Is this something you have come across and wondered, why does parmesan taste like soap?
It’s certainly not pleasant and definitely unexpected!
So what causes the soapy taste?
Does it mean the parmesan has gone off?
Is there something wrong with your taste buds?
Or was it simply sat next to laundry products in your shopping bag?
Let’s get to the bottom of this soapy parmesan conundrum!
There are several reasons why parmesan may taste like soap, and the main cause could be the enzyme lipase. This is typically found in aged cheeses such as parmesan. It will gradually break down the milk fats, causing a soapy taste. This same enzyme is also responsible for the production of butyric acid, which causes cheese to smell of vomit or sweat. Parmesan can also absorb odors, so a soapy taste may have been caused by the cheese being next to a detergent product. A more unusual reason for parmesan tasting like soap is a result of a sinus infection or gum disease.
What is the Reason for the Soapy Taste of Parmesan?
If you have noticed that parmesan sometimes tastes like soap, then it probably came as a bit of a shock!
It clearly doesn’t happen that often, so what causes it?
The main reason is due to an enzyme called lipase.
Lipase can be deliberately introduced during the cheesemaking process to help coagulate the milk.
It’s similar to rennet in that respect.
It makes the parmesan solidify and is usually found in aged cheese.
However, it can also occur naturally caused by bacteria in milk that is too old.
Consequently, if that milk is used for making parmesan, the lipase will already have started breaking down the fat, and this would be too early in the process.
This leads to the soapy taste of the cheese.
Interestingly, lipase is also responsible for the production of butyric acid.
This is the nasty stuff that makes your parmesan smell like vomit or sweaty feet!
There is another slightly more obvious reason why parmesan sometimes tastes like soap.
Just like other cheeses, it absorbs odors easily.
So, if it happens to have been next to any soap or laundry products in your shopping bag, it could have picked up a soapy odor.
Our taste buds are closely linked to our sense of smell.
So, if you can smell soap as you are eating your parmesan, then it makes it appear as though it tastes like soap.
The soap could also actually still be on the plate you are using to serve the food.
Can Illness or Disease Cause a Soapy Taste?
If you are convinced that parmesan tastes like soap, but your friends or family haven’t noticed, then it could be a side effect of an illness you are suffering from.
For example, gum disease can cause either a soapy or metallic taste in the mouth.
This is likely to be caused by poor hygiene and not brushing your teeth regularly.
Old food could be trapped in the teeth or gums, causing a weird, soapy taste.
Some medications can cause strange reactions, and this is particularly true of antibiotics.
The drugs react with water to create a soapy taste in the mouth.
More serious medical conditions, such as a brain injury or stroke, can affect the way food tastes.
If the brain can’t understand the signals from your taste buds, it won’t detect the expected flavor.
Mental health conditions, including anxiety, can change the way we taste food.
In fact, this perceived soapy taste can make anxiety worse, leading to you anticipating the wrong flavor.
Please consult your healthcare practitioner if you are at all concerned.
You Are Using the Wrong Parmesan Cheese
There are many reasons why parmesan tastes like soap.
It can be due to an enzyme called lipase that breaks down the milk.
Placing parmesan near laundry products could result in the cheese absorbing the odor and affecting the taste.
Certain medical conditions can affect your sense of taste such as a stroke or brain injury.
Unfortunately, no matter what the reason, you’re not really going to enjoy soapy parmesan!
Of course, you may have noticed another flavor, and some people think that parmesan tastes like pineapple.
