Scoville scale

The creator of the famous Scoville scale is Wilbur Lincoln Scoville, an American chemist who thought to measure the spiciness inside the single chili. The SHU (Scoville Heat Units) is used to indicate capsaicin

The chili extract was diluted with water and sugar to verify its Scoville gradation. The more diluted the substance obtained, the hotter the chilli. At least 5 people have to taste the product and the goal is to find the zero point.

With the advancement of technology, new and more sophisticated means were born, HPLC (High performance liquid chromatography) measures capsaicin with very sophisticated and precise methods.
