Both galvanized steel and aluminized steel are commonly used in the construction of toaster oven interiors, but in terms of safety and non-toxicity, aluminized steel is generally considered the better option.
Aluminized steel is a type of steel that has been coated with aluminum-silicon alloy, providing it with enhanced heat resistance and corrosion resistance. It is commonly used in kitchen appliances like toaster ovens due to its ability to withstand high temperatures without releasing toxic fumes. Aluminized steel does not contain harmful coatings like Teflon or other non-stick substances, which can emit potentially hazardous fumes when exposed to high heat.
On the other hand, galvanized steel is coated with a layer of zinc to protect it from rusting. While galvanized steel is durable and corrosion-resistant, it may not be the best option for toaster oven interiors from a health perspective. The zinc coating on galvanized steel can release harmful fumes when exposed to high temperatures, potentially causing a condition known as "metal fume fever," which can lead to flu-like symptoms.
For a non-toxic toaster oven, it's preferable to choose one with an interior made of aluminized steel or other materials that are specifically marketed as safe and non-toxic. When purchasing a toaster oven, you can check the product specifications or contact the manufacturer to inquire about the materials used in the interior construction. It's always essential to prioritize safety, especially when dealing with appliances that involve high temperatures and potential food contact.
