| Abstract: | A simple and rapid method for the determination of laevulinic acid in soy sauce was developed. Selecting undecanoic acid as an internal standard, the average recovery rate was from 83.4% to 91.2%,and its relative standard deviation was 1.60 %. This method has been successfully applied to the determination of real sample. |
