Xanthan gum hajoale ke gel ea bio e phahameng ka ho fetesisa mabapi le ho tenya, ho fanyeha, ho etsa emulsification le botsitso machabeng. Palo ea lihlopha tsa pyruvate qetellong ea ketane ea lehlakoreng la molek'hule ea xanthan gum e na le t?usumetso e kholo ho thepa ea eona. Xanthan gum e na le thepa e akaretsang ea li-polymers tsa ketane e telele, empa e na le lihlopha tse sebetsang ho feta li-polymers tse tloaelehileng 'me e bont?a thepa e ikhethang tlas'a maemo a itseng. Ho lumellana ha eona ka tharollo ea metsi ho fapane, ho bont?a lit?obotsi tse fapaneng tlas'a maemo a fapaneng.

1. Ho emisoa le thepa ea emulsifying

Xanthan gum e na le phello e ntle ea ho emisa lintho tse tiileng le marotholi a oli. Limolek'hule tsa Xanthan gum sol li ka etsa li-helical copolymers tse kopantsoeng haholo, tsa etsa gel e senyehang joalo ka sebopeho sa marang-rang se ka t?ehetsang morphology ea likaroloana tse tiileng, marotholi le li-bubble, tse bonts'ang botsitso bo matla ba emulsifying le bokhoni bo phahameng ba ho emisa.

2. Ho qhibiliha ha metsi hantle

Xanthan gum e ka qhibiliha kapele ka metsing 'me e na le ho qhibiliha ha metsi hantle. Haholo-holo e qhibilihang ka metsing a batang, e ka felisa ts'ebetso e rarahaneng 'me e bonolo ho e sebelisa. Leha ho le joalo, ka lebaka la hydrophilicity ea eona e matla, haeba metsi a eketsoa ka ho toba ntle le ho sisinyeha ho lekaneng, lera le ka ntle le tla monya metsi 'me le atolose ho ba gel, e leng ho tla thibela metsi ho kena ka hare le ho ama katleho ea eona. Ka hona, e tlameha ho sebelisoa ka nepo. Kopanya xanthan gum phofo e omileng kapa li-additives tsa phofo tse omeletseng tse kang letsoai le tsoekere, 'me butle-butle u li kenye metsing a pholileng ho etsa tharollo bakeng sa t?ebeliso.

3. Thepa e teteaneng

Tharollo ea Xanthan gum e na le lit?obotsi tsa "conconcentration" e tlaase le viscosity e phahameng (viscosity ea 1% ea tharollo ea metsi e lekana le makhetlo a 100 a gelatin), e leng se etsang hore e be motenya o sebetsang hantle.

4. Pseudoplasticity

Tharollo ea xanthan gum e na le viscosity e phahameng tlas'a maemo a tsitsitseng kapa a tlaase, 'me e bont?a ho fokotseha ho hoholo ha viscosity tlas'a maemo a phahameng a ho kuta, empa sebopeho sa molek'hule se lula se sa fetohe. Ha matla a ho kuta a felisitsoe, viscosity ea pele e tsosolosoa hang-hang. Kamano pakeng tsa matla a ho kuta le viscosity ke polasetiki e feletseng. Pseudoplasticity ea xanthan gum e hlahella haholo, 'me pseudoplasticity ena e sebetsa haholo bakeng sa ho tsitsisa ho fanyeha le li-emulsions.

5. Botsitso ba mocheso

The viscosity ea xanthan gum solution ha e fetohe haholo ka mocheso. Ka kakaretso, li-polysaccharides li na le liphetoho tsa viscosity ka lebaka la ho futhumatsa, empa viscosity ea xanthan gum aqueous solution e lula e batla e sa fetohe pakeng tsa 10-80 ℃. Esita le litharollo tse nang le metsi a mangata a tlaase li ntse li bont?a viscosity e phahameng e tsitsitseng holim'a mefuta e mengata ea mocheso. Ho futhumatsa 1% xanthan gum solution (e nang le 1% potassium chloride) ho tloha ho 25 ℃ ho ea ho 120 ℃ ho fokotsa viscosity ea eona ka 3%.

6. Ho tsitsisa ho acidity le alkalinity

Tharollo ea Xanthan gum e tsitsitse haholo ho acidity le alkalinity, 'me viscosity ea eona ha e amehe pakeng tsa pH 5-10. Ho na le phetoho e nyane ea viscosity ha pH e le ka tlase ho 4 le e kholo ho feta 11. Ka har'a pH ea 3-11, litekanyetso tse phahameng le tse fokolang tsa viscosity li fapana ka tlase ho 10%. Xanthan gum e ka qhibiliha ka litharollo tse fapaneng tsa asiti, joalo ka 5% sulfuric acid, 5% nitric acid, 5% acetic acid, 10% hydrochloric acid, le 25% ea phosphoric acid. Litharollo tsena tsa xanthan gum acid li tsitsitse mocheso oa kamore 'me li ke ke tsa fetoha boleng ba likhoeli tse' maloa. Xanthan gum e ka boela ea qhibiliha ka tharollo ea sodium hydroxide 'me e na le thepa e teteaneng. Tharollo e hlahisoang e tsitsitse haholo mocheso oa kamore. Xanthan gum e ka senyeha ke li-oxidants tse matla tse kang perchloric acid le persulfate, 'me ho senyeha ho potlakisa ka mocheso o ntseng o eketseha.
