Cheese is a beloved dairy product, but sometimes, it can taste like soap. This strange phenomenon can occur due to various factors, including the cheese's proximity to laundry products, the presence of the enzyme lipase, or even issues with oral hygiene. In some cases, it could also be a sign of a medical condition or a rare gene variant. While a soapy taste in the mouth is usually temporary and harmless, it can be unpleasant and affect the enjoyment of food. Understanding the reasons behind this soapy flavour can help cheese enthusiasts avoid or mitigate this issue, ensuring a more pleasant culinary experience.

What You'll Learn
Cheese may have absorbed detergent odours
Cheese is a food product that can easily absorb odours from its surroundings. This is especially true for certain varieties of cheese, such as Parmesan. If cheese is stored or transported near laundry products or soap, it can absorb these detergent odours, which may then be perceived as a soapy taste when the cheese is consumed.
The perception of a soapy taste in cheese can also be influenced by factors related to an individual's taste buds and sense of smell. Our taste buds are closely linked to our sense of smell, so if a person smells soap as they are eating cheese, it can seem as though the cheese itself tastes like soap. This perception can be subjective, as some people may be more sensitive to certain odours or flavours than others.
In some cases, a persistent soapy taste in the mouth, known as dysgeusia, can be a symptom of an underlying medical condition or medication use. For example, gum disease, poor oral hygiene, or a sinus infection can cause a soapy or metallic taste in the mouth. Additionally, certain medications, such as antibiotics, can leave a soapy taste that can interact with the flavour of cheese.
To avoid cheese absorbing detergent odours, it is recommended to store cheese away from laundry products and to check the wrapping for any suspicious odours that may transfer to the cheese.

Variant in the gene OR6A2
The perception of soapiness in cheese can be attributed to various factors, one of which may be linked to the variant in the gene OR6A2. This gene encodes for olfactory receptor 6A2, a protein that interacts with odorant molecules in the nose, triggering the perception of smell.
Olfactory receptor proteins, including OR6A2, are part of the G-protein-coupled receptor (GPCR) family, which arises from single coding-exon genes. These receptors share a 7-transmembrane domain structure with neurotransmitters and hormone receptors. They are responsible for recognizing and transducing odorant signals, thereby contributing to our sense of smell.
The OR6A2 gene variant has been implicated in the divergent reactions to the smell and taste of coriander, also known as cilantro. Some people enjoy it, while others find it repulsive. This gene variant may also influence the perception of other odours and tastes, including the soapy taste sometimes associated with cheese.
While the exact mechanism is not fully understood, it is speculated that the OR6A2 gene variant affects how the olfactory receptors interact with certain odorant molecules, leading to variations in smell and taste perception. This could explain why some people are more sensitive to the soapy taste in cheese, while others may not detect it at all.
Additionally, it is worth noting that the perception of soapiness in cheese can also be influenced by external factors. For example, cheese can absorb certain smells from its surroundings, such as nearby soap or detergent. Overripe cheese can also develop a soapy taste due to the activity of the enzyme lipase, which produces butyric acid and contributes to a rancid, soapy flavour.

Poor oral hygiene
While there are many reasons why cheese might taste like soap, one of them is poor oral hygiene.
Studies have shown that hospitalized elderly patients with poor oral hygiene, high growth of oral bacteria, and dry mouth had significantly reduced taste ability. Their ability to perceive sweet, salty, and sour tastes was particularly affected. Poor oral hygiene can also cause dental problems such as caries and decayed teeth, which can further impair taste.
Additionally, poor oral hygiene can be a sign of underlying medical conditions or treatments, such as cancer and cancer treatments like chemotherapy or radiation therapy. These can also impact taste buds and the sense of taste. Furthermore, certain medications, including antibiotics, antidepressants, and allergy medications, can also alter one's sense of taste.
Practicing good oral hygiene is essential for maintaining taste buds and the sense of taste. This includes brushing teeth twice a day, flossing, and visiting a dentist regularly for check-ups and cleanings. Proper oral hygiene can help prevent dental problems and maintain overall health and quality of life.

Sinus infection or gum disease
There are several reasons why cheese may taste like soap. Firstly, it could be due to the proximity of the cheese to soap or laundry products, which can cause the cheese to absorb the odor and affect its taste. This is especially true for aged cheeses, where the enzyme lipase, responsible for coagulating the milk, can produce butyric acid, contributing to a soapy smell and taste.
In some cases, a sinus infection can cause a soapy taste in the mouth, affecting the perception of cheese and other foods. Additionally, gum disease or poor oral hygiene can leave old food trapped in the teeth and gums, resulting in a soapy or metallic taste. Certain medications, such as antibiotics, can also interact with food or water to create a soapy taste. Furthermore, more serious medical conditions, such as a brain injury or stroke, have been known to affect the way food tastes, including the sensation of soapiness.
It is important to consider various factors, such as recent dietary habits, medications, and health history, to determine the cause of the soapy taste. While a soapy taste in the mouth is typically temporary, it can sometimes indicate an underlying medical concern. If the soapy taste is accompanied by other symptoms, it is advisable to seek medical advice to rule out any potential illnesses or conditions.

Arsenic poisoning
The symptoms of arsenic poisoning vary depending on the duration and level of exposure. Acute poisoning can cause symptoms similar to food poisoning, including abdominal pain, nausea, vomiting, and watery diarrhea that may contain blood. These symptoms can occur within hours of exposure. Long-term exposure can lead to more severe health issues, including thickening and darkening of the skin, abdominal pain, diarrhea, heart disease, numbness, and cancer. Neurological symptoms, such as headache, delirium, encephalopathy, and seizures, may occur in the subacute phase, weeks after exposure, or even hours in some cases.
There is no specific treatment for long-term arsenic poisoning, and acute poisonings are treated by addressing dehydration. Some medications, such as dimercaptosuccinic acid or dimercaptopropane sulfonate, may be used, while hemodialysis can also be considered in certain cases.
To prevent arsenic poisoning, it is essential to avoid exposure to arsenic. This includes using water that does not contain high levels of arsenic, which can be achieved through special filters or rainwater collection. Additionally, avoiding direct contact with contaminated soil or surfaces treated with arsenic-based preservatives is crucial.
