Description
Citric Acid – USP/FCC Grade
Citric Acid is a premium USP and FCC grade white crystalline powder that dissolves easily in water. This odorless, highly pure acid occurs naturally in plants and animals as part of the Krebs (Citric Acid) cycle and is responsible for the characteristic tartness of citrus fruits.
Our citric acid serves as a versatile ingredient across food, beverage, cosmetic, and cleaning industries. It functions as a flavor enhancer, preservative, and pH adjuster, and also works as a mild, effective stainless steel cleaner.
For cleaning: dissolve in warm water to remove mineral deposits, limescale, and tarnish from stainless steel. Always test on a small area first and avoid natural stone surfaces such as marble or granite.
Storage: Keep sealed in a cool, dry place; avoid moisture and incompatible materials.
USP/FCC Grade Water-Soluble Food & Industrial Use
Grade: USP / FCC — food & beverage compliant.
Solubility: Highly water-soluble for rapid dissolution.
