Puas yog HPMC noj tau zoo?

Hydroxypropyl Methylcellulose (HPMC)yog ib qho cellulose ether nonionic tau los ntawm kev hloov kho tshuaj ntawm cov nroj tsuag cellulose. Nws yog dav siv hauv zaub mov, tshuaj, tshuaj pleev ib ce, cov ntaub ntawv tsim kho thiab lwm yam teb.

1. Qhov chaw thiab cov yam ntxwv ntawm HPMC

HPMC yog cov tshuaj polymer uas yaj tau hauv dej uas ua los ntawm kev sib xyaw ua ke ntawm methylation thiab hydroxypropylation raws li paj rwb ntuj, ntoo pulp thiab lwm yam nroj tsuag fibers. Nws tsis muaj cov khoom xyaw ntawm tsiaj thiab tsis cuam tshuam nrog kev hloov pauv caj ces. Yog li ntawd, nws yog siv los ua cov khoom noj ntxiv rau hauv cov zaub mov thiab tsim nyog rau ntau yam kev noj haus xws li cov neeg tsis noj nqaij, halal, thiab cov zaub mov Yudais.

Cov haujlwm tseem ceeb ntawm HPMC yog thickening, zaj duab xis tsim, ruaj khov emulsification, tswj kev tso tawm, thiab lwm yam. Vim nws qhov kev ruaj khov thermal zoo, cov calories tsawg, thiab kev zom zaub mov thiab kev nqus los ntawm tib neeg lub cev, nws tau dhau los ua cov khoom siv ua haujlwm feem ntau hauv kev lag luam zaub mov.

2. Daim ntawv pov thawj thiab cov cai tswjfwm kev nyab xeeb zaub mov thoob ntiaj teb tso cai

HPMC tau raug lees paub tias yog ib qho khoom noj khoom haus thiab noj tau los ntawm cov koom haum tswj hwm zaub mov thiab tshuaj hauv ntau lub tebchaws thiab thaj chaw, raws li hauv qab no:

Pawg Neeg Saib Xyuas Kev Sib Koom Tes ntawm Cov Khoom Noj Khoom Haus Ntxiv (JECFA) ntawm Lub Koom Haum Khoom Noj thiab Kev Ua Liaj Ua Teb / Lub Koom Haum Kev Noj Qab Haus Huv Ntiaj Teb (FAO / WHO) ntawm United Nations

teev HPMC ua cov khoom ua kom tuab, emulsifier thiab stabilizer uas siv tau rau hauv cov zaub mov, thiab tsis muaj kev txwv noj txhua hnub (ADI tsis tau teev tseg), qhia tias qhov tshuaj lom tsawg heev.

Lub Koom Haum Saib Xyuas Khoom Noj thiab Tshuaj ntawm Tebchaws Meskas (FDA)

faib HPMC ua GRAS (Feem ntau lees paub tias muaj kev nyab xeeb), tso cai rau nws siv rau hauv zaub mov, tshuaj, khoom noj qab haus huv thiab lwm yam teb.

European Union (EU)

Raws li European Food Additives Regulation No. E464, HPMC tau pom zoo rau kev siv ua khoom noj khoom haus ntxiv.

Tuam Tshoj Lub Tebchaws Kev Nyab Xeeb Khoom Noj Khoom Haus Txheem (GB2760)

Qhia meej meej txog HPMC ua cov khoom noj khoom haus ntxiv, uas siv tau rau hauv cov plhaub capsule, cov khoom noj uas muaj roj tsawg, cov khoom noj pasta, cov khoom noj mis nyuj, cov khoom noj khov, thiab lwm yam, thiab qhia meej txog qhov ntau thiab tsawg ntawm kev siv.

3. Kev tshawb fawb txog tshuaj lom thiab kev tshuaj xyuas kev nyab xeeb ntawm cov tsiaj txhu

Kev nyab xeeb ntawm HPMC tau lees paub los ntawm ntau yam kev sim tsiaj thiab kev kuaj mob hauv tsev kho mob:

Cov txiaj ntsig ntawm kev ntsuam xyuas tshuaj lom qhia tau tias muaj tshuaj lom tsawg heev: Kev tshawb fawb txog tshuaj lom neeg mob hnyav, subacute thiab mob ntev tau qhia tias tsis muaj kev phiv tshuaj pom tseeb txawm tias thaum noj ntau ntawm HPMC.

Tsis zom thiab nqus los ntawm tib neeg lub cev: HPMC yuav tsis raug rhuav tshem thiab nqus los ntawm cov enzymes gastrointestinal, yog li nws tsis koom nrog kev ua haujlwm ntawm lub zog thiab yuav tsis ua rau cov ntshav qab zib nce siab. Nws yog qhov tsim nyog rau cov neeg mob ntshav qab zib lossis cov neeg uas xav kom poob phaus.

Tsis muaj carcinogenicity, tsis muaj teratogenicity, tsis muaj genotoxicity: Kev noj mus sij hawm ntev tsis tau pom muaj pov thawj ntawm carcinogenicity lossis genotoxicity.

4. Cov piv txwv siv rau hauv cov khoom noj

HPMC siv dav hauv cov khoom noj, thiab cov kev siv feem ntau suav nrog:

Cov tshuaj ntsiav zaub: HPMC yog cov khoom siv zoo tshaj plaws rau kev ua cov tshuaj ntsiav cog, hloov cov gelatin ib txwm muaj, tsim nyog rau cov neeg tsis noj nqaij.

Cov khoom noj uas muaj roj tsawg/hloov pluas noj: siv los ua kom saj ntawm cov rog, ua rau tuab thiab txaus siab, feem ntau pom muaj nyob rau hauv cov dej khov nab kuab uas muaj roj tsawg, cov khoom noj muaj protein, cov mis nyuj qab zib, thiab lwm yam.

Cov noodles: Ntxiv HPMC rau cov noodles thiab qhob cij tuaj yeem txhim kho elasticity, tiv thaiv kev laus, saj thiab khaws cia noo noo.

Cov khoom noj khov sai: Txhim kho qhov ruaj khov ntawm cov khoom noj thaum lub sijhawm khov thiab yaj.

Cov khoom noj mis nyuj thiab dej haus: Siv rau emulsification, ncua thiab stabilization ntawm emulsions, xws li lactic acid bacteria dej haus, protein dej haus, thiab lwm yam.

5. Puas muaj tej yam txaus ntshai lossis teeb meem ua xua?

Feem ntau, HPMC muaj kev ua xua tsawg heev vim nws yog cov khoom xyaw uas muaj cov nroj tsuag ntshiab uas tsis muaj protein thiab yuav tsis ua rau muaj kev ua xua. Hauv qee kis tsis tshua muaj, yog tias ib tus neeg muaj kev rhiab heev rau cov khoom ntxiv cellulose, nws yuav ua rau mob plab hnyuv me ntsis (xws li o thiab mob plab ntau ntxiv), tab sis qhov no feem ntau tuaj yeem txo tau los ntawm kev txo cov tshuaj lossis tsum tsis txhob noj.

6. HPMC muaj kev nyab xeeb thiab noj tau, nrog rau kev thov dav dav

Hydroxypropyl methylcellulose (HPMC), ua ib qho khoom noj khoom haus ua haujlwm nrog keeb kwm ntuj thiab kev txheeb xyuas kev nyab xeeb, tau lees paub dav dav tias muaj kev nyab xeeb rau kev noj thoob ntiaj teb thiab hauv tebchaws. Nws muaj qhov zoo ntawm kev tsis muaj tshuaj lom, tsis ua rau ua xua, tsis nqus tau, thiab muaj ntau yam haujlwm, thiab tau dhau los ua ib feem tseem ceeb ntawm kev lag luam zaub mov.
