 Brief Info

Although this type of pepper does not rank very high on the Scoville heat scale, it still produces a burning sensation. This sensation comes from a chemical compound in the pepper called capsaicin. Capsaicin is mainly present in the ribs and seeds of the fruit pod. This chemical compound is also erratically present throughout the entire pod. High Performance Liquid Chromatography is performed to determine the amount of heat a chili pepper contains. The chemical compound, Capsaicin, is used for this test.

The original test was developed and performed in 1912. Wilbur Scoville, a chemist, used a group of people as taste testers. He would have them to taste a mixture of sugar water and chili pepper. He continued to further dilute the mixture, with sugar water, until the individuals could no longer feel the burning sensation on their tongues. The particular number of dilutions was used to create a ranking on the scale.
