| 旨在有效管控大豆油精炼过程中的风险成分，保障油品质量与安全，研究了邻苯二甲酸二正丁酯（DBP）、邻苯二甲酸二(2-乙基)己酯（DEHP）、邻苯二甲酸二异壬酯（DINP）3种塑化剂在大豆油精炼过程中的迁移情况和脱除规律，并分析了脱臭工艺参数对大豆油中反式脂肪酸(TFA)、3-氯丙醇酯(3-MCPDE)和缩水甘油酯(GE)的影响。结果表明：16种植物油（2 107个批次）中塑化剂污染较为普遍，精炼过程中加工助剂是大豆油中塑化剂的来源之一，其中脱色剂（活性白土和凹凸棒黏土）的塑化剂检出率和迁移率较高；脱臭是大豆油中塑化剂脱除的关键工段，延长脱臭时间及提高脱臭温度均可提高大豆油中塑化剂的脱除率，但会使TFA、3-MCPDE、GE的含量上升，且脱臭温度的影响比脱臭时间更明显；脱臭温度240 ℃、脱臭时间60 min条件下，大豆油中DBP的脱除率达98%，DEHP、DINP脱除率与250 ℃时的峰值差异不大，且TFA、3-MCPDE、GE的含量较低。综上，脱色剂引入塑化剂的风险较大，需重点关注；建议脱臭温度不超过240 ℃，通过改变脱臭时间来控制大豆油中风险成分含量。 |

| To effectively manage the risk components during the soybean oil refining process and ensure the quality and safety of oil, the migration and removal patterns of three plasticizers, di-n-butyl phthalate (DBP), bis(2-ethylhexyl) phthalate (DEHP), and diisononyl phthalate (DINP), were investigated during the soybean oil refining process. Additionally, the effects of deodorization process parameters on trans-fatty acids (TFA), 3-monochloropropane- 1,2-diol esters (3-MCPDE), and glycidyl esters (GE) in soybean oil were analyzed. The results showed that phthalate contamination was relatively common in 16 types of vegetable oils (2 107 batches). Processing aids during refining were one of the sources of phthalates in soybean oil, among which decolorizing agents (activated clay and attapulgite clay) exhibited relatively high detection rates and migration rates of phthalates. Deodorization was the key processing stage for the removal of phthalates from soybean oil. Prolonging the deodorization time and increasing the deodorization temperature could improve the removal efficiency of phthalates in soybean oil, but resulted in a higher contents of TFA, 3-MCPDE and GE. Moreover, the effect of deodorization temperature was more significant than that of deodorization time.At deodorization temperature 240 ℃ and deodorization time 60 min, the removal rate of DBP in soybean oil reached 98%, and the removal rates of DEHP and DINP were not significantly different from their peak values at 250 ℃, while the contents of TFA, 3-MCPDE and GE remained at low levels. In conclusion, decolorizing agents pose a relatively high risk of phthalates introduction and require close attention. It is recommended that the deodorization temperature should not exceed 240 ℃, and the contents of risk components in soybean oil should be controlled by adjusting the deodorization time. |
