The use of plastics in the manufacturing of food products is of concern as microplastics (MPs, 1 µm to 5 mm) find their way into food which poses risks to human health. This study is the first to report detection of MPs in selected staple food products in the Philippines, specifically sea salt, white and brown sugar, fish sauce, and rice. Raman microspectroscopy was used to identify the MPs and pigment additives. The mean MP concentration was 471 MPs kg with 71% identified as polyvinyl chloride (PVC) for salt, 20 MPs kg with 67% polyethylene terephthalate (PET) for white sugar, 67 MPs kg with 77% polypropylene (PP) for brown sugar, 3 MPs L for fish sauce, and 5 MPs kg with 100% PET for cooked rice. For sea salt, the highest MP contamination found was PVC that is likely from the processing of this product. This implies the need for careful use of PVC materials in their manufacture. For sugar, rice, and fish sauce, the likely contamination is from plastic packaging. The present findings provide estimation of human consumption of MPs from food items and insights on the use of plastic materials in the manufacturing processes.

食品制造中塑料的使用令人担忧，因为微塑料（MPs，1微米至5毫米）进入食品中，对人类健康构成风险。本研究首次报告了在菲律宾选定的主食产品中检测到微塑料，具体包括海盐、白糖和红糖、鱼露及大米。拉曼光谱显微镜用于识别微塑料和色素添加剂。微塑料的平均浓度为：海盐每千克471个，其中71%被鉴定为聚氯乙烯（PVC）；白糖每千克20个，其中67%为聚对苯二甲酸乙二酯（PET）；红糖每千克67个，其中77%为聚丙烯（PP）；鱼露每升3个；煮熟的大米每千克5个，其中100%为PET。对于海盐，发现的最高微塑料污染物是PVC，可能来自该产品加工过程。这意味着在其制造过程中需要谨慎使用PVC材料。对于糖、大米和鱼露，可能的污染物来自塑料包装。本研究结果提供了食品中微塑料的人类摄入量估计，以及对制造过程中塑料材料使用情况的见解。
