Determination method of acetohydroxamic acid in wheat flour and flour treatment agent thereof |
| abstract |
The invention discloses a method for measuring acetohydroxamic acid in wheat flour and a flour treating agent thereof. Belongs to the technical field of chemical analysis. The method comprises the following steps: extracting a sample; purifying and analyzing; drawing a standard curve; and (5) qualitatively and quantitatively identifying the sample. The invention detects acetohydroxamic acid based on gas chromatography technology, and the acetohydroxamic acid is extracted by ethanol C 18 Purifying with solid phase extraction column, filtering, detecting with gas chromatograph equipped with nitrogen and phosphorus detector, and determining with retention time of gas chromatography and external standard method. The method is simple and convenient, has high sensitivity, and is very suitable for measuring the acetohydroxamic acid in the wheat flour and the flour treating agent thereof. The detection limit is 10 mg/kg; the limit of quantitation was 30 mg/kg. |
