Zingerone, also called vanillylacetone, is the principal organic compound responsible for giving ginger its pungent taste. It is a crystalline solid that is sparingly soluble in water, but soluble in ether.

Zingerone is similar in chemical structure to other flavor chemicals such as vanillin and eugenol. It is used as a flavor additive in spice oils and in perfumery to introduce spicy aromas.

Fresh ginger does not contain zingerone; cooking the ginger transforms gingerol, which is present, into zingerone through a retro aldol reaction.

Ginger compounds have been shown to be active against enterotoxigenic Escherichia coli heat-labile enterotoxin-induced diarrhea . This type of diarrhea is the leading cause of infant death in developing countries. Zingerone is likely the active constituent responsible for the antidiarrheal efficacy of ginger. [1]

Its synthesis from vanillin can be found in one of the experiments of the Home Chemistry Society: Preparation of Zingerone from vanillin
