| Abstract: | The method for the determination of phenolic compounds residues in milk podwer was developed. The phenolic compounds residues were extracted from milk podwer samples with acidity water. The extracts were purified with hexane and potassium carbonate solution, and then acetic anhydride was added. Phenolic compounds were derivatized and submitted to determined with gas chromatography equipped with electron - capture detector （GC - ECD） and confirmed with GC/MS. The recoveries were in the ranges of 75. 8% - 93.5% and the RSDs was in the ranges of 2.61 % - 4. 8%. The detection limits of the phenolic compounds were in the range of 0. 5 - 1. 5 μg/kg. |
