Ihe ọṅụṅụ mmiri ara ehi acidified na-aghọwanye ewu ewu n'afọ ndị na-adịbeghị anya n'ihi uru ahụike ha na ụtọ pụrụ iche. Otú ọ dị, ihe ọṅụṅụ ndị a nwere ike ịbụ ihe ịma aka iji kwụsie ike, n'ihi na acid dị na mmiri ara ehi nwere ike ime ka ndị na-edozi ahụ pụta ma na-emepụta mkpokọta, na-eduga na sedimentation na nkewa. Otu ụzọ dị irè e si edozi ihe ọṅụṅụ mmiri ara ehi acidified bụ site na iji carboxymethyl cellulose (CMC), polymer soluble mmiri nke nwere ike imekọrịta protein na ihe ndị ọzọ iji mepụta nkwusioru kwụsiri ike. N'isiokwu a, anyị ga-atụle usoro omume nke nkwụsi ike nke mmiri ara ehi acidified nke CMC.

Ọdịdị na Njirimara nke CMC

CMC bụ ihe sitere na cellulose, polymer eke dị na mgbidi cell osisi. A na-eme ya site n'ịgbanwe cellulose na ndị otu carboxymethyl, nke na-eme ka mmiri ya dịkwuo mma na ihe ndị ọzọ. CMC bụ polymer nwere nnukwu alaka nke nwere ọkpụkpụ azụ azụ ogologo ahịrị ahịrị yana ọtụtụ agbụ akụkụ nke otu carboxymethyl. Ogo nke nnọchi (DS) nke CMC na-ezo aka ọnụ ọgụgụ nke carboxymethyl otu kwa cellulose unit, na ọ na-ekpebi ogo nke solubility na viscosity nke CMC.

Usoro mmemme nke CMC n'ịkwụsi ike ihe ọṅụṅụ mmiri ara ehi Acidified

Mgbakwunye CMC na ihe ọṅụṅụ mmiri ara ehi nwere acid nwere ike melite nkwụsi ike ha site n'ọtụtụ usoro:

1. Electrostatic Repulsion: A na-ebo ndị otu carboxymethyl na CMC ebubo na-ezighị ezi ma nwee ike ịmekọrịta na protein ndị nwere ụgwọ dị mma na ihe ndị ọzọ dị na mmiri ara ehi, na-emepụta ike na-asọ oyi nke na-egbochi ndị na-edozi ahụ site na nchịkọta na nhazi. Nke a electrostatic repulsion na-eme ka nkwusioru ahụ guzosie ike ma gbochie sedimentation.
2. Mmekọrịta Hydrophilic: Ọdịdị hydrophilic nke CMC na-enye ya ohere ịmekọrịta ihe na-eme ka mmiri na mmiri na mmiri ara ehi ndị ọzọ na-emekọ ihe, na-eme ka mkpuchi nchebe gburugburu protein na igbochi ha ka ha na ibe ha na-emekọ ihe.
3. Steric Hindrance: The branched Ọdịdị nkeCMCnwere ike ịmepụta mmetụta mgbochi siri ike, na-egbochi ndị na-edozi ahụ ịbịakwute nso na ịmepụta mkpokọta. Ogologo ogologo, nke na-agbanwe agbanwe nke CMC nwekwara ike kechie gburugburu protein ahụ, na-emepụta ihe mgbochi nke na-egbochi ha ịbịakwute ibe ha.
4. Viscosity: Mgbakwunye CMC na ihe ọṅụṅụ mmiri ara ehi acidified nwere ike ime ka viscosity ha dịkwuo elu, nke nwere ike igbochi sedimentation site na ibelata ọsọ ọsọ nke ihe ndị ahụ. Mmụba viscosity nwekwara ike ịmepụta nkwusioru kwụsiri ike site n'ịkwalite mmekọrịta dị n'etiti CMC na ihe ndị ọzọ dị na mmiri ara ehi.

Ihe na-emetụta nkwụsi ike nke ihe ọṅụṅụ mmiri ara ehi Acidified site na CMC

Ịdị irè nke CMC n'ịkwụsị ihe ọṅụṅụ mmiri ara ehi acidified dabere n'ọtụtụ ihe, gụnyere:

1. pH: pH na-emetụta nkwụsi ike nke mmiri ara ehi acidified. N'ụkpụrụ pH dị ala, protein ndị dị na mmiri ara ehi na-agbaji ma na-etolite mkpokọta n'ụzọ dị mfe, na-eme ka nkwụsi ike dịkwuo ike karị. CMC nwere ike ime ka ihe ọṅụṅụ mmiri ara ehi acidified na ụkpụrụ pH dị ala dị ka 3.5, mana arụmọrụ ya na-ebelata na ụkpụrụ pH dị ala.
2. Ntinye uche nke CMC: Nleba nke CMC n'ime mmiri ara ehi na-emetụta njirimara ya. Ọnụ ọgụgụ dị elu nke CMC nwere ike ime ka viscosity dịkwuo elu na nkwụsi ike ka mma, mana oke elu nwere ike ịkpata udidi na ekpomeekpo na-adịghị mma.
3. Ntinye uche nke Protein: Ntinye uche na ụdị protein dị na mmiri ara ehi nwere ike imetụta nkwụsi ike nke ihe ọṅụṅụ ahụ. CMC na-arụ ọrụ nke ọma n'ịkwụsị mmanya na-enweghị protein dị ala, mana ọ nwekwara ike ime ka ihe ọṅụṅụ na-edozi ahụ nwere oke protein dị elu ma ọ bụrụ na irighiri protein dị ntakịrị ma kesaa ya nke ọma.
4. Ọnọdụ nhazi: Ọnọdụ nhazi ejiri mepụta ihe ọṅụṅụ mmiri ara ehi acid nwere ike imetụta nkwụsi ike ya. Ndị agha na-akpụ akpụ na okpomọkụ nwere ike ime ka protein denaturation na nchịkọta, na-eduga na enweghị ntụkwasị obi. Ekwesịrị ịkwalite ọnọdụ nhazi iji belata protein.
