D10, D50, and D90 are values of the particle diameter at 10%, 50%, and 90% in the cumulative size distribution, respectively. Values are means of three measurements ± SD. Means with different lowercase letters (a–e) within each column are significantly different (p < 0.05). Percentage increase in D50 is between non-agglomerated and agglomerated gum powders.
