The retention of vitamin C ranged from 0.0 to 91.1% for all cooked samples. Generally, higher retention of vitamin C was observed after microwaving with the lowest retention recorded after boiling.
Will vitamin C content remain the same after cooking?
Vegetables are generally a great source of vitamin C, but a large amount of it is lost when they're cooked in water. In fact, boiling reduces vitamin C content more than any other cooking method. Broccoli, spinach, and lettuce may lose up to 50% or more of their vitamin C when boiled ( 4 , 5).
Does vitamin C get destroyed by cooking?
Vitamin C can be destroyed by heat and light. High-heat cooking temperatures or prolonged cook times can break down the vitamin. Because it is water-soluble, the vitamin can also seep into cooking liquid and be lost if the liquids are not eaten.
Does heat completely destroy vitamin C?
Vitamin C is easily destroyed by excessive heat and water, as well as exposure to air. For retention of vitamin C in cooked foods, it is recommended that foods containing vitamin C be cooked as fast as possible with less heat and small amount of water.
How can you save vitamin C when cooking?
Vitamin C is lost in cooking water and during long storage times. You can preserve vitamin C by cooking the food in very little water (like steaming or microwaving) and by eating fresh vegetables and fruit as soon as possible.
