Explain about the Blanching - Food Processing?

Blanching is used for variety of purposes. It is defined as a mild heat treatment applied to tissue (usually plant) prior to freezing, drying or canning. Why do we need to blanch foods? 

Well, blanching is useful and its functions include:

  • Inactivate most enzymes
  • Some cleaning action
  • Removes substances in some products
  • Activates some enzymes (if controlled)
  • Removes undesirable odors/flavors
  • Softens fibrous material and decreases volume
  • Expels air and respiratory gasses
  • Preheating of product prior to canning
