| Abstract: | The benzoic acid and sorbic acid in food were analyzed with capillary gas-chromatography. The samples were extracted with aether, and vaporized to nearly dry. The residue was dissolved with chloroform and analyzed with gas-chromatography: FFAP quartz capillary column, 220℃, and dimethyl phthalate (inner mark). A good linear range of the two compounds was found between 0.25～4.00mg/mL. |
