Moetsi oa Theko e Ntle Xanthan Gum Industrial grade CAS:11138-66-2

1) Ka ho eketseha ha sekhahla sa ho kuta, thepa e tloaelehileng ea rheological, ka lebaka la ho timetsoa ha marang-rang a colloidal, fokotsa viscosity le ho hlapolla sekhomaretsi, empa hang ha matla a ho kuta a nyamela, viscosity e ka tsosolosoa, kahoo e na le pompo e ntle. le thepa ea ho sebetsa.Ka ho sebelisa thepa ena, xanthan gum e kenngoa ho mokelikeli o lokelang ho teteaneng.Mokelikeli ha o bonolo feela ho phalla ts'ebetsong ea lipalangoang, empa hape o ka hlaphoheloa ho viscosity e hlokahalang ka mor'a hore e ntse e le teng.Ka hona, e sebelisoa haholo indastering ea lino tse tahang.

2）Mokelikeli o phahameng oa viscosity o nang le 2% ~ 3% xanthan gum boemong bo tlaase, ka viscosity ho fihlela ho 3 ~ 7Pa.s.Viscosity ea eona e phahameng e etsa hore e be le litebello tse pharaletseng tsa kopo, empa ka nako e ts'oanang, e tlisa khathatso ho ts'ebetsong ea tlhahiso ea morao-rao.0.1% NaCl le matsoai a mang a sa tsitsang le Ca, Mg le matsoai a mang a bivalent a ka fokotsa hanyenyane ponahalo ea tharollo e tlaase ea sekhomaretsi ka tlase ho 0.3%, empa a ka eketsa viscosity ea tharollo ea sekhomaretsi ka mahloriso a phahameng.

3) The viscosity ea xanthan gum e thibelang mocheso ha e na phetoho e batlang e le bophara ba mocheso (- 98 ~ 90 ℃).Viscosity ea tharollo ha ea ka ea fetoha haholo le haeba e ne e bolokiloe ho 130 ℃ bakeng sa 30 min ebe e pholile.Ka mor'a lipotoloho tse 'maloa tsa ho qhibiliha ha leqhoa, viscosity ea sekhomaretsi ha ea ka ea fetoha.Ka pel'a letsoai, tharollo e na le botsitso bo botle ba mocheso.Haeba tekanyo e nyenyane ea electrolyte, e kang 0.5% NaCl, e kenngoa mocheso o phahameng, viscosity ea tharollo ea glue e ka tsitsisoa.

4) The viscosity ea acid e hanyetsanang le alkaline xanthan gum aqueous solution e batla e ikemetse ho pH.Thepa ena e ikhethang ha e na li-thickeners tse ling tse kang carboxymethyl cellulose (CMC).Haeba motsoako oa inorganic acid ka har'a tharollo ea sekhomaretsi o phahame haholo, tharollo ea sekhomaretsi e tla ba e sa tsitsang;Tlas'a mocheso o phahameng, hydrolysis ea polysaccharide ka acid e tla etsahala, e leng ho tla etsa hore viscosity ea glue e fokotsehe.Haeba litaba tsa NaOH li feta 12%, xanthan gum e tla belisoa kapa e be le pula.Haeba motsoako oa sodium carbonate o feta 5%, xanthan gum le eona e tla kenngoa.

6） Xanthan gum e lumellanang e ka tsoakoa le litharollo tse sebelisoang hangata ka bongata ba lijo, haholo-holo ka alginate, starch, carrageenan le carrageenan.The viscosity ea tharollo eketseha ka mokgwa wa superposition.E bontša ho lumellana hantle ka tharollo ea metsi a nang le matsoai a sa tšoaneng.Leha ho le joalo, li-ion tsa tšepe tse phahameng tsa valence le pH e phahameng li tla etsa hore li se ke tsa tsitsa.Ho eketsa motsoako o rarahaneng ho ka thibela ketsahalo ea ho se lumellane.

7).Ka mefuta e mengata haholo ea mocheso, pH le letsoai la letsoai, ho bonolo ho qhibiliha ka metsing, 'me tharollo ea eona ea metsi e ka lokisoa mocheso oa kamore.Ha u hlohlelletsa, ho kopanya moea ho lokela ho fokotsoa.Haeba xanthan gum e kopantsoe le lintho tse omeletseng esale pele, tse kang letsoai, tsoekere, MSG, joalo-joalo, ebe e kolobisoa ka metsi a seng makae, 'me qetellong e kopane le metsi, tharollo e lokiselitsoeng ea sekhomaretsi e na le ts'ebetso e ntle.E ka qhibiliha ka litharollo tse ngata tsa organic acid, 'me ts'ebetso ea eona e tsitsitse.

8）Bokhoni ba ho jara ba 1% e qhalakantsoeng xanthan gum solution ke 5N/m2, e leng sesebelisoa se setle sa ho emisa le emulsion stabilizer ho li-additives tsa lijo.

9) Metsi a bolokang xanthan gum a na le litlamorao tse ntle tsa ho boloka metsi le ho boloka lijo tse ncha.
