Milk Heat Treatments: Temperature Effect on Fouling

The purpose of this work is to examine the effect of heating temperature on milk fouling by comparing the evolution of deposits for three different heat treatments, respectively, pasteurization, sterilization and Ultra-High Temperature treatment. A numerical approach was used to resolve the governin...
