Do I Need To Blanch Before Freezing?

What happens if you don’t blanch before freezing?

Blanching helps vegetables keep their vibrant colors and retain nutrients, and stops the enzymes that would otherwise lead to spoilage. Freezing vegetables without blanching them first results in faded or dulled coloring, as well as off flavors and textures.

What food should be blanched before freezing?

Blanching is a process in which you boil or steam vegetables briefly until they are partially cooked. It is an essential step before freezing many vegetables including broccoli, leafy greens, string beans, okra, and asparagus.

Why is blanching necessary?

Blanching stops enzyme actions which otherwise cause loss of flavor, color and texture. In addition, blanching removes some surface dirt and microorganisms, brightens color and helps slow vitamin losses. It also wilts greens and softens some vegetables (broccoli, asparagus) and makes them easier to pack.

Is blanching vegetables good or bad?

If you cook vegetables gently -- and without a great deal of water -- you will help protect the water-soluble vitamins. Filardo recommends blanching your veggies, which is when you quickly cook vegetables in boiling water, and remove them when they're still very crisp, to help preserve the color and nutrients.

How do you prepare vegetables for freezing?

Most vegetables need to be blanched before freezing. Place in boiling water and cook for 1-3 mins (depending on the vegetable), then remove with a slotted spoon and plunge into ice cold water to stop the cooking.

Are commercial frozen vegetables blanched before freezing?

In contrast, vegetables that are destined to be frozen are harvested and then immediately steam blanched. This quick exposure to high heat stops the enzymes responsible for deterioration and kills off any unhealthy microorganisms.

Is steaming the same as blanching?

For broccoli, pumpkin, sweet potatoes and winter squash, both steaming and boiling are satisfactory methods. Steam blanching takes about 1½ times longer than water blanching. To steam, use a pot with a tight lid and a basket that holds the food at least three inches above the bottom of the pot.
