Shogaols are pungent constituents of ginger similar in chemical structure to gingerol. The most common of the group is [6]-shogaol. Like zingerone, it is produced when ginger is dried or cooked.[2] 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] When compared to other pungent compounds, shogaol is moderately more pungent than piperine, but less than capsaicin.
