I-Carboxymethyl cellulose (CMC)i-anionic water-soluble polymer compound eyakhiwe ukuguqulwa kwamakhemikhali we-cellulose yemvelo, enokuqina okuhle, ukuqiniswa, ukwakheka kwefilimu, i-emulsification kanye nezakhiwo zokumiswa. Embonini yokudla, i-CMC isetshenziswa kabanzi eziphuzweni, emikhiqizweni yobisi, emikhiqizweni ebhakiwe neminye imikhakha. Eminyakeni yamuva, ngokunaka okwandayo ekuzinzeni kwekhwalithi kanye nezici zezinzwa zewayini, i-CMC, njengesithasiselo esisebenzayo, ibonise kancane kancane inani layo eliyingqayizivele embonini yewayini.
1. Umgomo wokusetshenziswa kwe-CMC ewayinini
Iwayini liwuhlelo oluyinkimbinkimbi lwesisombululo samanzi-ethanol oluqukethe izinhlobonhlobo ze-organic acid, ama-polyphenols, amaprotheni, ama-tartrates, ushukela namaminerali. Ngenxa yezakhiwo ezingazinzile zomzimba namakhemikhali ewayini, imvula, i-turbidity, crystallization, izinguquko zombala nezinye izinkinga zivame ukwenzeka ngesikhathi sokugcinwa nokuthutha, okuthinta ikhwalithi yayo yezinzwa kanye nenani lemakethe. I-CMC inokunyibilika okuhle nokuzinza. Ingasabela ngama-cations ewayini ekugxilweni okuphansi, futhi ngesikhathi esifanayo yenza i-viscous colloid ukuze ilungise ibhalansi ye-colloidal yewayini, ngaleyo ndlela igxilise iwayini futhi ivimbele imvula.
2. Iqhaza elikhulu le-CMC ewayinini
2.1. Ukuvimbela crystallization tartrate
I-Potassium tartrate kanye ne-calcium tartrate ewayinini kuphezulu ngokuqukethwe, futhi kulula ukuletha amakristalu ngaphansi kwezimo eziphansi zokushisa ukuze zakhe imvula ye-tartar. Nakuba lolu hlobo lwemvula lungenabo ubuthi futhi lungenabungozi, luzophazamisa ukucaca kwewayini futhi lunciphise ukwamukelwa kwabathengi. I-CMC inganqanda ngempumelelo ukucwebezela kanye nemvula ye-tartaric acid ngokumboza ingaphezulu lamakristalu e-tartar futhi ivimbele ukukhula kwawo okuqhubekayo.
2.2. Thuthukisa ukuzinza kwe-colloid
Ama-colloid emvelo afana nama-polyphenols, amaprotheni, ama-ion ensimbi, njll. akhona ewayinini, athambekele ekuhlanganeni ngaphansi kwezimo ezithile, okuholela ku-turbidity noma imvula. I-CMC iqukethe inqwaba yamaqembu e-carboxyl ochungechungeni lwemolekyuli, engakha isithiyo se-electrostatic kanye ne-steric nezingxenye ze-colloid ewayinini, iqinise ukwakheka kwewayini, futhi ivimbele ukuwohloka okubangelwa ukungazinzi kwe-colloid.
2.3. Thuthukisa ukunambitheka nokuvumelana
Ngenani elithile lokwengeza, i-CMC ingakhuphula kancane i-viscosity yewayini, yenze iwayini lizwakale libe yindilinga futhi lithambile. Ikakhulukazi kumawayini anomzimba okhanyayo noma amawayini ane-asidi ephezulu, ukungezwa kwe-CMC kungalinganisa ngempumelelo izinga lokunambitha futhi kuthuthukise umuzwa wokuphuza uwonke.
2.4. Ukuvinjwa kwemvula kanye ne-turbidity
Ngaphezu kwe-tartrate, amaprotheni nama-ion ensimbi nawo angabangela imvula. I-CMC ingakha izakhiwo ezizinzile nalezi zici zezulu ezingaba khona, inciphise amathuba okuba nemfucumfucu, futhi inwebe isikhathi seshelufu sewayini.
3. Isetshenziswa kanjani i-CMC ewayinini
I-CMC kufanele isetshenziswe ngaphambi kokuba iwayini lifakwe ebhodleleni, ngokuvamile lifakwa ngemva kokuqiniswa okubandayo. Ukusetshenziswa kwalo kuncike ezintweni ezifana nohlobo lwewayini, ukwakheka kwendikimba yewayini, kanye nezimo zokuligcina, futhi ngokuvamile lilawulwa phakathi kuka-100 no-200 mg/L. I-CMC kufanele iqale ihlakazwe futhi ihlakazwe ngamanzi noma inani elincane lewayini, bese ifakwa ngokulinganayo kuwo wonke umgqomo wewayini, igovuze kahle, ukuze ihlakazwe ngokuphelele futhi isatshalaliswe ukuze kuqinisekiswe umphumela wokuzinza.
Amawayini asebenzisa i-CMC kufanele abhekwe ebhodleleni amaviki ambalwa ukuze kuqinisekiswe ukusebenza kwawo okuzinzile ngaphansi kwezimo zangempela zokulondoloza futhi agweme imiphumela engemihle engaba khona njengemvula egelezayo noma imithelela yokunambitheka.
4. Izinzuzo zokusebenzisa i-CMC
Ukuvikelwa kwemvelo nokuphepha: I-CMC ithathwe ku-cellulose yezitshalo zemvelo, ayinabo ubuthi futhi ayinabungozi, futhi yaziwa kabanzi njengesithasiselo esiphephile, ngokuhambisana namazinga okuphepha kokudla e-EU, i-US FDA ne-China.
Inqubo elula: Uma kuqhathaniswa nezindlela zendabuko ezifana nokuqiniswa kweqhwa, ukushintshaniswa kwe-ion, nokwengezwa kwe-tartrate, ukusetshenziswa kwe-CMC kulula futhi akudingi imishini eyinkimbinkimbi.
Yehlisa ukusetshenziswa kwamandla: Ukuzinzisa okubandayo okujwayelekile kudinga isitoreji sesikhathi eside sezinga lokushisa eliphansi, kuyilapho ukusetshenziswa kwe-CMC kunganciphisa kakhulu ukusetshenziswa kwamandla, okuhambisana nesiqondiso sentuthuko eluhlaza nokuqhubekayo.
Ayithinti ukunambitheka kwewayini: Phakathi kwebanga lokugxilisa ingqondo lokusetshenziswa okunengqondo, i-CMC ngeke ibe nomthelela obalulekile embaleni, iphunga, kanye nakunambitheka kwewayini.
5. Imithethonqubo nezindinganiso ezifanele
Emazweni ngamazwe, ukusetshenziswa okusemthethweni kwe-CMC njengesithasiselo sokudla kubekwe ngokucacile. Ngokwesibonelo:
I-EU: I-CMC ifakwe ohlwini lwe-EU lwezithako zokudla, nenombolo E ye-E466, futhi ingasetshenziswa ewayinini. Inani eliphezulu lokusetshenziswa kufanele lihambisane nezindinganiso ezifanele ze-OIV (Inhlangano Yomhlaba Wonke Yezivini Newayini).
E-US: I-FDA igunyaze i-CMC njengento ye-GRAS (evame ukubonwa njengephephile) ukuze isetshenziswe eziphuzweni nasekudleni, okuhlanganisa nophuzo oludakayo olubilisiwe.
I-China: "I-National Food Safety Standard Yokusebenzisa Izithasiselo Zokudla" (GB 2760) ivumela i-sodium carboxymethyl cellulose ukuthi isetshenziswe eziphuzweni naseziphuzweni ezidakayo. Ukusetshenziswa okuqondile kufanele kubhekisele kumazinga womkhakha.
6. Amathemba okufaka isicelo kanye nezindlela zokuthuthuka
Njengoba abantu benaka kakhulu ukuzinza kwekhwalithi yewayini kanye nobuchwepheshe bokucubungula okuluhlaza, ukusetshenziswa kwe-CMC ewayini kuzokwanda kakhulu. Ngaso leso sikhathi, ngokuthuthukiswa kwe-CMC esebenzayo, efana ne-CMC exhumene noma amasistimu ayinhlanganisela namanye ama-colloid, izixazululo ezisebenza kahle kakhulu neziqondene nomuntu siqu zokuzinzisa iwayini kulindeleke ukuthi zizuzwe esikhathini esizayo. Ukwengeza, i-CMC ingase futhi idlale indima njengesilawuli sokunambitha ewayinini elinotshwala obuncane noma angenabo utshwala, yandise izindawo zayo zokusebenza.
Njengesengezo esiphephile, esisebenzayo futhi esinobungani bemvelo, i-carboxymethyl cellulose isetshenziswa kakhulu embonini yewayini ukuvimbela i-tartar crystallization, ukuthuthukisa ukuzinza kwe-colloid, ukuthuthukisa ukunambitheka, nokwelula impilo yeshalofu. Ukusetshenziswa okunengqondo kwe-CMC akukwazi nje ukuthuthukisa ikhwalithi yezinzwa kanye nokuncintisana kwemakethe kwewayini, kodwa futhi kunikeze indlela entsha kubakhiqizi bewayini ukuze bonge amandla futhi banciphise ukusetshenziswa nokukhiqizwa okuluhlaza. Ngokuthuthuka kwesayensi nobuchwepheshe kanye nezinguquko ezidingweni zabathengi, iamathemba okufaka isicelo se-CMCensimini yewayini kuyoba banzi.
