Effect of wall materials proportion on powder moisture content
It can be observed from Cox trace plot (Fig. 8A) that the MC of
microencapsulated powders decreased as the amount of MD and
GA decreased and GE increased from reference blend. As shown in
Fig. 8B, the effect of GA and GE on MC was similar to 30% TS. While
the MC of powders varied as the amount of MD decreased from
reference blend. Thus, the wall material type and ratio can influence
the MC of microencapsulated powders. In contrast to our results,
Dian, Sudin, and Yusoff (1996) reported that MC values for
microencapsulated palm oil by spray drying method were not
affected by the type of wall material.
