Polysorbate (Tween)
Jun 18, 2021
Polysorbate (Tween) muaj cov haujlwm ntawm emulsifying, stabilizing, dispersing, pab ua npuas ncauj thiab ua kom ruaj khov kho cov qauv siv lead ua ntawm cov roj. Nws yog feem ntau siv ua ke nrog lwm cov emulsifiers. Nws muaj cov hydrophilicity pom tseeb. Vim tias nws lub zog muaj peev xwm hloov cov protein, nws cov txiaj ntsig ntawm kev txo cov kev cuam tshuam ntawm lub cev yog qhov muaj zog tshaj li monoglyceride. Vim tias nws cov thermal stability thiab hydrolysis ruaj khov nyob rau hauv dej, ntxiv rau ntawm lub khob dej khov yuav emulsify, disperse thiab ruaj khov lub mis nyuj khov, thiab nce ntim ntawm lub mis nyuj khov. Cov huab cua yoojyim nkag rau hauv emulsion, tsim cov txheej txheem pore zoo, nce ntau qhov ntim, thiab tsim cov dej khov ua kom ruaj khov nyob rau hauv cov duab thiab muaj cov ntawv tsis xoob.
Kev hloov pauv ntawm monomer emulsifiers nrog cov emulsifiers yog cov txheej txheem kev txhim kho ntawm cov khoom noj khov, niaj hnub no, thiab nws yog qhov tshwm sim hauv kev tsim khoom. Tus nqi ntxiv feem ntau yog 0.1% -0.3%. Lub tshuab hluav taws xob emulsifier tsis yog tsuas yog yooj yim siv, tab sis kuj tuaj yeem tau txais ntau yam tsis zoo ua ke ntawm cov khoom khov. Cov tshuab ua ke emulsifier tuaj yeem ua tiav cov txiaj ntsig zoo hloov protein ntau.
