Discover the Scientific Evidence on PFAS in Parchment Paper, Health Risks, and the Best Alternatives for a Safe Kitchen

By Marco Arezio

Parchment paper is commonly used in cooking for its non-stick properties and heat resistance. However, recent scientific studies have raised concerns about the presence of per- and polyfluoroalkyl substances (PFAS) in certain types of parchment paper.

PFAS in Parchment Paper: Scientific Evidence

A study published in Foods in 2024 analyzed the presence of PFAS in single-use materials that come into contact with food, including parchment paper. The results revealed that some samples of parchment paper contained PFAS, with these substances migrating into food during cooking.

Specifically, the presence of perfluorooctanoic acid (PFOA), classified as carcinogenic to humans by the International Agency for Research on Cancer (IARC), was detected.

Another study by Fosan examined the migration of PFAS and organophosphate esters (OPEs) from parchment paper and aluminum foil into food. The findings showed that parchment paper released higher amounts of these substances compared to aluminum foil, with migration levels potentially contributing to human dietary exposure.

Health Risks Associated with PFAS

PFAS are known for their persistence in the environment and their ability to accumulate in living organisms. Long-term exposure to these substances has been linked to various health issues, including:

- Immune system dysfunctions

- Altered thyroid function

- Reproductive problems

- Increased risk of certain types of cancer

Their presence in food contact materials, such as parchment paper, thus represents a potential source of exposure for consumers.

Regulations and Policies

In Europe, the European Chemicals Agency (ECHA) has recognized the need to regulate PFAS usage due to their harmful effects on human health and the environment.

However, specific regulations regarding the presence of PFAS in food contact materials vary across countries.

Tips for Consumers

To reduce exposure to PFAS through the use of parchment paper, it is recommended to:

Check labels: Choose products that explicitly state the absence of PFAS.

Avoid high temperatures: Do not exceed the maximum temperatures indicated by the manufacturer to prevent material degradation and possible chemical migration into food.

Consider alternatives: Use reusable food-grade silicone mats or other safe materials for cooking.

Conclusion

Scientific evidence indicates that some parchment papers may contain PFAS, posing potential health risks. It is therefore essential for consumers to stay informed and careful when choosing products, reading labels attentively and opting for safer alternatives.
