Effect of dextrose equivalent (DE) of maltodextrin (MD) on the reconstituted emulsion stability of emulsified
hydrated coconut oil (HCO) in spray-dried powder was investigated. HCO-encapsulated powders
were produced with MDs of DE 2, 10, and 25 as wall material and sugar stearic acid esters (SSE) as
emulsifier. The reconstituted emulsion from MD of DE 10 was less stable than those from MDs of DE 2
and DE 25. The increase rates of average diameter of reconstituted oil-droplet could be correlated by
the zero-order reaction model. By FT-IR and powder X-ray diffraction measurement, spectrum results
suggest a stronger interaction between MD of DE 10 and SSE compared to the other two MDs. The
interaction between the surfactant and MD is important to select the wall material to form spray-dried
powder with a stable reconstituted emulsion.
