This standard specifies the methods for the determination of BHA and BHT in foods such as cakes and vegetable oils. This standard applies to the determination of BHA and BHT in foods such as cakes and vegetable oils. The detection limit of this method: the detection amount by gas chromatography is 2.0 μg, and the detection concentration is 4.0 mg/kg when the oil sampling amount is 0.50 g. The detection amount by colorimetry is 10.0 μg, and the detection concentration is 4.0 mg/kg when the oil sampling amount is 0.25 g. The best linear range of gas chromatography: 0.0μg~100.0μg.
