Green vegetables get their colour from chlorophyll, a pigment in the chloroplasts of plant cells. Usually, gases in the gaps between plant cells slightly cloud chlorophyll’s green colour. During cooking this air expands and escapes, making the green colour more vibrant.
How do you keep cooked broccoli bright green?
Use one teaspoon salt per 1 cup of water. Salt provides a “barrier” against carbon dioxide, which prevents chlorophyll from changing color. Make sure that you have enough water in your pot so that all of the broccoli is floating in it.
Why do vegetables get greener when cooked?
It’s because of acidic compounds naturally present in all vegetables. Chlorophyll is protected by walls that keep these compounds at a distance. The walls are damaged during cooking and this allows acidic compounds to come into contact with chlorophyll and change its colour.
How do you keep broccoli green before cooking?

Why did my broccoli turn yellow after cooking?
Overcooking
If you cook broccoli too long, it can turn yellow. To avoid this, cook it until it’s tender but not mushy. Overcooking will break down chlorophyll and give broccoli a yellow appearance. Cooking too long also reduces its nutrient content.
How do you boil vegetables without losing their color?

Why did my broccoli turn brown after cooking?
As the veggies hit the boiling water, volatile acids are released into the water and are carried away in the steam. When the pot is covered, the steam and the acids it contains are forced back into the water. Once there, the acids react with the chlorophyll in the vegetables, turning them an unsightly shade of brown.
What vegetable should not be stored in the refrigerator?

What method of cooking vegetables maintain green pigment texture?
Cooking green vegetables in a large quantity of boiling water as quickly as possible and then stopping the process by plunging them into ice water is the best way to preserve the bright green color. This method is known by the French term a l’anglaise.
How does heat affect color of vegetables?
Heat causes a magnesium atom at the center of each chlorophyll molecule to detach and be replaced by hydrogen atoms. This chemical change in chlorophyll molecules changes their bright green color to a dull gray-green. Acids can also cause chlorophyll to lose a magnesium atom, and become that dull green.
How do you keep broccoli crisp when cooking?

Broccoli, spinach, and lettuce may lose up to 50% or more of their vitamin C when boiled ( 4 , 5). Because vitamin C is water-soluble and sensitive to heat, it can leach out of vegetables when they’re immersed in hot water. B vitamins are similarly heat sensitive.
