Can aluminum pot be used or not?

Aluminum pot is a common cooking utensil, which is widely used in families and restaurants because of its fast heat conduction, convenient carrying and beautiful appearance. However, there are some controversies in aluminum pot, mainly focusing on whether it will have an impact on health. In fact, aluminum is an active metal, which easily reacts with water and oxygen to form alumina.

If the aluminum pot is damaged or used for a long time, the aluminum oxide on the surface may fall off, which will lead to the decrease of thermal conductivity of aluminum pot and even release aluminum ions. Excessive intake of aluminum ions may have a negative impact on health. So it is very important to use aluminum pot correctly. Aluminum pot with good quality should be selected to avoid inferior or damaged aluminum pot. At the same time, try to avoid heating aluminum pot at high temperature for a long time, so as not to accelerate the oxidation process.

Selection method of aluminum can

1. material: aluminum pot made of high-quality aluminum alloy. This material has good thermal conductivity and corrosion resistance, and its material can be judged by observing whether there are traces of "pure aluminum" and "alloy" at the bottom of the pot.

2. Thickness: The thickness of aluminum pot is also an important factor affecting its quality and service life. Generally speaking, the thicker the aluminum pot, the better the quality, but weight and portability should also be considered. It is recommended to choose a thickness of about 2-3 mm.

3. Surface treatment: There are many surface treatment methods in aluminum pot, such as spraying, electroplating and polishing. Among them, the sprayed aluminum pot surface is smooth and beautiful, but it is easy to wear; Electroplated aluminum pot is durable, but the price is high, so you can choose the appropriate surface treatment according to your own needs.
