Mass Balances

Learning Outcomes

At the end of this module, you will be able to:

  1. draw system diagram identified with its boundary
  2. use the law of conservation to conduct a mass balance
  3. conduct a mass balance on a given operation or a processing line

In this module, we will first discuss the need for material and mass balances in food processing operations and use the law of conservation of mass to develop expressions and steps useful for conducting a mass balance. In the following video, you will learn how to perform a material balance. The importance of system boundaries will be evident in this analysis.


In this module, you learned expressions for mass and material balances and a stepwise procedure on how to conduct a balance for a given operation.
