As a nutritionist with a focus on vitamin research, I'm often asked about the stability of vitamins in various conditions, including the impact of heat on vitamin C. Vitamin C, also known as ascorbic acid, is a water-soluble vitamin that plays a crucial role in the human body. It is involved in the synthesis of collagen, the absorption of iron, and acts as an antioxidant, among other functions. However, its chemical structure makes it sensitive to certain conditions, including heat.
Heat and Vitamin C Stability
When it comes to the impact of heat on vitamin C, it's important to understand that this vitamin is indeed sensitive to high temperatures. The stability of vitamin C is affected by several factors, including the temperature it is exposed to, the duration of exposure, and the presence of other substances such as oxygen and water.
Temperature Threshold
The statement that vitamin C is destroyed by heat above 70 degrees Celsius is a bit oversimplified. While it is true that high temperatures can degrade vitamin C, the rate of degradation increases significantly at temperatures above 80 degrees Celsius. At this point, the vitamin begins to break down more rapidly. However, it's also important to note that cooking methods and the specific conditions can influence how much vitamin C is lost.
Cooking Methods
Different cooking methods can have varying effects on the retention of vitamin C in food. Boiling, for example, can lead to significant losses due to the leaching of the vitamin into the cooking water, as it is water-soluble. This is particularly true for foods that are cooked for extended periods or at high temperatures. On the other hand, methods such as steaming or microwaving can help to retain more of the vitamin, as they often require less water and shorter cooking times.
Storage and Preparation
To maximize the retention of vitamin C in foods, it's recommended to store fruits and vegetables in a cool, dark place, and to consume them as fresh as possible. Refrigeration slows down the enzymatic processes that can degrade vitamin C. Additionally, keeping produce uncut until ready to use can help to prevent exposure to air, which can also lead to oxidation and loss of the vitamin.
Antioxidants and Acidic Environment
The presence of antioxidants and an acidic environment can help to protect vitamin C from degradation. For example, the natural antioxidants found in many fruits and vegetables can help to stabilize vitamin C, reducing the rate at which it is lost during cooking.
Conclusion
In conclusion, while vitamin C is sensitive to heat and can be destroyed under certain conditions, there are steps that can be taken to minimize losses. Choosing cooking methods that use less heat and water, storing produce properly, and consuming foods as fresh as possible can all help to preserve this important 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, store citrus fruits, tomatoes, juices, broccoli, green peppers, cantaloupe and strawberries in the refrigerator uncut until you need them.
