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] List of capsaicinoids. Structural formula Name
The technique utilizes high-performance liquid chromatography to identify and measure the concentrations of the various compounds that produce a heat sensation. Scoville units are roughly 1 ⁄ 15 the size of pungency units while measuring capsaicin, so a rough conversion is to multiply pungency by 15 to obtain Scoville heat units. [108]
The degree of heat found within a food is often measured on the Scoville scale. [14] There has long been a demand for capsaicin-spiced products like chili pepper, and hot sauces such as Tabasco sauce and Mexican salsa. [14] It is common for people to experience pleasurable and even euphoric effects from ingesting capsaicin. [14]
Moreover, shogaol (and gingerol) are converted to other constituents when heat is applied over time, which is why ginger loses its spiciness as it is cooked. The name shogaol is derived from the Japanese name for ginger (生姜、shōga). Shogaol is rated 160,000 SHU on the Scoville scale. [1]
[7] [8] It was later claimed through media outlets such as the Associated Press that an individual Carolina Reaper had a heat level of 2.2 million SHU. [ 7 ] [ 9 ] [ b ] Currie eventually bred an even stronger pepper—known as " Pepper X "—that took the title of "World's Hottest Pepper" on August 23, 2023 that was tested indicating an ...
Scoville heat units (SHU) is a common indication of pepper spiciness. It does take into account the different potency of CRC compounds, but it cannot be reliably used in pepper spray because it measures the strength of the dry product, i.e. the OC resin and not what comes in the aerosol spray.
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.
