As a nutrition expert with years of experience in analyzing the effects of cooking on nutrients, I can provide you with a comprehensive answer to your question regarding the impact of heat on vitamin E.
Vitamin E is a fat-soluble vitamin that is essential for various bodily functions, including immune function and cell health. It is known for its antioxidant properties, which help to protect cells from damage caused by free radicals. The stability of vitamin E in food can be influenced by several factors, including heat.
When it comes to the impact of heat on vitamin E, it is important to understand that this vitamin is relatively stable compared to other vitamins. However, it is not completely immune to the effects of cooking. The extent to which vitamin E is destroyed by heat depends on several factors, such as the cooking method, temperature, duration, and the presence of other substances in the food.
Steaming and Boiling: These cooking methods involve the use of water, which can cause some loss of vitamin E, especially if the cooking water is discarded. However, the loss is generally minimal, and steaming is considered a gentle cooking method that preserves nutrients well.
Frying: Frying at high temperatures can lead to a more significant loss of vitamin E, particularly if the oil is reused multiple times. The high heat can cause the vitamin to degrade, and the presence of fats in the cooking oil can also affect the stability of vitamin E.
Microwaving: Microwaving is a quick cooking method that can help to retain nutrients, including vitamin E, as it reduces the exposure time to heat. However, the loss can still occur, especially if the food is overcooked.
Baking and Roasting: These methods can also lead to some loss of vitamin E, but the extent of the loss is generally less than that of frying. The use of fats in these cooking methods can influence the stability of vitamin E.
Grilling: Grilling can cause a moderate loss of vitamin E, especially if the food is charred. The high heat and direct exposure to flames can degrade the vitamin.
It is also important to note that the stability of vitamin E can be affected by other factors, such as the presence of oxygen, light, and certain metal ions. These factors can accelerate the degradation of vitamin E, even during cooking.
In conclusion, while vitamin E is relatively stable and can withstand some heat, it is not completely resistant to the effects of cooking. The loss of vitamin E during cooking can vary depending on the method, temperature, duration, and other factors. To maximize the retention of vitamin E in food, it is recommended to use gentle cooking methods, minimize the use of reused oils, and avoid overcooking.

There's no denying that some nutrients are lost when foods are cooked. ... With the exception of vitamin K and the B vitamin niacin, which are very stable in food, many vitamins are sensitive and are easily destroyed when exposed to heat, air, water, or fats (cooking oils).
