Kev Nyab Xeeb ntawm HPMC hauv cov khoom noj khoom haus ntxiv

1. Txheej txheem cej luam ntawm HPMC

HPMC (Hydroxypropyl Methylcellulose) yog ib qho cellulose derivative tau los ntawm kev hloov kho tshuaj lom neeg. Nws tau txais los ntawm cov nroj tsuag cellulose ntuj los ntawm cov tshuaj tiv thaiv xws li methylation thiab hydroxypropylation. HPMC muaj cov dej solubility zoo, viscosity hloov kho, zaj duab xis-tsim cov khoom thiab ruaj khov, yog li nws tau siv dav hauv ntau yam lag luam, tshwj xeeb tshaj yog nyob rau hauv cov teb ntawm cov khoom noj, tshuaj thiab tshuaj pleev ib ce, ua ib tug thickener, stabilizer, emulsifier thiab gelling tus neeg sawv cev.

Hauv kev lag luam khoom noj, HPMC feem ntau siv ua cov khoom ua kom tuab, cov khoom ua kom gelling, cov khoom ua kom noo noo, cov khoom ua kom emulsifier thiab cov khoom ua kom ruaj khov. Nws siv tau rau hauv cov khoom noj xws li: mov ci, ncuav mog qab zib, ncuav qab zib, khoom qab zib, ice cream, cov khoom qab zib, dej haus thiab qee yam khoom noj khoom haus zoo. Ib qho laj thawj tseem ceeb rau nws txoj kev siv dav yog vim AnxinCel®HPMC muaj kev ruaj khov tshuaj zoo, tsis yooj yim rau kev cuam tshuam nrog lwm cov khoom xyaw, thiab yooj yim lwj hauv qab cov xwm txheej tsim nyog.

2. Kev ntsuam xyuas kev nyab xeeb ntawm HPMC

HPMC tau lees paub thiab pom zoo los ntawm ntau lub koom haum tswj kev nyab xeeb zaub mov hauv tebchaws thiab thoob ntiaj teb ua ib qho khoom noj khoom haus ntxiv. Nws txoj kev nyab xeeb feem ntau raug soj ntsuam los ntawm cov hauv qab no:

Kev tshawb fawb txog tshuaj lom

Raws li ib qho cellulose derivative, HPMC yog raws li cov nroj tsuag cellulose thiab muaj qhov tsis tshua muaj tshuaj lom. Raws li ntau txoj kev tshawb fawb txog toxicology, kev siv HPMC hauv zaub mov tsis qhia txog kev lom neeg mob hnyav lossis mob ntev. Feem ntau cov kev tshawb fawb tau qhia tias HPMC muaj kev sib raug zoo biocompatibility zoo thiab yuav tsis ua rau muaj kev phiv tshuaj rau tib neeg lub cev. Piv txwv li, cov txiaj ntsig ntawm kev sim tshuaj lom neeg ntawm qhov ncauj ntawm HPMC ntawm nas tau qhia tias tsis muaj kev phiv tshuaj lom tshwm sim ntawm cov koob tshuaj ntau (dhau li kev siv cov khoom noj txhua hnub).

Kev Noj Haus thiab ADIs (Kev Noj Haus Txhua Hnub Uas Txais Tau)

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

Kev tsis haum tshuaj thiab kev tsis haum tshuaj

Ua ib yam khoom ntuj, HPMC muaj qhov tshwm sim tsawg ntawm kev ua xua. Cov neeg feem coob tsis muaj kev ua xua rau HPMC. Txawm li cas los xij, qee tus neeg rhiab heev yuav muaj cov tsos mob me me xws li pob khaus thiab ua pa luv luv thaum noj cov khoom noj uas muaj HPMC. Cov kev ua xua no feem ntau tsis tshua muaj. Yog tias tsis xis nyob, nws raug pom zoo kom tsum tsis txhob noj cov khoom noj uas muaj HPMC thiab nrhiav kev qhia ntawm tus kws kho mob.

Kev noj mus sij hawm ntev thiab kev noj qab haus huv ntawm txoj hnyuv

Ua ib qho tshuaj muaj molecular siab, AnxinCel®HPMC nyuaj rau tib neeg lub cev nqus tau, tab sis nws tuaj yeem ua lub luag haujlwm ua cov khoom noj muaj fiber ntau hauv txoj hnyuv thiab txhawb nqa txoj hnyuv peristalsis. Yog li ntawd, kev noj HPMC me ntsis yuav muaj qee qhov zoo rau kev noj qab haus huv ntawm txoj hnyuv. Piv txwv li, qee qhov kev tshawb fawb tau qhia tias HPMC muaj qee qhov peev xwm hauv kev txhim kho txoj hnyuv peristalsis thiab txo qhov mob cem quav. Txawm li cas los xij, kev noj HPMC ntau dhau yuav ua rau mob plab hnyuv, mob plab, raws plab thiab lwm yam tsos mob, yog li yuav tsum ua raws li txoj cai ntawm kev noj qab haus huv.

3. Kev pom zoo ntawm HPMC hauv ntau lub tebchaws

Tuam Tshoj

Hauv Suav teb, HPMC tau teev tseg ua cov khoom noj khoom haus uas raug tso cai, feem ntau yog siv rau hauv cov khoom qab zib, cov khoom qab zib, dej haus, cov khoom ua los ntawm pasta, thiab lwm yam. Raws li "Tus Qauv rau Kev Siv Cov Khoom Noj Khoom Haus" (GB 2760-2014), HPMC tau pom zoo rau kev siv rau hauv cov khoom noj tshwj xeeb thiab muaj kev txwv tsis pub siv.

European Union

Raws li daim ntawv ntsuam xyuas ntawm European Food Safety Authority (EFSA), HPMC muaj kev nyab xeeb raws li cov xwm txheej tshwj xeeb ntawm kev siv thiab tsis qhia txog kev phiv rau tib neeg kev noj qab haus huv.

Tebchaws Meskas

Lub Koom Haum FDA hauv Tebchaws Meskas teev cov HPMC ua ib yam khoom "Generally Recognized As Safe" (GRAS) thiab tso cai rau nws siv rau hauv cov khoom noj. FDA tsis teem 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.

Ua ib qho khoom noj khoom haus ntxiv,HPMC tau txais kev pom zoo hauv ntau lub tebchaws thiab thaj chaw thoob plaws ntiaj teb thiab suav tias muaj kev nyab xeeb hauv qhov ntau thiab tsawg siv. Nws txoj kev nyab xeeb tau raug txheeb xyuas los ntawm ntau txoj kev tshawb fawb txog tshuaj lom thiab kev coj ua hauv kev kho mob, thiab nws tsis ua rau muaj kev phom sij rau tib neeg kev noj qab haus huv.
