Carboxymethyl Cellulose (CMC) yakakosha mvura-inonyungudika yepolymer compound iyo inoshandiswa zvakanyanya mukudya, mishonga, makemikari ezuva nezuva, machira nemimwe minda. Muindasitiri yechikafu, imwe yeanonyanya kukosha mashandisirwo eCMC ndeyekukora. Thickeners ikirasi yezvinowedzera zvinowedzera viscosity yemvura pasina kushandura zvakanyanya zvimwe zvinhu zvemvura.
1. Chimiro chemakemikari uye thickening musimboti wecarboxymethyl cellulose
Carboxymethylcellulose inotorwa kubva kune cellulose inoumbwa nekutsiva chikamu chemapoka ehydroxyl (-OH) e cellulose nemapoka ecarboxymethyl (-CH2COOH). Yayo yakakosha dhizaini unit itani inodzokorora ye β-D-glucose. Kuunzwa kwemapoka ecarboxymethyl kunopa CMC hydrophilicity, ichipa kunyungudika kwakanaka uye kugona kukora mumvura. Kukora kwayo musimboti kunonyanya kubva pane zvinotevera pfungwa:
Kuzvimba mhedzisiro: CMC ichazvimba mushure mekutora mamorekuru emvura mumvura, ichigadzira network network, kuitira kuti mamorekuru emvura anotorwa muchimiro chayo, achiwedzera viscosity yehurongwa.
Charge effect: Mapoka ecarboxyl muCMC anozoiswa ionized mumvura kuti abudise mhosva dzisina kunaka. Aya mapoka anochajiswa anozogadzira electrostatic repulsion mumvura, zvichiita kuti cheni dzemamorekuru dziburitse uye kugadzira mhinduro ine high viscosity.
Kureba kweketani uye kutarisisa: Kureba kweketani uye kugadziriswa kwekugadzirisa kweCMC mamorekuru kuchakanganisa kukora kwayo. Kazhinji kutaura, kukwira kwehuremu hwema molecular, kunowedzera viscosity yemhinduro; panguva imwe chete, iyo yakakwirira yehutano hwekugadzirisa, iyo viscosity yegadziriro inowedzerawo.
Molecular cross-linking: Kana CMC yanyungudutswa mumvura, nekuda kwekuyambuka-kubatanidza pakati pemamorekuru uye kuumbwa kwetiweki chimiro, mamorekuru emvura anoganhurirwa kune dzakananga nzvimbo, zvichikonzera kudzikira kwekuyerera kwemhinduro, zvichiratidza thickening effect.
2. Kushandiswa kwecarboxymethyl cellulose muindasitiri yezvekudya
Muindasitiri yezvekudya, carboxymethylcellulose inoshandiswa zvakanyanya seyakakora. Aya anotevera ndiwo mamwe akajairika application mamiriro:
Zvinwiwa uye zvigadzirwa zvemukaka: Mune zvinwiwa zvemichero uye lactobacillus zvinwiwa, CMC inogona kuwedzera viscosity yechinwiwa, kuvandudza kuravira uye kuwedzera hupenyu hwesherufu. Kunyanya mune yakaderera-mafuta uye isina-mafuta-isina zvigadzirwa zvemukaka, CMC inogona kutsiva chikamu chemafuta emukaka uye kuvandudza magadzirirwo uye kugadzikana kwechigadzirwa.
Masosi uye macondiments: Mukupfeka saradhi, muto wematomatisi uye soy muto, CMC inoita seyakakora uye inomisa mumiriri kuti ivandudze kufanana kwechigadzirwa, kudzivirira delamination, uye kuita kuti chigadzirwa chiwedzere kugadzikana.
Ice cream uye zvinwiwa zvinotonhora: Kuwedzera CMC kune ice cream uye zvinwiwa zvinotonhora zvinogona kuvandudza chimiro chechigadzirwa, chichiita kuti chiwedzere uye chiwedzere elastic, kudzivirira kuumbwa kweaizi makristasi nekuvandudza kuravira.
Chingwa uye zvigadzirwa zvakabikwa: Muzvigadzirwa zvakabikwa zvakaita sechingwa nemakeke, CMC inoshandiswa sekuvandudza mukanyiwa kuwedzera kuwedzera kwehupfu, kuita kuti chingwa chipfave, uye kuwedzera hupenyu hwesherufu.
3. Kumwe kukora kwekushandiswa kwecarboxymethyl cellulose
Pamusoro pekudya, carboxymethylcellulose inowanzoshandiswa seyakakura mumishonga, cosmetics, makemikari ezuva nezuva uye mamwe maindasitiri. Semuyenzaniso:
Indasitiri yemishonga: Mumishonga, CMC inowanzo shandiswa kukora masirapu, makapisi, uye mahwendefa, kuitira kuti mishonga ive nani kuumba uye kuparara kwemhedzisiro, uye inogona kuvandudza kugadzikana kwemishonga.
Zvizoro uye makemikari ezuva nezuva: Mumakemikari ezuva nezuva akadai semazino, shampoo, gel yekugeza, nezvimwewo, CMC inogona kuwedzera kuenderana kwechigadzirwa, kuvandudza ruzivo rwekushandisa, uye kugadzira yunifomu yekunamira uye yakagadzikana.
4. Kuchengetedzwa kwecarboxymethyl cellulose
Kuchengeteka kwecarboxymethylcellulose kwakasimbiswa nezvidzidzo zvakawanda. Sezvo CMC inotorwa kubva kune yakasikwa cellulose uye isina kugayiwa uye kunyudzwa mumuviri, kazhinji haina kukanganisa kwakaipa pahutano hwevanhu. Ose ari maviri World Health Organisation (WHO) neJoint Expert Committee on Food Additives (JECFA) anoiisa sechinhu chakachengeteka chekuwedzera chikafu. Pamushonga unonzwisisika, CMC haiburitse maitiro ehupfu uye ine mamwe mafuta uye laxative mhedzisiro pamatumbo. Nekudaro, kudyisa zvakanyanya kunogona kukonzera kusagadzikana kwegastrointestinal, saka iyo yakatemerwa dosage zviyero zvinofanirwa kunyatso kuteedzerwa mukugadzirwa kwechikafu.
5. Zvakanakira uye zvisingabatsiri zve carboxymethylcellulose
Carboxymethylcellulose ine zvakanakira uye zvinogumira seyakakora:
Zvakanakira: CMC ine mvura yakanaka solubility, kugadzikana kwemafuta uye kugadzikana kwekemikari, inodzivirira asidhi uye alkali, uye haisi nyore kuderedzwa. Izvi zvinobvumira kuti ishandiswe munzvimbo dzakasiyana-siyana dzekugadzirisa.
Zvakaipa: CMC inogona kuita viscous zvakanyanya pakakwirira uye haina kukodzera kune zvese zvigadzirwa. CMC inoshatisa munzvimbo ine acidic, zvichikonzera kudzikira mukukora kwayo. Kungwarira kunodiwa kana uchiishandisa muzvinwiwa zvine acidic kana chikafu.
Seyakakora yakakosha, carboxymethylcellulose inoshandiswa zvakanyanya muchikafu, mushonga, zvizorwa uye mimwe minda nekuda kwekunyungudika kwayo kwemvura, kukora uye kugadzikana. Kuwedzera kwayo kwepamusoro uye kuchengetedzeka kunoita kuti ive inowanzoshandiswa muindasitiri yemazuva ano. Nekudaro, kushandiswa kweCMC kunodawo kudzorwa nesainzi zvichienderana nezvinodiwa uye dosage zviyero kuti ive nechokwadi chekugonesa kuita kwayo uye kuchengetedza chikafu.
