Quantitative analysis of 2-aminoacetophenone in off-flavored wines by stable isotope dilution assay.
Isotope dilution analysis was used to quantitate 2-aminoacetophenone in wines exhibiting the so-called untypical aging off-flavor. d3-Aminoacetophenone was synthesized and used as isotopomeric internal standard. The method of quantitation was verified by several model experiments. In the off-flavored wines studied, amounts of 2-aminoacetophenone ranging from 0.7 to 12.8 micrograms/L were determined.
