Study Notes
Cream Separation Process
- The key objective of the cream separation process is to separate milk fat from skim milk.
Importance of Fat Separation
- Understanding the basics of fat separation is crucial for an optimal de-creaming process.
Properties of Milk Fat
- The specific density of milk fat is 0.93 g/cm³.
Natural Creaming
- Natural creaming has no industrial significance because it is a slow process that requires a long period of time.
Principle of Cream Separation
- Cream separation is possible due to the difference in specific densities between milk fat (0.93 g/cm³) and skim milk (1.03 g/cm³).
- The differences in densities allow for cream separation based on gravity or centrifugation.
