Advice 1: Harmful than aluminum cookware and foil for baking

Aluminum cookware is inexpensive, lightweight and durable. Due to the properties of aluminium, the utensils and foil for cooking food heats up quickly. But there is a danger of the penetration of aluminum from cookware into the food.
Harmful than aluminum cookware and foil for baking
Aluminium is contained in permissible amounts in many foods, is present in water and medicines. The human body to digest a small part of aluminium, its excess can easily be excreted without complications.

Aluminum utensils have almost every housewife. In a pot, not stick food, fast heat up liquid. This cookware is lightweight and convenient.
Modern manufacturers of dishes have developed a new production technology. By applying aluminium stainless steel to become more resistant to deformation and chemical effects of aluminum cookware.

The dangers of aluminium

In high concentrations, aluminum is toxic, can cause damage to the nervous system, kidneys, liver, anemia, and growth of tumors.

When cooking with aluminium cookware and foil can enter into a chemical reaction with the products. For example, milk is alkaline, and vegetables – acidic environment. Under the influence of any of these environments, the aluminium gets from utensils to eat, and then in the human body.

The amount of aluminium entering from utensils or foil in the food too small, so to harm a healthy person can not. However, in people with diseased kidneys can cause severe diseases such as Parkinson's and Alzheimer's.

Guidelines for using aluminum cookware and foil

The use of aluminium cookware and foil for baking, is safe for a human, if you observe the following recommendations:
- to cook with a neutral environment: cakes, dairy-free porridge and hot or boiling water;
- after cooking in aluminum cookware or foil is necessary to shift the food in ceramic or glassware;
- not to clean the dishes with abrasive materials, because it damages the protective film.
To restore the oxide (protective) film in aluminium ware damaged when cleaning with abrasive media, you need to dial in a bowl of water and allow to stand for ten minutes, then wipe dry.

The advantages of foil for baking

foil does not absorb fat and sauces when cooking;
- reduces the cooking time, while leaving dishes clean;
the foil pouch is sealed and does not allow the products to absorb odors;
- glossy surface of aluminum foil has anti-bacterial properties that inhibit the development of pathogenic microorganisms;
- due to the opacity of the foil helps to preserve the products all of the vitamins that are destroyed by sun exposure;
- can be used not only at high temperatures, but when freezing the food.

Advice 2: The types and properties of aluminum foil

Aluminum foil is a thin sheet of aluminium, whose thickness is 0.2 mm. It is used for various purposes, for example, to wrap products during construction work.
The types and properties of aluminum foil
Aluminum foil, due to its unique properties, finds a very wide application in various industries: food, pharmaceutical, electrical, aerospace, and construction. It is also frequently used in the home, for example, when the insulation of baths, saunas, because it creates a thermos effect, releasing heat to the outside. And for a reliable coating of the joints and various flexible structures using self-adhesive foil.

Properties of aluminum foil

This material became extremely popular due to a number of valuable properties. First, aluminum foil easily accepts the necessary form, even very complex, because it is very thin, it is easy to deform. It can cover almost any surface. It easily folds, bends, while maintaining its strength. Secondly, aluminium is a corrosion-resistant metal, due to the presence of protective oxide film. That is why foil is used for packaging products. Third, aluminum foil, even the most delicate, completely opaque. And this is very important because when exposed to UV radiation as a food or chemical product may deteriorate. Fourth, aluminum foil, absolutely environmentally friendly material, it can be recycled with 100% completeness.
In addition, a thin aluminum foil is rapidly and completely decomposes in the ground, and thus, does not pollute the environment.

On the surface of the aluminum foil does not occur electrostatic voltage, dust is not attracted (and this is very important in the production of high-precision equipment in some industries). Aluminum foil is resistant to high and to low temperatures, so it is successfully used in the freezing of products and their heat treatment. It is non-toxic, does not change the organoleptic qualities of food products with which it is in contact, protects them from external harmful impacts.

You can list a few useful properties of aluminum foil, but this is enough to ensure its numerous virtues.

Kinds of aluminum foil

To buy the foil should be on the basis of the application. For example, if you want to buy foil for packaging products, it is best to choose the technical. Aluminum foil, depending on the purpose, is divided into three main groups: technical, food and tape. Technical foil has broad applications in the electrical, aircraft and automotive industries. Also it is used in the construction of buildings and separate constructions and as insulating material. This is particularly essential foil for thermal insulation of ventilation systems, water and sewage pipes, floor and roof. At the same time, due to the "thermos effect", don't need a thick layer of material.

In everyday life, as already mentioned, technical aluminum foil is often used when the equipment baths of different designs. It provides quick heating of the premises and retains heat for a long time. Thus, aluminum foil can significantly reduce the cost of heating baths, saunas. Particularly effective on foil, if it is attached directly to the walls and ceiling of a steam room, a mirror inside the room (under the facing boards). In addition, it should be noted that the foil at the same time plays the role of paroizolyator.

Thus, in contrast to materials such as roofing felt, bitumen, etc., when heated to temperatures above 100 ° C aluminum foil does not emit harmful substances. Therefore, its use in the baths and saunas brings a double benefit.
Such foil in areas with a hot climate can be used to protect from sunlight. In the simplest version you just need to stick on the window.

Food foil used for packaging food, tobacco, cosmetics, drugs. It fully preserves their useful properties, taste and flavors. It can be seen in the flasks.

Tape aluminum foil is used in construction, for example, in the manufacture of wall panels.

Also aluminum foil as the surface is reinforced, corrugated, laminated. Reinforced foil used for external insulation of water pipes, corrugated, mainly for the insulation of pipelines and gas pipelines. Laminated aluminum foil, due to the additional layer provides the best protection of the pipes.

For the production of foil leaving much of the investment in the world aluminum. For the record, 75% of the metal necessary for the production of foils for packaging of food, 25% on production needs. Aluminum foil high-temperature resistant, that is why it is used for sealing in the aerospace industry.
