-polysaccharides. Yayingumthombo weswekile i-arabinose kunye ne-ribose, zombini eziye zafunyanwa kwaye zahlukaniswa kuyo, kwaye zibizwa ngokuba yiyo.
IGum arabic isetyenziswa ikakhulu kwishishini lokutya njengesizinzisi. I-Gum arabic isithako esiphambili kwi-lithography yemveli kwaye isetyenziselwa ukuprinta, ukuveliswa kwepeyinti, iglue, izithambiso kunye nezicelo ezahlukeneyo zemizi-mveliso, kubandakanywa nokulawulwa kwe-viscosity kwiinki nakwimizi-mveliso ye-textile, nangona izinto ezingabizi kakhulu zikhuphisana nazo ezininzi zezi ndima.
Nangona igum arabic ngoku iveliswa kakhulu kulo lonke elaseAfrika iSahel, isavunwa kwaye isetyenziswa kuMbindi Mpuma. Umzekelo, abantu abangama-Arabhu basebenzisa itshungama yendalo ukwenza idizethi epholileyo, eswiti, kunye nencasa efana negelato.
