Umhlinzeki weGuar Gum eNingizimu Afrika
Isithambisi semvelo se-galactomannan — esinikeza ukujiya, ukumiswa, kanye nokufakwa kwejeli ekwakhiweni kwemikhiqizo yokuhlanza, ukunakekelwa komuntu siqu, kanye nokusetshenziswa kwezimboni.

Kuyini iGuar Gum?
I-Guar gum iyi-polysaccharide yemvelo etholakala ku-endosperm ye-guar bean, equkethe umgogodla we-mannose one-galactose side chains (galactomannan). Ingenye yama-hydrocolloids emvelo asebenza kahle kakhulu, ikhiqiza i-viscosity ephezulu kakhulu ekugxilweni okuphansi (1–3%) ngenxa yokubopha kwe-hydrogen phakathi kwama-polymer chains ayo anwetshiwe. Ivunyelwe njengesengezo sokudla (E412) futhi isetshenziswa kabanzi emikhiqizweni yokuhlanza, izimonyo, ukuqhekeka kwe-hydraulic, kanye nokukhiqizwa kwephepha.
Ukusebenza Kokuqina Nokumiswa
I-Guar gum iyisithambisi esisebenzayo ezinhlelweni zamanzi ezingathathi hlangothi kuya kweze-alkaline kancane, ikhiqiza i-viscosity ye-pseudoplastic (ukunciphisa ukugunda) egeleza ngaphansi kwamandla okusetshenziswa futhi ibuye ibuyele esimweni sayo lapho iphumula. Le rheology ilungele insipho yesandla ye-gel, ama-gel concentrate okuhlanza, kanye nezihlanzi zoketshezi ezijiyile okumele zithulule noma zipompe kalula kodwa zinamathele ezindaweni eziqondile ngemva kokusetshenziswa. Iphinde imise izinhlayiya ezinganyibiliki (ama-abrasives, ama-pigment) futhi ivimbele ukuhlukaniswa kwesigaba ekwakhiweni okungacacile.
Amabanga kanye Nokunikezwa
Amazinga amaningi e-guar gum ayatholakala, kusukela kumazinga ezimboni afumisa ngokushesha kuya ku-powder omhlophe wekhwalithi yezimonyo. Amafomu athathwe njenge-hydroxypropyl guar anikeza ukucaca okuthuthukisiwe kwesisombululo samanzi. I-Terracore Chemicals inikeza i-guar gum yobuchwepheshe kanye nezinga lokudla ezikhwameni ezingama-25 kg zokuhlanza abakhiqizi bemikhiqizo, abakhiqizi bezimonyo, kanye nabakhiqizi bamakhemikhali bezimayini kulo lonke elaseNingizimu Afrika.
