Does it have to be wrapped in tin foil to bake things in the oven?

Generally speaking, people like to bake meat, sweet potatoes and other foods that have been baked for a long time with tin foil, mainly to prevent burning, but also to avoid oil stains and other stains that make the oven difficult to clean. Whether to use tin foil paper can be decided according to your own preferences and eating habits.

Extended data:

Use tin foil carefully when baking food.

Tin foil paper and aluminum foil paper are mostly used to wrap barbecue ingredients to prevent meat from burning. The main component of tin foil is lead-tin alloy. The lead content in tin foil is as high as 50%, and toxic lead white and lead hydroxide are also generated on the surface. Yellow Huang Dan (lead monoxide) produced during incineration is also a toxic compound.

These toxic particles float in the air with hot air, are inhaled into the respiratory tract by people around them, and are deposited in the lungs, which easily leads to chronic lead poisoning, which can cause depression, anemia, kidney disease, infertility, abortion and other symptoms. In addition, in the process of using tin foil or aluminum foil, if you just wrap the ingredients with them and put them in the oven for barbecue, it will hardly harm your health.

However, if sauce or lemon is added to food, the acidic substances in it will precipitate tin and aluminum from tin foil paper or aluminum foil paper, which will be absorbed by human body when mixed with food, thus causing tin and aluminum poisoning to consumers. Tin can irritate the stomach, and aluminum can cause Alzheimer's disease. If kidney patients consume too much aluminum, anemia will occur.
