| 摘要: |
| 制备了载银沸石抗菌牛皮纸，运用原子吸收光谱研究了40 ℃下抗菌剂在蒸馏水、4%(体积分数)乙酸、65%乙醇、正己烷和橄榄油中的迁移情况。结果表明：抗菌剂添加量为0.5%的抗菌牛皮纸中含有载银沸石的初始质量浓度为2.85 mg/L。当不同食品模拟物在迁移时间分别为2，24，96，240，960 h时，没添加载银沸石的牛皮纸浸泡的食品模拟液中均未检测到载银沸石，而添加量为0.5%的抗菌牛皮纸在蒸馏水、4%乙酸和65%乙醇中均有迁移，且迁移量大小为：65%乙醇>4%乙酸>蒸馏水，但正己烷和橄榄油中未检测到抗菌剂。 |

| Abstract: |
| The antibacterial kraft paper with silver-loaded zeolite was prepared. The migration of antibacterial agent at 40 ℃ in distilled water, 4%(V/V) acetic acid, 65% ethanol, Olive oil, and N-hexane were studied by using AAS. Results showed that the initial concentration of silver-loaded zeolite in antibacterial kraft paper with the addition of 0.5% antibacterial agent is 2.85 mg/L; while the time of migration is 2 h, 24 h, 96 h, 240 h, and 960 h respectively, there are no antibacterial agent in kraft paper with 0.0% antibacterial agent; however, migration of antibacterial paper with 0.5% silver-loaded zeolite in distilled water, 4% acetic acid, 65% ethanol are detected, and the migration amount are 65% ethanol>4% acetic acid>distilled water; moreover, antibacterial agent is hardly found in Olive oil and N-hexane. |
