Volatile organic compounds identified in Dutch fresh cheese cups made from polypropylene

This database comprises of two datasets. One dataset of extraction GC-MS analysis and one of headspace GC-MS analysis. In both datasets the same samples are analysed of thermoformed polypropylene cups used to pack 500 grams of fresh cheese in the Netherlands, between July 2024 and March 2025. Samples of these PP cups were taken at the following stages: Stage A: at the producer, directly after thermoforming, Stage B: at the producer after filling the cups with fresh cheese and emptying them, Stage C: retrieved from households, in which the fresh cheese was consumed, the cups were emptied and rinsed with cold water, Stage D: retrieved from the conveyor belt of a Dutch sorting facility of lightweight packaging waste carrying sorted PP rigids, Stage E: the material from stage D washed with cold alkaline water, Stage F: the material from stage D washed with hot alkaline water. Additionally, also the concomitant shrink sleeves and PP lids have been analysed. The datasets list the volatiles that could be identified with GC-MS analysis and their approximated concentration.本数据库包含两类数据集，其一为萃取气相色谱-质谱（GC-MS）分析数据集，其二为顶空气相色谱-质谱（GC-MS）分析数据集。两类数据集均采用2024年7月至2025年3月间荷兰地区用于包装500克鲜奶酪的热成型聚丙烯（PP）杯的同一样本进行分析。该类聚丙烯杯样本的采集阶段如下： 阶段A：生产商处，热成型工序完成后即刻取样； 阶段B：生产商处，向杯体装填鲜奶酪并倾倒空杯后取样； 阶段C：从家庭场景回收，此时鲜奶酪已被食用，杯体被倾倒并以冷水冲洗； 阶段D：从荷兰轻量化包装废弃物分选厂的传送带取样，该传送带运输已完成分选的硬质聚丙烯材料； 阶段E：对阶段D获取的材料采用冷碱性水溶液洗涤； 阶段F：对阶段D获取的材料采用热碱性水溶液洗涤。 此外，研究团队亦对配套的收缩套膜与PP盖进行了分析。 两类数据集列出了经气相色谱-质谱分析可识别的挥发性组分及其近似浓度。
