Hydroxyethylcellulose (HEC) inonyanya kuzivikanwa seyakakora uye gelling agent mumaindasitiri akasiyana siyana, kusanganisira zvekuzora, zvemishonga, uye kunyangwe mune zvimwe zvigadzirwa zvekudya. Nekudaro, kushandiswa kwayo kwekutanga hakusi sechikafu chekuwedzera, uye haiwanzo kudyiwa zvakananga nevanhu muhuwandu hwakakosha. Izvo zvakati, zvinoonekwa zvakachengeteka kuti zvishandiswe muzvigadzirwa zvechikafu nemitumbi inodzora kana ichishandiswa mukati memimwe miganhu. Heino tarisiro yakazara yehydroxyethylcellulose uye yayo yekuchengetedza chimiro:
Chii chinonzi Hydroxyethylcellulose (HEC)?
Hydroxyethylcellulose isiri-ionic, mvura-inonyungudika polima inotorwa kubva muselulosi, chinhu chakasikwa chinowanikwa mumiti. Inogadzirwa nekurapa cellulose ne sodium hydroxide uye ethylene oxide. Mushonga unoguma une zvakasiyana-siyana zvekushandisa nekuda kwekukwanisa kwayo kukora uye kudzikamisa mhinduro, kugadzira gel akajeka kana viscous zvinwiwa.
Kushandiswa kweHEC
Cosmetics: HEC inowanzowanikwa muzvigadzirwa zvekuzora zvakadai semafuta ekuzora, makirimu, shampoos, uye gels. Inobatsira kupa maitiro uye kuwirirana kune zvigadzirwa izvi, kuvandudza kushanda kwavo uye kunzwa paganda kana bvudzi.
Pharmaceuticals: Mukugadzirwa kwemishonga, HEC inoshandiswa seyakakora, stabilizer, uye emulsifier mumishonga yakasiyana-siyana yemusoro uye yemuromo.
Indasitiri yeChikafu: Kunyange isingawande sezvizora nemishonga, HEC inogara ichishandiswa muindasitiri yechikafu seyakakora mumiriri, stabilizer, kana emulsifier muzvigadzirwa zvakaita sososi, madhirezi, uye dzimwe nzira dzemukaka.
Kuchengetedzwa kweHEC muChikafu Zvigadzirwa
Kuchengeteka kwehydroxyethylcellulose muzvigadzirwa zvechikafu kunoongororwa nemasangano anodzora akadai seUS Food and Drug Administration (FDA), European Food Safety Authority (EFSA), uye masangano akafanana pasi rese. Aya masangano anowanzo ongorora kuchengetedzeka kwezvinowedzera zvekudya zvichibva paumbowo hwesainzi maererano nekugona kwavo huturu, allergenicity, uye zvimwe zvinhu.
1. Regulatory Mvumo: HEC inowanzo zivikanwa seyakachengeteka (GRAS) yekushandisa muzvigadzirwa zvekudya kana ichishandiswa maererano nemaitiro akanaka ekugadzira uye mukati memiganhu yakatarwa. Yakapiwa nhamba yeE (E1525) neEuropean Union, ichiratidza kubvumirwa kwayo sechikafu chekuwedzera.
2. Zvidzidzo Zvekuchengetedza: Kunyangwe paine tsvakurudzo shoma yakanangana nekuchengetedzeka kweHEC muzvigadzirwa zvekudya, zvidzidzo pamusoro pezvinobva muselulosi zvine hukama zvinoratidza njodzi yakaderera yehuturu kana ichidyiwa muhuwandu hwakajairika. Cellulose derivatives haina metabolized nemuviri wemunhu uye inoburitswa isina kuchinjika, zvichiita kuti ive yakachengeteka kudyiwa.
3. Inogamuchirwa Zuva Nezuva Intake (ADI): Masangano ekugadzirisa anogadza kugamuchirwa kwezuva nezuva (ADI) yezvokudya zvinowedzera, kusanganisira HEC. Izvi zvinomiririra huwandu hwekuwedzera hunogona kudyiwa zuva nezuva kwehupenyu hwese pasina njodzi yehutano. Iyo ADI yeHEC yakavakirwa pane toxicological zvidzidzo uye yakaiswa pamwero unoonekwa seusingagone kukuvadza.
hydroxyethylcellulose inoonekwa seyakachengeteka kuti ishandiswe muzvigadzirwa zvechikafu kana ichishandiswa mukati memitemo yemitemo. Kunyangwe isiri iyo yakajairika yekuwedzera chikafu uye inonyanya kushandiswa mune zvekuzora nemishonga, kuchengetedzeka kwayo kwakaongororwa nemasangano anodzora, uye yakatenderwa kuti ishandiswe mukushandiswa kwechikafu. Sezvinoita chero chekuwedzera chikafu, zvakakosha kushandisa HEC zvinoenderana neyakakurudzirwa mazinga ekushandisa uye kutevedzera yakanaka yekugadzira maitiro kuti uve nechokwadi chekuchengetedzwa kwechigadzirwa.
