Emphasis on Food Grade Use + Safety Standards

Phosphoric Acid (H₃PO₄) is a vital ingredient in the food industry, valued for its acidity regulation, flavor enhancement, and preservative functions. Food-grade phosphoric acid must meet strict purity requirements, especially regarding heavy metal content, color, and microbial safety. Dongguan Weiqi Chemical provides high-quality food-grade phosphoric acid that complies with FCC, E340, and international food additive standards.

In beverage manufacturing, phosphoric acid provides a sharp, refreshing acidity that balances sweetness and enhances flavor stability. It is widely used in cola drinks, fruit drinks, flavored water, and sports beverages. Its ability to maintain consistent pH helps prolong shelf life and preserve taste.

Phosphoric acid also plays a role in dairy processing. It is used in cheese emulsification, helping stabilize texture and improve meltability in processed cheese. In sugar refining, phosphoric acid assists in clarifying syrups and removing impurities.

Beyond beverages and dairy, phosphoric acid is used as a pH adjuster in jams, sauces, and condiments. It supports microbial control and maintains product consistency throughout shelf life.

Safety is a major factor in food-grade acid. Our phosphoric acid goes through rigorous quality testing, including heavy metal analysis (arsenic, lead, cadmium), chloride content control, and color index testing. We ensure each batch meets international food safety regulations before shipment.

Packaging options include IBC tanks, drums, and smaller containers for food manufacturers requiring high-purity ingredients. Stable supply and competitive pricing allow us to serve beverage factories, food processors, distributors, and importers globally.
