Umenzi wexabiso eliLungileyo Xanthan Gum Ibakala loShishino CAS:11138-66-2 Umfanekiso ofakiweyo

inkcazelo emfutshane:

I-Xanthan gum, ekwabizwa ngokuba yi-Hanseonggum, luhlobo lwe-microbial exopolysaccharide eveliswa yi-Xanthomnas campestris enecarbohydrate njengeyona nto iphambili ekrwada (efana nesitatshi sombona) ngobunjineli bokubila.Ine-rheology ekhethekileyo, ukunyibilika kakuhle kwamanzi, ukuzinza kubushushu kunye nesiseko se-asidi, kwaye ihambelana kakuhle neentlobo zeetyuwa.Njenge-arhente etyebisayo, i-agent yokunqunyanyiswa, i-emulsifier, i-stabilizer, inokusetyenziswa ngokubanzi kukutya, i-petroleum, amayeza kunye nakwamanye amashishini angaphezu kwama-20, okwangoku isesona sikali semveliso yehlabathi kunye ne-microbial polysaccharide esetyenziswa ngokubanzi.

I-Xanthan gum iluhlaza tyheli ukuya kumgubo omhlophe oshukumayo, enevumba elincinane.Inyibilika kumanzi abandayo nashushu, isisombululo esingathathi hlangothi, simelana neqhwa kunye nokunyibilika, asinyibiliki kwi-ethanol.Ukusasazwa kwamanzi, i-emulsification ibe yi-hydrophilic viscous colloid ezinzileyo.

Iimpawu

1) Ngokunyuka kwezinga lokucheba, iimpawu ze-rheological eziqhelekileyo, ngenxa yokutshatyalaliswa kwenethiwekhi ye-colloidal, ukunciphisa i-viscosity kunye nokunciphisa iglue, kodwa emva kokuba i-shear force iphelile, i-viscosity inokubuyiselwa, ngoko inokumpompa okulungileyo. kunye neempawu zokusetyenzwa.Ngokusebenzisa le propati, i-xanthan gum yongezwa kulwelo olufuna ukuqiniswa.Ulwelo alukho lula kuphela ukuhamba kwinkqubo yothutho, kodwa lunokubuyisela kwakhona kwi-viscosity efunekayo emva kokuba isekho.Ke ngoko, isetyenziswa kakhulu kushishino lwesiselo.

2）Ulwelo oluphezulu lwe-viscosity equkethe i-2% ~ 3% i-xanthan gum ekugxininiseni okuphantsi, kunye ne-viscosity ukuya kwi-3 ~ 7Pa.s.I-viscosity yayo ephezulu yenza ukuba ibe nethemba elibanzi lesicelo, kodwa kwangaxeshanye, izisa inkathazo kwi-post-processing yemveliso.I-0.1% ye-NaCl kunye nezinye i-salts ezingabonakaliyo kunye ne-Ca, i-Mg kunye nezinye iityuwa ze-bivalent zinokunciphisa kancane i-viscosity yesisombululo seglue ephantsi kwe-0.3%, kodwa inokunyusa i-viscosity yesisombululo seglue kunye nokugxila okuphezulu.

3）I-viscosity ye-xanthan gum ekwazi ukumelana nobushushu phantse ayinalo utshintsho kuluhlu olubanzi lobushushu (- 98~90 ℃).I-viscosity yesisombululo ayizange itshintshe kakhulu nangona igcinwe kwi-130 ℃ ye-30 min kwaye ipholile.Emva kwemijikelo emininzi yokuqhaqhazela, i-viscosity yeglue ayizange itshintshe.Xa kukho ityuwa, isisombululo sinokuzinza kakuhle kwe-thermal.Ukuba inani elincinci le-electrolyte, njenge-0.5% ye-NaCl, yongezwa kwiqondo lokushisa eliphezulu, i-viscosity yesisombululo seglue inokuzinza.

4）I-viscosity ye-asidi exhathisayo kunye ne-alkaline xanthan gum isisombululo se-aqueous siphantse sizimele kwi-pH.Le propati ikhethekileyo ayinazo ezinye izinto ezityebisayo ezifana ne-carboxymethyl cellulose (CMC).Ukuba ukuxinwa kwe-asidi ye-inorganic kwisisombululo seglue kuphezulu kakhulu, isisombululo seglue siya kuba singazinzile;Ngaphantsi kweqondo lokushisa eliphezulu, i-hydrolysis ye-polysaccharide nge-asidi iya kwenzeka, eya kubangela ukuba i-viscosity yeglue iyancipha.Ukuba umxholo we-NaOH ungaphezulu kwe-12%, i-xanthan gum iya kufakwa i-gelled okanye i-precipitated.Ukuba i-concentration ye-sodium carbonate ingaphezulu kwe-5%, i-xanthan gum nayo iya kufakwa.

5）I-anti enzymatic xanthan gum skeleton inesakhono esisodwa sokungafakwa kwi-hydrolyzed yi-enzymes ngenxa yempembelelo yokukhusela yamatyathanga asecaleni.

6) I-xanthan gum ehambelanayo inokuxutywa kunye nezona zisombululo ze-thickener zokutya ezisetyenziswa ngokuqhelekileyo, ngakumbi nge-alginate, isitashi, i-carrageenan kunye ne-carrageenan.I-viscosity yesisombululo iyanda ngendlela ye-superposition.Ibonisa ukuhambelana kakuhle kwizisombululo ezinamanzi kunye neetyuwa ezahlukeneyo.Nangona kunjalo, i-ion zensimbi ephezulu ye-valence kunye ne-pH ephezulu iya kubenza bangazinzi.Ukongeza i-agent eyinkimbinkimbi inokuthintela ukuvela kokungahambelani.

7) I-xanthan gum enyibilikayo inyibilika ngokulula emanzini kwaye ayinyibiliki kwizinyibilikisi zepolar ezinje ngotywala kunye neketone.Kuluhlu olubanzi kakhulu lweqondo lokushisa, i-pH kunye noxinzelelo lwetyuwa, kulula ukunyibilika emanzini, kwaye isisombululo sayo samanzi sinokulungiswa kwiqondo lokushisa.Xa uvuselela, ukuxuba umoya kufuneka kuncitshiswe.Ukuba i-xanthan gum ixutywe kunye nezinye izinto ezomileyo kwangaphambili, njengetyuwa, iswekile, i-MSG, njl., emva koko ixutywe ngamanzi amancinci, kwaye ekugqibeleni ixutywe namanzi, isisombululo esilungisiweyo seglue sinomsebenzi ongcono.Inokuchithwa kwiisombululo ezininzi ze-asidi ye-organic, kwaye ukusebenza kwayo kuzinzile.

I-8) Umthamo wokuthwala we-1% isisombululo se-xanthan gum esichithwayo yi-5N / m2, eyona nto igqwesileyo yokumisa kunye ne-emulsion stabilizer kwizongezo zokutya.

9) Amanzi agcina i-xanthan gum aneempembelelo ezilungileyo zokugcina amanzi kunye neziphumo ezintsha zogcino ekutyeni.

Izicelo zebakala leXanthan Gum Industrial

1) Kwi-drilling ye-petroleum industry, i-0.5% ye-xanthan gum isisombululo se-aqueous inokugcina i-viscosity yamanzi e-drilling fluid kunye nokulawula iimpawu zayo ze-rheological, ukuze i-viscosity ye-high-speed bits ejikelezayo iphantsi kakhulu, egcina kakhulu ukusetyenziswa kwamandla. , ngelixa kwiindawo zokugaya ezizinzileyo, zinokugcina i-viscosity ephezulu, edlala indima ekuthinteleni ukuwa kwe-wellbore kunye nokuququzelela ukukhutshwa kwelitye elityumkileyo ngaphandle komthombo.

2) Kumzi-mveliso wokutya, kungcono kunezongezo zokutya zangoku ezifana ne-gelatin, i-CMC, i-seaweed gum kunye ne-pectin.Ukongeza i-0.2% ~ 1% kwijusi yenza ukuba ijusi ibe nokubambelela kakuhle, ukunambitheka okulungileyo, kunye nokulawula ukungena kunye nokuhamba;Njengesongezo sesonka, sinokwenza isonka sizinze, sigudileyo, songe ixesha kwaye sinciphise iindleko;Ukusetyenziswa kwe-0.25% ekuzalweni kwesonka, ukuzaliswa kwesandwich yokutya kunye noshukela kunokunyusa i-taste kunye ne-flavour, yenza imveliso ihambe kakuhle, yandise ubomi beshelufu, kwaye iphucule ukuzinza kwemveliso ukufudumeza kunye neqhwa;Kwiimveliso zobisi, ukongeza i-0.1% ～ 0.25% kwi-ayisikrimu inokudlala indima ebalaseleyo yokuzinzisa;Inika ulawulo lwe-viscosity elungileyo ekutyeni okunkonkxiweyo kwaye inokutshintsha indawo yesitatshi.Inxalenye enye ye-xanthan gum inokutshintsha iinxalenye ezi-3-5 zesitashi.Ngelo xesha, i-xanthan gum isetyenziswe ngokubanzi kwi-candy, i-condiments, ukutya okufriziwe kunye nokutya okumanzi.
