I. Reasons
Excessive accumulation of (1) aluminum in human body can damage human brain cells and cause memory loss. This poisoning process is not easy to detect and takes a long time. The melting point of aluminum is 660 degrees Celsius, so the risk of precipitation during barbecue is relatively small.
(2) Aluminum foil can not only transfer heat, but also prevent the meat from directly contacting the flame, which is equivalent to wearing a layer of "fireproof clothing" to reduce the chance of being burned. In addition, wrapping food with aluminum foil can prevent water loss, especially meat, which tastes fresh and tender after cooking, and can also prevent baked food from sticking to the baking tray.
I. Matters needing attention
(1) Tin foil paper is a metallic substance, which is not toxic in itself. However, it is worth noting that in the past, food was baked in tin foil or aluminum foil, but experts suggested that if food was baked in tin foil or aluminum foil, no sauce should be added, because acidic substances in seasoning may dissolve tin and aluminum in tin foil and aluminum foil, which may cause tin and aluminum poisoning after eating.
(2) In the baking process, constantly apply lemon juice to the meat according to the texture, and it is best to drop a few drops of lemon juice before eating.
Need to be reminded that if the meat is wrapped in tin foil for barbecue, don't pour lemon juice on the meat, because tin foil is a metal substance, which will produce a certain chemical reaction after contact with acidic substances at high temperature, resulting in harmful carcinogens.
(3) When food is processed by methods such as frying, baking and smoking. , it is easy to produce benzopyrene and dioxin.
Carcinogens such as Britain should not be eaten more. Whether baking with tin foil can isolate carcinogens has not been confirmed yet. However, whether it has the function of isolating carcinogens or not, tin foil is easy to cause heavy metal pollution.
