Vim li cas cov khoom noj thiaj muaj hydroxypropyl methylcellulose?

Hydroxypropyl methylcellulose (HPMC)yog ib qho cellulose ether uas tsis yog ionic ua los ntawm cov nroj tsuag cellulose ntuj los ntawm kev hloov kho tshuaj lom neeg. Vim nws cov khoom siv lub cev thiab tshuaj lom neeg zoo heev, kev nyab xeeb thiab kev ua haujlwm zoo, nws yog siv dav hauv kev lag luam zaub mov ua cov khoom siv tuab, emulsifier, stabilizer, suspending agent, film-forming agent thiab dietary fiber additive.

1. Kev siv HPMC ntau hauv zaub mov

1.1. Cov khoom ua kom tuab thiab cov khoom ruaj khov

HPMC muaj cov dej solubility zoo thiab tuaj yeem tsim cov kua viscosity siab. Yog li ntawd, nws yog siv los ua cov khoom siv tuab hauv cov khoom noj xws li kua zaub, kua ntses, cov khoom noj mis nyuj, jams, puddings, thiab lwm yam. Nws tuaj yeem txhim kho qhov saj ntawm cov khoom, txhim kho cov qauv, thiab ua rau cov khoom noj ntom thiab du. Tib lub sijhawm, HPMC kuj tseem tuaj yeem tiv thaiv kev sib cais ntawm cov kua, yog li cov khoom tiav lawm tseem zoo ib yam thiab ruaj khov thaum khaws cia thiab thauj mus los.

1.2. Cov tshuaj emulsifiers thiab cov tshuaj uas ua rau cov khoom ntub dej

Hauv qee cov khoom noj uas muaj roj lossis cov khoom tawg uas raug tshem tawm, xws li cov kua zaub xas lav, dej qab zib, thiab dej haus protein zaub, HPMC tuaj yeem siv los ua emulsifier los pab dej thiab roj sib tov ua ib qho emulsion ruaj khov, thiab ua tus neeg sawv cev ncua kom tiv thaiv cov khoom tawg, ua rau cov khoom zoo li sib xws thiab zoo nkauj dua.

1.3. Cov neeg sawv cev tsim zaj duab xis thiab cov ntaub ntawv txheej

HPMC muaj cov yam ntxwv zoo heev rau kev tsim cov zaj duab xis thiab kev noj tau zoo, thiab tuaj yeem tsim cov zaj duab xis pob tshab, tsis muaj ntxhiab rau ntawm qhov chaw ntawm cov khoom noj kom tiv thaiv cov dej noo, roj, thiab oxidation. Piv txwv li, hauv cov khoom qab zib, txiv ntoo, khoom ci, lossis cov khoom noj khov, zaj duab xis HPMC tuaj yeem ntev lub txee lub neej thiab txhim kho qhov tsos thiab saj.

1.4. Cov khoom noj uas muaj fiber ntau

HPMC, ua ib qho tshuaj polymer uas tsis zom tau, tib neeg lub cev tsis tuaj yeem nqus tau. Yog li ntawd, nws tuaj yeem ntxiv rau hauv cov khoom noj ua cov fiber uas yaj tau los pab tswj kev noj qab haus huv ntawm txoj hnyuv, ncua kev nqus cov piam thaj, thiab pab tswj cov ntshav qab zib, uas muaj txiaj ntsig zoo rau cov neeg mob ntshav qab zib thiab cov neeg uas xav kom poob phaus.

1.5. Cov khoom siv thermal gel siv rau cov khoom noj uas muaj roj tsawg

HPMC tuaj yeem ua ib lub gel thaum raug cua sov. Cov yam ntxwv tshwj xeeb no siv dav hauv cov khoom noj uas tsis muaj roj ntau. Nws tuaj yeem ua rau cov roj saj zoo li cov rog hauv cov mis tsis muaj roj lossis cov mis tsis muaj roj ntau, txhim kho cov saj thiab cov qauv ntawm cov khoom. Piv txwv li, hauv cov roj margarine, mayonnaise lossis ice cream uas tsis muaj roj ntau, HPMC hloov ib feem ntawm cov rog, yog li ntawd cov saj tsis raug cuam tshuam thaum txo cov calories.

2. Cov txiaj ntsig ntawm HPMC

2.1. Kev nyab xeeb siab

HPMC yog ib yam khoom ntuj tsim los thiab tau txais kev pom zoo los ua ib yam khoom noj khoom haus ntxiv los ntawm cov koom haum tswj kev nyab xeeb zaub mov hauv ntau lub tebchaws thiab thaj chaw, suav nrog US FDA, EU EFSA, thiab National Health Commission ntawm Tuam Tshoj. Nws tsis zom thiab nqus tau hauv lub cev, tsis muaj tshuaj lom thiab tsis muaj teeb meem, thiab yog ib yam khoom GRAS (Feem ntau lees paub tias muaj kev nyab xeeb).

2.2. Kev ruaj khov zoo thaum tshav kub

HPMC muaj kev ua haujlwm ruaj khov ntawm qhov kub siab thiab tsis yooj yim rau lwj. Nws yog qhov tsim nyog rau kev ci, khov sai thiab ua kom sov cov khoom noj uas npaj txhij noj. Cov gel tsim tom qab cua sov tuaj yeem tswj tau qhov kev ncaj ncees ntawm cov qauv khoom noj, thiab tshwj xeeb tshaj yog tsim rau cov khoom noj microwave.

2.3. Noj tsawg thiab muaj txiaj ntsig zoo

HPMC tuaj yeem ua kom pom qhov viscosity zoo, ncua kev kawm thiab emulsification txawm tias ntawm qhov ntxiv tsawg (0.1% -2.0%), ua kom zoo dua cov khoom noj khoom haus zoo.

2.4. Zoo dua saj thiab qauv

Nws cov yam ntxwv tshwj xeeb uas ua rau cov dej noo thiab saj du thiab nplaum tuaj yeem txhim kho cov qauv ntawm cov zaub mov, xws li ua rau cov khoom ci mos dua, cov khob cij nthuav dav dua, thiab cov kua ntses du dua.

2.5. Lub sijhawm khaws cia khoom noj ntev dua

Thaum siv los ua tus neeg sawv cev tsim zaj duab xis, HPMC tuaj yeem tsim ib txheej tiv thaiv rau ntawm qhov chaw ntawm cov khoom noj, thaiv kev nkag mus ntawm cov pa oxygen, dej noo thiab cov kab mob me me, qeeb qeeb ntawm cov khoom noj khoom haus puas tsuaj thiab ntev lub txee lub neej.

3. Cov hom ntawv thov HPMC ib txwm muaj

Khoom noj ci: txhim kho qhov fluffiness thiab dej tuav peev xwm ntawm qhob cij thiab ncuav mog qab zib, thiab ncua kev laus;

Cov khoom noj mis nyuj thiab mis nyuj cog: ua cov emulsifiers thiab thickeners, ua kom cov qauv ruaj khov;

Khoom noj khov: txhim kho kev ruaj khov ntawm cov qauv thiab tiv thaiv kom tsis txhob khov thiab qhuav dej;

Cov khoom noj yooj yim (xws li cov noodles tam sim ntawd, cov hnab kua zaub): tiv thaiv kev sib cais roj-dej thiab txhim kho kev yaj;

Khoom noj uas muaj roj tsawg/zaub mov tsis muaj nqaij: ua kom saj roj zoo thiab txhim kho saj;

Cov khoom qab zib thiab cov khoom txheej: muab qhov chaw ci ntsa iab, tiv taus dej noo thiab tiv taus tawg.

Qhov laj thawj yog vim li casHPMC siv dav hauv cov khoom noj vim nws cov khoom ua haujlwm zoo heevthiab kev nyab xeeb zoo. Nws tsis tsuas yog ua rau tuab, emulsify, ua zaj duab xis thiab ruaj khov ntau yam khoom noj, tab sis kuj txhim kho qhov tsos, saj thiab kev khaws cia ntawm cov khoom noj, thaum ua tau raws li qhov xav tau ntawm cov neeg siv khoom niaj hnub no rau cov khoom noj uas tsis muaj roj ntau, noj qab haus huv thiab zoo. Ua ib qho khoom noj khoom haus ntau yam thiab muaj kev nyab xeeb heev, HPMC tab tom ua lub luag haujlwm tseem ceeb hauv kev lag luam khoom noj niaj hnub no.
