Parchment paper is a kitchen essential many home cooks and professional chefs rely on for its convenience and versatility. It’s known for making baking and cooking tasks easier, with its non-stick and heat-resistant properties. However, there’s more to this humble kitchen tool than meets the eye. Beneath its familiar surface lies a complex story of chemical treatments and potential health concerns that few are aware of.

What if the very parchment paper you trust to keep your baked goods from sticking might also be introducing unwanted chemicals into your food? And are there safer alternatives that can provide the same benefits without the risks?

Understanding Parchment Paper

Parchment paper, commonly known as baking paper, is a cellulose-based paper that has been specially treated to enhance its durability and heat resistance. The primary process that parchment paper undergoes is known as parchmentization. This process involves passing the paper through an acid bath, which dissolves the surface of the fibers, turning them into a gelatinous mass that bonds together, resulting in a dense and heat-resistant paper​​.

After parchmentization, the paper is thoroughly washed to remove any remaining acid and then dried. The result is a tough, impermeable paper that is resistant to water, grease, and heat, making it ideal for various cooking applications​​. [1]

Silicone Coating

Most parchment paper is coated with silicone to further enhance its non-stick properties and heat resistance. The silicone coating allows parchment paper to withstand oven temperatures up to 450°F (232°C) without burning or melting. This coating also makes the paper moisture-proof, ensuring that it does not absorb liquids from the food​.

Unbleached parchment paper retains its natural brown color, while bleached parchment paper undergoes a chemical treatment to remove its natural color, resulting in a white appearance. Both types are widely used in kitchens for their non-stick and heat-resistant properties​​. [2]

Common Uses of Parchment Paper

Parchment paper’s versatility makes it a staple in both home and professional kitchens. Here are some of its most common uses:

  • Lining Baking Sheets and Pans: Parchment paper is often used to line baking sheets and cake pans to prevent sticking and make cleanup easier. This use is particularly beneficial for baking cookies, cakes, and bread​.
  • Cooking En Papillote: A popular technique where food is cooked in a parchment paper pouch. This method traps steam, ensuring that the food is cooked gently and evenly while retaining its moisture and flavor​​.
  • Separating Layers of Food: Parchment paper can be used to separate layers of baked goods or candies, preventing them from sticking together during storage​.
  • Funneling Ingredients: It can also be fashioned into a funnel for transferring dry ingredients, grated cheese, or spices without creating a mess​​.
  • Covering Work Surfaces: Taping parchment paper to a countertop provides a clean, non-stick surface for tasks like rolling out dough or forming meatballs. After use, the paper can be easily disposed of, simplifying cleanup​. [2]

Environmental Considerations

While parchment paper is highly useful, it has some environmental drawbacks. Most parchment paper is not compostable due to the silicone coating, although some brands offer compostable options. The production and disposal of parchment paper can also contribute to environmental waste. As a result, many people are turning to reusable alternatives like silicone baking mats, which offer similar benefits without the waste​​.

Health Concerns Associated with Parchment Paper

While cooking with parchment paper may seem convenient, it’s crucial to be aware of potential health concerns. The primary issues stem from the bleaching process and the silicone coating used in its production.

The Bleaching Dilemma

One significant concern is the bleaching process involved in making parchment paper. Bleached parchment paper may contain dioxin, a toxic chemical released when the paper is heated. Dioxin exposure has been linked to various health issues, including reproductive and developmental diseases. 

Once ingested, dioxin can accumulate in our fatty tissues and remain there for 7 to 11 years, posing long-term health risks. As research indicates, “Dioxin can transfer to our fatty tissues and remain there for 7 to 11 years,” emphasizing the persistence and potential danger of this chemical in our bodies.

The Silicone Coating Problem

Another critical issue with parchment paper is the silicone coating. Silicone cookware, including parchment paper, is made from silicon, carbon, and oxygen, forming a rubber-like substance. Although silicone is generally more heat-resistant than plastic, its safety is still a subject of debate, especially when used for cooking.

When silicone bakeware is heated with oils, it can release chemicals that may pose health risks. Despite being deemed safe by the U.S. Food and Drug Administration (FDA) in 1979, there have been no subsequent FDA studies to assess whether silicone can leach out of cookware and contaminate food. This gap in research raises concerns about the safety of using silicone-coated parchment paper.

Furthermore, research has shown that siloxanes can leach from silicone products such as baby bottle nipples and bakeware. Siloxanes have been linked to potential carcinogenic and endocrine-disrupting effects. A study highlighted, “Silicone gel has been linked to lethal cancer in rats,” which stirs ongoing debates about the overall safety of silicone in kitchen products. [3]
