3. Cleaning of ultra-high temperature milk fouling -Structural and compositionl changes
Abstract : Fouling is the deposit of proteins and minerals formed on equipment surfaces during the heat treatment of dairy products. The concentrations of the components and the structure of the fouling reflect the processing conditions used. The use of a higher processing temperature, e.g. READ MORE
