Kev sib xyaw cov khoom uas tsis sib xyaw ua ke ua rau muaj kev hloov pauv tshuaj lom neeg ntse heev! Yog tias koj tau sim sib xyaw lawv, koj paub tias roj thiab dej tsis sib xyaw yooj yim. Txawm li cas los xij, nrog kev pab los ntawm cov tshuaj emulsifiers thiab cov tshuaj yaj, qhov kev ua tiav zoo li tsis yooj yim sua no tuaj yeem ua tiav.—tab sis puas yog ob lub taum pauv hauv ib lub plhaub? Yuav luag! Txhua lub ua lub luag haujlwm tshwj xeeb tiag tiag. Khi lub pob tes, cov neeg nyiam kev tshawb fawb, thiab npaj txhij los tshawb nrhiav qhov sib txawv ntawm cov emulsifiers thiab cov solubilizers.
Dab tsi yog ib qhoCov khoom ua kom emulsifier?
Cov tshuaj emulsifiers ua haujlwm ua tus sib phim hauv lub ntiaj teb molecular, txawj khi cov roj molecules thiab cov dej molecules uas feem ntau nyiam nyob sib nrug. Lawv ua haujlwm los ntawm kev txo qhov nro ntawm qhov chaw ntawm cov kua, tsim kom muaj kev sib xyaw ruaj khov hu ua emulsion. Ntawm theem molecular, emulsifiers yog amphipathic.—lawv muaj ib qho hydrophilic (dej-hlub) kawg thiab lwm qhov hydrophobic (roj-hlub) kawg.
Qhov kev sib ua ob no tso cai rau lawv kom lawv nyob nruab nrab ntawm roj thiab dej, tsim ib daim thaiv kev tiv thaiv ib puag ncig cov kua dej thiab tiv thaiv kev sib cais. Cov emulsifiers feem ntau uas koj yuav paub txog suav nrog lecithin pom muaj nyob rau hauv qe qe, nrog rau cov lecithin taum pauv lossis paj noob hlis uas siv dav hauv chocolate thiab cov khoom ci kom ua tiav cov qauv du zoo meej.
Dab tsi yog ib qhoCov tshuaj yaj?
Txawm hais tias feem ntau yuam kev ua cov emulsifiers, cov tshuaj yaj ua lub luag haujlwm sib txawv hauv kev seev cev ntawm kev yaj. Cov neeg sawv cev no zoo heev ntawm kev sib xyaw cov roj tawv ncauj thiab dej kom ua tau cov tshuaj ntshiab uas tsis pom kev sib cais, txawm tias rau lub qhov muag ntse tshaj plaws. Yeej, cov tshuaj yaj ua rau cov roj zoo li ploj mus tag hauv dej.
Lawv ua tiav qhov no los ntawm kev puag ncig cov roj me me nrog lub plhaub sab nraud hydrophilic, qhov tseem ceeb yog zais lawv hauv ib txheej dej kom lawv tuaj yeem yaj yam tsis muaj qhov cim. Cov txheej txheem no tsim cov kua es tsis yog emulsion. Cov tshuaj yaj tuaj yeem pom muaj ntau yam khoom, los ntawm cov tshuaj ntxuav ntsej muag uas tshem tawm cov pleev roj mus rau cov roj tseem ceeb diffusers uas tso cov tshuaj tsw qab yam tsis muaj cov seem; piv txwv li suav nrog polysorbates, cawv thiab ethoxylated compounds.
Qhov Txawv Ntawm Lawv Yog Dab Tsi?
Qhov sib txawv tseem ceeb ntawm cov emulsifiers thiab cov solubilizers yog nyob rau hauv qhov kawg ntawm lawv txoj haujlwm. Cov emulsifiers pab tsim cov qauv tshiab thiab kev sib xws, raws li pov thawj los ntawm cov emulsions ruaj khov tsim thaum cov roj poob qis thoob plaws hauv cov dej. Qhov tshwm sim yog cov khoom uas zoo li pos huab, thiab qhov no tshwm sim vim tias nws puv nrog cov roj me me poob qis sib npaug hauv cov dej ib puag ncig.
Qhov sib txawv, cov tshuaj yaj ua rau cov roj ploj mus rau hauv dej tag nrho, ua lub luag haujlwm tseem ceeb hauv cov khoom uas qhov pom tseeb yog qhov tseem ceeb. Lawv nkag roj rau hauv dej, ua rau cov kua dej ntshiab.
