Learn how to blanch vegetables and why it's important. A list of
vegetable blanching times is at the bottom of this page.
Why should you blanch vegetables?
- Cleans off surface dirt and microorganisms
- Keeps the color bright
- Helps retain vitamins
- Reduces the action of enzymes which can destroy the fresh flavor after four weeks
- Shrinks the product, making packing easier
Vegetables used for their flavor such as green onions, hot peppers, and herbs do not have to be blanched.
