Xanthan gum, izwi kandi nka Hanseum gum, ni ubwoko bwa exopolysaccharide ya mikorobe ikorwa na Xanthomnas campestris binyuze mu buhanga bwo guhinga hakoreshejwe karubohidrati nk'ibikoresho by'ingenzi (nk'ifu y'ibigori). Ifite rheology yihariye, ishonga neza mu mazi, ubushyuhe n'ubudahangarwa bw'aside, kandi ihura neza n'ubwoko butandukanye bw'imyunyu, nk'ikintu gikomeza ubushyuhe, ikintu gihagarika, emulsifier, stabilizer, ishobora gukoreshwa cyane mu biribwa, peteroli, ubuvuzi n'izindi nganda zirenga 20, ubu ni yo polysaccharide nini ku isi ikorwa kandi ikoreshwa cyane cyane muri mikorobe.
Imitungo:Xanthan gum ni ifu yimukanwa y'umuhondo woroshye kugeza ku wera, ihumura gato. Irashonga mu mazi akonje n'ashyushye, ifite umuti utagira aho ubogamiye, irwanya ubukonje cyangwa gushonga, ntishongeshwa na ethanol. Ikwirakwira mu mazi ikayivanga mu bwoko bwa colloid ihindagurika cyane kandi ikora neza.
Porogaramu:Kubera rheology yayo idasanzwe, ubushobozi bwo gushonga neza mu mazi, no kudahungabana mu buryo budasanzwe mu gihe cy'ubushyuhe n'ishingiro rya aside, xanthan gum yabaye ingenzi mu bintu byinshi bitandukanye. Nk'ikintu gikomeza ubushyuhe, ikintu gihagarika ubushyuhe, ikintu gitera imbaraga, n'ikintu gitera imbaraga, yageze mu nganda zirenga 20, harimo ibiribwa, peteroli, ubuvuzi, n'izindi nyinshi.
Inganda z'ibiribwa zagize uruhare runini mu kunguka ubushobozi budasanzwe bwa xanthan gum. Ubushobozi bwayo bwo kongera imiterere n'uburyo ibiryo bihinduka byatumye ikundwa n'abakora ibiryo. Byaba mu isosi, isosi, cyangwa mu bicuruzwa byo guteka, xanthan gum ituma irushaho kuryoha mu kanwa. Ihuye n'imyunyu itandukanye birushaho kugira uruhare mu gutuma ikoreshwa mu buryo butandukanye mu gutegura ibiryo.
Mu nganda zikora peteroli, xanthan gum igira uruhare runini mu gucukura no gusya amazi. Imiterere yayo yihariye ya rheological ituma iba inyongeramusaruro nziza, yongera ubukana bw'amazi no kugumana ubusugire. Byongeye kandi, ikora nk'igikoresho cyo kugenzura kuyungurura, ikagabanya ikorwa rya filter cakes mu gihe cyo gucukura. Ubushobozi bwayo bwo gukora mu gihe cy'ubushyuhe bukabije n'umuvuduko w'amazi byatumye iba amahitamo meza mu bahanga mu bijyanye n'ibikomoka kuri peteroli.
Urwego rw'ubuvuzi kandi rwungukira cyane ku miterere idasanzwe ya xanthan gum. Imyitwarire yayo ya rheological ituma imiti isohoka neza, bigatuma iba ikintu cyiza mu miti. Byongeye kandi, kuba ihuza n'ibinyabuzima no kwangirika kwayo bituma ikoreshwa mu buryo butandukanye mu buvuzi nko gupfuka ibisebe no gutanga imiti igenzurwa.
Uretse inganda zavuzwe haruguru, xanthan gum iboneka mu zindi nzego nyinshi, harimo n’inganda zikora imiti ya buri munsi. Kuva ku bwonko bw’amenyo kugeza kuri shampoo, xanthan gum igira uruhare mu gutuma ibi bicuruzwa byifuzwa kandi bigakomera.
Kuba xanthan gum ikora mu bucuruzi ntagereranywa ugereranije n'izindi polysaccharide za mikorobe. Uburyo ikoreshwamo butandukanye n'imiterere yayo idasanzwe byatumye iba ikintu gikundwa n'inganda nyinshi. Nta yindi polysaccharide ya mikorobe ishobora kuyikoresha mu buryo butandukanye no mu buryo ikora.

Ububiko:Xanthan gum ishobora gukoreshwa cyane mu gucukura amavuta, imiti, ibiribwa, ubuvuzi, ubuhinzi, amarangi, ibumba, impapuro, imyenda, amavuta yo kwisiga, ubwubatsi n'inganda ziturika ndetse n'izindi nganda zirenga 20 mu bwoko bw'ibicuruzwa bigera ku 100. Kugira ngo yorohereze kubibika no gutwara, muri rusange ikorwamo ibintu byumye. Kumisha kwayo bifite uburyo butandukanye bwo kuyitunganya: kumisha ikoresheje umwuka, kumisha ingoma, kumisha imashini, kumisha imashini mu buriri no kumisha umwuka. Kubera ko ari ikintu kidakoresha ubushyuhe bwinshi, ntigishobora kwihanganira ubushyuhe bwinshi igihe kirekire, bityo gukoresha kumisha imashini bizatuma idashonga cyane. Nubwo ubushobozi bwo kumisha ingoma mu bushyuhe buri hejuru, imiterere yayo iragoye, kandi biragoye kugeraho mu nganda nini. Kumisha imashini mu buriri hakoreshejwe imiterere idafite ubushyuhe, bitewe n'ubushyuhe bwinshi n'uburyo bwo kohereza ibintu byinshi, ndetse no gusya no gusya, igihe cyo kubika ibikoresho nacyo ni gito, bityo ikaba ikwiriye kumisha ibikoresho bito bito bito bikoresha ubushyuhe nka xanthan gum.
Amabwiriza yo kwirinda gukoresha:
1. Mu gutegura umuti wa xanthan gum, niba gukwirakwira bidahagije, hazagaragara uduce duto. Uretse gukurura neza, ushobora kuvangwa mbere n'ibindi bikoresho fatizo, hanyuma ukongeramo amazi mu gihe urimo gukurura. Niba bigoye gukurura, ushobora kongeramo umuti uvanze n'amazi, urugero nka ethanol nke.
2. Xanthan gum ni polysaccharide ya anionic, ishobora gukoreshwa hamwe n'ibindi bintu bya anionic cyangwa bitari ionic, ariko ntishobora kuba ihuye n'ibintu bya cationic. Umuti wayo uhura neza kandi ugakomera ku myunyu myinshi. Kongeramo electrolytes nka sodium chloride na potasiyumu chloride bishobora kongera ubukana no gukomera kwayo. Kalisiyumu, manyeziyumu n'indi myunyu ya bivalent byagaragaje ingaruka nk'izo ku bukana bwabyo. Iyo ubukana bw'umunyu buri hejuru ya 0.1%, ubukana bwiza bugerwaho. Ubukana bwinshi bw'umunyu ntibutuma umuti wa xanthan gum ukomera, kandi ntibigira ingaruka ku bukana bwa rheology yayo, gusa pH> Ku isaha ya saa yine (ibiryo bikunze kugaragara), imyunyu ya bivalent metal igaragaza ubushake bwo gukora gels. Mu gihe cy'aside cyangwa idafite aho ibogamiye, imyunyu yayo ya trivalent metal nka aluminiyumu cyangwa icyuma ikora gels. Ubunini bw'imyunyu ya monovalent metal bubuza gelation.
3. Xanthan gum ishobora guhuzwa n'ibintu byinshi bifasha mu bucuruzi, nka cellulose derivatives, starch, pectin, dextrin, alginate, carrageenan, nibindi. Iyo ihujwe na galactomannan, igira ingaruka nziza ku kongera ubukana bw'ibimera.
Mu gusoza, gum ya xanthan ni igitangaza nyacyo cya siyansi ya none. Ubushobozi bwayo bwihariye bwo gukomatanya, gusunikira, gusunikira, no gusunikira byahinduye uburyo inganda zitandukanye zikora. Kuva ku biribwa dukoresha kugeza ku miti twishingikirizaho, ingaruka za gum ya xanthan ntizishidikanywaho. Gukundwa kwayo mu bucuruzi no gukoreshwa mu buryo bwagutse bituma iba isoko ikomeye mu isi y'ibikoresho. Ishimire ubuhanga bwa gum ya xanthan kandi ufungure ubushobozi bwayo mu bicuruzwa byawe uyu munsi.
