While preparing lemonade, Sanika added fresh lemon juice into boiling hot water. Her grandmother advised her to add lemon juice only after the water cools down. What scientific reason supports her grandmother's advice?
Heat converts Vitamin C into toxic compounds
Vitamin C gets easily destroyed by heat
Citric acid evaporates completely in warm water
Boiling water removes calcium needed for Vitamin C action
Solution
Vitamin C is heat-sensitive and breaks down rapidly at high temperatures, reducing the nutritional benefit of the lemon juice.
