Abstract:
      With alkali-deacidified maize oil as raw material, the removal effects of zearalenone (ZEN) by different types of activated carbon were investigated. On the basis of single factor experiment, with dosage of activated carbon, adsorption temperature and adsorption time as independent variables, ZEN removal rate as response value, the adsorption conditions were optimized by response surface methodology. The results showed that H-1 activated carbon had the strongest adsorption capacity for ZEN. The optimal adsorption conditions were obtained as follows: dosage of H-1 activated carbon 25%, adsorption temperature 80?℃ and adsorption time 20 min. Under the optimal conditions, the removal rate of ZEN in maize oil was (87.11±0.64)%.
