SHU (Scoville heat units), which is the hottest chilli known to date (see below). 

Oleoresin Capsicum Scoville Heat Units (Appendix VIII) Between 100,000 and 2,000,000, as specified on the label. Oleoresin Caraway Volatile Oil Content Between 10 mL and 20 mL/100 g. 

Scoville Heat Units Determine as directed under Scoville Heat Units, Appendix VIII. 

Standard Solution Add 0.15 mL of the Sample Preparation to 140 mL of the Sucrose Solution, and mix. This solution contains the equivalent of 240,000 Scoville Heat Units. 

Test Solutions If the oleoresin sample is claimed to contain more than 240,000 Scoville Heat Units, prepare one or more dilutions according to the following table ...

Procedure Select five panel members who are thoroughly experienced with this method. Instruct the panelists to swallow 5 mL of the solution corresponding to the claimed content of Scoville Heat Units. The sample passes the test if three of the five panel members perceive a pungent or stinging sensation in the throat.

Apart from the organoleptic determination of pungency (Scoville heat units [239]), the capsaicinoids are determined quantitatively, photometrically or singly best with HPLC (e.g. [240, 241, 242]). The quantitative determination of pelargonic acid vanil-lylamide, which is available synthetically and, therefore, prone to adulteration, is of special importance. This substance is only present in small amounts in genuine mixtures.

One of the few situations requiring a QC panel evaluation is the determination of Scoville heat units. While there are analytical methods available for the determination of capsaicins [15], a sensory approach [16,17] is often still used.
