Durand et al. (2003) investigated stability of milk and of different vegetable beverages, including soymilk. All samples were treated by commercial UHT process and changes in backscattering intensity were analyzed during 12 h of measurements. They observed that
milk and soymilk samples did not exhibit sedimentation phenomenon,as reveled by this study, but slight amount of creaming in the surface of the sample. Creaming phenomenon was attributed to the
tendency of oil droplets to coalesce by the large particles in the floating portion at the top of the tube.
