The measurement was conducted at the room temperature at 25ºC. The
recorded time, namely solubility was indicated in the unit of minute. Then, the solution was test by using the pH
meter, refractometer and chromameter. For the moisture content, the powder will determined by moisture analyzer.
5 g of powder is put in the moisture analyzer at 105 ºC for 10 minutes. Then take the reading of moisture content at
the moisture analyzer. Next for the particle size, the powder was measured by using Malvern particle size analyzer.
