The standard used to calibrate the calculation is 1 gram of capsaicin. Scoville heat units are found by multiplying the ppmH value by a factor of 15. [5] [a] By this definition of ppmH, spicy compounds other than the two most important capsaicinoids are ignored, despite the ability of HPLC to measure these other compounds at the same time. [5]

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 ...
The fruit tends to be very pungent and registers 30,000 to 50,000 on the Scoville heat unit scale. ... Download as PDF; Printable version; In other projects Wikimedia ...
[5] [12] The sensory heat or pungency detected when eating a Carolina Reaper derives from the density of capsaicinoids, particularly capsaicin, which relates directly to the intensity of chili pepper heat and Scoville Heat Units (SHU).
Like the closely related habanero, scotch bonnets have a heat rating of 100,000–350,000 Scoville units. [ 8 ] [ 10 ] For comparison, most jalapeño peppers have a heat rating of 2,500 to 8,000. A completely sweet variety of scotch bonnet, cachucha , is grown on some Caribbean islands.
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 modern Scoville unit *per se* is not imprecise at all. t is defined by 1 Scoville unit = 1 part of capsaicinoids per 15 million, and it is now determined precisely by a chemical test called high performance liquid chromatography -- and these facts appear in the article.
