The concern for environmental conservation is increasing, and a very important factor to consider is the search for alternatives to the use of plastics in the food packaging industry. A good option is the manufacture of containers of biodegradable materials, such as the so-called biomaterials made of vegetable fibre such as wheat, wood, bamboo or palm leaf pulp. The migration of compounds from food packaging can cause alterations in food safety and acceptability. Therefore, their control through studies of specific migration is definitely important in the food industry. Specific migration has been studied in two types of dishes (wheat pulp and wood) in contact with three liquid simulants (ethanol 10%, acetic acid 3% and ethanol 95%). The analysis of migration extracts have been carried out by solid-phase microextraction coupled to gas chromatography (SPME-GC-MS) in the most suitable working conditions. In addition, those identified compounds considered of interest according to existing legislation have been quantified in order to assess whether exceed or not the migration limits established for some of them. The results obtained show that the quantified compounds are well below the specific migration limits (SML) set by the legislation, thereby showing the safety in use of this type of biodegradable dishes.
人们越来越关注环境保护，在考虑替代食品包装行业中塑料的使用时，有一个非常重要的因素，就是寻找可生物降解材料的容器制造方法，例如以小麦、木材、竹子或棕榈叶浆等植物纤维为原料的所谓生物材料。食品包装中化合物的迁移可能会导致食品安全和可接受性的改变。因此，通过特定迁移的研究来控制它们在食品工业中是非常重要的。在与三种液体模拟物（10%乙醇、3%乙酸和 95%乙醇）接触的两种类型的容器（麦浆和木材）中，对特定迁移进行了研究。在最合适的工作条件下，通过固相微萃取与气相色谱（SPME-GC-MS）对迁移提取物进行了分析。此外，根据现行法规，对那些被认为具有一定意义的已识别化合物进行了定量，以评估其中一些化合物的迁移限量是否超过。所得结果表明，定量化合物远低于法规规定的特定迁移限量（SML），从而表明这种可生物降解容器的使用是安全的。
