Xanthan chịngọm na Hydroxyethyl cellulose (HEC) bụ hydrocolloids nke ejiri ọtụtụ ụlọ ọrụ dị iche iche, ọkachasị na nri, ọgwụ na ngwaahịa nlekọta onwe onye. N'agbanyeghị ụfọdụ myirịta na ngwa ha, ha dị iche na usoro nke kemịkalụ ha, ihe onwunwe ha na arụ ọrụ ha.
1.Chemical Structure:
Xanthan chịngọm: Ọ bụ polysaccharide sitere na gbaa ụka nke carbohydrates, ọkachasị glucose, site na nje Xanthomonas campestris. Ọ nwere ọkpụkpụ azụ nke ihe fọdụrụ glucose nwere eriri akụkụ trisaccharide ugboro ugboro, gụnyere mannose, glucuronic acid, na glucose.
HEC: Hydroxyethyl cellulose bụ ether cellulose na-abụghị ionic nke sitere na cellulose, polysaccharide na-emekarị nke a na-ahụ na mgbidi cell osisi. A na-agbanwe HEC site na iwebata otu hydroxyethyl na ọkpụkpụ azụ cellulose.
2. Solubility:
Xanthan chịngọm: Ọ na-egosipụta oke solubility na ma mmiri oyi na mmiri ọkụ. Ọ na-etolite ngwọta viscous nke ukwuu ọbụlagodi na obere mkpokọta.
HEC: Hydroxyethyl cellulose bụ soluble na mmiri, na solubility ya nwere ike ịdịgasị iche dabere n'ókè nke nnọchi (DS) nke hydroxyethyl otu. DS dị elu na-ebutekarị solubility ka mma.
3. Viscosity:
Xanthan chịngọm: Amara ya maka ihe njiri mara ya pụrụ iche. Ọbụna na obere mkpokọta, xanthan chịngọm nwere ike ịbawanye viscosity nke ngwọta.
HEC: Viscosity nke ngwọta HEC na-adaberekwa na ihe ndị dị ka itinye uche, okpomọkụ, na ọnụ ọgụgụ shear. N'ozuzu, HEC na-egosiputa ihe ndị na-eme ka ọkpụkpụ dị mma, mana viscosity ya dị ala ma e jiri ya tụnyere xanthan chịngọm na nha nha.
4. Omume ịkpa agwa:
Xanthan chịngọm: Ngwọta xanthan chịngọm na-egosipụtakarị omume na-akpachapụ anya, nke pụtara viscosity ha na-ebelata n'okpuru nrụgide shiee wee gbakee ozugbo ewepụrụ nrụgide ahụ.
HEC: N'otu aka ahụ, ngwọta HEC na-egosipụtakwa omume na-akpachapụ anya, ọ bụ ezie na oke nwere ike ịdịgasị iche dabere na ọkwa ọkwa na ọnọdụ ngwọta.
5. ndakọrịta:
Xanthan chịngọm: Ọ dakọtara na ọtụtụ hydrocolloids ndị ọzọ na ihe ndị a na-ejikarị na nri na usoro nlekọta onwe onye. Ọ nwekwara ike ịkwado emulsions.
HEC: Hydroxyethyl cellulose dakọtara na ihe dị iche iche nwere ike iji ya na ihe ndị ọzọ na-eme ka ọ dị elu na ndị na-eme ihe ike iji nweta ihe ndị a chọrọ.
6. Mmekọrịta ya na ihe ndị ọzọ na-agba ume:
Xanthan gum: Ọ na-egosipụta mmetụta synergistic mgbe ejikọtara ya na hydrocolloids ndị ọzọ dị ka guar gum ma ọ bụ igurube bean gum, na-ebute viscosity na nkwụsi ike.
HEC: N'otu aka ahụ, HEC nwere ike mekọrịta ya na ndị ọzọ na-agba agba na ndị polymers, na-enye ụdị dịgasị iche iche na ịmepụta ngwaahịa nwere ụdị ederede na arụmọrụ chọrọ.
Mpaghara 7. Ngwa:
Xanthan chịngọm: Ọ na-achọta ngwa obosara na ngwaahịa nri (dịka ọmụmaatụ, sauces, akwa akwa, ngwaahịa mmiri ara ehi), ngwaahịa nlekọta onwe onye (dịka, lotions, creams, toothpaste), na ngwaahịa ụlọ ọrụ (dịka ọmụmaatụ, mmiri mmiri, agba).
HEC: Hydroxyethyl cellulose bụ nke a na-ejikarị na ngwaahịa nlekọta onwe onye (dịka ọmụmaatụ, shampoos, ịsacha ahụ, ude), ọgwụ (dịka ọmụmaatụ, ngwọta anya, nkwụsị ọnụ), na ihe owuwu (dịka, agba, nrapado).
8. Ọnụ na nnweta:
Xanthan chịngọm: Ọ na-adịkarị ọnụ ọnụ karịa HEC, nke bụ isi n'ihi usoro ịgba ụka na-etinye aka na mmepụta ya. Agbanyeghị, ojiji ya na nnweta ya na-atụnye ụtụ n'ahịa ahịa ya kwụsiri ike.
HEC: Hydroxyethyl cellulose dị ọnụ ala karịa ma e jiri ya tụnyere xanthan gum. A na-emepụta ya n'ọtụtụ ebe site na mgbanwe kemịkalụ nke cellulose, nke dị ukwuu na okike.
mgbe xanthan chịngọm na HEC na-ekerịta ụfọdụ myirịta na ngwa ha dị ka hydrocolloids, ha na-egosipụta ọdịiche dị iche iche na usoro nke kemịkalụ ha, solubility, viscosity, shear-thinning behavior, ndakọrịta, mmekọrịta na ndị ọzọ thickeners, ngwa mpaghara, na ọnụ ahịa. Ịghọta ọdịiche ndị a dị oké mkpa maka ndị na-emepụta ihe ịhọrọ hydrocolloid kachasị mma maka nhazi ngwaahịa kpọmkwem yana njirimara arụmọrụ achọrọ.
