1 shows the particle volume distributions as a function of the particle
mean diameter for different torque speeds. The duration of the milling
process as well as the ring sieve diameter were retained constant in
all the different grindings. What was finally chosen among all different
torque speeds applied for the olive pit powder types B and C was a
rotor speed of 6.000. Olive pit powder C corresponds to that sieved
using a Vibratory Sieve Shaker (Retsch). Olive pit powders were dried
in an oven for 24 h at 110 °C. Then, the powders were stored inside a
humidity chamber with controlled environmental conditions (low
humidity).
