Background

The metal can has the obvious advantages of good tightness, high internal pressure resistance and suitability for containing carbonated beverages which have little requirements on pressure, air and acid resistance. For fruit and vegetable juice, organic acid is an important component for determining the taste, and can display the special aroma of fruits. The sugar-acid content ratio in the fruit and vegetable juice is an important reason for influencing the taste, but the organic acid has certain corrosivity. In addition, important components in the fruit and vegetable juice, such as enzyme, vitamin C, pigment, and the like, have certain requirements on light and temperature. However, pop cans adopt tinplate three-piece cans and aluminum two-piece cans, and are internally coated with epoxy phenolic type coating (sometimes a layer of vinyl coating is required to be further coated on the epoxy phenolic type inner coating), so that organic acids such as fruit and vegetable juice cannot pose a threat at all, and people pour bottled beer into cups when drinking beer, but a large amount of foam is generated in the process, so that the mood of drinkers is affected, and the stomachs can be expanded if the foam is drunk into the stomachs.
