I-Xanthan gum, eyaziwa nangokuthi i-Hanseum gum, uhlobo lwe-microbial exopolysaccharide ekhiqizwa yi-Xanthomnas campestris ngobunjiniyela bokuvubela kusetshenziswa ama-carbohydrate njengezinto eziyinhloko zokusetshenziswa (njengesitashi sommbila). Ine-rheology ehlukile, ukuncibilika kwamanzi okuhle, ukushisa kanye nokuqina kwesisekelo se-acid, futhi ihambisana kahle nezinhlobonhlobo zosawoti, njenge-ejenti yokuqina, i-suspension agent, i-emulsifier, i-stabilizer, ingasetshenziswa kabanzi ekudleni, kuphethiloli, kwezokwelapha nakwezinye izimboni ezingaphezu kuka-20, okwamanje iyisilinganiso sokukhiqiza esikhulu kunazo zonke emhlabeni futhi i-microbial polysaccharide esetshenziswa kabanzi kakhulu.
Izakhiwo:I-Xanthan gum iyimpuphu enyakazayo ephuzi kancane kuya komhlophe, inephunga elincane. Incibilika emanzini abandayo nashisayo, iyisisombululo esingathathi hlangothi, imelana nokubanda nokuncibilika, ayincibiliki ku-ethanol. Ihlakazeka ngamanzi bese ixuba ibe yi-colloid eqinile enamathelayo ehlala emanzini.
Isicelo：Ngenxa ye-rheology yayo eyingqayizivele, ukuncibilika kwamanzi okuhle, kanye nokuqina okumangalisayo ngaphansi kwezimo zokushisa kanye ne-acid-base, i-xanthan gum isibe yingxenye ebalulekile ezinhlotsheni eziningi zokusetshenziswa. Njenge-ejenti yokujiya, i-ejenti yokumiswa, i-emulsifier, kanye ne-stabilizer, isithole indlela yayo ezimbonini ezingaphezu kuka-20, okuhlanganisa ukudla, uphethiloli, imithi, kanye nezinye eziningi.
Imboni yokudla ibe ngomunye wabazuzi abayinhloko bamakhono angavamile e-xanthan gum. Amandla ayo okuthuthukisa ukuthungwa kanye nokuvumelana kwemikhiqizo yokudla kwenze kwaba ukukhetha okuthandwayo phakathi kwabakhiqizi. Kungakhathaliseki ukuthi kusemasosweni, ekubhakeni, noma ezintweni zokubhaka, i-xanthan gum iqinisekisa umuzwa womlomo obushelelezi futhi okhangayo. Ukuhambisana kwayo nosawoti abahlukahlukene kunezela kakhulu ekusebenzeni kwayo okuhlukahlukene ekulungiseleleni ukudla.
Embonini kaphethiloli, i-xanthan gum idlala indima ebalulekile ekubholeni nasekuqhekekeni koketshezi. Izakhiwo zayo ezihlukile ze-rheological ziyenza ibe yisithasiselo esifanele, ithuthukisa ukujiya koketshezi kanye nokuqina. Ngaphezu kwalokho, isebenza njenge-ejenti yokulawula ukuhlunga, inciphisa ukwakheka kwamakhekhe okuhlunga ngesikhathi senqubo yokubhoboza. Amandla ayo okusebenza ngaphansi kwezimo zokushisa okukhulu kanye nengcindezi yenze kwaba ukukhetha okuthandwayo phakathi kochwepheshe bezindawo zikaphethiloli.
Insimu yezokwelapha nayo izuza kakhulu ezimpahleni ezingavamile ze-xanthan gum. Ukuziphatha kwayo kwe-rheological kuvumela ukukhishwa kwemithi okulawulwayo, okwenza kube yisithako esifanelekile ekwakhiweni kwemithi. Ngaphezu kwalokho, ukuhambisana kwayo nezinto eziphilayo kanye nokubola kwayo kwenza ifanelekele ukusetshenziswa kwezokwelapha okuhlukahlukene njengokubopha amanxeba kanye nezinhlelo zokulethwa kwemithi ezilawulwayo.
Ngaphandle kwezimboni ezishiwo ngenhla, i-xanthan gum ingena kwezinye izimboni eziningi, okuhlanganisa nemboni yamakhemikhali yansuku zonke. Kusukela ku-toothpaste kuya kuma-shampoo, i-xanthan gum inegalelo ekubunjweni nasekuzinzeni kwale mikhiqizo.
Ukukwazi kwayo ukuhweba nge-xanthan gum akunakuqhathaniswa uma kuqhathaniswa namanye ama-polysaccharide amancane. Ububanzi bayo bokusetshenziswa kanye nezakhiwo zayo ezivelele kwenze kwaba yisithako esithandwa kakhulu ngabakhiqizi abaningi. Ayikho enye i-polysaccharide encane engalingana nokusebenza kwayo okuhlukahlukene.

Isitoreji:I-Xanthan gum ingasetshenziswa kabanzi ekukhishweni kwamafutha, amakhemikhali, ukudla, imithi, ezolimo, odayi, izinto zobumba, iphepha, izindwangu, izimonyo, ukwakhiwa kanye nokukhiqiza okuqhumayo kanye neminye imboni engaphezu kuka-20 ezinhlotsheni ezingaba yi-100 zemikhiqizo. Ukuze kube lula ukugcina kanye nokuthuthwa, ngokuvamile yenziwa imikhiqizo eyomile. Ukomisa kwayo kunezindlela ezahlukene zokwelapha: ukomisa nge-vacuum, ukomisa nge-drum, ukomisa nge-spray, ukomisa nge-fluidized bed dryer kanye nokomisa ngomoya. Ngenxa yokuthi iyinto ezwela ukushisa, ayikwazi ukumelana nokwelashwa kokushisa okuphezulu isikhathi eside, ngakho-ke ukusetshenziswa kokomisa nge-spray kuzokwenza ingancibiliki kakhulu. Nakuba ukusebenza kahle kokushisa kokomisa nge-drum kuphezulu, isakhiwo semishini siyinkimbinkimbi kakhulu, futhi kunzima ukukufeza ekukhiqizweni okukhulu kwezimboni. Ukomisa nge-fluidized bed spheres nge-inert spheres, ngenxa yokushisa okuthuthukisiwe kanye nokudluliselwa kwesisindo kanye nemisebenzi yokugaya nokuchoboza, isikhathi sokugcina izinto naso sifushane, ngakho-ke kufanelekile ukomisa izinto eziqinile ezizwela ukushisa njenge-xanthan gum.
Izinyathelo Zokuqapha Zokusetshenziswa:
1. Lapho ulungisa isixazululo se-xanthan gum, uma ukuhlakazeka kunganele, kuzovela amahlule. Ngaphezu kokuxubha ngokuphelele, ingaxutshwa nezinye izinto zokusetshenziswa, bese ifakwa emanzini ngenkathi ixuba. Uma kusenzima ukuyihlakaza, kungafakwa i-solvent exubile enamanzi, njengenani elincane le-ethanol.
2. I-Xanthan gum iyi-polysaccharide ye-anionic, engasetshenziswa kanye nezinye izinto ze-anionic noma ezingezona i-ionic, kodwa ayikwazi ukuhambisana nezinto ze-cationic. Isixazululo sayo sinokuhambisana okuhle kakhulu nokuzinza kusawoti omningi. Ukwengeza ama-electrolyte njenge-sodium chloride ne-potassium chloride kungathuthukisa ukuzinza kwayo. I-calcium, i-magnesium kanye nezinye usawoti we-bivalent kubonise imiphumela efanayo ekuzinzeni kwawo. Lapho ukugcwala kukasawoti kuphakeme kuno-0.1%, i-viscosity efanele ifinyelelwa. Ukugcwala kukasawoti okuphezulu kakhulu akuthuthukisi ukuzinza kwesisombululo se-xanthan gum, futhi akuthinti i-rheology yaso, kuphela i-pH> Ngehora le-10 (imikhiqizo yokudla ayiveli njalo), usawoti wensimbi we-bivalent ubonisa ukuthambekela kokwakha ama-gel. Ngaphansi kwezimo ze-acidic noma ezingathathi hlangothi, usawoti wayo wensimbi we-trivalent njenge-aluminium noma i-iron wenza ama-gel. Okuqukethwe okuphezulu kosawoti wensimbi we-monovalent kuvimbela i-gelation.
3. I-Xanthan gum ingahlanganiswa neziningi zezinto eziqinisa ukwakheka kwezentengiselwano, njengezinto ezitholakala ku-cellulose, isitashi, i-pectin, i-dextrin, i-alginate, i-carrageenan, njll. Uma ihlanganiswa ne-galactomannan, inomphumela wokubambisana ekwandiseni i-viscosity.
Ekuphetheni, i-xanthan gum iyisimangaliso sangempela sesayensi yesimanje. Amakhono ayo ahlukile njenge-ejenti yokujiya, i-suspension agent, i-emulsifier, kanye ne-stabilizer ashintshe indlela izimboni ezahlukene ezisebenza ngayo. Kusukela ekudleni esikudlayo kuya emithini esithembele kuyo, umthelela we-xanthan gum awunakuphikwa. Ukuthandwa kwayo kwezentengiselwano kanye nokusetshenziswa kwayo okubanzi kuyenza ibe yindawo enamandla yangempela emhlabeni wezithako. Yamukela umlingo we-xanthan gum bese uvula amandla ayo emikhiqizweni yakho namuhla.
