Description
A research team studied how ultraviolet light breaks down the tingling compounds in Sichuan pepper extract, in this 2023 paper. The extract's flavor comes from a family of compounds called sanshools, but how they change under light was poorly mapped. The team purified three sanshools from the extract for testing.
Under UVB light like that in sunlight, the main compound faded fast, following a clean decay pattern. All three compounds partly rearranged into new forms with the same mass, and one new compound appeared. The changes depended on the solvent used. The findings give producers guidance on how light exposure during processing and storage can alter the pepper's signature tingle.
