Aluminum foil has a wide range of uses, steaming, baking, boiling can be used, but improper easy to bake coke, and even let the aluminum foil metal dissolve out, and aluminum and increase the risk of dementia doubts, how to use safely?
Aluminum foil can withstand the high temperature of 400-600 degrees, while the boiling temperature is 100 degrees, the oven is about 200 degrees, the charcoal fire is about 300 degrees, generally speaking, there is no need to worry about the problem of heavy metal dissolution.
As for the oven or the barbecue, high-temperature aluminum foil sear, or aluminum foil box after all ingredients into the electric rice cooker, electric pot jumped up on aluminum foil with black, etc, are also worrying whether affect food safety, professor points out that black, sear probably because electric pot in the inland waters has evaporated, jump up aluminum foil with direct contact with the hot plate, high temperature lead to aluminum foil coated carbide black or other substances, it may also be because food oil burnt drop due to high temperature.
To avoid such a situation, as long as pay attention to do not cook for a long time, to avoid water evaporation can be, as to dress food can eat?"Don't worry, just remove the bits that come in contact with the sear and you can still eat the rest.
This kind of situation, carbide not worry whether similar to use charcoal barbecue, generate carcinogenic polycyclic aromatic hydrocarbons in the process of combustion, Professor pointed out that the higher the temperature, polycyclic aromatic hydrocarbons to release a quantity, the more the electric pot heating at 100 degrees, the water is far less than charcoal fire at least 200 degrees temperature, the quantity of released so far less, relatively healthy;Professor believes that pahs are produced because of "incomplete combustion", but there is no burning process in electric pot heating, so users can rest assured that there is no doubt.
