  1. 1–5: Samples of acid whey powder with poor solubility. a–c: Samples of fat filled milk (FFMP). Average values are based on all particles for each sample. Distribution is based on the counts within an interval, compared to the total data array for a specific descriptor. Dn is based on number/count weighted distribution of particles, and not volume (Dv), for cumulative percentages 10, 50 and 90.
