What is the proper time to blanch green beans before freezing? One person said 1 minute and another said 3 minutes. Also, can I put them in a freezer bag or do I need actual freezing containers?

Blanch for at least 3 minutes if pre-cut into 1 inch pieces. Longer 3-5 minutes if whole. Plunge them into ice cold water for the same amount of time as you blanched them to bring the temperature down. Drain/dry the beans well before using. Use about 1 gallon of water per 1 lb. of green beans. You can use freezer bags as long as you get as much air as you can out of them. I don't recommend hard containers as the air can cause freezer burn.

Why is it necessary to blanch vegetables prior to freezing? Why can't I just wash, drain, cut, and freeze the raw green beans?

I think you can but the blanching, if I remember correctly helps to keep frost from forming on them. The proper procedure is to blanch them for one minute, plunge them in ice water for a minute then lay them on a towel to dry.

It is worth it if you have a better product in the end.

It's to preserve the color, keep crisp yet tender and halts the enzymes that deteriorates the nutritional value of the food during storage. Also, assorted veggies need different amounts of blanching time. For instance, beans should be blanched for 3 minutes, corn on the cob for 4 minutes and beets anywhere from 25 to 50 minutes depending on their size. All varieties of onions and peppers do not need to be blanched.

Blanching vegetables and sometimes fruits is necessary before freezing to destroy enzymes and bacteria that could cause spoilage. It also helps to preserve a vibrant color on the frozen product. Plunging the vegetables in ice water stops the cooking process.

And I don't blanch greens either,but you must get all the air out of it. But on all beans and peas I wouldn't blanch. Happy Day.

How do I blanch vegetables, such as corn?

Wiser ones might correct or add to my answer, but blanching as I understand such is merely placing the food (usually fresh vegetables or fruits) into a pot of boiling water for 1-2 minutes and then immediately submerging them into ice water to stop the cooking process. I use the process when preparing fresh vegetables (such as corn on the cob) for freezing.

It also works well when preparing a batch of fresh tomatoes for processing as after you remove the tomatoes from the ice water, you can literally slide off the skins with your hands. Good Luck!

If I remember right there are different directions for different types of food. As far as freezing tomatoes goes, all most of the people that I know, do is wash them, remove the stems and toss them in a plastic bag and then into the freezer. Then when they get a few more tomatoes they do the same thing, adding them to the previous bag.

KansasCindy's response gives the correct definition of blanching. However, the blanching time varies depending on the vegetable. Some require no more than 1-2 minutes; others may require 3 minutes or more.

Thriftyfun has a guide to blanching on the website. You could also consult the Ball Book of Canning and Perserving for information.

Why do we blanch veggies before freezing?

To stop the enzymes in the foods. Otherwise the food will continue to ripen and become mush.

I think the blanching breaks down the plant cells. Then the moisture in them does not freeze and burst, that changes the texture of the food.

Blanching slows or stops the action of enzymes which cause loss of flavor, color and texture. Blanching also cleanses the surface of dirt and organisms, brightens the color and helps retard loss of vitamins.

Blanching also wilts or softens vegetables and makes them easier to pack.

Blanching stops the enzyme action and give far superior frozen veggies, that's why it is suggested that you do it. You'll live if you eat the veggies without blanching them, especially if they are frozen for only a short time.
But after putting so much work into growing them, don't you want your veggies to actually taste good and be in prime condition when you finally choose to eat them, and more so if you spend your hard-earned dollars on them? It's best not to take any short-cuts when putting food up.
