Quick Answers

 

 

What causes a "freezer taste" in vegetables?


Except for green peppers and mature onions, vegetables maintain better quality during freezer storage if they are blanched. Blanching stops the action of enzymes which cause: 
 

  • off-flavors, "grassy" or "hay-like" 
  • toughening
  • discoloration 
  • loss of vitamin A and C


Vegetables frozen without blanching are safe to eat, but undesirable changes in flavor, texture and color will soon become apparent. Vegetables frozen raw should be used within a month or two to minimize these quality changes.
