Is it safe to use recycled aluminum foil facing for baking?

Using recycled aluminum foil facing for baking is generally safe, as long as it meets food-grade standards and is specifically designed for cooking applications. Recycled aluminum foil used in cooking should be free from harmful chemicals and should not release any toxic substances when heated. However, it's crucial to check the packaging to ensure it is labeled as 'oven-safe' and 'food-grade.' Avoid using foil that is not intended for cooking, as it may contain additives or coatings that are not safe at high temperatures. Always follow the manufacturer's guidelines for safe use.
