Blanching is a must for most vegetables to be frozen. It slows or stops the enzyme action which can cause loss of flavor, color and texture. The blanching time is very important and varies with the vegetable and size.
Which is better blanching or steaming?
What’s the Difference Between Boiling and Steaming? … Steam blanching, which takes a few minutes longer than your average blanching time, typically maintains more of the nutritional value than water blanching, dropping vegetables straight into boiling water, where nutrients can get extracted and lost forever.
Why do we blanch broccoli?

Is the water from boiled vegetables healthy?
Water in which vegetables have been boiled contains minerals as well as vitamins that naturally leak from the cooking plant cells. (Steaming is better for us nutritionally because it leaves more of those minerals and vitamins in the vegetables, but there are still some nutrients in water used for steaming.)
How do you boil vegetables without losing nutrients?
To retain these vitamins, cook vegetables in as little water as possible for a minimal amount of time (unless you’re planning to consume the water, as in a soup). Steaming and microwaving, both of which use little water, will give you the same results as boiling or blanching but with much less nutrient loss.
Do the water from boiled vegetables have nutrients?
Vegetables provide essential vitamins, minerals and fiber and are low in calories when prepared correctly, such as. … The leftover water after cooking leafy greens like spinach and lettuce and cruciferous vegetables such as broccoli and kale also contains nutrients and can be used in other recipes.
Why are potatoes cooked in cold water?
