Sodium carboxymethyl cellulose muchikafu

Nhanganyaya

Sodium carboxymethyl cellulose (CMC) chiwedzerwa chekudya chinoshandiswa zvakanyanya chinoshandiswa kuvandudza magadzirirwo, kugadzikana, uye hupenyu hwesherufu hwezvakasiyana zvigadzirwa zvekudya.CMC ichena, isina kunhuwa, poda isina kunaka inotorwa kubva kune cellulose, chikamu chikuru chechirimwa sero madziro.Iyo polysaccharide, zvinoreva kuti inoumbwa nemamorekuru akawanda eshuga akabatanidzwa pamwechete.CMC inoshandiswa mumhando dzakasiyana dzezvigadzirwa zvekudya, zvinosanganisira ice cream, sosi, mapfekero, uye zvinhu zvakabikwa.

Nhoroondo

CMC yakatanga kuvandudzwa mukutanga kwema1900 nemuGermany kemisist, Dr. Karl Schardinger.Akaona kuti nekurapa cellulose nemusanganiswa we sodium hydroxide uye monochloroacetic acid, aigona kugadzira musanganiswa mutsva wainyungudika mumvura kupfuura cellulose.Iyi komputa nyowani yakanzi carboxymethyl cellulose, kana CMC.

Muma1950, CMC yakatanga kushandiswa sechikafu chekuwedzera.Raishandiswa kukobvu nekudzikamisa sosi, madhirezi, uye zvimwe zvinogadzirwa zvekudya.Kubva ipapo, CMC yave yakakurumbira yekuwedzera chikafu nekuda kwekugona kwayo kuvandudza magadzirirwo, kugadzikana, uye hupenyu hwesherufu hwezvigadzirwa zvekudya.

Chemistry

CMC inonzi polysaccharide, zvinoreva kuti inoumbwa nemamorekuru akawanda eshuga akabatana.Chinhu chikuru cheCMC i cellulose, inova ketani refu yemamorekuru eglucose.Kana cellulose inorapwa nemusanganiswa we sodium hydroxide uye monochloroacetic acid, inoumba carboxymethyl cellulose.Iyi nzira inozivikanwa se carboxymethylation.

CMC ivhu chena, risinganhuhwi, risingaravi rinonyungudika mumvura inotonhora uye inopisa.Chinhu chisina muchetura, chisiri-allergenic, uye chisiri-chinogumbura icho chakachengeteka kudyiwa nevanhu.

Function

CMC inoshandiswa mumhando dzakasiyana dzezvigadzirwa zvechikafu kuvandudza magadzirirwo avo, kugadzikana, uye hupenyu hwesherufu.Inoshandiswa seyakakora mumiriri kupa zvigadzirwa zvechikafu chimiro chakakora uye kudzikamisa kuti zvisaparadzane kana kukanganisa.CMC inoshandiswawo se emulsifier kubatsira mafuta nemvura kusanganiswa pamwechete.

Uye zvakare, CMC inoshandiswa kudzivirira ice crystal kuumbwa mune akaomeswa dhizeti, senge ice cream.Inoshandiswawo kuvandudza magadzirirwo ezvakabikwa, zvakadai semakeke nemakiki.

Regulation

CMC inodzorwa neFood and Drug Administration (FDA) muUnited States.Iyo FDA yakaisa mwero wepamusoro wekushandiswa kweCMC mune zvigadzirwa zvekudya.Nhamba yepamusoro yekushandiswa ndeye 0.5% nekurema.

Mhedziso

Sodium carboxymethyl cellulose (CMC) chiwedzerwa chekudya chinoshandiswa zvakanyanya chinoshandiswa kuvandudza magadzirirwo, kugadzikana, uye hupenyu hwesherufu hwezvakasiyana zvigadzirwa zvekudya.CMC ichena, isina kunhuwa, poda isina kunaka inotorwa kubva ku cellulose, chikamu chikuru chechirimwa sero madziro.Iyo polysaccharide, zvinoreva kuti inoumbwa nemamorekuru akawanda eshuga akabatanidzwa pamwechete.CMC inoshandiswa seyakakora mumiriri, emulsifier, uye kudzivirira kuumbwa kwekristaro yechando mumadhizeti akaomeswa nechando.Iyo inodzorwa neFDA muUnited States, ine huwandu hwakanyanya hwekushandisa hwe0.5% nehuremu.
