This is a list of capsaicinoids, a class of compound found in members of the capsicum family. They are the chemical responsible for making chili peppers hot . The heat intensity of capsaicinoids is measured in Scoville heat units (SCU) by the Scoville heat scale .
The scale is named after its creator, American pharmacist Wilbur Scoville, whose 1912 method is known as the Scoville organoleptic test. [3] [4] The Scoville organoleptic test is a subjective assessment derived from the capsaicinoid sensitivity by people experienced with eating hot chilis. [3]
Capsaicin acts as an antifungal agent in four primary ways. First, capsaicin inhibits the metabolic rate of the cells that make up the fungal biofilm. [81] This inhibits the area and growth rate of the fungus, since the biofilm creates an area where a fungus can grow and adhere to the chili in which capsaicin is present. [82]
The Scoville scale is a measure of the hotness of a chili pepper. It is the degree of dilution in sugar water of a specific chili pepper extract when a panel of 5 tasters can no longer detect its "heat". [109] Pure capsaicin (the chemical responsible for the "heat") has 16 million Scoville heat units.
Resiniferatoxin has a score of 16 billion Scoville heat units, making pure resiniferatoxin about 500 to 1000 times hotter than pure capsaicin. [3] [4] Resiniferatoxin activates transient vanilloid receptor 1 (TRPV1) in a subpopulation of primary afferent sensory neurons involved in nociception, the transmission of physiological pain.
The Scoville scale measures the pungency of chili peppers, as defined by the amount of capsaicin they contain. A display of spices in Guadeloupe : some pungent, some not Pungency is not considered a taste in the technical sense because it is carried to the brain by a different set of nerves.

Wilbur Lincoln Scoville (January 22, 1865 – March 10, 1942) was an American pharmacist best known for his creation of the "Scoville Organoleptic Test", now standardized as the Scoville scale. He devised the test and scale in 1912 while working at the Parke-Davis pharmaceutical company to measure pungency , "spiciness" or "capsaicin ...
