Abstract The adsorption efficiency of different packaging materials for benzo(α)pyrene in meat simulants, namely aqueous ethanol and sunflower oil was investigated. The results showed that low-density polyethylene showed a good adsorption capacity for benzo(α)pyrene, and the residual rate of benzo(α)pyrene in 10% of the ethanol water solution was lower than in sunflower oil, and the residual rate of benzo(α)pyrene in 10% ethanol water solution was 61.25% after 5 d adsorption, which was lower than in sunflower oil. In contrast, polypropylene showed no significant adsorption capacity for benzo(α)pyrene. Both packaging materials were used to package Hunan bacon. After 5 days, the adsorption rate of low-density polyethylene for benzo(α)pyrene reached 43.14%, while that of polypropylene was only 4.65%. Therefore, low-density polyethylene can be used as packaging material for meat products to reduce the content of benzo(α)pyrene in meat products.
