摘 要:建立乙醇水溶液和葵花籽油模拟物的肉制品模拟物模型,研究低密度聚乙烯(low density polyethylene,LDPE)和聚丙烯(polypropylene,PP)2 种包装材料对模拟物中苯并(α)芘的吸附效果。结果表明:LDPE对肉制品模拟物中的苯并(α)芘具有良好的吸附效果,吸附5 d后,乙醇水溶液模拟物中苯并(α)芘的残留率仅为61.25%,且乙醇水溶液模拟物中苯并(α)芘的残留量低于葵花籽油模拟物;PP对模拟物中的苯并(α)芘无显著吸附效果。用2 种包装材料包装湖南腊肉5 d后,LDPE对腊肉中苯并(α)芘的吸附率达43.14%,而PP仅为4.65%。因此,LDPE可以作为肉制品包装材料,降低产品中苯并(α)芘的含量。

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.

煙熏肉制品因其独特的风味和色泽受到消费者的喜爱,同时具有良好的保藏性能和较长的货架期。但是在肉制品烟熏过程中,由木屑的不完全燃烧形成的苯并(α)芘等多环芳烃类污染物会附着在肉制品表面,对消费者的身体健康造成潜在危害[1-5]。

苯并(α)芘是一种活性很强的致癌物,同时具有致畸和致突变作用[6-12]。苯并(α)芘具有很强的亲脂性,很容易在脂肪含量较高的产品中富集,因此必须严格控制苯并(α)芘的摄入。我国在最新的国家标准

GB 2762—2017《食品安全国家标准 食品中污染物限量》[13]

中明确规定,肉制品中苯并(α)芘的含量不应超过
