The Scoville scale is a measurement of pungency (spiciness or "heat") of chili peppers and other substances, recorded in Scoville heat units (SHU). It is based on the concentration of capsaicinoids , among which capsaicin is the predominant component.
Structural formula Name Scoville heat units Abbreviation Reference Resiniferatoxin: 16,000,000,000 RTX [2] [3] [4]Tinyatoxin: 5,300,000,000 TTX or TTN [4]Phenylacetylrinvanil
Like capsaicin, it is an irritant. Nordihydrocapsaicin accounts for about 7% of the total capsaicinoids mixture [2] and has about half the pungency of capsaicin. Pure nordihydrocapsaicin is a lipophilic colorless odorless crystalline to waxy solid. On the Scoville scale it has 9,100,000 SHU (Scoville heat units), [1] significantly higher than ...
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.
Capsaicin is a potent defense mechanism for chilies, but it does come at a cost. Varying levels of capsaicin in chilies currently appear to be caused by an evolutionary split between surviving in dry environments, and having defense mechanisms against fungal growth, insects, and granivorous mammals.

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 ...

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.
