Dear the thermal stability of vitamin C is within the range the temperature range of 30 to 90 °C. Melting point of ascorbic acid 190-192 Celsius . Hello, Vitamin C is very stable if heated in complete absence of oxygen, even at 100°C.
What temperature does vitamin C tolerate?
Vitamin C and Heat Vitamin C begins to denature with exposure to temperatures as low as 86 degrees Fahrenheit, according to a study done by N.C. Igwemmar, S.A. Kolawole, I.A. Imran in the International Journal of Scientific and Technology Research.
Is vitamin C stable in heat?
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.
Is vitamin C affected by temperature?
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.
At what temperature is vitamin C best retained?
The temperature was kept at a constant, low temperature of 140°F. The researchers concluded the study with this recommendation: “For high retention of vitamin C while cooking it is recommended that the vegetables are cooked in low heat and small amounts of water for short periods to minimize the loss of vitamin C.”
