Metal cans are not harmful to human health

Now we all use metal cans to eat and drink. Metal cans are what we often call pop cans. Their lids and bodies are produced separately and then assembled together. When used in many packaging applications, strong internal pressure will make up for the rigidity of thin can walls. However, the high gas resistance, light shielding and sealing of metal cans will keep the quality of the food in the cans stable. What other advantages do they have? Let's take a look at them together

This kind of metal can has obvious advantages. Its airtightness is very good, and it can resist high internal pressure. It is very suitable for loading carbonated drinks, which only require a little pressure, air and acid resistance For fruit and vegetable juice, organic acid is an important component that determines its taste. It can show the unique aroma of fruit The ratio of sugar to acid content in fruit and vegetable juice is an important reason for affecting the taste, but organic acids have certain corrosivity. In addition, the important components in fruit and vegetable juice, such as enzymes, vitamin C, pigments, have certain requirements for light and temperature However, metal cans are made of tinplate three piece cans and aluminum two piece cans, and are also internally coated with epoxy phenolic coating (sometimes a layer of vinyl coating is also required on the epoxy phenolic internal coating). In this way, organic acids in fruit and vegetable juice are not a threat at all
