In recent years, polyethylene terephthalate (PET) has become the primary packaging material for many food goods, particularly carbonated beverages, and bottled water, as well as chemical industry packaging of various hygiene maintenance agents, insecticides, solvents, and so on. PET provides excellent strength and permeability capabilities for packaging beverages, as well as excellent chemical resistance and transparency. During the thermoforming of PET containers, acetaldehyde (AA) and formaldehyde (FA) are produced. Acetaldehyde and formaldehyde remain trapped in the walls of a PET container after cooling and may migrate into the water after filling and storing. The primary goal of this paper is to investigate the amounts of acetaldehyde and formaldehyde residues in polyethylene terephthalate bottled water and their implications for consumer health. The migration of acetaldehyde (AA) and formaldehyde (FA) from PET bottles into mineral carbonated water was determined in this study using a UV double-beam spectrophotometer method. A default test is also performed to check the pH of the water to determine whether the water is acidic or basic solution, a TDS of water test is performed to determine the total concentration of dissolved substances in drinking water, and an electrical conductivity test is performed to determine how well the water.
