Some foods sting or burn the tongue due to the presence of chemical compounds like capsaicin in peppers or alkaloids in hot peppers. These substances activate pain receptors in the tongue, causing the sensation of burning or tingling.
Peppers are foods that cause a burning sensation on the tongue and in the mouth. This sensation is due to the presence of capsaicin, a chemical compound found naturally in peppers. Capsaicin activates pain receptors in the mouth, called TRPV1 receptors. When capsaicin interacts with these receptors, it sends a burning signal to the brain, thus causing the sensation of intense heat.
The spicier a pepper is, the higher its capsaicin content. The spiciest varieties of peppers, such as Cayenne pepper or habanero pepper, contain a greater amount of capsaicin than milder varieties, such as bell pepper.
Capsaicin found in peppers also has beneficial effects on health. It is known for its anti-inflammatory, analgesic properties, and even for its positive effects on metabolism. This is why capsaicin is often used in traditional medicine to relieve pain and treat certain conditions.
In conclusion, the burning sensation experienced when eating peppers is caused by capsaicin, a chemical compound naturally present in these foods. This sensation can vary in intensity depending on the amount of capsaicin contained in the pepper.
Wasabi, a very spicy green paste widely used in Japanese cuisine, contains chemical compounds called isothiocyanates. These isothiocyanates, especially allyl isothiocyanate, are responsible for the intense heat and tingling sensation experienced when consuming wasabi. Allyl isothiocyanate is released when the wasabi root is cut, grated, or chewed.
Isothiocyanates act by stimulating pain receptors in the mouth, sending signals to the brain indicating a sensation of heat. This reaction is a natural defense mechanism of plants, as isothiocyanates deter herbivores from consuming the plant due to the burning sensation they cause.
In addition to its unique and strong taste, wasabi is also known for its antibacterial and antifungal properties. The isothiocyanates present in wasabi have shown beneficial effects on health, such as boosting the immune system and fighting inflammation.
It's important to note that authentic wasabi is quite rare outside of Japan, and many products marketed as wasabi are actually mixtures of horseradish, mustard, and food coloring. However, for an authentic and spicy culinary experience, nothing beats real wasabi and its isothiocyanates.
Black radish contains glucosinolates, sulfur compounds that give it its characteristic spicy taste. When we chew black radish, the enzymes present in our mouth will break down these glucosinolates, releasing volatile molecules. These molecules will stimulate pain receptors on the tongue, giving the sensation of burning or spiciness. This reaction is a natural defense mechanism of the plant to deter herbivores from consuming it. Glucosinolates in black radish also have beneficial antioxidant and anti-inflammatory properties for human health.
Lemon contains citric acid which is responsible for its tangy flavor. Citric acid can irritate the taste buds on the tongue, causing a tingling or burning sensation. This reaction can be amplified if the oral mucosa is slightly irritated or damaged. Citric acid is sometimes used as a food additive for its acidic taste and its ability to prolong the shelf life of foods. Sensitivity to lemon and citric acid can vary from one person to another depending on their individual tolerance and taste sensitivity.
The hottest chili in the world is the Carolina Reaper, measuring over 2.2 million units on the Scoville scale, which measures the strength of peppers.
Foods like wasabi and horseradish can cause a temporary burning sensation by stimulating the pain receptors on the tongue.
Some animals, such as birds, do not have pain receptors related to spiciness on their tongue, allowing them to eat very spicy foods without feeling a burning sensation.
Some spicy foods contain chemical compounds like capsaicin, isothiocyanate, or acids, which activate pain receptors on the tongue.
Capsaicin interacts with pain receptors on the cells of the tongue, causing an increase in the sensation of heat and burning.
Wasabi contains isothiocyanates that cause a more intense but shorter-lasting burning sensation than chili peppers, which contain capsaicin.
No, the burning sensation caused by certain foods is generally harmless and can even be beneficial for health due to their antioxidant properties.
Drinking milk, eating bread or fatty foods, or consuming acidic foods like lemon can help neutralize the burning sensation on the tongue.
