| Abstract: | A rapid headspace-gas chromatography/mass spectrometry method was developed for the determination of methanol in food additives. Good linearity （r^2 〉0.9990） for the calibration curve was obtained, and the limit of deteclion （LOD）） for methanol was 0. 80 mg kg, and the limit of quantification （LOQ） for methanol was 2.07 mg/kg. Satisfactory recoveries （96.37% to 99.95 % for methanol） were achieved. The method was proved to he simple and accurate.and has been applied in the determination of methanol in food additives. |
