| 目的 研究食品罐内涂膜的固化工艺对涂膜中双酚A迁移分配系数的影响。方法 在单因素实验的基础上，采用响应面分析法对固化工艺参数进行优化分析，使得双酚A的分配系数最大。结果 三因素对迁移物双酚A分配系数的影响主次顺序为涂膜量＞固化温度＞固化时间，其中固化温度和涂膜量对双酚A迁移的影响极为显著（P<0.0001），且固化温度与固化时间之间，涂膜量与固化时间之间的交互作用极为显著（P <0.0001）。在固化温度为200 ℃，涂膜量为12 g/m2，固化时间为12 min条件下，双酚A迁移的分配系数最大，为5993.02。结论 最佳工艺条件下得到的分配系数与实验值较为接近，说明该响应面得到的工艺参数准确可靠，确保了BPA食品罐的安全性。 |

| The work aims to study the influence of the curing technology on the partition coefficient of bisphenol A in the coating of food can. On the basis of single factor experiments, the response surface method was used to analyze the optimization of the curing technology parameter to achieve the maximum partition coefficient of bisphenol A. The primary and secondary sequence of three factors regarding their influence on the partition coefficient of bisphenol A in the migrant content: coating quantity＞curing temperature＞curing time, in which the influence of curing temperature and coating quantity on the migration of bisphenol A was quite significant (P<0.0001), and the interaction between curing temperature and curing time, and the interaction between coating quantity and curing time were quite significant (P < 0.0001). Under such conditions as curing temperature of 200 ℃, coating quantity of 12 g/m2 and curing time of 12 min, the partition coefficient for migration of bisphenol A was the maximum (5993.02). The partition coefficients and experiment value obtained under the optimal technological condition are quite close, which indicates that the technological parameters obtained for such response surface are accurate and reliable and ensure the safety of BPA food can. |
