| 为优化大豆油的脱色工艺，拓展脱色剂在污染物控制方面的应用潜力，采用活性白土或活性白土与活性炭复配对碱炼大豆油进行脱色，考察其对脱臭大豆油中3-氯丙醇酯（3-MCPDE）和缩水甘油酯（GE）生成的影响，并采用活性炭对脱臭大豆油进行吸附处理，考察其对脱臭大豆油中3-MCPDE和GE消减的影响。结果表明：活性白土的pH、平均孔径与脱臭大豆油中3-MCPDE和GE含量呈负相关，说明采用弱酸性和大孔径的活性白土脱色可以降低脱臭过程中3-MCPDE和GE的生成。活性白土与活性炭复配脱色对降低大豆油脱臭过程中3-MCPDE和GE的生成具有协同作用，其中以活性白土与活性炭质量比8∶ 2时效果最佳。此外，高比表面积和大孔隙体积的活性炭可有效吸附脱臭大豆油中已形成的3-MCPDE和GE，其中对GE的消减作用更明显。在活性炭TY-TQ添加量为油质量的1.5%时，脱臭大豆油中3-MCPDE和GE含量可分别降低至153.26 μg/kg和103.24 μg/kg，消减率分别为31.09%和76.22%。综上，采用活性白土与活性炭复配脱色可有效抑制脱臭过程中3-MCPDE和GE的生成，活性炭可进一步消减脱臭大豆油中的3-MCPDE和GE。 |

| To optimize the decolorization process of soybean oil and expand the application potential of decolorizing agents in pollutant control, activated clay alone or a composite of activated clay and activated carbon was used for the decolorization of alkali-refined soybean oil. The effects of these treatments on the formation of 3-monochloropropane-1,2-diol esters (3-MCPDE) and glycidyl esters (GE) in deodorized soybean oil were investigated. Additionally, activated carbon was employed for the adsorption of pollutant in deodorized soybean oil to examine its effect on the reduction of 3-MCPDE and GE in deodorized soybean oil. The results showed that the pH and average pore size of activated clay were negatively correlated with the contents of 3-MCPDE and GE in deodorized soybean oil, indicating that decolorizing with activated clay with weak acidity and large pore size could reduce the formation of 3-MCPDE and GE during the deodorization process. Activated clay and activated carbon exhibited a synergistic effect in reducing the formation of 3-MCPDE and GE during the deodorization of soybean oil, with the optimal effect when the mass ratio of activated clay to activated carbon was 8∶ 2. Furthermore, activated carbon with high specific surface area and large pore volume could effectively adsorb and reduce the pre-formed 3-MCPDE and GE in deodorized soybean oil, and the reduction effect on GE was more significant. When the activated carbon TY-TQ dosage was 1.5% of the oil mass, the contents of 3-MCPDE and GE in deodorized soybean oil could be reduced to 153.26 μg/kg and 103.24 μg/kg, with reduction rates of 31.09% and 76.22%, respectively. In conclusion, the use of a composite decolorizing agent consisting of activated clay and activated carbon can effectively inhibit the formation of 3-MCPDE and GE during the deodorization process, and activated carbon can further reduce 3-MCPDE and GE in deodorized soybean oil. |
