What is Tin Foil
Tin foil, also known as aluminum foil, is a metal foil made of aluminum through multiple rolling.
The thickness is usually less than 0.02mm and is mostly silver-white. It is mainly used for food packaging, cooking and protection.
The main component of tin foil is aluminum, which is processed by aluminum blocks on aluminum foil rolling mills.
Tin foil is widely applied in various occasions, including:
Food packaging: used to package food, medicine, cosmetics and other chemicals to protect and preserve these items
Cooking: used in high-temperature heating environments such as ovens and steamers, such as roasting chicken and fish, to improve heat conduction and maintain the original flavor and taste of food
Protection: used to wrap and protect items to prevent moisture, contamination or damage
Tin foil is safe to put in the oven. Tin foil is a high-temperature resistant metal paper, usually made of aluminum, with a melting point of up to 660°C,
while the maximum temperature of an ordinary oven usually does not exceed 220°C, so tin foil is safe to use in the oven.
How to use tin foil in the oven and precautions
Avoid contact with open flames: When using tin foil, avoid direct contact with open flames to prevent the foil from melting or burning.
Avoid using strong acid seasonings: If strong acid seasonings are used in food, it is best not to use tin foil to wrap it, so as to avoid aluminum dissolving in the tin foil and affecting the safety of the food.
Use tin foil correctly: It is usually recommended to use the shiny side to contact the food and the photosensitive side outward, so that it can better absorb heat, heat the food evenly, and prevent burning.
Benefits of putting tin foil wrapped food in the oven
1. Fast heat transfer
Tin foil has a very good heat conduction effect. Wrapping food in tinfoil and putting it in the oven for cooking can transfer the temperature in the oven to the inside of the food.
It can not only save cooking time, but also ensure that the food is cooked to the same degree of doneness inside and outside. It is a good way to bake foods such as whole chickens or large steaks.
2. Prevent burning
Tin foil itself is waterproof and heat-insulating. Wrapping food with it and baking it in the oven can prevent the food from being burned, prevent the oil from splashing and dirtying the box when the food is baked, and prevent the food from losing moisture during the baking process, preserving the fresh taste of the food.
3. Anti-sticking
In addition to being used to wrap food and put it in the oven, tinfoil can also be spread directly on a baking tray or grill, and the food can be placed on the tinfoil.
This can prevent the baking tray from getting dirty or oily due to food sticking to it, making it difficult to clean.
In particular, when baking some food that has been brushed with seasonings and sauces, the seasonings can easily burn and stick to the baking tray at high temperatures, making it difficult to clean.
Is Tin Foil Toxic
Whether tin foil is toxic or harmful to the human body usually depends on how it is used and the degree of contact. Tin foil itself contains metallic tin, which may cause certain health risks if ingested by the human body.
Tin foil may release trace amounts of metal elements such as tin and aluminum during cooking. Long-term and large-scale intake of these metal elements may cause cumulative damage to the human body, especially adverse effects on the nervous system and kidney function.
For example, some studies have shown that excessive intake of aluminum may be associated with an increased risk of Alzheimer's disease. When cooking, avoid using tin foil to wrap acidic or alkaline foods, as this may accelerate the release of metals.
Common cooking materials such as lemons, tomatoes and chocolate may react with tin foil.
When using tin foil, try to minimize direct contact with food, especially acidic or high-fat foods, to reduce the risk of metal release. At the same time, you should eat a reasonable diet and avoid long-term and large intake of foods that may contain metal elements.
