Hydroxypropyl Methyl Cellulose E464

Hydroxypropyl Methylcellulose (HPMC) yog ib tug semi-synthetic polymer muab tau los ntawm cellulose.Nws yog feem ntau siv hauv kev lag luam khoom noj khoom haus raws li cov khoom noj ntxiv nrog tus lej E E464.

HPMC yog tsim los ntawm kev kho cellulose nrog kev sib xyaw ua ke ntawm alkali thiab etherification agents, uas ua rau muaj kev hloov pauv ntawm qee pawg hydroxyl ntawm cov cellulose molecule nrog hydroxypropyl thiab methyl pawg.Qib ntawm kev hloov pauv txiav txim siab cov khoom ntawm HPMC, xws li nws cov khoom solubility thiab gelation.

Hauv cov khoom noj, HPMC yog siv los ua cov thickener, emulsifier, thiab stabilizer, ntawm lwm yam haujlwm.Nws tuaj yeem siv los txhim kho kev ntxhib los mos ntawm cov khoom noj xws li kua ntses, hnav khaub ncaws, thiab cov khoom ci.HPMC kuj tseem siv los ua cov txheej txheem rau cov ntsiav tshuaj thiab tshuaj ntsiav hauv kev lag luam kws tshuaj, nrog rau kev tsim kho tus kheej thiab cov khoom siv tshuaj pleev ib ce.

HPMC feem ntau suav hais tias muaj kev nyab xeeb rau kev noj thiab tau pom zoo siv rau hauv cov zaub mov los ntawm ntau lub koom haum tswj hwm thoob ntiaj teb, suav nrog US Food and Drug Administration (FDA) thiab European Food Safety Authority (EFSA).Txawm li cas los xij, nrog rau tag nrho cov khoom noj khoom haus ntxiv, nws yog ib qho tseem ceeb uas yuav tsum siv HPMC raws li kev pom zoo qib thiab cov kev cai kom ntseeg tau tias nws muaj kev nyab xeeb.
