Carboxymethyl cellulose (CMC)is an anionic water-soluble polymer compound yakaumbwa nekugadziriswa kwemakemikari echisikigo cellulose, ine kunaka kukora, kugadzikana, kugadzira firimu, emulsification uye suspension properties. Muindasitiri yechikafu, CMC inoshandiswa zvakanyanya muzvinwiwa, zvigadzirwa zvemukaka, zvakabikwa nemimwe minda. Mumakore achangopfuura, nekuwedzera kutarisisa kugadzikana kwemhando uye hunhu hwewaini, CMC, sechinhu chinowedzera chekuwedzera, yakaratidza zvishoma nezvishoma kukosha kwayo kwakasiyana muindasitiri yewaini.
1. Kushandisa nheyo yeCMC muwaini
Waini yakaoma mvura-ethanol solution system ine zvakasiyana-siyana zveorganic acids, polyphenols, mapuroteni, tartrates, shuga nemaminerari. Nekuda kwekusagadzikana kwemuviri nemakemikari zvimiro zvewaini, kunaya kwemvura, turbidity, crystallization, shanduko yemavara uye mamwe matambudziko anowanzoitika panguva yekuchengetera nekufambisa, zvichikanganisa kunaka kwayo kwekunzwa uye kukosha kwemusika. CMC ine yakanaka solubility uye kugadzikana. Iyo inogona kuita nema cations muwaini panguva yakaderera, uye panguva imwechete inoita viscous colloid kugadzirisa iyo colloidal chiyero chewaini, nekudaro ichidzikamisa waini uye inhibiting kunaya.
2. Basa guru reCMC muwaini
2.1. Kudzivirira tartrate crystallization
Potassium tartrate uye calcium tartrate muwaini yakakwira mune zvemukati, uye zviri nyore kunayisa makristasi pasi pemamiriro ekushisa akadzikama kuti agadzire kunaya kwetartar. Kunyangwe iyi mhando yekunaya isina chepfu uye isingakuvadzi, ichakanganisa kujeka kwewaini uye kuderedza kugamuchirwa kwevatengi. CMC inogona kunyatso kuvharidzira crystallization uye kunaya kwe tartaric acid nekuputira pamusoro pemakristasi etartar uye kutadzisa kuwedzera kwavo kukura.
2.2. Wedzera kugadzikana kwecolloid
Natural colloids senge polyphenols, mapuroteni, simbi ions, nezvimwewo zviripo muwaini, izvo zvinowanzoitika kune aggregation reactions mune mamwe mamiriro, zvichikonzera turbidity kana kunaya kwemvura. CMC ine huwandu hukuru hwemapoka ecarboxyl mucheni yemamorekuru, ayo anogona kuumba electrostatic uye steric chipingamupinyi ane colloid zvikamu muwaini, kudzikamisa chimiro chewaini, uye kudzivirira kuparara kunokonzerwa nekusagadzikana kwecolloid.
2.3. Kuvandudza kuravira uye kuenderana
Pane imwe chiyero chekuwedzera, CMC inogona kuwedzera zvishoma viscosity yewaini, ichiita kuti waini inakidze kutenderedzwa uye kunyorova. Kunyanya yewaini ine muviri wakareruka kana waini ine yakakwira acidity, kuwedzera kweCMC kunogona kunyatso kuenzanisa mwero wekuravira uye kuwedzera ruzivo rwese rwekunwa.
2.4. Kudzivirirwa kwemvura uye turbidity
Pamusoro pe tartrate, mapuroteni uye simbi ions zvinogona kukonzera kunaya. CMC inogona kuumba yakagadzika macomplexes neaya anogona kunaya zvinhu, kuderedza mukana we turbidity, uye kuwedzera hupenyu hwesherufu yewaini.
3. Mashandisiro eCMC muwaini
CMC inofanira kushandiswa waini isati yaiswa mubhodhoro, kazhinji inowedzerwa mushure mekudzikama kwechando. Kushandiswa kwaro kunoenderana nezvinhu zvakaita semhando yewaini, chimiro chemuviri wewaini, uye mamiriro ekuchengetedza, uye kazhinji inodzorwa pakati pe100 ne200 mg/L. CMC inofanira kutanga yakaparadzirwa uye yakanyungudutswa nemvura kana waini shoma, uye zvakaenzana yakawedzerwa kune yose dhiramu yewaini, yakabvongodzwa zvakakwana, kuitira kuti iparadzwe zvachose uye iparadzwe kuti ive nechokwadi chekugadzikana.
Waini dzinoshandisa CMC dzinofanirwa kucherechedzwa mubhodhoro kwemavhiki akati wandei kuratidza kugadzikana kwavo kuita pasi pemamiriro chaiwo ekuchengetera uye kudzivirira zvinogona kuitika senge flocculent kunaya kana flavour mhedzisiro.
4. Zvakanakira kushandisa CMC
Kuchengetedzwa kwezvakatipoteredza uye kuchengetedzeka: CMC inotorwa kubva kune yakasikwa chirimwa cellulose, haina chepfu uye haina kukuvadza, uye inozivikanwa zvakanyanya seyekuwedzera yakachengeteka, inoenderana nemitemo yekuchengetedza chikafu yeEU, US FDA neChina.
Maitiro akareruka: Kuenzaniswa nemaitiro echinyakare akadai sechando kudzikamisa, ion exchange, uye tartrate yekuwedzera, kushandiswa kweCMC kuri nyore uye hakudi michina yakaoma.
Deredzai kushandiswa kwesimba: Kudzikamisa kwechinyakare kunotonhora kunoda kwenguva refu-yakadzika-tembiricha chengetedzo, nepo kushandiswa kweCMC kunogona kuderedza zvakanyanya kushandiswa kwesimba, izvo zvinoenderana negwara regirini uye kusimudzira budiriro.
Haina kukanganisa kunaka kwewaini: Mukati mekushandisa zvine hungwaru, CMC haizove nemhedzisiro yakakosha paruvara, kunhuhwirira, uye kuravira kwewaini.
5. Mitemo yakakodzera nemitemo
Pasi rose, kushandiswa kwemutemo kweCMC sechikafu chekuwedzera kwave kutaurwa zvakajeka. Semuyenzaniso:
EU: CMC inosanganisirwa muEU chikafu chekuwedzera runyorwa, ine nhamba E yeE466, uye inogona kushandiswa muwaini. Huwandu hwekushandisa hwakanyanya hunofanirwa kuenderana nezvinodiwa zveOIV (International Organisation of Vine and Wine).
US: FDA yakatendera CMC se GRAS (inowanzo zivikanwa seyakachengetedzeka) chinhu chekushandisa muzvinwiwa uye chikafu, kusanganisira zvinwiwa zvinodhaka zvakaviriswa.
China: Iyo "National Food Safety Standard Food Additives Usage Standard" (GB 2760) inobvumira sodium carboxymethyl cellulose kushandiswa muzvinwiwa uye zvinwiwa zvinodhaka. Iko kushandiswa chaiko kunofanirwa kureva kune indasitiri zviyero.
6. Tarisiro yekushandisa uye mafambiro ebudiriro
Sezvo vanhu vachinyanya kutarisisa kugadzikana kwewaini uye girini yekugadzirisa tekinoroji, kushandiswa kweCMC muwaini kuchawedzera uye kuwanda. Panguva imwecheteyo, nekuvandudzwa kweCMC inoshanda, senge CMC yakabatana-yakabatana kana masisitimu akaomeswa ane mamwe macolloid, akanyanya kushanda uye akasarudzika waini kudzikamisa mhinduro anotarisirwa kuwanikwa mune ramangwana. Pamusoro pezvo, CMC inogona zvakare kuita basa seanoravira waini muwaini yakaderera-doro kana isiri-doro, ichiwedzera nzvimbo dzayo dzekushandisa.
Seyakachengeteka, inoshanda uye ine hushamwari hwezvakatipoteredza, carboxymethyl cellulose inonyanya kushandiswa muindasitiri yewaini kudzivirira tartar crystallization, kuwedzera kugadzikana kwecolloid, kunatsiridza kuravira, uye kuwedzera hupenyu hwesherufu. Iko kushandiswa zvine musoro kweCMC hakungogone kuvandudza hutano hwekunzwa uye kukwikwidza kwemusika kwewaini, asiwo kupa nzira itsva yevagadziri vewaini kuchengetedza simba uye kuderedza kushandiswa uye kugadzirwa kwegirinhi. Nekufambira mberi kwesainzi uye tekinoroji uye shanduko mukudiwa kwevatengi, iyotarisiro dzekushandisa kweCMCmumunda wewaini zvichapamhidzirwa.
