In developed countries in Europe and the United States, aluminum foil for baking have been widely used like egg tart trays, dessert trays, bread paper, cake trays, etc. According to the statistics of relevant foreign institutions, in developed countries in Europe and the United States, the total amount of aluminum foil products per capita is as high as 70 kg per year.
Cooking aluminum foil are mostly used for catering, bakery food packaging, utensils, etc. Because they are very convenient and mostly "disposable", they are widely used. Aluminum foil is a healthy and safe material resistant to high and low temperatures. It will not cause any harm to the human body under high temperature conditions. Many big brands or chain stores will use this kind of aluminum foil bread tray.
Aluminum foil is usually very thin, with a thickness of no more than 0.2 mm, but it has strong thermal conductivity and high temperature resistance. When baking cakes or other foods, cover them with a layer of aluminum foil to prevent the surface of the finished product from being too dark or burnt.
Use it to wrap processed vegetables and meat and put them in the oven to make the food more tender and juicy. Not only that, aluminum foil can also be used as a container for holding food, and it can be shaped into any shape to make a mold.
Aluminum foil is one of the very practical cooking tools in the kitchen. It can not only gather heat, but also allow food to absorb heat more quickly, greatly shortening the time required for cooking, and at the same time keeping food warm. But when we use aluminum foil to bake, we need to pay attention to the following three aspects:
1. Aluminum foil has two different sides. One side is very glossy and the other side is matte. Many people think that both sides are the same when using aluminum foil for the first time, but this is not the case. When using aluminum foil pay attention that the matte side is used to contact food, that is to say, the matte side should face inward. If you use it upside down and use the bright side to wrap the food, it is easy for the food to stick to the aluminum foil.
2. Try to avoid contact with seasonings or foods with strong acidity and alkalinity to avoid chemical reactions. Those seasonings like vinegar, lemon, baking soda, etc., are easy to have a chemical reaction with the aluminum.
3. Food wrap foil cannot be used in a microwave oven.
