Sodium carboxymethyl cellulose e nhamba

Nhanganyaya

Sodium carboxymethyl cellulose (CMC) inoshandiswa zvakanyanya chikafu chekuwedzera ine nhamba E466. Iyo chena, isina kunhuwa, isina kunaka poda iyo inoshandiswa seyakakora uye inodzikamisa mune zvakawanda zvigadzirwa zvekudya. CMC inotorwa kubva ku cellulose, polysaccharide inongoitika inowanikwa muzvirimwa. Inogadzirwa nekuita cellulose ine sodium hydroxide uye monochloroacetic acid. CMC inoshandiswa mumhando dzakasiyana dzezvigadzirwa zvekudya, zvinosanganisira aizikirimu, mapfekero esaladhi, sosi, uye zvinhu zvakabikwa. Inoshandiswawo mumishonga, cosmetics, uye detergents.

Mushonga Wemakemikari

Sodium carboxymethyl cellulose ndeye anionic polysaccharide inoumbwa nekudzokorora zvikamu zveD-glucose uye D-mannose. Chimiro chemakemikari cheCMC chinoratidzwa muMufananidzo 1. Zvisungo zvinodzokorora zvakabatanidzwa pamwe chete neglycosidic bonds. Iwo mapoka ecarboxymethyl akabatanidzwa kumapoka ehydroxyl eglucose uye mannose units. Izvi zvinopa molecule mhosva yakaipa, iyo inokonzera zvinhu zvayo zvinonyunguduka mumvura.

Properties

Sodium carboxymethyl cellulose ine akati wandei akasiyana zvimiro anoita kuti ive yakakosha muzvigadzirwa zvekudya. Iyo isiri-chepfu, isingagumbure, uye isiri-allergenic chinhu. Iyo zvakare yakanakisa thickener uye stabilizer, iyo inoita kuti ive yakakodzera kushandiswa mumasosi nemapfekero. CMC zvakare inoshanda emulsifier, iyo inobatsira kuchengetedza mafuta uye mvura-yakavakirwa zvinhu kubva pakupatsanura. Iyo inopesanawo nekupisa, asidi, uye alkali, iyo inoita kuti ive yakakodzera kushandiswa mune zvakasiyana-siyana zvezvokudya zvekudya.

Uses

Sodium carboxymethyl cellulose inoshandiswa mumhando dzakasiyana dzezvigadzirwa zvekudya, zvinosanganisira ice cream, masalad dressings, sosi, uye zvakabikwa. Inoshandiswawo mumishonga, cosmetics, uye detergents. Muzvigadzirwa zvechikafu, CMC inoshandiswa seyakakora, stabilizer, uye emulsifier. Inobatsira kuchengetedza zvigadzirwa kubva pakuparadzanisa uye inovandudza kuumbwa uye kuwirirana kwechigadzirwa. Mumishonga, CMC inoshandiswa sebhainda uye disintegrant. Muzvizoro, inoshandiswa seyakakora uye inodzikamisa. Mune detergents, inoshandiswa se dispersant uye emulsifier.

Safety

Sodium carboxymethyl cellulose inowanzo zivikanwa seyakachengeteka (GRAS) neUS Food and Drug Administration (FDA). Inotenderwawo kushandiswa muzvigadzirwa zvekudya muEuropean Union. CMC haina chepfu uye isiri-allergenic, uye yakashandiswa muzvigadzirwa zvekudya kweanopfuura makore makumi mashanu. Nekudaro, zvakakosha kuziva kuti CMC inogona kutora mvura, izvo zvinogona kuita kuti izvimbe uye ive viscous. Izvi zvinogona kukonzera kukachidzwa kana chigadzirwa chikasadyiwa nemazvo.
