| Abstract: | Two pretreatment methods were used in benzoic acid determination in soy by HPLC.The result of determination indicated that the recovery for sample diluted directly ranged from 98.8%to103.5%,and the recovery for sample extracted with aether ranged from 95.4%to98.4%.The residual deviation of these two methods was less than10%.The methods accord with inspection requirement though some deviation exists. |
