Food grade Phosphoric Acid

1. What is Phosphoric Acid?

Phosphoric acid 85% is a colorless, transparent or slightly light colored, viscous liquid. Melting point 42.35 ℃, specific gravity 1.70, high boiling point acid, can be miscible with water in any ratio. When boiling point 213 ℃, pyrophosphate is generated.
Phosphoric acid or orthophosphate is a common inorganic acid, which is a medium strong acid with the chemical formula H3PO4 and a molecular weight of 98.

2. What is Phosphoric Acid used for?

Food grade phosphoric acid (E338) is an inorganic acid with multiple functions in food processing, mainly used in the following categories: 1 Acidity regulation and flavor enhancement: Phosphoric acid is a key ingredient in carbonated beverages such as cola, providing a refreshing sour taste and balancing sweetness. Its acidity is stronger than citric acid, making it suitable for products with high acid demand. two Preservation and extended shelf life: In meat products such as sausages and ham, phosphoric acid can inhibit microbial growth, improve water retention, and enhance tenderness. three Dairy and baking applications: used in cheese processing to adjust pH and promote solidification; Reacts with sodium bicarbonate in bread as a leavening agent. four Nutritional enhancement assistance: Derivatives such as calcium phosphate can enhance calcium or help minerals dissolve in beverages (such as sports drinks).

3. How to use it?

Dosage: International standards (such as FDA) stipulate that the limit of phosphoric acid is 0.1% -0.5% (depending on the food category). Excessive intake may interfere with calcium metabolism, so strict control is necessary. In addition, some countries require labels to clearly indicate “phosphoric acid” or E338. Attention: High purity (≥ 85%) food grade phosphoric acid should be selected to avoid industrial grade impurities; Uniform mixing is required during processing to prevent local over acidification.
