HDPE膜中抗氧化剂1076于不同浓度乙醇中的迁移研究

Study on the Migration of Irganox 1076 from HDPE into Ethanol

研究了HDPE膜中抗氧化剂1076向不同浓度乙醇迁移的规律,结果表明:随着乙醇浓度的增加,1076的迁移量也随之增加;对于同一浓度的乙醇,随着温度的提高,1076的迁移量也随之增加。含有1076的HDPE薄膜可用于包装低浓度酒精类的食品,应避免包裹高浓度酒精类食品和高脂肪类食品,以免引起抗氧化剂高迁移问题,同时应避免高温加热等加工。本文研究得到的HDPE膜中抗氧化剂1076的迁出量与乙醇浓度、温度的关系曲线,具有重要的工程应用价值。

The migration of Irganox 1076 from high density polyethylene（ HDPE）film into ethanol-water simulants under different temperature was studied. The results indicated that migrants of 1076 increases as the concentration of ethanol increases, also as the temperature goes up. It can use HDPE film with Irganox 1076 to pack the low-proof alcoholic food. But for food safety, it should be avoid packaging the high concentration alcoholic food and the high fatty food. Meanwhile make sure to avoid high temperature treatment.
