The contents of 2-acetyl-4-tetrahydroxybutylimidazole (THI) in commercial caramel I, III, and IV were determined as the data used to establish the specifications of caramel colors. In caramel III, which is obtained by adding ammonium compounds, all products contained THI in the range of 0.72-7.3μg/g. However, in caramel IV, which is obtained by adding ammonium and sulfite compounds, no products contained THI. On the other hand, in caramel I, which contains neither ammonium nor sulfite compounds, a tiny peak that may be THI was observed in 1 product.
