3.3 Particle size distribution and -potential
Figure 1 shows the typical particle size distribution obtained for one of
the milks (almond) as affected by the homogenisation and thermal
treatments. Similar behaviour was found for hazelnut milks.

Figure 1. Typical particle size distribution curves for the untreated and treated
almond milks in terms of percentage of volume (a,c) and percentage of number of
particles (b,d). (MF = homogenised samples; HH = High Heat treated samples; LH =
Low Heat treated samples; MF3HH and MF3LH= samples homogenised at 172 MPa
and high and low heat treated, respectively).
