What are impurities in soft drink?

Impurities in soft drinks can include unwanted substances such as contaminants, additives, or residual chemicals that are not part of the intended formulation. These can arise from the ingredients used, the manufacturing process, or environmental factors. Common impurities might include pesticides, heavy metals, or microbial contamination, which can affect the drink's safety and quality. Regulatory bodies typically set limits on these impurities to ensure consumer safety.
