Physical and Engineering Characteristics of Skim Milk

Skim milk is a by-product obtained during the separation of cream from milk. It is rich in solid-not-fat content and has high nutritional value. The physical and engineering properties of skim milk can provide necessary information for the optimal design of unit operations of the manufacturing process and thereby quality control of final products. In addition, the characterization of food system is important to establish relation between flows and correlate physical parameter with sensory evaluation. Flow behavior of food products has a tremendous importance since these properties are determinant factors in equipment design, quality control and unit operations such as pumping, homogenization, blending, cooling, pasteurization, sterilization, evaporation and dehydration etc. In innovation of new technologies for processing of skim milk, the physical, flow and rheological characteristics are important.
