Calphalon Cookware: Ptfe And Pfoa Free?

Calphalon's non-stick cookware has previously been made with polytetrafluoroethylene (PTFE), a synthetic resin with a high heat tolerance. PTFE was historically manufactured with perfluorooctanoic acid (PFOA), a chemical linked to various illnesses and health issues. However, since 2013, PFOA has been removed from the PTFE manufacturing process, and Calphalon now uses PFOA-free PTFE in its non-stick coatings. Calphalon also offers PTFE- and PFOA-free ceramic cookware, which is safe to use up to temperatures of 450°F.

Calphalon's PTFE-free alternatives

Ceramic Non-Stick

Ceramic non-stick pans are believed to be a safer alternative to PTFE. They are made with sol-gel, a derivative of sand. While they don't last as long or release food as efficiently as PTFE, they are still a good option.

Cast Iron

Cast iron is a durable and long-lasting option. It retains heat well, allowing for even cooking. However, it requires proper seasoning to maintain its non-stick properties. Additionally, acidic foods will erase its non-stick qualities.

Enameled Cast Iron

Enameled cast iron offers the benefits of cast iron with the added advantage of being non-reactive and stick-resistant.

Carbon Steel

Carbon steel is similar to cast iron but is less prone to rusting. It requires regular seasoning, but when seasoned, it will deliver excellent non-stick results.

Stainless Steel

Stainless steel pans are PTFE-free and have natural non-stick properties. They are extremely durable, heat evenly, and are easy to clean. They may require additional oil or butter to prevent food from sticking.

Other Alternatives

Other alternatives to PTFE-coated cookware include traditional options such as aluminium and carbon steel, as well as newer options like nonstick ceramic cookware.

PTFE's negative attention

Calphalon's non-stick cookware is made from polytetrafluoroethylene (PTFE), a synthetic fluoropolymer of tetrafluoroethylene. PTFE is perhaps best known for its non-stick properties, but it has attracted a lot of negative attention over the years.

PTFE was originally discovered by DuPont in 1938 and was used to coat valves and seals in the Manhattan Project. It was first used in non-stick cookware in 1954, and since then, hundreds of manufacturers have offered non-stick cookware to consumers. However, PTFE has come under scrutiny for its potential health and environmental risks.

For decades, PTFE was made with perfluorooctanoic acid (PFOA), which has been linked to various illnesses and health issues. PFOA is a persistent organic pollutant that has been detected in the blood of people living or working near factories that use this chemical. It has also been found in industrial waste, house dust, water, food, and PTFE cookware. Due to legal actions and health concerns, PFOA has been discontinued in the manufacturing process of PTFE since 2013.

Despite the removal of PFOA, PTFE still has the potential to release toxic fumes when heated above 536°F. These fumes can cause flu-like symptoms in humans, and prolonged exposure can lead to more severe reactions such as lung damage. Additionally, the chemicals used in PTFE production, such as GenX, have been shown to cause similar health problems as PFOA.

While Calphalon's PTFE cookware is marketed as safe for consumers, it is essential to follow the recommended precautions, such as avoiding overheating and using metal utensils that could scratch the surface.

PTFE's history with PFOA

PTFE, or polytetrafluoroethylene, is a synthetic fluoropolymer of tetrafluoroethylene. Commonly known as Teflon, it was accidentally discovered in 1938 by Roy J. Plunkett, who was working for DuPont at the time. As Plunkett attempted to make a new chlorofluorocarbon refrigerant, he noticed that the tetrafluoroethylene gas in its pressure bottle had stopped flowing before the bottle was empty. Upon further investigation, he found the bottle's interior coated with a waxy white material that was oddly slippery. This substance was polymerized perfluoroethylene, with the iron from the inside of the container having acted as a catalyst at high pressure.

DuPont trademarked the substance as Teflon in 1945 and began producing it in large quantities in 1948. An early use of the chemical was in the Manhattan Project, where it was used as a material to coat valves and seals in the pipes holding highly reactive uranium hexafluoride.

In the 1950s, PTFE began to be used as a non-stick coating for pans and other cookware. It was also used in various other products, including waterproof apparel, personal care products, and industrial coatings.

For decades, PTFE was produced using PFOA (perfluorooctanoic acid), a chemical that has been linked to negative health effects. However, due to growing concerns over the health and environmental impact of PFOA, manufacturers began phasing out its use in PTFE production. Since 2013, PTFE-coated cookware has been PFOA-free.

PTFE's health risks

PTFE is considered safe for everyday home cooking, as long as the temperature does not exceed 500°F (260°C). At temperatures above 300°C, PTFE coatings may begin to break down and release fumes that are harmful to humans and fatal to birds. These fumes can cause a condition called polymer fume fever, or "Teflon flu", which presents as flu-like symptoms that usually appear within 4 to 10 hours of exposure and resolve within 48 hours. Prolonged exposure to these fumes can lead to more severe reactions, such as lung damage.

PTFE itself is not considered a significant health risk, but there have been concerns about its potential to release toxic gases and chemicals at normal cooking temperatures. However, the toxicity of PTFE is not well understood, and more research is needed to determine the potential risks to human health.

One of the main concerns with PTFE in the past was its association with perfluorooctanoic acid (PFOA), which is a risk factor for various health conditions, including chronic kidney disease, liver disease, thyroid disorders, testicular cancer, infertility, and low birth weight. PFOA was previously used in the manufacturing process of PTFE but has since been removed due to health and environmental concerns. All PTFE products have been PFOA-free since 2013.

In summary, while PTFE is generally considered safe for cooking, it is important to avoid overheating PTFE-coated cookware to prevent the release of toxic fumes. Additionally, while PFOA is no longer present in PTFE products, there may be other chemicals or ingredients that could pose potential health risks, and further research is needed to fully understand their impact on human health.

PTFE's safe usage

Calphalon's non-stick cookware is made with PTFE, a synthetic resin with a high heat tolerance and a slick surface. PTFE is also known by the trademarked name Teflon.

PTFE was previously manufactured with a chemical known as PFOA, which was linked to various illnesses and health issues. However, since 2013, PFOA has been removed from the PTFE manufacturing process, and Calphalon's PTFE is PFOA-free. The American Cancer Society has stated that there are no proven risks to humans from cooking with non-stick pans, such as those made by Calphalon.

However, it is important to note that PTFE should not be overheated. When PTFE reaches temperatures of 536°F (279°C), it starts to release fumes that are harmful to humans and dangerous to birds. These fumes can cause polymer fume fever, or "Teflon flu," which presents as flu-like symptoms that typically resolve within 48 hours. Prolonged exposure to these fumes can lead to more severe reactions, such as lung damage.

To safely use PTFE-coated cookware, such as Calphalon's non-stick pans, it is recommended to follow these guidelines:

• Avoid exceeding the recommended temperature range of 400-500°F (204-260°C).
• Do not use PTFE-coated cookware on high heat settings, such as those required for searing meat. Instead, stick to low to medium heat.
• Avoid using PTFE-coated cookware in the broiler.
• Ensure your kitchen is well-ventilated during cooking by using exhaust fans or opening windows.
• Do not use metal utensils that can scratch the PTFE coating. Scratches can lead to the release of PTFE fumes at lower temperatures.
• Replace PTFE-coated cookware if you notice any scratches, flaking, or other signs of wear and tear.
• Always hand wash PTFE-coated cookware with non-abrasive sponges or cloths and avoid using dishwasher detergent, as this can wear down the coating over time.
• Do not use PTFE-coated cookware for broiling or over a campfire, as the temperature cannot be controlled.

By following these precautions, you can safely use PTFE-coated cookware, such as Calphalon's non-stick pans, without any health risks.
