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. Minimum detection concentration: The minimum detection amount by gas chromatography is 2μg, and the minimum detection concentration is 4mg/kg when the oil sampling volume is 0.5g. The minimum detection amount of the colorimetric method is 10 μg, and the minimum detection concentration is 4 mg/kg when the oil sampling volume is 0.25 g.
