摘要
Abstract
A series of polypropylene(PP)films containing antioxidant 1010 and antioxidant 627A were separately pre-pared.The antioxidant content of the films was determined by microwave extraction and liquid chromatography.Eight different food simulants were employed to simulate water-based foods(pH>4.5),acidic foods(pH≤4.5),alcoholic foods,and fatty foods.The migration of antioxidants to food simulants was investigated at three different temperatures and five different times.The results indicated that the migration levels of the two antioxidants to water,3 wt%acetic ac-id,and 10 vt%ethanol as three simulated substances were below the detection limit.When the simulated substance was n-hexane,both antioxidants could reach the maximum migration amount quickly.Antioxidant 1010 has a strong interac-tion with PP molecules to bind well with the matrix.Its overall migration was relatively small did not migrate even in al-coholic foods below 40℃.Moreover,its migration in the high-concentration alcoholic and fatty foods was significantly lower than that of antioxidant 627A.关键词
