Xanthan ch?ng?m b? bio gel kachas? elu ugbu a n'ihe gbasara ?gba, nkwusioru, emulsification na nkw?si ike na mba ?wa. ?n? ?g?g? nke pyruvate d? na njedebe nke eriri ak?k? molecular nke xanthan gum nwere mmet?ta d? ukwuu na ihe onwunwe ya. Xanthan ch?ng?m nwere njirimara n'ozuzu nke polymers ogologo yinye, mana ? nwere otu nd? na-ar? ?r? kar?a polymers nk?t? ma na-egosip?ta ihe p?r? iche n'okpuru ?n?d? ?f?d?. Nkwek?r?ta ya na ngw?ta aqueous d? iche iche, na-egosip?ta àgwà d? iche iche n'okpuru ?n?d? d? iche iche.

1. Nkwusioru na emulsifying Njirimara

Xanthan ch?ng?m nwere mmet?ta nkwusioru d? mma na ihe siri ike na-ad?gh? edozi na ?m? irighiri mmiri. Molecules Xanthan ch?ng?m sol nwere ike mep?ta nnukwu njik? helical copolymers, na-etolite gel na-emebi emebi d? ka usoro netw?k? nke nwere ike ?kwado morphology nke ihe siri ike, ?m? irighiri mmiri na af?, na-egosip?ta nkw?si ike emulsifying na ike nkwusioru.

2. Ezigbo solubility mmiri

Xanthan ch?ng?m nwere ike igbari ngwa ngwa na mmiri ma nwee ezigbo mmiri solubility. Kar?s?a soluble na mmiri oyi, ? nwere ike iwep? nhazi mgbagwoju anya ma d? mfe iji. Otú ? d?, n'ihi hydrophilicity siri ike ya, ? b?r? na a na-agbakwunye mmiri ozugbo na-enwegh? mkpali zuru oke, oyi akwa d? n'èzí ga-am?k?r? mmiri ma gbasaa n'ime gel, nke ga-egbochi mmiri ?banye n'ime oyi akwa ma na-emet?ta irè ya. Ya mere, a ghagh? iji ya mee ihe nke ?ma. Gwak?ta xanthan gum nt? nt? ma ? b? ihe mgbakwunye nt? nt? d? ka nnu na shuga, ma jiri nway?? nway?? tinye ya na mmiri na-akpali akpali iji mee ihe ngw?ta maka ojiji.

3. Ngwongwo na-ejup?ta

Ngw?ta Xanthan ch?ng?m nwere njirimara nke itinye uche d? ala na viscosity d? elu (nnyocha nke ngw?ta mmiri 1% b? 100 ugboro nke gelatin), na-eme ka ? b?r? ihe na-ar? ?r? nke ?ma.

4. Pseudoplasticity

Ihe ngw?ta xanthan ch?ng?m nwere nnukwu viscosity n'okpuru ?n?d? static ma ? b? nke d? ala, ma na-egosiputa mbelata nke ukwuu na viscosity n'okpuru ?n?d? d? elu, ma usoro ihe omimi ah? na-agbanwe agbanwe. Mgbe a na-ewep? ike ?kwa akwa, a na-eweghachi viscosity mb? ah? ozugbo. Mmek?r?ta d? n'etiti ike shear na viscosity b? plastik kpamkpam. Pseudoplasticity nke xanthan ch?ng?m b? nke a ma ama, na pseudoplasticity a d? oke irè maka ?kwado nkwusioru na emulsions.

5. Nkw?si ike ka ikpo ?k?

Viscosity nke xanthan ch?ng?m ngw?ta ad?gh? agbanwe nke ?ma na okpom?k?. N'ozuzu, polysaccharides na-enweta mgbanwe viscosity n'ihi kpo oku, mana viscosity nke xanthan gum aqueous solution na-an?gide na-agbanwe agbanwe n'etiti 10-80 ℃. ?b?lagodi ala ?ta ah?h? aqueous ngw?ta ka na-egosip?ta kw?siri ike elu viscosity n'elu a mbara okpom?k? nso. Na-ekpo ?k? 1% xanthan ch?ng?m ngw?ta (nwere 1% potassium chloride) site na 25 ℃ ruo 120 ℃ naan? na-ebelata viscosity ya site na 3%.

6. Nkw?si ike na acidity na alkalinity

Ihe ngw?ta xanthan ch?ng?m kw?siri ike na acidity na alkalinity, na viscosity ya ad?gh? emet?ta n'etiti pH 5-10. Enwere ntak?r? mgbanwe na viscosity mgbe pH na-erugh? 4 na kar?a 11. N'ime pH nke 3-11, ihe kachas? na viscosity kachas? d? iche na-erugh? 10%. Xanthan ch?ng?m nwere ike igbari na ngw?ta acid d? iche iche, d? ka 5% sulfuric acid, 5% nitric acid, 5% acetic acid, 10% hydrochloric acid, na 25% phosphoric acid. Ihe ngw?ta xanthan gum acid nd? a kw?siri ike na ?l? okpom?k? na ? gagh? agbanwe n'?d? mma ruo ?t?t? ?nwa. Xanthan ch?ng?m nwekwara ike igbari na ngw?ta sodium hydroxide ma nwee ihe na-eme ka ? sie ike. Ngw?ta a na-esi na ya p?ta d? nn?? mma na ?l? okpom?k?. Enwere ike imebi Xanthan ch?ng?m site na oxidants siri ike d? ka perchloric acid na persulfate, na mmebi ah? na-abawanye na okpom?k? na-abawanye.
