A method to analyze calcium propionate in food was developed by capillary gas chromatography (CGC), using free fatty acid phase (FFAP) capillary column and a flame ionization detector (FID). While external standard method was used for quantitative analysis and had a good linearity in the concentration range of 5txg/mL -250μg/mL. The average recovery was 93.2%, the relative standard deviation was 1.5% (n =6) and the limit detection was 2.8μg/mL.
