Kev nyab xeeb ntawm HPMC hauv cov khoom noj ntxiv

1. Txheej txheem cej luam ntawm HPMC

HPMC (Hydroxypropyl Methylcellulose) yog cellulose derivative tau los ntawm kev hloov kho tshuaj. Nws tau txais los ntawm cov nroj tsuag ntuj cellulose los ntawm cov tshuaj tiv thaiv xws li methylation thiab hydroxypropylation. HPMC muaj dej solubility zoo, viscosity hloov, zaj duab xis-forming zog thiab stability, yog li nws tau dav siv nyob rau hauv ntau industries, tshwj xeeb tshaj yog nyob rau hauv cov zaub mov, tshuaj thiab tshuaj pleev ib ce, raws li ib tug thickener, stabilizer, emulsifier thiab gelling neeg sawv cev.

Hauv kev lag luam khoom noj khoom haus, HPMC feem ntau yog siv los ua cov thickener, gelling agent, humectant, emulsifier thiab stabilizer. Nws daim ntawv thov ntau yam hauv cov khoom noj muaj xws li: qhob cij, ncuav mog qab zib, biscuits, khoom qab zib, ice cream, condiments, dej haus thiab ib co zaub mov noj qab haus huv. Ib qho laj thawj tseem ceeb rau nws daim ntawv thov dav yog tias AnxinCel®HPMC muaj tshuaj lom neeg ruaj khov zoo, tsis yooj yim rau kev hnov ​​​​mob nrog lwm cov khoom xyaw, thiab yooj yim degraded nyob rau hauv cov xwm txheej tsim nyog.

2. Kev soj ntsuam kev nyab xeeb ntawm HPMC

HPMC tau raug lees paub thiab pom zoo los ntawm ntau lub teb chaws thiab thoob ntiaj teb cov koom haum saib xyuas kev nyab xeeb zaub mov raws li cov khoom noj ntxiv. Nws txoj kev nyab xeeb feem ntau yog ntsuas los ntawm cov hauv qab no:

Kev kawm txog toxicology

Raws li ib tug derivative ntawm cellulose, HPMC yog raws li cov nroj tsuag cellulose thiab muaj kuj tsis tshua muaj toxicity. Raws li ntau yam kev tshawb fawb toxicology, kev siv HPMC hauv cov zaub mov tsis qhia pom tseeb tias mob hnyav lossis mob toxicity. Feem ntau cov kev tshawb fawb tau pom tias HPMC muaj biocompatibility zoo thiab yuav tsis ua rau muaj kev phom sij rau tib neeg lub cev. Piv txwv li, cov txiaj ntsig ntawm qhov kev sim tshuaj lom ntawm qhov ncauj ntawm HPMC ntawm cov nas pom tau tias tsis muaj cov tshuaj lom tshuaj lom neeg pom tseeb tshwm sim ntawm cov koob tshuaj ntau (ntau tshaj li niaj hnub siv cov khoom noj ntxiv).

Kev Noj Qab Haus Huv thiab ADIs (Acceptable Daily Intake)

Raws li kev soj ntsuam ntawm cov kws paub txog kev nyab xeeb ntawm cov khoom noj, qhov kev siv tau txhua hnub (ADI) ntawm HPMC yuav tsis ua mob rau tib neeg kev noj qab haus huv nyob rau hauv ntau yam kev siv. Pawg Kws Tshaj Lij Thoob Ntiaj Teb ntawm Cov Khoom Noj Ntxiv (JECFA) thiab US Food and Drug Administration (FDA) thiab lwm lub koom haum tau lees paub txog kev nyab xeeb ntawm HPMC raws li cov khoom noj ntxiv thiab teeb tsa kev siv tsim nyog rau nws. Hauv nws daim ntawv tshaj tawm kev ntsuam xyuas, JECFA tau taw qhia tias HPMC tsis tau pom muaj cov teebmeem tshuaj lom neeg pom tseeb, thiab nws txoj kev siv hauv cov zaub mov feem ntau nyob deb ntawm tus nqi ADI, yog li cov neeg siv khoom tsis tas yuav txhawj xeeb txog nws cov kev pheej hmoo kev noj qab haus huv.

Kev tsis haum tshuaj thiab kev phiv tshuaj

Raws li cov khoom siv ntuj tsim, HPMC muaj qhov tshwm sim tsawg ntawm kev tsis haum tshuaj. Cov neeg feem coob tsis muaj kev fab tshuaj rau HPMC. Txawm li cas los xij, qee cov neeg rhiab heev yuav muaj cov tsos mob ua xua me xws li pob khaus thiab ua tsis taus pa thaum noj zaub mov uas muaj HPMC. Cov tshuaj tiv thaiv zoo li no feem ntau tsis tshua muaj. Yog tias muaj kev tsis xis nyob, nws raug nquahu kom tsis txhob noj cov zaub mov uas muaj HPMC thiab nrhiav kev qhia los ntawm kws kho mob.

Kev noj qab haus huv ntev thiab plab hnyuv

Raws li cov khoom siv molecular siab, AnxinCel®HPMC yog qhov nyuaj rau kev nqus los ntawm tib neeg lub cev, tab sis nws tuaj yeem ua lub luag haujlwm xws li cov khoom noj fiber ntau hauv cov hnyuv thiab txhawb cov hnyuv peristalsis. Yog li ntawd, kev noj HPMC nruab nrab yuav muaj txiaj ntsig zoo rau txoj hnyuv. Piv txwv li, qee qhov kev tshawb fawb tau pom tias HPMC muaj qee yam peev xwm los txhim kho plab hnyuv peristalsis thiab txo cov cem quav. Txawm li cas los xij, kev noj HPMC ntau dhau tuaj yeem ua rau mob plab hnyuv, mob plab, raws plab thiab lwm yam tsos mob, yog li yuav tsum ua raws li txoj cai tswjfwm.

3. Kev pom zoo ntawm HPMC nyob rau ntau lub tebchaws

Tuam Tshoj

Hauv Suav teb, HPMC tau teev npe raws li cov khoom noj tau tso cai, feem ntau yog siv hauv cov khoom qab zib, khoom qab zib, dej haus, khoom noj khoom haus, thiab lwm yam. Raws li "Standard for the Use of Food Additives" (GB 2760-2014), HPMC tau pom zoo siv. nyob rau hauv cov khoom noj tshwj xeeb thiab muaj kev txwv nruj heev.

European Union

Hauv European Union, HPMC kuj tau lees paub tias yog cov khoom noj muaj kev nyab xeeb, suav nrog E464. Raws li tsab ntawv ceeb toom kev soj ntsuam ntawm European Food Safety Authority (EFSA), HPMC muaj kev nyab xeeb raws li cov kev cai ntawm kev siv thiab tsis muaj kev cuam tshuam rau tib neeg kev noj qab haus huv.

Tebchaws Meskas

Teb Chaws Asmeskas FDA teev HPMC ua "Kev Pom Zoo Raws Li Kev Nyab Xeeb" (GRAS) thiab tso cai rau nws siv hauv cov khoom noj. FDA tsis tau teeb tsa cov kev txwv nruj rau kev siv HPMC, thiab feem ntau ntsuas nws txoj kev nyab xeeb raws li cov ntaub ntawv tshawb fawb hauv kev siv tiag tiag.

Raws li cov khoom noj additive,HPMC tau txais kev pom zoo nyob rau hauv ntau lub teb chaws thiab cheeb tsam thoob ntiaj teb thiab pom tau tias muaj kev nyab xeeb nyob rau hauv qhov kev siv ntau yam. Nws txoj kev nyab xeeb tau raug txheeb xyuas los ntawm ntau yam kev tshawb fawb toxicological thiab kev kho mob, thiab nws tsis ua rau muaj kev phom sij loj rau tib neeg kev noj qab haus huv. Txawm li cas los xij, zoo li txhua yam khoom noj ntxiv, kev noj HPMC yuav tsum ua raws li txoj cai ntawm kev siv kom tsim nyog thiab tsis txhob noj ntau dhau. Cov neeg uas muaj kev fab tshuaj yuav tsum tau ceev faj thaum noj cov zaub mov uas muaj HPMC kom txo tau qhov tshwm sim tsis zoo.

HPMC yog cov khoom siv dav siv thiab muaj kev nyab xeeb hauv kev lag luam zaub mov, ua rau muaj kev pheej hmoo me me rau pej xeem kev noj qab haus huv. Nrog rau kev nce qib ntawm kev tshawb fawb thiab thev naus laus zis, kev tshawb fawb thiab kev saib xyuas ntawm AnxinCel®HPMC yuav nruj dua yav tom ntej kom ntseeg tau tias nws muaj kev nyab xeeb.
