Microwave Ovens Cannot Use "Tin Foil", And It Is Better to Wrap Food with Matte Surface

    When using an oven, the most indispensable thing is "tin foil", which can be laid on the baking tray to prevent the meat juice from overflowing and reduce the cleaning burden; It can also wrap around food, doubling its heat and evenly spreading the heat to the surface. And the 'tin foil' we use now is mostly made of aluminum foil.
    Aluminum foil cannot be heated in the microwave oven. Although "tin foil" is as soft as paper, it is essentially still metal. Microwaves cannot penetrate metals, so food will not be heated; In addition, metals can reflect microwaves, damage microwave tubes, generate electrical sparks, and even cause fires and explosions. Oven uses the heat radiation of heating tubes for heating, which belongs to the traditional heating method and is suitable for using aluminum foil. Aluminum foil can also be used in microwave ovens with barbecue function, but the prerequisite must be barbecue mode, and microwave heating must not be used.
   When using aluminum foil, should we wrap the food with a matte or glossy surface? Because aluminum foil is very thin, manufacturers usually use two layers of simultaneous compression to prevent breakage. During the process of mutual contact between two layers of aluminum foil, friction will inevitably occur, resulting in the formation of a matte surface; And if the other side comes into direct contact with the smooth machine, it will form a smooth surface. The time difference for heating food on both sides is not significant. The reflectivity of the matte surface is 80%, and the reflectivity of the glossy surface is 88%, both of which can be used. It is recommended to use a matte surface in direct contact with food, as a smooth surface is more likely to stick to food.
