Coconut Oil Smoking: What's The Science Behind It?

Coconut oil is a popular cooking oil, often touted for its health benefits. However, one issue many home cooks face is the oil smoking when heated in a pan. This phenomenon is due to coconut oil's relatively low smoke point of around 350°F (176°C). When an oil reaches its smoke point, it starts to decompose, releasing toxic fumes and free radicals that are harmful to human health. Therefore, it is essential to choose the right oil for the cooking method, as some oils are better suited to high-heat cooking methods like frying and searing, while others are better for low-heat methods like salad dressings and baking.

Coconut oil has a low smoke point of 350°F

The smoke point of an oil is the temperature at which it begins to smoke and burn. This temperature is important because when oil reaches its smoking point, it not only affects the flavor of the food but also releases toxic and carcinogenic substances. These substances can increase the activity of free radicals in the body, subsequently increasing the risk of developing cancer.

Coconut oil has two main types: unrefined and refined. Unrefined coconut oil has a smoke point of 350°F, while refined coconut oil only begins to smoke above 400°F. This means that while unrefined coconut oil cannot be used for high-heat cooking, refined coconut oil can. However, even with refined coconut oil, it is important to be mindful of the temperatures you are cooking at. If you want to sear your food at very high temperatures, even refined coconut oil may not be suitable.

Coconut oil is a popular choice for cooking due to its health benefits. It is rich in medium-chain triglycerides, which are sought after due to health trends such as the keto diet. Additionally, coconut oil has been shown to reduce bad cholesterol and boost good cholesterol, as well as decrease the risk of brain degeneration. However, despite its health benefits, coconut oil should be used at low to moderate temperatures. For higher temperatures, olive oil or avocado oil are better choices.

Unrefined and refined coconut oils have different smoke points

Coconut oil has become one of the most popular cooking oils worldwide in recent years, and it is also used in skincare and haircare. But not all coconut oils are created equal. Unrefined and refined coconut oils have different properties and are suited to different applications.

The main difference between unrefined and refined coconut oil is how they are processed. Unrefined coconut oil, sometimes called virgin or extra-virgin coconut oil, is made with fresh coconut meat that is pressed to extract the oil. There are two main methods for pressing: dry and wet. The dry method involves drying the fresh coconut with heat before it is pressed with a machine to remove the oil. The wet method presses the fresh coconut through a machine to produce coconut milk and oil, which are then separated. Unrefined coconut oil is solid at room temperature and has a strong coconut flavour and scent. It has a low smoke point of around 350°F (177°C).

On the other hand, refined coconut oil undergoes additional processing to improve its suitability for cooking. It is made with dried coconut meat, which is pressed through a machine to extract the oil. This process uses steam or heat to deodorize the product. The oil is then "bleached" and filtered through clays to remove any impurities or bacteria. Refined coconut oil has a neutral scent and taste, and a higher smoke point of 400-450°F (204-232°C).

Due to their different smoke points, unrefined and refined coconut oils are suited to different applications. Unrefined coconut oil is better for baking, as its lower smoke point is unlikely to affect the quality of baked goods. It can also be used for cooking, but it may require lower temperatures. Refined coconut oil, on the other hand, is ideal for high-heat cooking such as stir-frying, sautéing, roasting, and frying. Its higher smoke point means it can withstand higher temperatures without burning.

In summary, unrefined and refined coconut oils have different smoke points due to the way they are processed. Unrefined coconut oil has a lower smoke point and a stronger flavour and scent, while refined coconut oil has a higher smoke point and a more neutral taste and aroma. When choosing which type of coconut oil to use, consider the intended application and the desired flavour profile.

Coconut oil releases harmful toxins when it burns

Coconut oil is a popular choice for cooking due to its health benefits, such as reducing bad cholesterol and boosting good cholesterol, as well as its unique flavour. However, it's important to be aware that coconut oil has a relatively low smoke point compared to other cooking oils, and heating it past this point can release harmful toxins.

The smoke point of an oil is the temperature at which it begins to smoke and burn. When coconut oil reaches its smoke point, it not only imparts an unpleasant burnt taste to food but also starts to release toxic and carcinogenic substances. These substances can increase the activity of free radicals in the body, leading to a higher risk of developing cancer and other diseases. Therefore, it is recommended to use coconut oil for low to moderate-temperature cooking and opt for other oils with higher smoke points, such as avocado or olive oil, when cooking at high temperatures.

The smoke point of coconut oil depends on its type, with unrefined coconut oil having a smoke point of around 350°F, while refined coconut oil starts smoking above 400°F. This distinction is essential because it determines whether coconut oil can be used for high-heat cooking. Unrefined coconut oil is not suitable for high-heat cooking, as it quickly reaches its smoke point. On the other hand, refined coconut oil can be used for high-heat cooking, but even then, it may have its limitations. It is advisable to perform a test beforehand to ensure that the coconut oil can withstand the desired cooking temperature without smoking.

Additionally, it is crucial to discard coconut oil immediately if it has reached its smoke point, as the potency of the toxic components can increase if the oil is reused. While coconut oil may not be ideal for all high-heat cooking methods, it is still a good choice for deep frying and baking, where temperatures are more controlled and the oil is mixed with other ingredients, preventing it from reaching extremely high temperatures.

In conclusion, while coconut oil offers health benefits and a unique flavour, it is important to be mindful of its smoke point to avoid the release of harmful toxins. By understanding the limitations of coconut oil and combining it with suitable cooking methods and temperatures, individuals can safely enjoy the benefits of this versatile oil.

Refined coconut oil is better for high-heat cooking

Coconut oil is a popular cooking oil that has gained traction in recent years due to its health benefits and versatility. It has a unique ability to switch between liquid and solid forms, and is commonly used as a vegan butter substitute in baking. However, coconut oil has a relatively low smoke point, which can make it unsuitable for high-heat cooking.

The smoke point of an oil is the temperature at which it begins to smoke and burn, rather than just sizzle. When oil burns, it emits carcinogens which can increase the activity of free radicals in the body when ingested, potentially increasing the risk of developing cancer. Coconut oil has a smoke point of around 350°F, which is lower than other oils such as avocado oil (520°F) and refined coconut oil (400-450°F). This means that coconut oil is more likely to smoke and burn at high temperatures, making it less suitable for cooking methods such as frying, searing, or sautéing.

Refined coconut oil, on the other hand, has a higher smoke point than unrefined coconut oil due to undergoing additional processing such as bleaching and deodorizing. This makes it better suited for high-heat cooking applications. Refined coconut oil has a smoke point of 400-450°F, which is significantly higher than unrefined coconut oil. This means that refined coconut oil can be used at higher temperatures without smoking or burning, making it a safer and more suitable option for high-heat cooking techniques.

In summary, refined coconut oil is the better choice for high-heat cooking due to its higher smoke point. It is ideal for cooking methods such as stir-frying, sautéing, roasting, and frying, as it can withstand higher temperatures without burning. Refined coconut oil is also flavourless and odourless, making it a more versatile option that won't impart a coconut taste or smell to your dishes.

Coconut oil is still good for deep frying and baking

Deep-fried foods cooked in coconut oil can be a delicious treat when enjoyed in moderation. Coconut oil is high in saturated fats, which means it is stable and doesn't appear to change quality during deep frying. One study found that even after 8 hours of continuous deep frying at 365°F, coconut oil's quality remained acceptable. Another study showed that coconut oil was still stable after 8 hours of deep frying.

Coconut oil is also a good option for baking, as it has a higher smoke point than extra virgin olive oil and a sweet flavour that many people enjoy. However, it is important to use coconut oil in moderation due to its high saturated fat content.
