What is the Pungency?

The definitions of the pungency are ‘Sharp, piercing, stinging, biting or penetrating quality’ or ‘power 10 excite or stimulate’ and also it can be referred as ‘the total content of Capsaicinoids.’  The Capsaicinoids is the collection of capsaicin, homocapsaicin, dihydrocapsaicin and nordihdrocapsaicin. It is produced in the gland that is located in the union of the placenta with the fruit wall and accumulated in vacuoles of the epidermal cells in the fruit. 


The Scoville Scale

The Scoville Scale is used to determine the pungency of fruits of the genus capsicum (chilis and peppers) based on the capsaicinoids concentration. American pharmacologist, Wilbur Scoville was the inventor of the Scoville scale. Here, prepared chili sample that is tested by a panel of testers and diluted with water repeatedly until they no longer burned the tongues of the tasters. Based on the no. of dilutions required to kill the heat, a number is assigned to the chili pepper. Currently, SHU like subjective method is not used to check the pungency level. It has replaced by High Performance Liquid Chromatography (HPLC).
