摘  要:
[Objective] To improve pretreatment quality of simultaneously determination of antioxidants BHA,BHT,TBHQ. [Method] To study and improve pretreatment method for simultaneously determination of antioxidants BHA,BHT,TBHQ in food by capillary column gas chromatography. [Result] After the samples were methanol vortex oscillation extraction,freezing filtration purification method can effectively remove the oil and all kinds of impurities. The recovery rate was from 95% to 101%,The limits of detection were 1 mg / kg. [Conclusion]The pretreatment method has advantages of fast,high efficient,precision and recovery rate,which is suitable for carrying out large quantities of product inspection work.
