Xanthan chingamu parizvino ndiyo yakanakisa bio gel maererano nekukora, kumiswa, emulsification, uye kugadzikana pasi rese. Huwandu hwemapoka epyruvate pakupera kwema molecular side chain ye xanthan gum ine simba rakakura pane yayo. Xanthan chingamu ine hunhu hwehurefu-cheni mapolymers, asi ine akawanda anoshanda mapoka kupfuura akajairwa mapolymers uye inoratidza yakasarudzika zvivakwa pasi pemamiriro chaiwo. Kuenderana kwayo mune aqueous solution kwakasiyana, kuratidza maitiro akasiyana pasi pemamiriro akasiyana.

1. Kumiswa uye emulsifying zvivakwa

Xanthan chingamu ine yakanaka kumiswa mhedzisiro pane isinganyungudika solids uye madonhwe emafuta. Xanthan gum sol mamorekuru anogona kuumba super bonded helical copolymers, ichigadzira gel isina kusimba senge network dhizaini inogona kutsigira morphology yezvakasimba zvimedu, madonhwe, uye mabhuru, ichiratidza yakasimba emulsifying kugadzikana uye yakakwirira kumiswa kugona.

2. Kunyungudika kwemvura kwakanaka

Xanthan chingamu inogona kunyungudika nekukurumidza mumvura uye ine yakanaka solubility yemvura. Kunyanya kunyungudika mumvura inotonhora, inogona kubvisa kugadzirisa kwakaoma uye iri nyore kushandisa. Zvisinei, nekuda kweiyo hydrophilicity yakasimba, kana mvura yakawedzerwa zvakananga pasina kukwana kwakakwana, jira rekunze rinotora mvura uye rinowedzera kuva gel, izvo zvinodzivirira mvura kupinda mukati memukati uye inokanganisa kushanda kwayo. Naizvozvo, inofanira kushandiswa nemazvo. Sanganisa xanthan gum poda yakaoma kana zvidimbu zvehupfu hwakaoma zvakadai semunyu uye shuga, uye zvishoma nezvishoma uwedzere kumvura inomutsa kuti uite mhinduro yekushandisa.

3. Kukora pfuma

Xanthan chingamu mhinduro ine hunhu hwekudzika dzika uye yakakwirira viscosity (iyo viscosity ye 1% aqueous solution yakaenzana ne100 times iyo yegelatin), ichiita iko kukora.

4. Pseudoplasticity

Iyo xanthan gum solution ine yakakwira viscosity pasi pe static kana yakaderera shear mamiriro, uye inoratidza kuderera kwakanyanya muviscosity pasi peyakanyanya shear mamiriro, asi iyo molecular chimiro inoramba isingachinji. Kana simba rekugera rabviswa, viscosity yepakutanga inodzorerwa pakarepo. Ukama pakati peshear force uye viscosity ipurasitiki yakazara. Iyo pseudoplasticity ye xanthan chingamu yakakurumbira, uye iyi pseudoplasticity inoshanda zvakanyanya mukudzikamisa kumiswa uye emulsions.

5. Kugadzikana kupisa

Iyo viscosity ye xanthan gum mhinduro haichinji zvakanyanya nekushisa. Kazhinji, mapolysaccharides anochinja viscosity nekuda kwekudziya, asi viscosity yexanthan gum aqueous solution inoramba isina kushanduka pakati pe10-80 ℃. Kunyangwe yakaderera yekuisa aqueous mhinduro ichiri kuratidza yakagadzikana yakakwirira viscosity pane yakakura tembiricha renji. Kupisa 1% xanthan gum solution (ine 1% potassium chloride) kubva pa25 ℃ kusvika 120 ℃ inongoderedza viscosity yayo ne3%.

6. Kugadzikana kune acidity uye alkalinity

Xanthan chingamu mhinduro yakanyatsogadzikana kune acidity uye alkalinity, uye viscosity yayo haina kukanganiswa pakati pH 5-10. Pane kuchinja kuduku muviscosity apo pH iri pasi pe 4 uye yakakura kudarika 11. Mukati ye pH ye 3-11, huwandu hwepamusoro uye hushoma hwekuona hutsika hunosiyana nechepasi pe10%. Xanthan chingamu inogona kunyungudika mune dzakasiyana siyana asidhi mhinduro, senge 5% sulfuric acid, 5% nitric acid, 5% acetic acid, 10% hydrochloric acid, uye 25% phosphoric acid. Aya xanthan gum acid mhinduro dzakagadzikana pamhepo tembiricha uye haishanduke mumhando kwemwedzi yakati wandei. Xanthan chingamu inogona zvakare kunyungudika mu sodium hydroxide solution uye ine thickening zvimiro. Mushonga unoguma wakanyatsogadzikana pakupisa kwekamuri. Xanthan chingamu inogona kuderedzwa neakasimba oxidants senge perchloric acid uye persulfate, uye kuderera kunowedzera nekuwedzera tembiricha.
