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 patterns, making it easy to differentiate between the two. Yellow wood has not been detected so far.
