1.Application hauv cov khoom siv mis nyuj

(1) Kev tshawb fawb txog kev siv tshuaj acidic

Acidic mis nyuj haus muaj ib qho tshwj xeeb qaub thiab qab zib tsw, thiab muaj kev lag luam dav. Txawm li cas los xij, thaum lub sij hawm tsim khoom, casein nyiam sib sau ua ke thiab ua tsis ruaj khov nyob rau hauv acidic tej yam kev mob. Yog li ntawd, ntxiv polysaccharides feem ntau muab kev tiv thaiv ntawm casein, stabilizing lub kaw lus thaum ua kom lub saj zoo. Cov txheej txheem ntawm carboxymethyl cellulose sodium raws li polysaccharide stabilizing acidic mis nyuj haus tuaj yeem piav qhia raws li hauv qab no: thaum lub sijhawm hloov cov kua qaub, thaum pH tus nqi yog 5.2, CMC Na pib adsorb rau ntawm qhov chaw ntawm casein gel hais, thiab nws cov nyhuv zoo ib yam. rau qhov ntawd nyob rau hauv nruab nrab tej yam kev mob κ- Lub luag hauj lwm ntawm casein, lub electrostatic repulsion thiab steric hindrance ntawm lub adsorption txheej tuav ruaj khov muaj nyob ruaj khov ntawm casein micelles, thiab CMC Na muaj ib tug thickening nyhuv, uas yuav txo tau cov sedimentation tus nqi ntawm cov protein hais. Cov txiaj ntsig tau qhia tias ntawm qhov pH qis, yuav tsum muaj qee qhov concentration ntawm carboxymethyl cellulose sodium; Thaum lub concentration qis dua qhov no, lub kaw lus yuav poob stability. Ntawm pH qhov tseem ceeb ntawm 3.6 ~ 4.6, qis pH tshuab yuav tsum muaj ntau sodium carboxymethyl cellulose kom stabilize. fermented acidic mis nyuj haus yuav tsum tau ntau dua stabilizers piv rau acid regulating dej qab zib.

Thiab cov kua mis acidic uas muaj cov txiv hmab txiv ntoo granules yuav tsum tau ntxiv ib qho ntawm cov txiv hmab txiv ntoo granules rau cov mis nyuj haus, thiab cov stabilizers kuj tseem xav tau los txhim kho lub cev. Cov kev sim tau pom tias CMC Na yog lub ntsiab stabilizer rau cov kua qaub mis nyuj haus. Thaum CMC Na tso nyiaj rau {{0}}.4% thiab pectin yog 0.14% hauv cov khoom sib xyaw ua ke, kev ruaj ntseg ntawm lub kaw lus zoo dua.

Cov kws tshawb fawb kuj tau kawm txog kev siv carboxymethyl cellulose sodium hauv lycopene cov dej haus kom ruaj khov. Kev tshawb fawb tau pom tias thaum tus nqi ntawm CMC Na ntxiv yog ntau dua 0.4%, cov khoom muaj kev ruaj ntseg zoo, tab sis cov viscosity nce siab heev nyob rau lub sijhawm no, yog li nws tuaj yeem xaiv los siv ua ke nrog lwm yam. colloids.

Tom qab ua kom zoo dua cov txheej txheem ntawm kev siv CMC Na cov khoom cua txias, cov tshuaj siv tshuaj acid tswj cov kua mis ib txwm muaj viscosity ntau dua li cov khoom siv thermal thaum lub sijhawm txee lub neej, ua rau muaj kev ruaj ntseg zoo dua. Qhov no tseem muab lub hauv paus theoretical rau kev siv zoo dua ntawm carboxymethyl cellulose sodium hauv kev tsim cov kua qaub mis nyuj haus.

(2) Daim ntawv thov ntawm stirred yogurt

Lub denaturation thiab nag lossis daus ntawm cov mis nyuj protein nyob rau hauv acidic tej yam kev mob yeej ib txwm yog ib qho teeb meem tseem ceeb cuam tshuam rau txoj kev loj hlob ntawm yogurt. Vim nws cov khoom siv ntau yam, ntau qhov chaw, thiab tus nqi pheej yig, CMC Na feem ntau yog siv los ua kom ruaj khov.

Cov txiaj ntsig tau pom tias CMC Na tau cuam tshuam zoo heev los ntawm qhov ntsuas kub thiab pH tus nqi. Thaum tus nqi ntawm CMC Na ntxiv me me, nws tsis tuaj yeem ua rau lub xeev yogurt. Thaum nws cov ntsiab lus ntau dua {{0}}.4%, yogurt lub xeev txhim kho thiab cov kab ke ua kom ruaj khov; Ntxiv mus, CMC Na muaj cov nyhuv me me ntawm cov yogurt ntawm qhov concentration ntawm 0.05% ~ 0.1%, thaum nws cov nyhuv thickening tseem ceeb nyob rau hauv ntau qhov loj ntawm cov ntsiab lus (0.4% ~ 0.5%).

(3) Kev siv cov tshuaj pleev ib ce

Lotion yog ib qho system dispersion tsim los ntawm ib cov kua dispersed nyob rau hauv daim ntawv ntawm me me droplets nyob rau hauv lwm yam immiscible kua, uas yog ib tug unstable system. Ntawm ntau cov khoom noj gels, carboxymethyl cellulose sodium thiab xanthan cov pos hniav tau raug tshawb fawb ntau vim lawv cov khoom ua haujlwm tshwj xeeb. Cov txiaj ntsig tau qhia tias kev sib xyaw ntawm CMC Na thiab XG (xanthan gum) tuaj yeem ua rau lub cev ruaj khov. Ntawm ib qho kev sib xyaw ua ke (CMC Na: XG yog 1 ∶ 1, 3 ∶ 1), tag nrho cov nyiaj ntxiv yog 0.4% ntawm tag nrho cov tshuaj pleev ib ce, thiab cov txheej txheej ruaj khov ntawm cov tshuaj pleev ib ce yuav nce ntxiv. Qhov tshwm sim txheej txheej tsis pom tseeb thaum lub emulsion khaws cia hauv chav sov li 2 lub lis piam.

Daim ntawv thov hauv kev tsim cov khob cij thiab Mantou

 

2.Carboxymethyl cellulose sodium muaj qee yam hydrophilicity thiab rehydration zog, thiab yog li siv nyob rau hauv zus tau tej cov noodle khoom.

(1) Daim ntawv thov hauv ncuav

Vim muaj cov pab pawg hydrophilic hauv carboxymethyl cellulose sodium, nws tuaj yeem ua ke nrog dej los tsim cov hydrophilic colloid thiab nqus dej thaum lub khob noom cookie sib xyaw, ua rau muaj peev xwm tuav cov gluten ntxiv. Qhov nthuav CMC Na yog qhov muaj txiaj ntsig zoo rau kev tsim cov qhob cij thiab khaws cov pa roj carbon dioxide thaum lub sijhawm ci, yog li ua kom lub ntim ntawm cov khob cij. Txawm li cas los xij, tus nqi ntawm carboxymethyl cellulose sodium yuav tsum tsis pub tshaj 6%. Vim nws cov dej ruaj khov, qhov tsim nyog ntawm qhov sib ntxiv tuaj yeem txo qhov hardness ntawm qhob cij. Qhov kev sim tau pom tias ntxiv cov nyiaj tsim nyog (2% ~ 8%) ntawm carboxymethyl cellulose sodium tau txhim kho qhov zoo ntawm ci ci, nrog cov txiaj ntsig zoo tshaj plaws thaum ntxiv 6%, tom qab ntawd ntxiv 4%. Nws tuaj yeem ua kom lub ntim ntawm lub khob cij, txhim kho cov qauv thiab tsw ntawm qhob cij, thiab txuas ntxiv lub txee lub neej ntawm lub khob cij. Qhov no muaj peev xwm ntxiv sodium carboxymethyl cellulose rau khob cij los txhim kho nws qhov zoo.

(2) Kev siv hauv kev tsim khoom ntawm Mantou

Qhov sib ntxiv ntawm sodium carboxymethyl cellulose muaj me ntsis cuam tshuam rau pH nqi ntawm nplej Mantou mov paj. Kev tshawb fawb qhia tau hais tias sodium carboxymethyl cellulose tuaj yeem txhim kho kev ntxhib los mos ntawm cov nplej Mantou, thiab txo cov tawv tawv, adhesion, thiab chewiness ntawm Mantou. Thaum qhov sib ntxiv ntawm sodium carboxymethyl cellulose yog {{0}}.06% ~ 0.08%, txhua qhov kev ntxhib los mos ua tau zoo tshaj plaws. Txawm li cas los xij, daim ntawv thov ntawm sodium carboxymethyl cellulose hauv Mantou tseem tsawg dua, uas tseem muaj peev xwm ua tau rau nws daim ntawv thov hauv cov teb tshiab thiab tuaj yeem nce nws daim ntawv thov ntau.

 

3.Lwm daim ntawv thov

Khoom noj khoom haus thickeners muaj cov yam ntxwv ntawm thickening, thickening, stability, ntsev tsis kam, thiab kub tsis kam, thiab yog dav siv nyob rau hauv cov zaub mov seasoning. Qee cov kws tshawb fawb tau kawm txog kev xaiv cov thickening tus neeg sawv cev thiab cov txheej txheem optimization nyob rau hauv kev npaj ntawm natural nqaij essence. Cov txiaj ntsig tau pom tias 5% carboxymethyl cellulose raug xaiv los ua cov colloid ntawm cov nqaij, rhuab thiab yaj hauv dej da dej ntawm 60 ~ 70 degree, stirred rau 30min, yaj lub colloid, tso rau 24 ~ 48h, swelled thiab ces siv los npaj. nqaij tsw monosodium glutamate. Cov khoom muaj cov khoom zoo thickening, tsis muaj xim thiab tasteless.

Vim nws cov nyhuv thickening, sodium carboxymethyl cellulose tuaj yeem siv los ua jam. Tom qab kev sim, nws tau pom tias cov txheej txheem zoo tshaj plaws rau kev ua cov kua txiv lws suav txiv lws suav yog carboxymethyl cellulose sodium 1.9%, citric acid 0.8%, qab zib dawb 4%, thiab qhov sib piv ntawm cov kua txiv hmab txiv ntoo rau cov kua txiv lws suav yog 1:1 ua. Lub resulting jam muaj ib tug zoo saj thiab yog ruaj khov. [1]

Sodium carboxymethyl cellulose kuj tseem siv tau los ua dej haus. Cov pob kws cov dej haus yog qhov yooj yim rau txheej txheej thiab nag lossis daus thaum lub sijhawm khaws cia, thaum kev sib xyaw ntawm CMC thiab sodium alginate tuaj yeem txhim kho kev ruaj ntseg. Thaum ntxiv 0.05% sodium carboxymethyl cellulose thiab sodium alginate, nag lossis daus ntawm pob kws haus yog qhov tsawg tshaj plaws, thiab stratification tom qab centrifugation tsis pom tseeb. Lub stability yog qhov zoo, uas kuj nteg ib lub hauv paus rau txoj kev loj hlob ntawm pob kws haus dej ua lag luam. Sodium carboxymethyl cellulose kuj tseem siv rau hauv kev tsim cov ice cream thiab qhia meej txog cov dej cawv.
