Non-toxic, silicone cake molds are produced using food-grade silicone materials. Silica gel is an amorphous substance, and its chemical formula is mSiO₂ · nH₂O. It is insoluble in water and any solvents, non-toxic and odorless, chemically stable, and does not react with any substance except strong alkali and hydrofluoric acid. Silicone is also widely used in the production of maternity and baby products, medical products, artificial limbs, etc.
The safety of silicone cake molds. When purchasing molds, you must see whether the molds have undergone toxic testing, whether they are high-quality food-grade silicone materials, and whether they have passed international European standard certification. Secondly, it can be distinguished by appearance and smell. From the appearance, the higher the transparency, the higher the food grade. The surface of the food-grade silicone is smooth and powder-free, and it is not easily deformed, discolored, or warped. The simplest identification method of industrial silicone is to have a pungent smell of gasoline, and food-grade silicone does not have any odor.
Silicone is resistant to high and low temperatures from -40 ° C to 230 ° C, so baking cakes with silicone molds is non-toxic.
