Is aluminium foil safe for baking? People keep asking similar questions in spite of the fact that they are given positive answers. Aluminium foil for baking is usually hardwood and of multi-roll type packaging. The main components of the foil is 8011 aluminum, the content of the foil is about 50%, the standard of China is defined as “Precision foil”. For aluminium foil for baking, the toxic elements are as follows: 0.01%, cadmium: Unusual 0.01%, arsenic: Unusual 0.01%. The reason is that the most suitable foil is used and its content is set by the national standard.
When you use baking aluminium foil, do not use cooking flavors or lemons, so that acidic substances, such as metal foil and foil, takes out metal deposition that might later be absorbed by human body in contaminated food. Aluminium stimulates stomach and is even believed to cause dementia. People with kidney illness may lack in blood after taking in excessive aluminum. In baking those foods, greens are a good substitute. Food can be wrapped in coconut green leaf, tama rice leaf, or green leaf, which are non-staining and healthy.
How to wrap food in aluminium foil? The aluminium wrapping foil is divided into glossy surface and matte surface. The glossy surface can better absorb external heat and help food to be heated evenly. When you wrap food, the matte surface should be in contact with food, so that the heat is evenly distributed on the surface of the food, shortening the cooking time.
Aluminum foil has the functions of heat preservation, waterproof, sealing and conduction. In addition to helping food to be evenly heated and preventing food from scorching during cooking such as grilling and baking, it can also play a role in cold storage, sealing, heat preservation, and separation of heat sources. It is also indispensable for barbecue in the wild.
In addition, some meat dishes are prone to oil fume or scorch during cooking. Aluminum foil wrap can also solve the problem and avoid the generation of harmful substances. Tin foil is like a mysterious coat, which envelops the nutrients and moisture in the ingredients. The moment when the foil is cut with a knife, the aroma is tangy.
Aluminium wrapping foil paper can withstand high temperatures of about 400 to 600 degrees Celsius, so whether it is boiled, oven or charcoal roasted, there is basically no need to worry too much about the risk of elution of heavy metals.
Is aluminium foil safe to wrap food? Yes. However, the Food and Drug Administration reminded that acidic materials will erode the aluminum wrap foil. It is recommended that the ingredients be cooked and removed before adding acidic substances such as vinegar, lemon, tomato sauce, etc. In addition, if the surface of the aluminum foil is scratched, it is recommended to replace it with new products.
Aluminum foil rolls are light, shiny, strong in reverse ability, good in barrier properties, strong in adaptability to temperature, stable in shape at high or low temperatures, strong in light-shielding, and excellent in fragrance retention. That is why is aluminium foil used to wrap food. However, many people still have doubts about safety of aluminum foil for food wrapping. Is aluminium foil safe to wrap food, anyway?
In the first place, aluminum foil can not be used to wrap some foods containing ingredients that will definitely not work if they react with aluminum, although the surface of the aluminum foil is indeed treated with an oxide film to protect it. Aluminum is an easily oxidizable metal. It has an oxide layer on the surface of the aluminum foil, so that the aluminum ions are tightly fixed by the oxide layer, so that it cannot escape; it further improves the safety of our use of aluminum foil. But keep in mind, try not to touch the aluminum foil or aluminum with strong acid items, because the acid will destroy its oxide layer.
Second, aluminum foil packaging and wrapping has been popular for half a century in many countries in Europe, America, the Middle East and other regions. It has also been widely used in many industries such as domestic aviation, hotels, and West Point cooking. Its worldwide user population is very large. In addition, China, as a major exporter of aluminum foil products, also has world-leading technology in the aluminum foil packaging industry. The products it produces are fully in line with national food packaging safety.
Finally, as emphasized by many scientists, “No food is absolutely safe, and no food is free of any hidden dangers.” At present, it seems that no authoritative institution has experiments to prove that aluminum foil does harm to the human body. The so-called negative effect of aluminum on the human body actually refers to free aluminum ions. For example, the alum used to make rice noodles into rice noodles also becomes aluminum hydroxide. If such aluminum ions are taken in excessively (note that the precondition is excessive dosing , which is not easy for ordinary people to reach), they will cause certain health problems.
So rest assured. Wrap beef and vegetables with aluminum foil as much as you like at a barbecue. Believe in science and practice, don’t scare yourself.
An aluminium foil is used for wrapping food because its performances fully meet the requirements of food packaging, the ultimate goal of which is to extend a food’s shelf life as long as possible. To achieve this, the food must be kept from possible negative materials like light, moisture, micro organism etc.
The aluminum foil are just up to the mustard. As a pure metal product, it’s opaque and nonporous, keeping either light or water gas outside while being used to wrap food. In addition, the aluminium metal is endowed with a natural corrosion resistance. Few of the corrosive materials are capable enough to pierce its defense line to reach the inner side. In this way, bacteria and viruses are kept off.
Aluminum foil itself is sanitary enough, neither emitting nor attracting detrimental elements. The inside of food packaging aluminum foil made to be as smooth as possible, in order to reduce possibility of damages from friction between the foil and wrapped foods.
Because of its advantages above, an aluminium foil roll is used to wrap food items like chocolates, cooked beef, liquid milk, to be baked mini cakes and so on, playing an irreplaceable role in our daily life.
