In this study,we developed and validated a method for
determining BA level sin various processed foods using solvent
extraction and qHNMR analysis.This is the first report of the
successful determination o fBA in processed foods using qHNMR.
The proposed method has accuracy,precision,selectiveness,and
linearity in the assessed concentration range.Moreover,itisan
absolute quantification method with SI-trace ability.This method
is also more rapid and simple than the conventional method (the
proposed method :55 min,the conventional method : 125 min).
In addition,the advantage of the method is that no authentic
analyte standard is required for the determination of BA in
processed foods.The LOQ is less than 10% of the maximum usage
levels of all food regulated in Japan and by the Codex General
Standard for Food Additives and also low enough for the purposes
of monitoring BA.There fore,the proposed method is a useful and
practical tool to determine BA in processed foods
