Excitation Emission Matrix (EEM) spectroscopy can easily identify turmeric due to its high fluorescence and clear, consistent pattern. Another yellow colorant thought to have been traditionally used, [[Amur cork tree|Japanese yellow wood]] or kihada also fluoresces very brightly but they give very distinctive EEM spectra making it easy to differentiate between the two. Yellow wood has not been detected so far.

Kamakura Village by Katsushika Hokusai

Turmeric 鬱金(ukon): A yellow dye obtained from the root of the Curcuma domestica (or C. longa) plant native to India and southeast Asia. Turmeric made its way to Japan through Okinawa by way of China from Thailand. The primary color component in turmeric is curcumin.

Turmeric and orpiment have been the most commonly detected yellows as a single colorant as well as a mixture of the two. Turmeric produces a bright yellow with high tinting strength. (flavonoids also commonly found?)

Analysis

Excitation Emission Matrix (EEM) spectroscopy can easily identify turmeric due to its high fluorescence and clear, consistent pattern. Another yellow colorant thought to have been traditionally used, Japanese yellow wood or kihada also fluoresces very brightly but they give very distinctive EEM spectra (or plot?) making it easy to differentiate between the two. Yellow wood has not been detected so far.
