What is Dimethylpolysiloxane?
Dimethylpolysiloxane is a synthetic, heat-resistant silicone polymer used in various industries. It's a common ingredient in food items, particularly in deep-frying. The compound is also known as polydimethylsiloxane or E900 in Europe. Despite its presence in products like Silly Putty, it has a specific and regulated function in food preparation.
The Role of Dimethylpolysiloxane in Frying Oil
Commercial deep-frying involves heating large amounts of oil to high temperatures. This can cause the oil to bubble and foam excessively, posing safety risks and affecting the frying process. Dimethylpolysiloxane acts as an anti-foaming agent, breaking up air bubbles and preventing oil from foaming over. This ensures a consistent fry and a safer environment for staff.
Is Dimethylpolysiloxane Used at Chick-fil-A?
Yes, Chick-fil-A uses dimethylpolysiloxane in the refined peanut oil it uses for frying many of its menu items. The anti-foaming agent is a component of the oil itself, rather than added separately during cooking. Its use is not unique to Chick-fil-A; many fast-food chains use it for similar purposes. Consumers should always check the most current ingredient lists available from the company, as ingredient changes may occur.
Where can you find this information?
Chick-fil-A provides ingredient and allergen information for its menu items online. By navigating to a specific menu item and expanding the ingredient details, you can find a comprehensive list, including components of their cooking oil. Historical documents from Chick-fil-A have shown dimethylpolysiloxane listed in the preparation of their chicken sandwiches and waffle fries.
Is it harmful?
Dimethylpolysiloxane has been reviewed and approved for use as a food additive by the FDA and the European Food Safety Authority (EFSA). It is considered safe for human consumption in the small amounts used in food products. Studies show that the compound is largely inert and passes through the body without being absorbed. A re-evaluation by the EFSA confirmed no safety concerns at the approved use levels. Some consumers may choose to avoid synthetic additives, which is a personal choice.

Comparison Insights
The use of dimethylpolysiloxane in frying oil is an industry practice, not exclusive to Chick-fil-A. Many restaurants use it to improve their deep-frying process. For consumers focused on additives, this compound is present in fried fast-food products. Alternatives include seeking restaurants with different cooking practices or preparing fried foods at home.
What is the takeaway for consumers?
Consumers concerned about food additives should read ingredient lists to understand what is in their food. Companies like Chick-fil-A provide this information. While regulatory bodies deem the compound safe in small quantities, some people prefer to minimize their consumption of synthetic ingredients. This is a personal choice that involves weighing the regulatory safety assessment against individual comfort levels with processed food components. The inclusion of an anti-foaming agent like dimethylpolysiloxane is standard practice for fried items at many fast-food restaurants, including Chick-fil-A, and is present in very small, FDA-regulated amounts in the cooking oil.
