| 中文摘要: |
| 从油茶籽油生产的原料、工艺、设备、产品包装、储存等环节入手，研究了油茶籽油中邻苯二甲酸酯来源及防范措施。结果表明：茶籽原果本身含有极微量的邻苯二甲酸酯，但不是油茶籽油邻苯二甲酸酯污染主要来源；油茶籽油加工环节使用的加工助剂均未检出邻苯二甲酸酯，不是油茶籽油邻苯二甲酸酯的污染来源；油茶籽油中邻苯二甲酸酯主要来源于生产过程中接触的塑料制品，油样温度越高，或油样与含邻苯二甲酸酯的塑料制品接触时间越长，塑料制品中邻苯二甲酸酯向油样的迁移量会增加；对于受到邻苯二甲酸酯污染的油茶籽油可以采用脱臭工艺将其去除，从而有效解决邻苯二甲酸酯污染风险。 |
| 英文摘要: |
| The source and preventive measures of phthalic acid esters (PAEs) in oil-tea camellia seed oil were studied and discussed from the aspects of raw materials (oil-tea camellia seed), processing technology, equipment, packaging and storage of oil-tea camellia seed oil. The results showed that oil-tea camellia seed itself contained a very small amount of PAEs, but it was not enough to risk the pollution of PAEs in oil-tea camellia seed oil. The processing aids used in the oil-tea camellia seed oil processing did not detected PAEs, so processing aids were not the pollution source of PAEs in oil-tea camellia seed oil. PAEs in oil-tea camellia seed oil were mainly derived from the plastic products contacted in the process of production. The higher the oil sample temperature was, or the longer the contact time between the oil sample and the plastic products was, the migration of PAEs to the oil sample increased. The PAEs in polluted oil-tea camellia seed oil could be removed by deodorization, which could effectively solve the pollution risk of PAEs. |
