Phosphate Acid FOOD GRADE TECHNICAL GRADE

Phosphate Acid
CAS NO:7664-38-2
EC NO:231-633-2
Molecular Formula:H3PO4
Industry phosphate is mainly used on the metal surface steel, phosphate processing, preparation of electrolytic polishing liquid and chemical polishing solution;rubber coagulant for slurry and raw materials for production of inorganic binder; coatings for metal rust.
Food grade Can be used for flavoring agent; for canned food, liquid, solid drinks and soft drinks the sour agent, can replace citric acid, malic acid; in beer saccharification process, can replace the lactic acid to adjust PH value; sugar cane sugar industry for clarification agent; Saccharomyces yeast nutrients used to prevent bacteria breeding; flour for the modifier, but also widely used in high precision electronics industry, pharmaceutical industry.
