Parchment is mostly coated with silicone, which some sources claim can be toxic when heated. However, other research shows that silicone-coated parchment paper has non-detect results for organic fluorine, and the silicone coating is considered food-safe and non-toxic
How o Use Parchment Paper Safely (If You Choose To)
Don’t panic! You don’t necessarily need to throw out all your parchment paper. Here’s how to use it more safely:
Always opt for unbleached or food-grade labeled parchment paper. Unbleached versions don’t undergo chlorine processing and are safer for high-heat cooking.
✅Look for PFAS-Free Brands
Some brands have been lab-tested and found to be free of PFAS “forever chemicals”. Look for brands that:
- Use plant-based silicone oil coatings
- Don’t use chlorine in production
- Are transparent about their manufacturing process
✅Respect Temperature Limits
- Stay within the manufacturer’s temperature rating (usually 425-450°F)
- Don’t use parchment paper under the broiler
- For cooking above 400 degrees, consider using foil instead
✅Choose Unbleached Parchment Paper
