| 中文摘要: |
| 采用红外光谱技术对PVC食品包装材料进行了鉴定分析，并通过蒸发残渣方法，重点研究了不同条件下PVC中物质的总迁移规律。结果表明，PVC产品中含有较高含量的邻苯(脂肪族)二甲酸酯类增塑剂等非挥发性化学物，极易在高温下迁移到脂类食品模拟液中。其物质总迁移量大小顺序为：95%乙醇≥正己烷＞水≈4%乙酸≈20%乙醇。PVC中物质的总迁移量在高温下是相对较高的，且随迁移时间的延长而增加。 |
| 英文摘要: |
| Food contact polyvinyl chloride (PVC) materials were characterized and analyzed by FTIR. The overall migration of chemicals from PVC under different conditions was studied by evaporation residue method. The results indicated that a high quantity of non-volatile chemicals including plasticizers of phthalate esters or fatty diacid esters existed in the PVC products, which can easily migrate into oil-type food simulates under high temperature; The sequence of migration quantity is as following: 95% ethylalcohol≥hexane＞water≈4% acetic acid≈20% ethyl alcohol; the quantity of migration is relatively large under high temperature; and the migration quantity increased with time extending. |
