The vitamin most readily destroyed by heat is – |
A. | Riboflavin |
B. | Ascorbic acid |
C. | Tocopherol |
D. | Thiamine |
Answer» B. Ascorbic acid | |
Explanation: Vitamin C (Ascorbic Acid) is the most easily destroyed vitamin. It is destroyed by oxygen, heat (above 70 degrees) and it leaks out into the cooking water because it is a water soluble vitamin. To preserve vitamin C in food, citrus fntits, tomatoes, juices, broccoli, green peppers, cantaloupe and strawberries should be stored in the refrigerator uncut until we need them. Steaming and stir-frying are two methods that help conserve vitamin C content. |
