Dab tsi yog qhov cuam tshuam ntawm cov khoom noj emulsifier ntawm khov nab kuab zoo?

Cov emulsifier tuaj yeem txo qhov nro ntawm cov dej khov sib xyaw emulsion thiab ua rau cov rog globules tsim cov khoom sib xws thiab ruaj khov zoo ib yam thaum lub sijhawm homogenization txheej txheem ntawm emulsion. Thaum cov txheej txheem khov, cov dej hauv cov khoom siv khov khov hloov mus rau hauv cov dej khov zoo, thiab huab cua nkag mus rau hauv qhov sib xyaw ua npuas me me, thiab cov rog rog uas muaj cov emulsifiers agglomerate los tsim ua peb lub ntsej muag network qauv los tsim lub cev pob txha. ntawm cov mis nyuj khov. Cov dej khov sib xyaw yog cov roj-hauv-dej emulsion: cov roj ntuj thiab lawv cov txiaj ntsig tau nquag siv los ua cov tsis-ionic emulsifiers. Tom qab cov roj tau raug lees paub, ib qhov kawg nqus cov roj molecules thiab lwm qhov kawg nqus dej molecules, uas tuaj yeem tsis tsuas yog txo cov roj-dej interface Kev Nyuaj Siab, lub tshuab muaj zog adsorption zaj duab xis ntau txheej txheej txheej tau tsim ntawm qhov interface, thiab faib ua ntu zus cov khoom tsim ua ob txheej txheej txheej txheej txheej txheej txheej txheej, yog li ua kom tsis txhob muaj kev sib tsoo lossis sib sau ua ke ntawm cov txheej txheem sib faib ua ke nrog tib yam kev them nqi, hloov pauv cov dispersibility ntawm cov rog thiab ua cov khoom tsim cov dej khov zoo thiab ua kom nws cov kev ntxhib los mos du.

Cov emulsifier cuam tshuam ncaj qha cuam tshuam rau txoj kab uas hla siv lead ua hauv cov khoom khov. Ib qho emulsifier uas tsim nyog tuaj yeem txav tau zoo thiab npog cov roj me me uas tau tsim thaum txheej txheem homogenization, yog li cov khoom tuaj yeem tsim ua kom zoo thiab zoo ib yam siv lead ua taub. Nws lub luag haujlwm tseem ceeb hauv cov khoom suav nrog emulsification, ua npuas dej thiab txhim kho cov duab tuav: emulsification feem ntau yog txhawm rau txhim kho kev faib cov roj hauv qhov sib xyaw, kom cov homogenized rog globules nyob hauv ib qho zoo thiab ruaj khov emulsion xeev. , Txhawm rau tiv thaiv cov rog los ntawm ntab thiab sib sau ua ke, thiab tiv thaiv qhov tshwm sim ntawm cov roj ua los ntawm kev siv tshuab thaum lub sijhawm khov thiab ua haujlwm homogenization; foaming yog qhov tseem ceeb los txhawb kev sib cuam tshuam ntawm cov rog thiab cov protein, thiab txhawm rau txhim kho cov yam ntxwv ntawm kev sib xyaw thiab sib xyaw. Kev ua npuas thiab nthuav dav ntawm qhov sib xyaw tuaj yeem txhim kho, thiab kev sib sau ua ke thiab sib koom ua ke ntawm cov rog tuaj yeem tswj tau zoo; kev txhim kho cov duab khaws cia feem ntau yog los ntawm kev ntxiv cov emulsifiers hauv cov dej khov nab kuab, uas tsis yog tsuas yog txhawb nqa huab cua sib xyaw, ua kom ruaj khov thiab cuam tshuam kev ua kom sov, Thiab nws tuaj yeem txhim kho cov cua sov ua kom khov ntawm chav sov, tsim kom zoo dua kua dej khov, tiv thaiv cov khoom kom tsis txhob poob qis, thiab tuaj yeem txhim kho qhov ncauj qhov ncauj thiab tswj kev ruaj ntseg ntawm qhov tsos.
