Dab tsi cuam tshuam ntawm cov khoom noj emulsifier ntawm cov khoom noj dej khov?

Cawv ntawm cov zaub mov emulsifier rau cov khoom noj qab zib zoo:

Cov emulsifier tuaj yeem txo qhov tsis sib haum ntawm cov dej khov dej sib xyaw emulsion thiab ua rau cov rog npuag tsim cov teeb meem sib luag thiab ruaj khov zoo thaum lub txheej txheem homogenization ntawm cov emulsion. Thaum lub sijhawm ua cov txheej txheem khov, cov dej hauv cov khoom noj khov ua rau cov dej khov ua kom zoo, thiab cov huab cua nkag rau qhov sib xyaw ua ke ua cov npuas me me, thiab cov roj ntsha uas muaj emulsifiers agglomerate tsim cov qauv txheej txheem peb lub voos xwm txheej los ua lub cev pob txha. ntawm lub mis nyuj khov. Cov dej khov ua ke yog cov roj-hauv-dej emulsion: cov roj ntuj thiab nws cov khoom siv sib xyaw ua ke yog siv los ua cov tsis muaj ionic emulsifiers. Tom qab cov roj yog esterified, ib qho kawg nqus cov roj molecules thiab lwm qhov kawg nqus cov dej molecules, uas tsis tuaj yeem tsuas yog txo cov roj-dej interface Tension, lub tshuab muaj zog adsorption zaj duab xis txheej txheem ntau txheej txheem tsim nyob ntawm qhov kev sib tshuam, thiab cov theem dispersed. hais ua ob txheej txheej hluav taws xob txheej tsim qauv, thiaj li zam tau qhov kev sib tsoo lossis qhov sib cais ntawm cov roj tawg kom tawg nrog cov khoom sib txawv, hloov kev faib tawm ntawm cov roj thiab ua kom cov khoom tsim cov dej khov zoo zoo nkauj thiab ua kom nws txoj kev ntxig du.

Cov emulsifier cuam tshuam ncaj qha cov siv lead ua txoj kev faib khoom hauv cov khoom noj khov. Cov emulsifier uas tsim nyog tuaj yeem hloov mus nyob zoo thiab npog cov roj cov roj ntsha uas tau ua thaum ua cov txheej txheem homogenization, yog li cov khoom lag luam tuaj yeem tsim ua kom zoo thiab sib npaug siv lead ua cov khoom faib. Nws lub luag haujlwm tseem ceeb hauv cov khoom suav nrog emulsification, ua npuas ncauj thiab txhim kho cov duab kom zoo: emulsification yog tseem ceeb txhawm rau txhim kho kev sib kis ntawm cov rog hauv kev sib xyaw, yog li homogenized rog globules nyob hauv ib qho zoo sib xws thiab ruaj khov emulsion xeev. , Txhawm rau tiv thaiv cov rog los ntawm ntab thiab agglomerating, thiab tiv thaiv qhov tshwm sim ntawm cov roj me me vim yog siv zog thaum lub sijhawm khov thiab homogenization; ua npuas ncauj yog tsuas yog los txhawb txoj kev sib txuam ntawm cov rog thiab cov protein, thiab txhawm rau txhim kho cov yam ntxwv ntawm kev sib xyaw thiab sib tov. Kev ua npuas ncauj thiab nthuav dav ntawm qhov sib xyaw tuaj yeem txhim kho, thiab kev sib xyaw thiab kev sib xyaw ua ke ntawm cov rog tuaj yeem tswj tau zoo; kev txhim kho ntawm kev ua kom zoo dua qub yog qhov tseem ceeb vim muaj kev txhim kho emulsifiers nyob rau hauv cov dej khov nab kuab, uas tsis tsuas yog txhawb cov huab cua sib xyaw, ua kom ruaj khov thiab cuam tshuam rau kev hloov tshav kub, Ntxiv mus, nws tuaj yeem txhim kho qhov kub tsis kam ntawm cov dej khov ntawm chav tsev txias, tsim kua nyeem ua kua, ua tau zoo tiv thaiv cov khoom kom tsis txhob ploj, thiab tuaj yeem txhim kho lub qhov ncauj solubility thiab tswj kev ruaj ntseg ntawm cov tsos.
