分子蒸馏脱除核桃油中塑化剂工艺优化Optimization of removal of plasticizers from walnut oil by molecular distillation

为探索利用分子蒸馏脱除核桃油中塑化剂的合理工艺，采用单因素实验考察了蒸馏温度、进料速度和刮膜转速对核桃油中塑化剂DEHP和DBP脱除的影响，在此基础上以DEHP和DBP的含量为指标，运用响应面法对分子蒸馏脱除核桃油中塑化剂的工艺条件进行优化。结果表明：分子蒸馏脱除核桃油中塑化剂的最佳工艺条件为蒸馏温度150 ℃、进料速度250 mL/h、刮膜转速260 r/min，在此条件下核桃油中DEHP含量为0.56 mg/kg，DBP含量为0.05 mg/kg,符合我国对食品中DEHP、DBP的限量要求（DEHP≤1.5 mg/kg， DBP≤0.3 mg/kg）。In order to explore...
