Taw qhia
Kas fes creamer, feem ntau hu ua tsis yog -cov khoom siv mis nyuj los yog kas fes whitener, yog ib yam khoom siv los hloov cov mis nyuj los yog qab zib, feem ntau muaj cov roj zaub, pob kws syrup solids, emulsifiers, thiab stabilizers. Nws lub luag haujlwm tseem ceeb yog kom yaj sai sai hauv kas fes kub, muab lub qhov ncauj qhov ncauj thiab ua kom tawv nqaij zoo ib yam li cov mis nyuj, thaum muab cov txiaj ntsig zoo xws li tsis muaj tub yees, lub neej ntev, thiab lactose - cov khoom pub dawb .
Emulsifiers ua lub luag haujlwm tseem ceeb hauv kas fes creamer. Raws li cov kws tshawb fawb txog zaub mov taw qhia, lub hom phiaj tsim ntawm kas fes creamer yog "siv cov protein tsawg li sai tau kom ua tau zoo emulsify ntau roj". Qhov no yog vim hais tias cov emulsification efficiency ntawm cov protein yog tsawg, tsim cov roj tee loj dua uas tsis tshua muaj txiaj ntsig rau kev ntxuav hniav dawb; thaum cov roj ntsha uas tsim los ntawm me me -molecule emulsifiers tsis ruaj khov txaus. Yog li ntawd, lawv yeej ib txwm siv ua ke. Kab lus no yuav tshawb txog qhov tob ntawm cov yam ntxwv thiab qhov sib txawv ntawm ntau yam emulsifiers hauv kas fes creamer.
Core Functions ntawm Emulsifiers hauv Kas fes Creamer
Hauv kas fes creamer, emulsifiers feem ntau ua cov haujlwm tseem ceeb hauv qab no:
1 Roj-Dej Emulsification thiab System Stabilization
Lub luag haujlwm tseem ceeb tshaj plaws ntawm emulsifiers yog kom sib xyaw cov roj thiab dej tsis sib xws los tsim cov roj ruaj khov - hauv - dej emulsion . Thaum lub sij hawm cov tshuaj tsuag kom qhuav, emulsifiers stabilize cov roj zoo, tiv thaiv cov rog sib sau. Thaum kas fes creamer ntxiv rau kas fes kub, emulsifiers yuav tsum muaj kev ua haujlwm nyob rau hauv ib puag ncig acidic tshiab (chaw pH kwv yees li 4.5-5.5) thiab nyob rau hauv qhov kub thiab txias, tiv thaiv emulsion "flocculation" lossis rog sib cais.
2 Whitening Effect Optimization
Lub peev xwm whitening ntawm kas fes creamer yog ze ze rau qhov loj ntawm cov roj tee hauv cov emulsion. Cov roj me me ua rau lub teeb tawg tau zoo dua, ua kom pom kev pom kev zoo dua. Hom thiab tus nqi ntawm emulsifier ncaj qha cuam tshuam qhov loj ntawm cov roj tee tsim thaum lub sij hawm homogenization, yog li cuam tshuam rau cov khoom lag luam whitening nyhuv.
