Micrographs of milk samples are shown in Figure 1.
As shown in Figures 1a-j, as the ultrasound power levels
and exposure times increased, the distribution of fat
globules was more stable and smaller fat globule
diameters were obtained. It was difficult to observe the
fat globules at a power level of 100 for 10 min (Figure
1j) because of breakage into very small fragments.
