Xanthan gum ma le Hydroxyethyl cellulose (HEC) e lua hydrocolloids fa'aaogaina tele i pisinisi eseese, aemaise i mea'ai, vaila'au, ma mea tau tausiga a le tagata lava ia.E ui lava i nisi o mea e tutusa ai a latou talosaga, e ese lava i le tulaga o latou fausaga kemisi, meatotino, ma galuega.
1. Fa'atonuga:
Xanthan gum: O se polysaccharide e maua mai i le faʻafefe o gaʻo, aemaise lava kulukose, e le siama Xanthomonas campestris.O lo'o i ai se ivi pito i tua o toega o le kulukose ma filifili itu o trisaccharide toe fai iunite, e aofia ai le mannose, glucuronic acid, ma le kulukose.
HEC: Hydroxyethyl cellulose ose ether cellulose non-ionic e maua mai le cellulose, o se polysaccharide fa'alenatura o lo'o maua i puipui sela o laau.E fa'aleleia le HEC e ala i le fa'aofiina o vaega o le hydroxyethyl i luga ole ponaivi o le cellulose.
2.Solubility:
Xanthan gum: E fa'aalia le solubility maualuga i vai malulu ma vai vevela.E fai ni vaifofo sili ona viscous e tusa lava pe maualalo le fa'atonuga.
HEC: Hydroxyethyl cellulose e solu i le vai, ma o lona solubility e mafai ona fesuisuiai e faalagolago i le tikeri o le suitulaga (DS) o vaega hydroxyethyl.Ole maualuga ole DS e masani ona maua ile sili atu ole solubility.
3. Viscosity:
Xanthan gum: E lauiloa mo ona uiga mafiafia uiga ese.E tusa lava pe maualalo le faʻaogaina, o le xanthan gum e mafai ona faʻateleina le viscosity o fofo.
HEC: O le viscosity o fofo HEC e fa'alagolago fo'i i mea e pei o le fa'atonuga, vevela, ma le fua o le sile.E masani lava, o le HEC o loʻo faʻaalia lelei mea mafiafia, ae o lona viscosity e maualalo pe a faʻatusatusa i le xanthan gum i faʻatusatusaga tutusa.
4. Fa'amama le Amio:
Xanthan gum: O vaifofo o le xanthan gum e masani ona fa'aalia ai amioga fa'amama fa'amama, o lona uiga e fa'aitiitia le viscosity i lalo o le mamafa o le sile ma toe fa'aleleia pe a aveese le fa'alavelave.
HEC: E fa'apena fo'i, e fa'aalia fo'i e vaifofo a le HEC le amio fa'amamafa, e ui e mafai ona fesuisuia'i le lautele e fa'atatau i le vasega ma'oti ma tulaga o fofo.
5. Feso'ota'i:
Xanthan gum: E fetaui lelei ma le tele o isi hydrocolloids ma mea e masani ona faʻaaogaina i meaʻai ma tausiga a le tagata lava ia.E mafai foi ona faʻamautu emulsions.
HEC: Hydroxyethyl cellulose e fetaui lelei ma mea eseese ma e mafai ona faʻaoga faʻatasi ma isi mea mafiafia ma faʻamautu e ausia ai mea faʻapitoa e manaʻomia.
6.Synergy ma isi mea mafiafia:
Xanthan gum: E fa'aalia a'afiaga fa'atasi pe a tu'ufa'atasia ma isi hydrocolloids e pei ole guar gum po'o se akerise pulu pi, e fa'atupu ai le fa'aleleia o le viscosity ma le mautu.
HEC: E fa'apena fo'i, e mafai e le HEC ona tu'ufa'atasia ma isi mafiafia ma polymers, e tu'uina atu ai le agava'a i le fa'atupuina o oloa fa'atasi ai ma mea fa'apitoa ma mea e mana'omia.
7. Avanoa Talosaga:
Xanthan gum: E maua ai le tele o fa'aoga i mea'ai (fa'ata'ita'iga, sosi, la'ei, mea tau susu), mea mo le tausiga o le tagata lava ia (fa'ata'ita'iga, lotion, kulimi, fulunifo), ma mea tau alamanuia (fa'ata'ita'iga, vai vili, vali).
HEC: O le hydroxyethyl cellulose e masani ona fa'aoga i oloa tau le tagata lava ia (fa'ata'ita'iga, shampoos, fufulu o le tino, kulimi), vaila'au (fa'ata'ita'iga, vaifofo mata, tu'u gutu), ma mea faufale (fa'ata'ita'iga, vali, mea fa'apipi'i).
8. Tau ma Avanoa:
Xanthan gum: E masani ona sili atu le taugata pe a faʻatusatusa i le HEC, e mafua ona o le faʻafefeteina o loʻo aʻafia i lona gaosiga.Ae ui i lea, o lona fa'aogaina lautele ma le avanoa e saofagā i lona sapalai mautu i maketi.
HEC: O le hydroxyethyl cellulose e tau sili atu ona taugofie pe a faatusatusa i le xanthan gum.E gaosia lautele e ala i suiga fa'a-kemikolo o le cellulose, lea e tele i le natura.
a'o fa'asoa le xanthan gum ma le HEC ni mea e tutusa ai a latou talosaga e pei o hydrocolloids, latou te fa'aalia le eseesega ma'oti i tulaga o latou fausaga kemikolo, solubility, viscosity, shear-thinning behavior, compatibility, synergy with other thickeners, application areas, and cost.O le malamalama i nei eseesega e taua tele mo tagata faʻapipiʻi e filifili ai le hydrocolloid sili ona talafeagai mo faʻasologa o oloa faʻapitoa ma uiga faʻatinoga e manaʻomia.
