Carboxymethyl cellulose (CMC)yog ib qho anionic dej-soluble polymer compound tsim los ntawm tshuaj hloov kho ntawm natural cellulose, nrog zoo thickening, stabilization, film-forming, emulsification thiab ncua kev kawm ntawv. Hauv kev lag luam zaub mov, CMC tau siv dav hauv dej haus, khoom noj siv mis, khoom ci thiab lwm yam haujlwm. Nyob rau hauv xyoo tas los no, nrog rau kev mloog zoo rau qhov zoo stability thiab sensory yam ntxwv ntawm caw, CMC, raws li ib tug functional additive, tau maj mam qhia nws tus nqi tshwj xeeb nyob rau hauv wine kev lag luam.
1. Kev siv txoj cai ntawm CMC hauv cawv
Wine yog ib qho dej-ethanol daws teeb meem uas muaj ntau yam organic acids, polyphenols, proteins, tartrates, suab thaj thiab cov zaub mov. Vim lub cev tsis ruaj tsis khov thiab tshuaj lom neeg ntawm cawv, nag lossis daus, turbidity, crystallization, xim hloov thiab lwm yam teeb meem yuav tshwm sim thaum lub sij hawm cia thiab tsheb thauj mus los, cuam tshuam rau nws qhov kev xav zoo thiab cov nqi lag luam. CMC muaj zoo solubility thiab stability. Nws tuaj yeem cuam tshuam nrog cations hauv cawv ntawm qhov tsis tshua muaj siab, thiab tib lub sijhawm tsim cov viscous colloid los kho cov colloidal tshuav nyiaj li cas ntawm cawv, yog li stabilizing cov cawv thiab inhibiting nag lossis daus.
2. Lub luag haujlwm tseem ceeb ntawm CMC hauv cawv
2.1. Tiv thaiv tartrate crystallization
Potassium tartrate thiab calcium tartrate nyob rau hauv caw yog siab nyob rau hauv cov ntsiab lus, thiab lawv yog ib qho yooj yim rau precipitate crystals nyob rau hauv qis kub tej yam kev mob los tsim tartar nag lossis daus. Txawm hais tias hom nag lossis daus no tsis muaj tshuaj lom thiab tsis muaj mob, nws yuav cuam tshuam rau qhov pom tseeb ntawm cov cawv thiab txo cov neeg siv khoom. CMC tuaj yeem cuam tshuam cov crystallization thiab nag lossis daus ntawm tartaric acid los ntawm txheej txheej ntawm tartar crystals thiab cuam tshuam lawv txoj kev loj hlob ntxiv.
2.2. Txhim kho colloid stability
Ntuj colloids xws li polyphenols, proteins, hlau ions, thiab lwm yam muaj nyob rau hauv cawu cub, uas yog nquag mus rau aggregation tshua nyob rau hauv tej yam kev mob, ua rau turbidity los yog nag lossis daus. CMC muaj ntau pawg carboxyl nyob rau hauv cov saw hlau molecular, uas tuaj yeem tsim electrostatic thiab steric hindrance nrog cov colloid Cheebtsam hauv cov cawv, stabilize cov qauv cawv, thiab tiv thaiv kev puas tsuaj los ntawm colloid instability.
2.3. Txhim kho saj thiab sib xws
Ntawm ib qho ntxiv, CMC tuaj yeem ua kom cov viscosity ntawm cawv me ntsis, ua rau cov cawv txiv hmab ntau sib npaug thiab mellow. Tshwj xeeb tshaj yog rau lub teeb-lub cev wines los yog wines nrog high acidity, qhov sib ntxiv ntawm CMC tuaj yeem sib npaug ntawm cov saj thiab txhim kho kev haus dej tag nrho.
2.4. Inhibition ntawm nag lossis daus thiab turbidity
Ntxiv nrog rau tartrate, cov proteins thiab hlau ions kuj tuaj yeem ua rau nag lossis daus. CMC tuaj yeem tsim cov chaw ruaj khov nrog cov peev txheej nag lossis daus, txo qhov muaj peev xwm ntawm turbidity, thiab txuas ntxiv lub txee lub neej ntawm cawv.
3. Yuav siv CMC li cas hauv cawv
CMC yuav tsum tau siv ua ntej lub raj mis, feem ntau ntxiv tom qab txias stabilization. Nws txoj kev siv yog nyob ntawm yam xws li hom cawv, cov qauv ntawm lub cev cawv, thiab kev cia khoom, thiab feem ntau tswj tau ntawm 100 thiab 200 mg / L. CMC yuav tsum tau ua ntej dispersed thiab yaj nrog dej los yog ib tug me me npaum li cas ntawm cawu cub, thiab ces sib npaug zos rau tag nrho cov thoob dej caw, nplawm kom huv si, kom nws yog kiag li yaj thiab muab faib mus rau hauv lub stability nyhuv.
Wines siv CMC yuav tsum tau soj ntsuam nyob rau hauv lub raj mis rau ob peb lub lis piam kom paub meej tias lawv ruaj khov kev ua tau zoo nyob rau hauv lub sij hawm cia tej yam kev mob thiab tsis txhob muaj kev phiv xws li flocculent nag lossis daus.
4. Qhov zoo ntawm kev siv CMC
Kev tiv thaiv ib puag ncig thiab kev nyab xeeb: CMC yog muab los ntawm cov nroj tsuag ntuj cellulose, tsis muaj tshuaj lom thiab tsis muaj kev phom sij, thiab tau lees paub dav dav tias yog cov khoom noj muaj kev nyab xeeb, raws li cov qauv kev nyab xeeb ntawm EU, US FDA thiab Tuam Tshoj.
Cov txheej txheem yooj yim: Muab piv nrog cov txheej txheem ib txwm muaj xws li khov stabilization, ion pauv, thiab tartrate ntxiv, kev siv CMC yog qhov yooj yim dua thiab tsis xav tau cov cuab yeej nyuaj.
Txo kev siv hluav taws xob: Kev ua kom txias txias yuav tsum tau khaws cia rau lub sijhawm ntev, thaum kev siv CMC tuaj yeem txo qis kev siv hluav taws xob ntau, uas yog nyob rau hauv txoj kab nrog kev taw qhia ntawm ntsuab thiab kev txhim kho ruaj khov.
Tsis cuam tshuam rau qhov tsw ntawm cawv: Hauv qhov tsim nyog siv ntau yam, CMC yuav tsis muaj qhov cuam tshuam loj rau xim, aroma, thiab saj ntawm cawv.
5. Cov kev cai thiab cov qauv tsim nyog
Thoob ntiaj teb, kev cai lij choj siv CMC raws li cov khoom noj khoom haus tau hais meej meej. Piv txwv li:
EU: CMC suav nrog hauv EU cov npe khoom noj ntxiv, nrog tus lej E ntawm E466, thiab tuaj yeem siv rau hauv cawv. Qhov nyiaj siv ntau tshaj plaws yuav tsum ua raws li cov qauv txheej txheem ntawm OIV (International Organization of Vine and Wine).
Teb Chaws Asmeskas: FDA pom zoo CMC ua GRAS (feem ntau lees paub tias muaj kev nyab xeeb) cov khoom siv rau hauv cov dej haus thiab zaub mov, suav nrog cov dej cawv fermented.
Tuam Tshoj: "National Food Safety Standard Food Additives Usage Standard" (GB 2760) tso cai rau sodium carboxymethyl cellulose siv rau hauv cov dej haus thiab dej cawv. Kev siv tshwj xeeb yuav tsum xa mus rau cov qauv kev lag luam.
6. Daim ntawv thov kev cia siab thiab kev txhim kho tiam sis
Raws li tib neeg them nyiaj ntau dua rau kev ruaj ntseg zoo ntawm cawv thiab ntsuab ua tshuab, daim ntawv thov CMC hauv cawv yuav dhau los ua ntau dua. Nyob rau tib lub sijhawm, nrog rau kev txhim kho ntawm CMC kev ua haujlwm, xws li kev sib txuas ntawm CMC lossis cov tshuab sib txuas nrog lwm cov colloids, kev ua haujlwm zoo dua thiab cov kev daws teeb meem ntawm tus kheej yuav tsum tau ua tiav yav tom ntej. Tsis tas li ntawd, CMC kuj tseem tuaj yeem ua lub luag haujlwm ua tus tswj hwm tsw hauv cawv lossis cawv tsis muaj cawv, nthuav dav nws thaj chaw thov.
Raws li kev nyab xeeb, muaj txiaj ntsig zoo thiab ib puag ncig tus phooj ywg additive, carboxymethyl cellulose feem ntau yog siv hauv kev lag luam cawv los tiv thaiv tartar crystallization, txhim khu kev ruaj ntseg colloid, txhim kho saj, thiab ntev txee lub neej. Kev siv CMC tsis tuaj yeem tsuas yog txhim kho qhov kev xav zoo thiab kev lag luam kev sib tw ntawm cov cawv txiv hmab, tab sis kuj muab txoj hauv kev tshiab rau cov tuam txhab cawv kom txuag tau lub zog thiab txo kev noj thiab kev tsim ntsuab. Nrog rau kev nce qib ntawm kev tshawb fawb thiab thev naus laus zis thiab kev hloov pauv ntawm cov neeg siv khoom xav tau, lubdaim ntawv thov kev cia siab ntawm CMCnyob rau hauv lub teb ntawm cawu cub yuav dav.
