为探索食品调料中微塑料的特征,本文对来自不同地区、采用不同原料加工的34个调料样品中微塑料的丰度、大小、形状和材质等进行研究。结果表明,供试调料样品中,微塑料的平均丰度为1.75个/100 g;微塑料的粒径均小于5 mm;纤维状材质的微塑料占比较大,其次是薄膜微塑料和颗粒状微塑料,占比分别为56%、35%和9%;微塑料的材质分别为人造纤维、聚乙烯、聚丙烯、聚酯纤维和烯烃类纤维。研究为食品调料品质提高和食品安全保障提供参考。
In order to explore the characteristics of microplastics in food seasonings, the abundance, size, shape, and material of microplastics in 34 seasonings processed from different regions and raw materials were investigated. The results showed that the average abundance of microplastics in the tested seasoning samples was 1.75 per 100 g. The particle size of microplastics in the seasoning samples was all less than 5 mm. Fibrous microplastics accounted for a large proportion of microplastics, followed by thin film microplastics and granular microplastics, accounting for 56%, 35%, and 9%, respectively. The materials of microplastics in seasonings were artificial fibers, polyethylene, polypropylene, polyester fibers, and olefin fibers. Research provided a reference for improving the quality of food seasonings and ensuring food safety.
