A Comparison of Emulsion Stability as Non-Dairy Coffee Whitener Preparation

비 유지방 분말크림 제조시 유화 안정성의 비교

This study was carried out to investigate the effect of the emulsion stability according to the quantity of emulsifiers and the pressure of homogenizer in coffee whitener preparation. The results of this study are as follow : 1. To obtain a standard emulsifier, the ratio of mono and triglycerides(Atoms 150), sorbitan monostearate (Span 60) and polyoxylene(20) sorbitan monostearate(Tween 60) was 60 . 20 : 20 and the optimum quantity was about 0.9fS for stable emulsion. 2. Characteristics as coffee whitner were markedly improved when the pressure of homogenizer was 200∼250kg1cmz and homogenizing times are over 4. 3. The good whitening capacity was showed when fat glouble's average diameter was under 0.5 Um.
