| Abstract: | 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. |
