Coconut oil is known for its sweet, mild coconut aroma. However, some people have reported experiencing coconut oil that smells like cheese, bacon grease, or blue cheese. This unusual smell can be caused by the growth of mould or fungus, specifically Penicillium roqueforti, which is commonly used in the production of blue cheeses. Consuming rancid coconut oil can be unsafe and may have serious health implications. It is important to discard coconut oil that has gone bad and not use it for any purpose, including topical application.

Coconut oil can go rancid due to oxidation, creating methyl ketones also found in blue cheese
Coconut oil is known for its long shelf life and is generally resistant to spoilage. However, under certain conditions, coconut oil can go rancid, which can result in an unpleasant odour. One of the reasons coconut oil can turn rancid is due to a process called oxidation.
Oxidation is a natural chemical process where compounds interact with oxygen in the air, leading to degradation and the formation of new substances. In the case of coconut oil, oxidation can occur over time, especially if the oil is exposed to heat, light, or moisture. This process can lead to the creation of methyl ketones, which are compounds that give off a distinctive cheesy smell, reminiscent of blue cheese.
Methyl ketones are also found in blue cheese due to the presence of a fungus called Penicillium roqueforti, which is intentionally added during the cheese-making process to impart its characteristic aroma and flavour. This fungus is commonly found in nature, including in soil, decaying organic matter, and plants. While it plays a beneficial role in cheese production, its growth in coconut oil is undesirable.
The presence of methyl ketones in rancid coconut oil is a clear indication that the oil has degraded and is no longer safe for consumption or topical use. Using rancid coconut oil can have serious health implications, potentially increasing the number of free radicals in the body, which are linked to inflammatory issues, cardiovascular diseases, cell damage, and even cancer. Therefore, it is important to discard coconut oil that exhibits signs of rancidity, such as an unusual cheesy or pungent odour.

Consuming rancid coconut oil is not safe and can cause cell damage and increase free radicals in the body
Coconut oil is known for its superior shelf life stability compared to other oils due to its fatty acid composition and overall nutrient profile. However, when coconut oil goes rancid due to oxidation over time, it can develop an unpleasant odour resembling that of blue cheese. This occurs through the creation of methyl ketones, which are also found in blue cheese and are responsible for their characteristic aroma.
Consuming rancid coconut oil can have serious health implications. Rancid coconut oil contains fungal toxins that are not destroyed by heat during cooking. These toxins can cause cumulative damage to the liver and increase the number of free radicals in the body. Free radicals are associated with inflammatory and cardiovascular diseases, as well as cell damage and cancer. The health consequences of consuming rancid coconut oil may not manifest immediately but can have long-term effects.
Therefore, it is essential to discard coconut oil that has gone bad and not use it for cooking or any other purpose, including topical application. Rancid coconut oil should be replaced with fresh, high-quality coconut oil, ensuring it is stored properly to prevent oxidation and prolong its shelf life. Proper storage includes keeping the oil in an airtight container, away from direct sunlight, and in a cool, dry place.
Additionally, it is important to purchase coconut oil from reputable sources and check the expiration dates to minimize the risk of consuming rancid oil. While pure coconut oil typically has a light coconut aroma, it should not be confused with the smell of rancidity, which can be identified as a strong, unpleasant odour.
In summary, consuming rancid coconut oil is unsafe and can lead to cell damage and an increase in free radicals in the body, potentially causing serious health issues. It is crucial to recognize the signs of rancidity in coconut oil and take the necessary steps to prevent and address it.

Pure coconut oil should have a light coconut smell and be solid when cool
Coconut oil is known to have a long shelf life and does not spoil easily. Pure coconut oil should have a light, pleasant coconut aroma and be solid when cool. However, some coconut oils may have a stronger coconut smell, while refined coconut oil tends to be neutral or almost odourless.
If your coconut oil smells like cheese, it is likely that it has gone rancid. Rancidity in coconut oil can be caused by oxidation over time, which produces methyl ketones. These compounds are also found in blue cheese and are responsible for its distinctive smell. Consuming rancid coconut oil is not safe as it can increase the number of free radicals in the body, leading to inflammatory and cardiovascular issues, cell damage, and even cancer.
In one instance, a user reported that their coconut oil had a cheesy odour due to slight fungal growth. The fungus Penicillium roqueforti, commonly found in blue cheese, may have contaminated the oil, giving it a cheesy smell. It is important to note that most fungal toxins are not destroyed by cooking heat, and they can cause cumulative liver damage.
To avoid any health risks, it is recommended to discard coconut oil that has developed an unpleasant odour, as it cannot be used for cooking, topical application, or any other purpose. Always check the expiration date of your coconut oil and store it properly to ensure its quality and safety for intended use.
It is worth mentioning that some coconut oils, especially those purchased from Indian stores, may have a thick, gritty texture and an unpleasant smell, such as old bacon grease. This may be due to improper refining or the presence of other ingredients. If you encounter such issues, it is advisable to switch to a different brand or source your coconut oil from a different supplier.

Refined coconut oil is neutral and can be odourless, even years after its expiration date
Coconut oil is known for its long shelf life and is resistant to spoilage due to its fatty acid composition and nutrient profile. However, it can still go rancid due to oxidation over time, resulting in the creation of methyl ketones, which are also found in blue cheese and are responsible for its distinctive aroma. This phenomenon is often attributed to the growth of the fungus Penicillium roqueforti, commonly used in the production of blue cheeses.
While coconut oil is generally expected to have a pleasant, mild coconut aroma, some people have reported experiencing unusual smells, such as old bacon grease, in their coconut oil. These unpleasant odours can be attributed to various factors, including improper storage, oxidation, or fungal contamination.
In contrast to unrefined or virgin coconut oil, refined coconut oil is known for its neutral characteristics. It often has little to no scent and can retain this odourless quality even years after its expiration date. This makes it a popular choice for use in cooking, as it does not impart any noticeable flavour or aroma to the dishes it is used in. Additionally, refined coconut oil is widely used in beauty products as a carrier oil, as its neutral properties allow it to blend seamlessly with other ingredients without altering their scent.
It is important to note that consuming rancid coconut oil can have adverse health effects. Rancidity indicates the presence of free radicals, which have been linked to inflammatory issues, cardiovascular diseases, cell damage, and even cancer. Therefore, it is recommended to discard coconut oil that exhibits unusual smells or other signs of spoilage.
