| 中文摘要: |
| 以碱炼脱酸玉米油为原料，考察了不同型号活性炭对玉米赤霉烯酮(ZEN)的吸附脱除效果。在单因素试验的基础上，以活性炭添加量、吸附温度、吸附时间为自变量， ZEN脱除率为响应值，采用响应面法优化了吸附条件。 结果表明：H-1活性炭（油脂专用活性炭）对ZEN的吸附能力最强；最佳吸附条件为H-1活性炭添加量2.5%、吸附温度80?℃、吸附时间20 min；在最佳吸附条件下，玉米油中ZEN脱除率为（87.11±0.64）%。 |
| 英文摘要: |
| 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 25%, 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)%. |
