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.
