Dab tsi yog Compound Emulsifiers?
Hauv ntiaj teb kev ci, emulsifiers ua lub luag haujlwm tseem ceeb. Txawm li cas los xij, ib qho emulsifiers feem ntau muaj kev txwv - qee qhov ua tau zoo ntawm kev muag muag, qee qhov ntawm kev ntxiv dag zog gluten, qee qhov ntawm cov roj khaws cia, tab sis nws nyuaj rau ib qho emulsifier los npog tag nrho cov haujlwm. Qhov no coj peb mus rau hnub no tus protagonist:Cov tshuaj emulsifiers.
Compound emulsifiers yog cov khoom tsim los ntawm kev sib xyaw ob lossis ntau hom sib txawv ntawm emulsifiers hauv qhov tshwj xeeb. Los ntawm kev tshawb fawb compounding, sib txawv emulsifiers tuaj yeem tsimkev sib koom ua ke, achieving "1+1>2 "txoj kev.
Vim li cas thiaj siv Compound Emulsifiers?
1 Kev kov yeej cov kev txwv ntawm Ib Leeg Emulsifiers
Txhua emulsifier muaj nws cov qauv molecular tshwj xeeb thiab HLB tus nqi (Hydrophilic-Lipophilic Balance). Piv txwv li, Glycerol Monostearate (GMS) yog lipophilic emulsifier nrog HLB tus nqi ntawm kwv yees li 3.8, ua tau zoo ntawm kev khi nrog cov hmoov txhuv nplej siab los tiv thaiv retrogradation; thaum Sucrose Esters (SE) muaj ntau HLB ntau yam (3-16), tso cai xaiv hom hydrophilic lossis lipophilic raws li xav tau. Kev sib xyaw emulsifiers nrog qhov sib txawv ntawm HLB qhov tseem ceeb tuaj yeem tsim cov yeeb yaj kiab uas muaj kev ruaj khov dua, tiv thaiv kev sib koom ua ke.
2 Ua tiav ntau yam haujlwm
Bakery khoom muaj ntau qhov yuav tsum tau ua rau emulsifiers: softening, ntim nce, kev ntxhib los mos txhim kho, txee lub neej ncua. Compound emulsifiers tuaj yeem ua tau raws li tag nrho cov kev xav tau ib txhij. Kev tshawb fawb qhia tau hais tias los ntawm emulsifier compounding, ntau yam kev cov nyom uas ib leeg emulsifiers tsis tuaj yeem daws ib leeg tuaj yeem daws tau, xws li kev txhim kho emulsion stability, txhim kho kev ntxhib los mos thiab qhov ncauj, thiab ua rau muaj kev ntxhov siab rau ib puag ncig.
3 Txo kev siv tag nrho, txhim kho tus nqi-Kev ua tau zoo
Los ntawm kev sib xyaw ua ke, cov teebmeem kev sib koom ua ke ntawm emulsifiers tuaj yeem ua tiav cov txiaj ntsig zoo ntawm kev siv qis dua. Piv txwv li, kom sib xyaw lipophilic Span 60 nrog hydrophilic Polyglycerol Esters tuaj yeem txo cov kev siv emulsifier los ntawm 20% -40%.
