| Abstract: | Under high temperature and acidic conditions, malondialdehyde and thiobarbituric acid could react to form a pink compound 3,5,5＇ - three methyl oxazole - 2,4 - diketone. Based on this reaction, a method was established to determine malondialdehyde content in duck oil by colorimetry. The recovery of this method was 87.0% - 93.2%, and the detection limit was 0.02 mg/kg. |
