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.
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.

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 ...
Pepper spray, oleoresin capsicum spray, OC spray, capsaicin spray, mace, or capsicum spray is a lachrymator (tear gas) product containing the compound capsaicin as the active ingredient that irritates the eyes to cause burning and pain sensations, as well as temporary blindness. Its inflammatory effects cause the eyes to close, temporarily ...
In 2000, India's Defence Research Laboratory (DRL) reported a Scoville rating for the ghost pepper of 855,000 SHUs, [18] and in 2004 a rating of 1,041,427 SHUs was made using HPLC analysis. [19] For comparison, Tabasco red pepper sauce rates at 2,500–5,000, and pure capsaicin (the chemical responsible for the pungency of pepper plants) rates ...
Capsaicin is the component in peppers that makes them spicy. It's also an irritant, which is why you feel a burning sensation when you eat something spicy. Specifically, capsaicin binds to and ...
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]
A display of hot peppers and the Scoville scale at a supermarket in Houston, Texas. Pungency (/ ˈ p ʌ n dʒ ən s i / ⓘ) refers to the taste of food commonly referred to as spiciness, hotness or heat, [1] [2] [3] found in foods such as chili peppers. Highly pungent tastes may be experienced as unpleasant.
