Carboxymethyl cellulose (CMC)bụ ihe anionic mmiri-soluble polymer compound kpụrụ site kemịkalụ mgbanwe nke eke cellulose, na ezi ndim, stabilization, film-akpụ, emulsification na nkwusioru Njirimara. N'ụlọ ọrụ nri, a na-eji CMC eme ihe n'ọtụtụ mmanya, ngwaahịa mmiri ara ehi, ngwaahịa esiri esi na ubi ndị ọzọ. N'ime afọ ndị na-adịbeghị anya, na-amụba anya na nkwụsi ike dị mma na njirimara mmetụta nke mmanya, CMC, dị ka ihe mgbakwunye na-arụ ọrụ, ejirila nwayọọ nwayọọ gosipụta uru pụrụ iche na ụlọ ọrụ mmanya.
1. Usoro ntinye nke CMC na mmanya
Mmanya bụ usoro ngwọta mmiri-ethanol dị mgbagwoju anya nke nwere ụdị acids organic, polyphenols, protein, tartrates, sugars na mineral. N'ihi na-ejighị n'aka anụ ahụ na chemical Njirimara nke mmanya, ọdịda, turbidity, crystallization, agba mgbanwe na nsogbu ndị ọzọ na-adịkarị mfe ime n'oge nchekwa na njem, na-emetụta ya sensory àgwà na ahịa uru. CMC nwere ezigbo solubility na nkwụsi ike. Ọ nwere ike meghachi omume na cations na mmanya na obere mkpokọta, ma n'otu oge ahụ na-emepụta colloid viscous iji dozie nguzozi colloidal nke mmanya, si otú a na-eme ka mmanya ahụ sie ike ma na-egbochi mmiri ozuzo.
2. Isi ọrụ CMC na mmanya
2.1. Na-egbochi kristal tartrate
Potassium tartrate na calcium tartrate na mmanya dị elu na ọdịnaya, na ha dị mfe ịkwanye kristal n'okpuru ọnọdụ okpomọkụ dị ala iji mepụta ọdịda tartar. Ọ bụ ezie na ụdị mmiri ozuzo a na-adịghị egbu egbu na nke na-adịghị njọ, ọ ga-emetụta ihe doro anya nke mmanya ma belata nnabata ndị ahịa. CMC nwere ike igbochi crystallization na mmiri ozuzo nke tartaric acid site na ikpuchi elu nke kristal tartar na igbochi uto ha n'ihu.
2.2. Kwalite nkwụsi ike colloid
Colloid eke dị ka polyphenols, protein, ion metal, wdg dị na mmanya, nke na-enwekarị mmeghachi omume mkpokọta n'okpuru ọnọdụ ụfọdụ, na-ebute turbidity ma ọ bụ ọdịda. CMC nwere ọnụ ọgụgụ buru ibu nke carboxyl dị iche iche na eriri molekụla, nke nwere ike ịmepụta electrostatic na stric egbochi na colloid components na mmanya, mee ka mmanya guzosie ike, na-egbochi mmebi nke colloid enweghị ike kpatara.
2.3. Melite uto na nkwụsi ike
N'ihe mgbakwunye ụfọdụ, CMC nwere ike ịbawanye viscosity nke mmanya, na-eme ka mmanya na-atọ ụtọ karịa ma dị nro. Karịsịa maka mmanya na-egbuke egbuke ma ọ bụ mmanya nwere nnukwu acidity, mgbakwunye nke CMC nwere ike ịhazi ọkwa uto nke ọma ma kwalite ahụmahụ ịṅụ mmanya n'ozuzu ya.
2.4. Mgbochi nke mmiri ozuzo na turbidity
Na mgbakwunye na tartrate, protein na ion metal nwekwara ike ime ka mmiri ozuzo. CMC nwere ike ịmepụta ogige kwụsiri ike na ihe ndị a nwere ike izo mmiri, belata ohere nke turbidity, na ịgbatị ndụ mmanya.
3. Otu esi eji CMC na mmanya
Ekwesịrị iji CMC mee ihe tupu etinye mmanya ahụ, a na-agbakwunyekarị ya mgbe nkwụsi ike oyi gasịrị. Ojiji ya dabere na ihe ndị dị ka ụdị mmanya, nhazi nke ahụ mmanya, na ọnọdụ nchekwa, a na-achịkwa ya n'etiti 100 na 200 mg / L. CMC ga-ebu ụzọ gbasasịa ma gbazee na mmiri ma ọ bụ obere mmanya, wee tinye ya na gbọmgbọm mmanya ahụ dum, kpalie ya nke ọma, nke mere na agbaze kpamkpam ma kesaa ya iji hụ na nkwụsi ike.
Ekwesịrị ịhụ mmanya na-eji CMC na karama ahụ ruo ọtụtụ izu iji kwado arụmọrụ ha kwụsiri ike n'okpuru ọnọdụ nchekwa n'ezie ma zere mmetụta ndị nwere ike ime dị ka mmiri ozuzo ma ọ bụ mmetụta ekpomeekpo.
4. Uru nke iji CMC
Nchedo gburugburu ebe obibi na nchekwa: CMC sitere na cellulose osisi sitere n'okike, adịghị egbu egbu na enweghị mmerụ ahụ, a na-amatakwa ya dị ka ihe mgbakwunye dị mma, n'ikwekọ na ụkpụrụ nchekwa nri nke EU, US FDA na China.
Usoro dị mfe: N'iji ya tụnyere usoro omenala dịka nkwụsị nkwụsịtụ, mgbanwe ion, na mgbakwunye tartrate, iji CMC dị mfe ma ọ dịghị achọ ngwá ọrụ mgbagwoju anya.
Belata oriri ike: Nkwụsi ike oyi ọdịnala na-achọ nchekwa nchekwa dị ala dị ogologo oge, ebe iji CMC nwere ike belata oriri ume nke ukwuu, nke kwekọrọ na ntụziaka nke akwụkwọ ndụ akwụkwọ ndụ na mmepe mmepe.
Adịghị emetụta ekpomeekpo nke mmanya: N'ime ezi uche ojiji oke, CMC agaghị enwe mmetụta dị ịrịba ama na agba, ísì, na uto nke mmanya.
5. Ụkpụrụ na ụkpụrụ dị mkpa
Na mba ụwa, akọwapụtala nke ọma iji CMC eme ihe dị ka ihe mgbakwunye nri. Ọmụmaatụ:
EU: CMC gụnyere na ndepụta mgbakwunye nri EU, yana nọmba E nke E466, enwere ike iji ya na mmanya. Ọnụ ego kachasị elu ga-agbasorịrị ụkpụrụ OIV (International Organisation of Vine and Wine).
US: FDA kwadoro CMC dị ka GRAS (nke a na-ahụkarị dị ka nchekwa) ihe maka ojiji na ihe ọṅụṅụ na nri, gụnyere ihe ọṅụṅụ mmanya fermented.
China: “Ọkọlọtọ ojiji ihe mgbakwunye nri nke mba” (GB 2760) na-enye ohere iji sodium carboxymethyl cellulose mee ihe ọṅụṅụ na ihe ọṅụṅụ na-aba n'anya. Ojiji a kapịrị ọnụ kwesịrị ịtu aka na ụkpụrụ ụlọ ọrụ.
6. Atụmanya ngwa na mmepe mmepe
Ka ndị mmadụ na-eleba anya na nkwụsi ike nke mmanya na nkà na ụzụ na-edozi akwụkwọ ndụ akwụkwọ ndụ, ntinye nke CMC na mmanya ga-aghọwanye ihe. N'otu oge ahụ, na mmepe nke CMC na-arụ ọrụ, dị ka cross-linked CMC ma ọ bụ usoro nhazi na colloid ndị ọzọ, a na-atụ anya na a ga-enweta ihe ngwọta nke ọma na nke ahaziri nke ọma n'ọdịnihu. Na mgbakwunye, CMC nwekwara ike rụọ ọrụ dị ka onye na-ahazi ekpomeekpo na mmanya na-egbu egbu ma ọ bụ mmanya na-adịghị egbu egbu, na-agbasa ebe ngwa ya.
Dị ka ihe mgbakwunye nchekwa, ịrụ ọrụ nke ọma na gburugburu ebe obibi, a na-ejikarị carboxymethyl cellulose eme ihe na ụlọ ọrụ mmanya iji gbochie kristal tartar, kwalite nkwụsi ike colloid, melite uto, na ịgbatị ndụ shelf. The ezi uche ojiji nke CMC nwere ike ọ bụghị nanị melite sensory àgwà na ahịa asọmpi nke mmanya, ma na-enye ụzọ ọhụrụ maka mmanya na-emepụta na-azọpụta ike na ibelata oriri na green mmepụta. Site na ọganihu nke sayensị na teknụzụ yana mgbanwe na ọchịchọ ndị ahịa, iheAtụmanya ngwa nke CMCn'ubi mmanya ga-aba ụba.
