As a nutritionist with a focus on vitamin research, I can provide you with a detailed answer regarding the stability of Vitamin B12 when exposed to heat.
Vitamin B12, also known as cobalamin, is a unique member of the B-complex vitamins due to its complex chemical structure and its requirement for a mineral component, cobalt. It plays a critical role in the normal functioning of the brain and nervous system, as well as the formation of red blood cells and the metabolism of every cell in the body.
Heat Stability: Vitamin B12 is indeed known for its heat stability. This means that it can withstand high temperatures without being significantly destroyed. This property is particularly important when considering the cooking and processing of foods that are rich in this vitamin. Many foods, such as meats and dairy products, are often cooked or heated before consumption, and the heat stability of Vitamin B12 ensures that a significant portion of this vitamin can be retained even after these processes.
Sensitivity to Environment: While Vitamin B12 is stable to heat, it is not entirely impervious to all forms of environmental stress. It has been noted that Vitamin B12 can be sensitive in heated acid or alkali solutions. This sensitivity is important to consider in various food processing techniques that might involve such conditions. Additionally, Vitamin B12 is slightly sensitive to light, which suggests that exposure to strong or prolonged light can lead to some degradation of the vitamin.
Chemical Interactions: Vitamin B12 can also be affected by certain chemical interactions. It is destroyed by oxidizing and reducing agents, which are substances that can either donate or accept electrons during chemical reactions. The presence of such agents can lead to the breakdown of the cobalamin molecule. Furthermore, some heavy metals can also have a detrimental effect on Vitamin B12, potentially leading to its inactivation.
Practical Implications: From a practical standpoint, the heat stability of Vitamin B12 is beneficial for those who rely on cooked or processed foods as part of their diet. It means that even after cooking, a good amount of Vitamin B12 can still be present in foods, making it easier for individuals to meet their dietary requirements for this vitamin. However, it is also important to be mindful of the other factors that can affect Vitamin B12 stability, such as the presence of certain chemicals or exposure to light.
Conclusion: In conclusion, while Vitamin B12 is stable to heat, it is not completely stable under all conditions. Its stability can be compromised by certain environmental factors and chemical interactions. Understanding these factors can help in the preservation of Vitamin B12 in food products and ensuring adequate intake of this essential vitamin.

Cobalamin is stable to heat, though sensitive in heated acid or alkali solution, slightly sensitive to light, and destroyed by oxidizing and reducing agents and by some heavy metals. Vitamin B12, a member of the B-complex vitamins, is a water-soluble vitamin that is stable to heat.
