RESUMO
During transport of milk in three-cell tank truck, the vibrating acceleration ranged generally on the level of 0.5 to 2g (0.5 to 20 m/s2) at the vibrating frequency 2 to 60 Hz. The vibration increased proportionally to the driving speed of tank truck, being dependent on the type and surface condition of road and the efficiency of space filling in the container, with lower vibration levels at lower filling.

Model studies are presented on the influence of vertical and horizontal vibrations of different frequency (10 to 60 Hz), constant acceleration 1 g, and constant exposition time 60 min on changes in the lipid fraction of milk. It was found that the changes in the examined characteristics of milk fat were dependent on and intensified with the frequency.
