Why must water and other ingredients used in soft drinks be food grade?

All ingredients used in the production of soft drinks, including water, sugar, carbon dioxide, acids, juices, and flavors, must be of high purity and food grade to ensure the creation of a quality beverage.1

Using food-grade ingredients is a fundamental requirement for maintaining consumer safety and product standards. Water, for instance, is often processed beyond its initial municipal supply state to ensure uniformity and remove impurities, such as bacteria, algae, chlorine, and other unwanted tastes or odors. By adhering to these strict quality standards, manufacturers uphold the ethical principle of providing safe, consumable products to the public.2
