Phosphoric Acid 85% Min Food Grade (E338, Orthophosphoric Acid, CAS 7664-38-2) is a colorless, odorless, viscous liquid and one of the most widely used food-grade acidulants, pH regulators, and yeast nutrients in the global food and beverage industry. Manufactured to meet ISO, SGS, FCC, EU 231/2012, and FDA GRAS (21 CFR 184.1005) standards, it delivers consistent purity (≥85% H₃PO₄), ultra-low impurities, and reliable performance for beverage, food processing, bakery, and preservation applications. As a trusted supplier, GNF provides bulk and customized food-grade phosphoric acid with full certifications, stable supply, and competitive pricing for global buyers.
What Is Food Grade Phosphoric Acid 85%?
Food Grade Phosphoric Acid 85% is a highly concentrated aqueous solution of orthophosphoric acid (H₃PO₄) with a minimum purity of 85.0% by weight (typical range: 85.0%–85.5%). It is produced via thermal process or refined wet-process technology, followed by solvent extraction, activated carbon filtration, and precision distillation to remove heavy metals, arsenic, fluoride, and sulfate—ensuring compliance with strict food safety standards.

Core Functions & Industry Applications
Phosphoric Acid 85% Food Grade acts as an acidulant, pH adjuster, flavor enhancer, yeast nutrient, and antimicrobial agent—critical for modern food manufacturing.
1. Beverage Industry (Most Common Use)
-
Carbonated drinks (cola, soda): Provides tartness, balances sweetness, prevents discoloration.
-
Ready-to-drink (RTD) beverages, sports drinks, and bottled water: Controls pH, improves stability.
-
Fruit juices & nectars: Adjusts acidity, extends shelf life.
2. Food Processing & Preservation
-
Canned foods, pickles, and sauces: Lowers pH to inhibit bacteria (e.g., Clostridium botulinum).
-
Bakery & yeast products: Acts as a yeast nutrient, improves dough fermentation and texture.
-
Meat & poultry: Enhances flavor, improves water retention, stabilizes color.
-
Sugar refining: Decolorizes and purifies sucrose.
3. Other Industrial Uses (Food-Safe)
-
Water treatment: Sequesters minerals, prevents scale in food-grade equipment.
-
Pharmaceutical excipients: pH control in oral liquids (GMP-compliant).
-
Agriculture: Liquid fertilizer additive (phosphorus source).
