Hauv kev lag luam sib txawv, cov txheej txheem tsim khoom ntawm emulsion txawv heev.Cov kev sib txawv no suav nrog cov khoom siv (sib tov, suav nrog ntau yam khoom siv hauv cov tshuaj), emulsification txoj kev, thiab ntau yam kev ua haujlwm.Emulsions yog dispersions ntawm ob los yog ntau tshaj immiscible kua.High siv ultrasound muab lub zog uas yuav tsum tau disperse ib theem kua (dispersed theem) mus rau hauv ib tug me me tee ntawm lwm theem thib ob (nruam theem).
Ultrasonic emulsification khoomyog ib tug txheej txheem uas ob (los yog ntau tshaj ob) immiscible kua yog sib npaug zos rau tsim ib tug dispersion system nyob rau hauv qhov kev txiav txim ntawm ultrasonic zog.Ib qho kua yog sib npaug sib npaug hauv lwm cov kua los ua emulsion.Piv nrog rau kev siv tshuab emulsification thiab khoom siv dav dav (xws li kiv cua, colloid zeb thiab homogenizer, thiab lwm yam), ultrasonic emulsification muaj cov yam ntxwv ntawm siab emulsification zoo, ruaj khov emulsification khoom thiab tsis muaj zog yuav tsum tau.
Muaj ntau daim ntawv thov kev lag luam ntawmultrasonic emulsification, thiab ultrasonic emulsification yog ib qho ntawm cov thev naus laus zis siv hauv kev ua zaub mov.Piv txwv li, dej qab zib, ketchup, mayonnaise, jam, mis nyuj dag, khoom noj rau menyuam yaus, chocolate, zaub xam lav, roj, dej qab zib thiab lwm yam khoom noj khoom haus sib xyaw siv hauv kev lag luam khoom noj khoom haus tau raug sim thiab siv hauv tsev thiab txawv teb chaws, thiab tau ua tiav. Cov txiaj ntsig ntawm kev txhim kho cov khoom zoo thiab kev ua haujlwm ntawm cov khoom siv, thiab cov dej-soluble carotene emulsification tau ua tiav kev sim thiab siv hauv kev tsim khoom.
Txiv tsawb tev hmoov tau pretreated los ntawm ultrasonic dispersion ua ke nrog kev kub siab ua noj, thiab ces hydrolyzed los ntawm amylase.Ib qho kev sim ib zaug tau siv los kawm txog cov txiaj ntsig ntawm qhov kev kho ua ntej no ntawm kev rho tawm tus nqi ntawm cov khoom noj muaj txiaj ntsig zoo los ntawm txiv tsawb tev thiab physicochemical zog ntawm insoluble dietary fiber los ntawm txiv tsawb tev.Cov txiaj ntsig tau pom tias cov dej tuav lub peev xwm thiab khi dej zog ntawm ultrasonic dispersion ua ke nrog kev kho siab ua noj tau nce los ntawm 5.05g / g thiab 4.66g / g, feem 60 g / g thiab 0. 4 ml / g feem.
Kuv vam tias cov saum toj no tuaj yeem pab koj siv cov khoom zoo dua.
