Carboxymethyl cellulose (CMC) yog cov dej-soluble polymer uas feem ntau siv rau ntau yam khoom noj. Nws yog cov khoom noj-qib additive uas yog tsim los ntawm cellulose, uas yog muab los ntawm ntoo pulp, paj rwb, los yog lwm yam nroj tsuag. CMC yog dav siv hauv kev lag luam khoom noj khoom haus ua cov thickener, stabilizer, thiab emulsifier vim nws cov khoom tshwj xeeb. Hauv tsab xov xwm no, peb yuav tham txog cov khoom, kev siv, thiab cov txiaj ntsig ntawm CMC zaub mov qib.

Cov khoom ntawm CMC Food Grade

CMC yog cov hmoov dawb rau cov xim qab zib uas tsis qab, tsis muaj ntxhiab, thiab muaj qaub saj. Nws yog soluble nyob rau hauv dej thiab tsim ib tug ntshiab, viscous tov thaum yaj nyob rau hauv dej. CMC muaj qhov hnyav molecular thiab yog tsim los ntawm cov saw ntev ntawm cellulose molecules. Cov chains no muaj pawg carboxymethyl txuas rau lawv, uas muab CMC nws cov khoom tshwj xeeb.

Ib qho tseem ceeb tshaj plaws ntawm CMC yog nws lub peev xwm los tsim cov gel thaum tov nrog dej. Lub zog gel ntawm CMC nyob ntawm qhov concentration ntawm cov tshuaj thiab qhov hnyav molecular ntawm cov polymer. CMC kuj tseem muaj qib siab ntawm viscosity, uas ua rau nws ua kom cov thickening zoo. Lub viscosity ntawm CMC cov kev daws teeb meem tuaj yeem hloov kho los ntawm kev hloov cov concentration ntawm cov tshuaj.

Lwm yam khoom tseem ceeb ntawm CMC yog nws lub peev xwm los tsim cov emulsion ruaj khov. CMC tuaj yeem txhim kho cov roj-hauv-dej emulsions los ntawm kev tsim cov yeeb yaj kiab tiv thaiv ib puag ncig cov roj tee. Cov yeeb yaj kiab no tiv thaiv cov tee dej los ntawm coalescing thiab pab tswj kev ruaj ntseg ntawm emulsion.

Daim ntawv thov ntawm CMC Food Grade

CMC yog siv nyob rau hauv ntau yam khoom noj khoom haus vim nws cov khoom tshwj xeeb. Qee qhov kev siv feem ntau ntawm CMC zaub mov qib suav nrog:

1. Thickener: CMC feem ntau yog siv los ua cov khoom ua kom tuab hauv cov khoom noj xws li kua ntses, hnav khaub ncaws, thiab gravy. Nws pab txhim kho kev ntxhib los mos thiab lub qhov ncauj ntawm cov khoom no los ntawm kev ua kom lawv cov viscosity.
2. Stabilizer: CMC yog siv los ua tus stabilizer hauv ice cream thiab lwm yam khoom qab zib khov. Nws pab tiv thaiv kev tsim cov dej khov muaju thiab txhim kho qhov smoothness ntawm cov khoom kawg.
3. Emulsifier: CMC yog siv los ua emulsifier hauv cov khoom xws li cov khaub ncaws hnav khaub ncaws thiab mayonnaise. Nws pab kom ruaj khov cov roj-hauv-dej emulsion thiab tiv thaiv kev sib cais ntawm cov khoom xyaw.
4. Binder: CMC yog siv los ua cov ntawv khi hauv cov khoom xws li cov khoom siv nqaij, cov khoom ci, thiab cov cheese ua tiav. Nws pab txhim kho cov kev ntxhib los mos thiab khi cov khoom ntawm cov khoom no.
5. Zaj duab xis-yav dhau los: CMC yog siv los ua zaj duab xis-yav dhau los hauv cov khoom xws li ci ci ci thiab txheej. Nws pab txhim kho cov tsos thiab txee lub neej ntawm cov khoom no.

Cov txiaj ntsig ntawm CMC Food Grade

1. Tus nqi tsim nyog: CMC yog cov khoom noj khoom haus uas muaj txiaj ntsig zoo uas tau siv dav hauv kev lag luam khoom noj. Nws yog pheej yig dua piv rau lwm cov thickeners, stabilizers, thiab emulsifiers.
2. Kev nyab xeeb: CMC raug suav tias muaj kev nyab xeeb rau kev noj los ntawm cov chaw tswj hwm xws li Food and Drug Administration (FDA) thiab European Food Safety Authority (EFSA). Nws tau raug sim ntau yam kev nyab xeeb thiab tau pom zoo siv rau hauv cov khoom noj khoom haus.
3. Versatile: CMC yog ntau yam khoom noj khoom haus ntxiv uas tuaj yeem siv rau ntau yam khoom noj. Nws tuaj yeem siv ua cov thickener, stabilizer, emulsifier, binder, thiab zaj duab xis-yav dhau los, ua rau nws muaj txiaj ntsig zoo hauv ntau yam khoom noj.
4. Tsis muaj tshuaj lom: CMC yog cov khoom noj tsis muaj tshuaj lom uas muaj kev nyab xeeb rau kev noj. Nws tsis absorbed los ntawm lub cev thiab dhau los ntawm lub digestive system unchanged.
