Kev ntim khoom noj yog ib txoj haujlwm tseem ceeb hauv kev tsim khoom noj thiab kev ncig, tab sis thaum nqa cov txiaj ntsig thiab kev yooj yim rau tib neeg, kuj tseem muaj teeb meem ua paug ib puag ncig los ntawm kev ntim khoom pov tseg.Yog li ntawd, nyob rau hauv xyoo tas los no, kev npaj thiab kev siv cov khoom ntim khoom noj tau ua nyob rau hauv tsev thiab txawv teb chaws.Raws li kev tshawb fawb, cov khoom ntim khoom noj muaj cov yam ntxwv ntawm kev tiv thaiv ib puag ncig ntsuab, kev nyab xeeb thiab biodegradability.Nws tuaj yeem ua kom cov zaub mov zoo los ntawm kev ua haujlwm ntawm cov pa oxygen, kev tiv thaiv dej noo thiab solute migration, thiaj li txuas ntxiv lub txee lub neej ntawm cov zaub mov.Lub edible ntim zaj duab xis yog tsim los ntawm cov khoom siv roj ntsha macromolecular, uas muaj qee yam kev siv zog thiab cov roj tsawg, oxygen thiab dej permeability, thiaj li tiv thaiv kom tsis txhob muaj cov kua txiv hmab txiv ntoo lossis roj, thiab cov seasoning yuav ntub thiab mildewed Ntxiv rau. , nws muaj qee yam dej solubility thiab yooj yim noj.Nrog rau txoj kev loj hlob sai ntawm kuv lub teb chaws txoj kev lag luam ua zaub mov yooj yim, daim ntawv thov ntawm cov khoom ntim khoom noj khoom haus hauv cov khoom noj yuav maj mam nce ntxiv rau yav tom ntej.
01. Sodium carboxymethyl cellulose
Sodium carboxymethyl cellulose (CMC-Na) yog carboxymethylated derivative ntawm cellulose thiab yog qhov tseem ceeb tshaj plaws ionic cellulose pos hniav.Sodium carboxymethyl cellulose feem ntau yog anionic polymer compound npaj los ntawm reacting natural cellulose nrog caustic alkali thiab monochloroacetic acid, nrog ib tug molecular hnyav li ntawm ntau txhiab mus rau lab.CMC-Na yog dawb fibrous los yog granular hmoov, tsis muaj ntxhiab, tasteless, hygroscopic, yooj yim rau disperse nyob rau hauv dej los tsim ib tug pob tshab colloidal tov.
Sodium carboxymethyl cellulose yog ib hom thickener.Vim nws cov khoom siv tau zoo, nws tau siv dav hauv kev lag luam khoom noj khoom haus, thiab nws kuj tau txhawb kev loj hlob sai thiab noj qab nyob zoo ntawm kev lag luam khoom noj rau qee yam.Piv txwv li, vim nws cov nyhuv thickening thiab emulsifying, nws tuaj yeem siv los tswj cov dej qab zib yogurt thiab ua kom cov viscosity ntawm yogurt system;vim nws muaj qee yam hydrophilicity thiab rehydration zog, nws tuaj yeem siv los txhim kho kev noj cov nplej zom xws li qhob cij thiab steamed qhob cij.zoo, ncua lub txee lub neej ntawm cov khoom pasta, thiab txhim kho saj;vim nws muaj cov nyhuv gel, nws yog qhov tsim nyog rau kev tsim cov gel zoo dua hauv cov zaub mov, yog li nws tuaj yeem siv los ua jelly thiab jam;Nws tseem tuaj yeem siv los ua cov yeeb yaj kiab uas siv tau Cov khoom siv sib xyaw nrog lwm cov thickeners thiab siv rau saum npoo ntawm qee cov khoom noj, uas tuaj yeem khaws cov zaub mov tshiab kom zoo tshaj plaws, thiab vim tias nws yog cov khoom siv tau, nws yuav tsis ua rau muaj kev phom sij. cuam tshuam rau tib neeg kev noj qab haus huv.Yog li ntawd, zaub mov-qib CMC-Na, raws li cov khoom noj khoom haus zoo tshaj plaws, yog siv dav hauv kev tsim khoom noj hauv kev lag luam khoom noj.
02. Sodium carboxymethylcellulose edible zaj duab xis
Carboxymethyl cellulose yog ib qho cellulose ether uas tuaj yeem tsim cov yeeb yaj kiab zoo hauv daim ntawv thermal gels, yog li nws tau siv dav hauv kev lag luam tshuaj thiab zaub mov.Carboxymethyl cellulose zaj duab xis yog cov pa oxygen, carbon dioxide thiab lipid barrier, tab sis nws muaj kev tiv thaiv tsis zoo rau dej vapor kis.Cov yeeb yaj kiab uas siv tau tuaj yeem txhim kho los ntawm kev ntxiv cov khoom siv hydrophobic, xws li lipids, rau cov tshuaj ua yeeb yaj kiab yog li ntawd, nws tseem hu ua lipid derivative muaj peev xwm.
1. CMC-lotus cag hmoov txhuv nplej siab-tshuaj yej tsob ntoo roj edible zaj duab xis tuaj yeem ua tau raws li cov kev xav tau ntawm kev ntsuab, kev nyab xeeb thiab tsis muaj kuab paug, uas tsis tsuas yog ua kom cov zaub mov zoo xwb tab sis kuj tsis txo cov nyhuv ntim.Nws yuav tsum tau tsim thiab siv nyob rau hauv instant noodles, instant kas fes, instant oatmeal thiab soybean mis hmoov rau yav tom ntej.Lub hnab ntim sab hauv hloov cov yas zaj duab xis tsoos.
2. Siv carboxymethyl cellulose ua zaj duab xis-tsim cov khoom siv hauv paus, glycerin li plasticizer, thiab ntxiv cov hmoov txhuv nplej siab los ua cov khoom siv los npaj cov khoom noj khoom haus uas muaj cov khoom sib xyaw ua ke, nws yog qhov tsim nyog rau kev ntim cov kua txiv hmab txiv ntoo thiab cov hmoov ntim rau hauv 30 hnub thiab roj rau lub sijhawm ntev. wrapping zaj duab xis.
3. Siv txiv qaub tev hmoov, glycerin, thiab sodium carboxymethylcellulose ua zaj duab xis-forming raw khoom rau txiv qaub tev edible films
4. Siv sodium carboxymethyl cellulose aqueous tov raws li tus neeg nqa khoom thiab cov khoom noj-qib nobiletin ua cov khoom siv raw, cov khoom sib xyaw ntawm nobiletin-sodium carboxymethyl cellulose tau npaj los txuas ntxiv lub txee lub neej ntawm cucumbers.
