Plasticizers in cap-sealing for bottled foods were analyzed. Twenty-three domestic samples and 80 imported samples, a total of 103 samples, were tested. Among them, 93 contained chloride, and 62 contained di(2-ethylhexyl) phthalate (DEHP), diisodecyl phthalate, O-acetyl tributyl citrate, diacetyllauroyl glycerol, di(2-ethylhexyl) adipate, diisononyl phthalate or dicyclohexyl phthalate. Twelve samples with DEHP-containing caps were further tested for plasticizer levels in the foods. Higher DEHP was detected in oily and fluid food specimens. However, the intake of plasticizers calculated based on usual food consumption did not exceed the tolerable daily intake level in any of the cases. A food sample containing the highest level of DEHP was stored under various conditions, and DEHP that migrated from the cap-sealing into the food was determined. Shaking the bottles increased migration of DEHP into foods.
对瓶装食品瓶盖密封中的增塑剂进行了分析。共检测了23个国内样品和80个进口样品，总计103个样品。其中，93个含有氯，62个含有邻苯二甲酸二（2-乙基己基）酯（DEHP）、邻苯二甲酸二异癸酯、柠檬酸O-乙酰基三丁酯、二乙酰基月桂酰甘油、己二酸二（2-乙基己基）酯、邻苯二甲酸二异壬酯或邻苯二甲酸二环己酯。对12个瓶盖含DEHP的样品进一步检测了食品中的增塑剂含量。在油性和流质食品样本中检测到较高含量的DEHP。然而，根据正常食物摄入量计算的增塑剂摄入量在任何情况下均未超过每日可耐受摄入量水平。将一个DEHP含量最高的食品样品在不同条件下储存，并测定了从瓶盖密封迁移到食品中的DEHP含量。摇晃瓶子会增加DEHP向食品中的迁移。
