Effect of Amino Acids Addition on 2-Acetyl-1-pyrroline
Formation in the Aromatic Rice. Schieberle et al. (13) reported
that ornithine found in baker’s yeast was a principal precursor
of 2-acetyl-1-pyrroline during baking, whereas L-proline led to
formation of this compound by B. cereus (12). It was also
reported that 2-acetyl-1-pyrroline was present in aerial parts of
rice plants (15).
