Silicone baking trays can be manufactured to any shape. Everything from square-shaped and round muffin trays to lasagna trays can be constructed out of silicone. Round, square and rectangular cake and bread pans of all sizes are available featuring silicone construction. Silicone is flexible, unlike baking trays made of metals such as aluminum and cast iron. You can fold or roll up a silicone baking pan for easy storage. Being able to bend a silicone baking pan can make it easier to remove baked goods from the pan. Silicone baking trays retain their original manufactured shape even after being stored rolled up or flexed for long periods.
Silicone provides a relatively non-absorbent, corrosion-resistant surface. Silicone baking pans offer a non-stick surface, which makes retrieving baked goods cleaner and easier. Unlike many other types of baking pans, silicone baking pans don't stain. Silicone baking bans also offer the advantage of not readily absorbing odors from the food cooked or stored on them.
Silicone baking pans cool relatively quickly after removal from a heat source. Most are heat-resistant to temperatures exceeding 500 degrees F. They're safe for use in the oven and the microwave. Silicone baking trays are also engineered to withstand temperatures well below zero degrees F. You can take them from the oven and place them immediately in the freezer without causing damage. This type of baking tray efficiently and evenly transfers heat to whatever food is in the pan. Food made in silicone baking trays tends to bake evenly, leaving no burnt surfaces.
Manufacturers make their silicone baking trays from food-grade silicone, which is approved for use by the FDA in food preparation. FDA-approved food-grade silicone is a bacteria-resistant material. Some manufacturers produce silicone baking trays that feature a textured surface to allow for better gripping. Silicone baking trays don't dent, break, fade or flake over time. They're dishwasher safe and can be turned inside-out to allow for easy cleaning.
