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.
The heat intensity of capsaicinoids is measured in Scoville heat units (SCU) by the Scoville heat scale. [1 ... Capsaicin: 16,000,000 CPS [8] Dihydrocapsaicin ...
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 ...
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.

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.
Like capsaicin it is an irritant. Homocapsaicin accounts for about 1% of the total capsaicinoids mixture [2] and has about half the pungency of capsaicin. Pure homocapsaicin is a lipophilic colorless odorless crystalline to waxy compound. On the Scoville scale it has 8,600,000 SHU (Scoville heat units). [1]
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.
Dihydrocapsaicin is a capsaicinoid and analog and congener of capsaicin in chili peppers . Like capsaicin, it is an irritant. It accounts for about 22% of the total capsaicinoid mixture [2] and has the same pungency as capsaicin. [1] Pure dihydrocapsaicin is a lipophilic colorless odorless crystalline to waxy compound.
