The physical properties of the liquid emulsions before spray drying are critical to the





encapsulation to the lipids. The amount of the emulsifier may affect to microstructure in





stabilization of the emulsions. It may affect in physical stability powder after





reconstitution. The optimum emulsifier has means that the minimum concentration to





sufficient in stability emulsion spray dried after reconstitution. This study determined the





effects of the emulsifier concentrations on the microstructure and physical stability





emulsions of spray dried coconut milk powder. The freshly prepared coconut milk without





adding water blend with sodium caseinate (0,1,2,3 and 5% w/v) at 10% (w/v) maltodextrin





as to be wall material. And then it was pasteurized by heated in at 70oC for 1 min and after





that homogenization at two stages. The emulsion had spray dry and analysis of emulsion





before and after spray dry reconstitution in particle size, microscopy and creaming index.





The increasing concentration of the emulsifier showed the decreasing of oil droplets and





increasing of the surface oil. The optimum emulsifier concentration was found to be 3 %





(w/v) sodium caseinate which resulting in the stabilization of the creaming behavior after





reconstitution and also it had smallest particle size (d3.2 = 0.98 μm).This study showed that





the amount of the emulsifier affected to stabilization of the spray dried coconut milk





emulsion. The sufficient amount of protein would be stability of the fat globules, thus





resulted the stability of the spray dried powder coconut milk after reconstitution.
