Abstract

The aim of this study was to clarify the formation mechanism of a potent off-odorant, p- methylacetophenone, from citral under acidic aqueous conditions. An acidic aqueous solution (pH 3.0) containing 10 mg/L of citral was stored at 40° C for 2 weeks. Among the compounds detected in the stored citral solution, 4-(2-hydroxy-2-propyl) benzaldehyde was identified for the first time as a degradation product from citral. The formation of p- ...
